we'll uh turn the floor over to our amazing uh neurologist host facilitator dr suber
0:06
manian hi everyone welcome it's almost the weekend uh and uh i hope everyone's staying safe
0:13
and doing well and we are still physically unfortunately distanced but socially
0:19
connecting through this virtual modality and thank you to the pmd alliance for hosting and um it's with great pleasure that i um
0:26
bring you a fellow colleague who also is based here in southern california dr lipban
0:33
and i'll be introducing her in a minute she has been in a number of parts of the u.s before
0:38
and i have a lot of close friends that have worked with her before and she just brings such a wealth of information and it's been just nice to
0:45
collaborate with her down here um and it's this is a talk that's uh from a lot of what people have asked for
0:52
um through the series so they've been asking for an understanding of if it's not parkinson's disease
0:58
what else could it be and so we'll be covering some of the atypical parkinson's syndromes or um you know
1:04
there's parkinson's so there's many ways that we talk about this umbrella of parkinsonism and
1:09
dr lipvan will be telling us a little bit about that she has a really interesting background she's sort of
1:14
been all over the world she is originally from uruguay and then she did her medical degree there and then
1:22
did some training in georgetown university in washington dc and also spent time in
1:28
barcelona um did a fellowship in barcelona spain um and so it's just a real wealth of
1:35
information that she brings and she's really been heading up a huge number i was looking at her cv she just has such a wealth of
1:42
research talents and um has really been bringing together people uh to study many of the disorders
1:48
that she'll be talking about today so i wanted to um introduce you and welcome you dr litvan and
1:54
learn a little bit about your journey maybe you could tell us a little bit about how you started in uruguay ended up in barcelona and now in sunny
2:01
southern california what brought you to medicine originally maybe what inspired you as a neurologist
2:06
and also what made you interested in specifically these sorts of disorders
2:13
well i love to help out and so i always felt that being a physician was
2:20
kind of something that i wanted to do or being a nurse either one and as i grew up i started look at the
2:27
brain and i was fascinated with the idea that there were different areas in the brain
2:33
and that each one would have different functions and that when there would be a problem a lesion
2:41
then the person would not have that function and i thought that was important and more importantly i thought
2:48
well perhaps we can do something to make things better and that's kind of
2:54
how i got into research so yes i was born in uruguay and i did
3:02
finish my medical school but there was a dictatorship that came in so i moved to spain but in spain
3:10
um they just were coming out of another dictatorship that was franco and so there was a lot of uh
3:18
revolution in some ways um and eventually everything came
3:24
uh you know it was well and i had a wonderful time uh being a
3:31
fellow over there and do my first obviously doing my residency and then
3:37
doing my fellowship in the best hospital in spain in barcelona
3:44
so when i finished i realized that i wanted to do research and i thought that
3:49
the u.s was the right place so i came to the national institutes of health and i spent many many years there uh
3:56
working and it came to a point that they told me you know if you really want to grow
4:02
further you have to go to academia and so i there was a position in kentucky
4:10
and i thought okay i'm gonna go there and start something i had no idea where kentucky
4:16
was i have to admit uh so it was a whole new thing for me
4:22
and so i end up in louisville at the university of louisville and uh there i established a whole
4:30
woman disorder center and uh and i just very well to the city i was
4:35
really very happy and the people from the university of california told me why
4:42
don't you come and establish the same here and i thought oh i'm not sure i want to
4:48
start all over again but they said just come and see once i
4:53
came here and i saw san diego i said yes i'm coming here i love it
5:00
so i came back to san diego and established a whole movement disorder
5:06
center that i'm very happy because now is a parkinson's foundation center of
5:11
excellence it is a cure psp center of care it is a
5:19
a research center for dementia with louis bodies it is a huntington's cc center we work on dystonia so it is a
5:27
whole uh whole thing of um things happen that we were able to grow
5:35
and uh be successful and i'm really happy with my patients that gave me the
5:41
strength to move forward and all the inspiration that makes me move towards
5:49
doing more research so i can help more that's amazing i think you could go to
5:54
mars and start a center and you'd have [Laughter] humans and every other so you could just
6:03
it's we've had a really great run of powerful women in movement disorders and um i'm proud
6:09
to say that you're one of them we had claudia trunk welder on earlier for world brain day and um she talked
6:14
about the movement disorder society which i know you're a fellow in as well and so we applaud the work and
6:20
and it is a lot of work um to succeed in this field and and put together these things but i'm inspired by your inspiring story
6:27
and it sounds like we're all really inspired by our patients so i think without further ado we will let you
6:33
teach us a little bit about this field i know you put together some slides and we can kind of start there and take some
6:39
questions as we go and learn a little bit more about you know what you do thank you
6:44
so i'll talk about why don't i have pd that is a question that some of my patients ask
6:51
um they said i'm slow i'm stiff i have tremors so why is it that i don't have pd
6:58
um these are my disclosures uh we're just going to share the screen right
7:04
we have to put up the slides oh i thought that i'm sorry i thought that
7:12
that is some you disconnected me from the slides i thought so i thought i was sharing them again
7:19
yeah you just have to go at the bottom and show the screen yeah i'm doing that there you go perfect yeah we got it
7:24
okay all right lovely so hold on a second
7:34
so this is lovely san diego um so these are my disclosures um
7:40
i most of them are related to research and really or therapeutic trials
7:48
and very little is related to industry
7:53
so the key points of today are let's define what parkinsonism is
8:00
so we can understand what the parkinsonian disorders are and let's see how we can classify these
8:07
disorders let's also talk on about a typical parkinsonian disorders and
8:14
differentiate parkinson's from all the typical parkinsonian disorders
8:20
i'll give a few examples at the end if i go too long you let me know okay
8:30
so the most important aspect or the most important feature of
8:37
parkinsonism is slowness or slow loss of amplitude of the movement um
8:44
that you'll see an example in in a second uh it is also the presence of
8:52
either stiffness or tremor and uh this is the patient
8:58
that is doing the finger tapping than many of you may have done and you can
9:06
see that there is slowness and at times that is kind of hard to see
9:13
okay let me let me go from the beginning here these ones are starting on their own so
9:19
this is a patient that has a rest tremor and you can see it here and when he's moving his arms that is
9:26
going to disappear and that is typical of parkinsonism
9:33
the slowness can be also shown as we walk and so this is a person that is
9:38
very slow and it is also having
9:43
uh no movements of the arms and the steps are kind of small
9:50
and that is a little bit of what parkinsonian gait is
9:58
so all these disorders that are parkinsonian disorders have something in common and what they
10:05
have in common is like in the back of the brain you may have heard about some something
10:11
that is called the substantia that is what produces the chemical
10:17
dopamine that makes the motor circuit work dopamine is like gas for a car without
10:24
it it doesn't work well so what happens is a dopamine goes to these
10:31
areas of the brain and then makes it uh the whole
10:38
circuit in order to be able to allow us to walk well
10:45
and you may have heard of that scans and so some people say okay if i get at
10:50
that scan will i be able to know what i have well you would know
10:57
that you have parkinsonism but it doesn't really tell you what disease you have so
11:04
as you see these areas in the brain the nuclei
11:10
sorry you can see here the same thing and this is a normal uh
11:18
coded that is the deep area in the brain and this one is an abnormal one you can
11:25
see that there is something that is missing here
11:31
that is related to lack of chemical dopamine that comes to the brain
11:40
so what are the parkinsonian disorders well these are diseases in which we have
11:47
parkinsonism and we basically divide them in two major groups
11:54
secondary secondary to a cause that we can identify and that's why we ask you what are your
12:01
medications have you had a little stroke have you had some infections
12:07
etc etc because these kind of help us figure out if there is something that
12:13
we can identify and treat right away but if there is nothing like that
12:21
and the disease is kind of presents gradually and slowly pretty much
12:27
is what happens when we have a neurodegenerative disease it's a big fancy name to basically say
12:36
that cells in the brain die and die much earlier
12:42
when they should as we age so all these diseases that are
12:48
neurodegenerative can be divided into uh main ones parkinson's disease and these
12:55
ones that are called atypical parkinsonian disorders and there are many there are
13:03
sporadic diseases diseases that don't have family members within with a illness um and that
13:10
is progressive supernuclear policy psp uh that is something more
13:18
more known as psp multiple system atrophy msa cortical basal degeneration cbd
13:26
dementia with lewy bodies dlb or lewy body disease and then there are
13:32
familial uh diseases like frontotemporal dementia with parkinsonism
13:39
this is just to let you know it's not that you need to learn all these all these fancy names
13:47
so the important aspect here of knowing what disease is is
13:53
what allows us to know what is the protein that deposits into the brain
14:00
the the protein that deposits into the brain in parkinson's disease in multiple
14:06
system atrophy and in lewy body dementia is called alpha nuclei this protein
14:14
is very important but what is more important is that it allows us to diagnose a
14:22
disease if we do newer studies that are to look at the spinal fluid and
14:30
measure alpha nuclei this is still not um available
14:38
for commercial but it is in research and likely is going to go uh into the market
14:45
but in addition and more importantly is that we can develop and we are
14:51
developing treatments to try to slow all these diseases that have alpha
14:57
nuclei so if we know that is one of these three diseases
15:03
perhaps we can try to find eventually a
15:08
treatment that can slow or stop the illness the other protein that deposits in psp
15:16
and in cbd is called tau tau is another protein that is kind of
15:22
what forms the walls of the cells that the walls of the pipes that
15:29
nourish the cells and if it's not functioning well
15:36
of course the cell is gonna die and that is pretty much what happens and again
15:42
we're having multiple treatments that are being looked at to try to see if any of them
15:51
can help slow these diseases
15:56
there are these other ones several other ones that i'm not going to mention because i'm not going to discuss them
16:02
and that have other proteins and we don't have treatments for those yet experimentally
16:12
so what is anatypical parkinsonism so while we can define
16:20
parkinson's disease as having the slowness with or without tremor or rigidity
16:29
the typical parkinsonian disorders have more than that they have early on
16:36
problems with walking problems with balance and in addition they have problems that
16:43
do not occur in people that have parkinson's disease
16:49
so i'm gonna tell you what are the differences between one and another uh although i'm not
16:56
gonna be able to go over all the differences uh but i'm gonna go into several so you can get a sense of what's
17:04
going on so if we give a person that has parkinson's
17:11
levodopa or requip or pramipex or whatever it is that you that you administer
17:19
it makes all these motorcycles that i told you
17:26
work because it's replacing that dopamine that we normally have so the patients
17:33
respond beautifully because that is a major aspect of the motor problems that
17:39
patients with parkinson's have they don't have so many other problems regarding motor uh motor problems there
17:48
are other problems without any any doubt and as the disease progresses
17:53
some of the things that happens in a typical parkinsonian disorders may happen in parkinson's
18:01
but one thing that does not happen is what happens in the typical parkinsonian disorders
18:07
there is lack of benefit there is no benefit the person stays about the same
18:14
initially may respond minimally or mildly but not a major major benefit as
18:21
we see with parkinson's disease another difference is that while in
18:29
parkinson's the diseases progresses in a slow way uh
18:34
this does not happen with the typical parkinsonian disorders for
18:40
example early on we can have problems with balance
18:46
people that just fall without knowing why they fall uh because there is not
18:53
that they had an accident it's not that they didn't see something or have other clearly
19:01
problems such as having problems with the knees or the the hip or
19:09
something that would explain that fall
19:14
then um those people may have what we call one of the symptoms of the
19:21
typical parkinsonian disorders in parkinson's on the other hand as you
19:27
saw in that patient that i showed you earlier they may walk slowly may have slow steps
19:34
but there are no problems with balance or fall for many many years
19:44
so here you can see a patient of mine who actually was not working so bad
19:52
but she has an abnormal posture and also she has no balance as i minimally
19:59
touch her she falls and she cannot recover she also has uh the skin with a red
20:07
color that if she puts the legs
20:12
horizontally that disappears that is those are the symptoms that have to
20:20
do uh this one in particular with the autonomic system and i'll talk about that later on
20:29
what are the differences so
20:35
another difference is that patients with the other parkinsonian disorders may
20:42
walk like if they were inaugurated uh this is not the one i wanted to show
20:48
you so let me show you the one i want to show you i'll go back to the to the other one so you can see that
20:54
this person is unstable but also on when the legs are really separated
21:01
from each other at times it's hard to see but but you clearly can see that overall
21:07
the legs are separated um and that is not something that we see in
21:13
parkinson's disease let me go backwards now
21:23
freezing can occur in parkinson's disease usually does not occur early but this
21:30
patient had freezing for many many years and ended up having
21:35
another disease that is psp so it is a different
21:41
story altogether because freezing walking was her major problem she didn't
21:48
have any other problem freezing was it
21:57
so we talked about the rapid progression so one of the things that could happen is
22:03
that we can see a patient early on coming in a wheelchair
22:09
um and having like a fracture and that kind of let us know that this
22:15
patient does not have in parkinson's uh so we already know as the patient
22:21
comes in into the office that this is not parkinson's disease
22:27
again there is a slow progression in parkinson's dc so
22:34
we don't see many people walking with uh going into a wheelchair and if they do
22:41
is when the disease is quite advanced and they may come in a wheelchair but
22:46
then they leave walking normally um because now the
22:51
levodopa is working or the another medication that makes the motor circle work
23:03
so in this a typical parkinsonian disorders there
23:09
are problems moving the eyes it could be up and down it could be horizontally
23:16
um there is also a clear difficulty with reading that is beyond what we have as we age
23:25
and that doesn't happen in parkinson's disease and i'm going to show you a little bit of a patient that had psp
23:33
um and he was able to follow horizontally that pen
23:40
but you're going to see that he's unable to follow it in the vertical direction and that
23:48
is um why the disease is called supranuclear policy
23:55
because there are lesions that are above of where the uh the nuclei the areas
24:02
for the nerves that go to the eye are and make both eyes not being able to
24:09
to move appropriately and we can confirm it because if we move
24:16
the head up and down we can see that the eyes move like a you will see in adults
24:24
and that is what we call the doll's head maneuver
24:30
he wants to see his watch but he's unable to do so and the same uh perhaps move in the eyes
24:38
but not really like that because they go up but in any case um moving his his arm is how he's going
24:45
to truly see it there could be that
24:52
the person has a stiffness i may say that they have tremor when not
25:00
doing anything as we saw tremor at rest in the patient with parkinson's disease being slow
25:08
but in the typical parkinsonian disorders there may be a lack of ability to use
25:16
a hand or a leg or uh there could be a
25:23
difficulty having special abnormal postures
25:30
and here actually this patient of mine was a policeman who had
25:36
lost the ability of using his gun and that was his first symptom and then
25:43
he developed these abnormal movements that you saw
25:48
and there are several here um the the difficulty that he has extending
25:56
his arms and how he has his fingers and also that little jump
26:02
that he has none of that we usually see in parkinson's however i'm gonna clarify something
26:10
in people that have young parkinson's disease at times we do see uh this abnormal posture
26:18
what we call dystonia and that improves uh with the levodopa the dopamine
26:27
agonist but this one that this patient has does not improve with anything
26:33
so it's a different one it could be that patients may have
26:40
dementia early on they may see things that are not there
26:46
they may have problems talking may find a significant difficulty
26:53
saying words and that is not what happens in parkinson's in
26:59
parkinson's recognition in in general is normal
27:05
there may be some difficulties multitasking or perhaps planning there can be some
27:11
depression some anxiety but unless they have
27:16
some medications they don't have hallucinations the hallucinations that we see in
27:24
typical parkinsonian disorders are hallucinations without
27:29
any medication whatsoever or any reason whatsoever is that scary for you in some
27:36
ways that's sort of interesting okay what are the interesting things you
27:44
see oh faces and colors things that are attractive people that
27:52
you know yeah sometimes and other times
28:00
okay so you saw that uh this was a patient that had dementia
28:06
with lewy bodies and we'll talk about that briefly later and hallucinations early on without any
28:13
medication or any reason occur may occur early on
28:20
so on the other hand here we have that in parkinson's disease people
28:28
act out the dreams normally when we sleep we don't move when we
28:35
dream but what happens in parkinson's is that
28:42
we can act out the dreams and if the dreams are really bad then we're trying to defend ourselves
28:49
uh because we don't want to be attacked and then we can either hurt someone or fall to this the floor or hurt
28:57
ourselves in in different ways that is not usually present
29:02
in the typical parkinsonian disorders and i'm going to show you this because
29:08
actually this is one of the early signs of parkinson's disease
29:14
this may not happen on everybody but may happen many many years
29:20
before someone developed parkinson's disease
29:26
so he's having a bad dream and obviously he's trying to defend himself so this
29:33
is why he's doing this at times the patient may awake and at times continue sleeping and in this case
29:40
also continue sleeping so now let me summarize a little bit
29:49
and give you a little bit of a glimpse of what is some what what are the features
29:57
of some of these disorders and i'm starting with psp because it's the most common one
30:05
so these patients present with early balance problems and falls that is extremely
30:12
common they may have this parkinsonism the slowness the stiffness but usually
30:20
instead of being a lot of the limbs as in parkinson's is more on the
30:26
axial areas it's more in the walking is more uh related to the neck areas
30:33
that are completely different in addition as i mentioned these patients unfortunately do not
30:40
benefit from the dopamine medication and they don't benefit because
30:47
not only that lesion that i show you initially was present the substantia
30:53
lesion that leads to not having dopamine but there are also
30:58
lesions in other uh areas of the brain that are part of that motor uh
31:05
circle therefore uh if we give dopamine it's not good enough
31:12
and this would be like you know the problem is that you don't have gas and you don't have
31:18
oil you can put gas but if there is no oil the car is not going to work and here is
31:25
something like that the only problem is that we don't know what are the other chemicals that we
31:32
would need to use in this case as the patient that i
31:38
showed you before there is difficult to move difficulty moving the eyes and at times this is the
31:45
first problem but most of the patients don't have that
31:50
and there is problems with speech it's like um it comes difficult uh
31:57
in enunciate the words and there may be problems swallowing and at times
32:05
there is a more significant and that is common actually to have much more difficulty with
32:13
what we call the frontal lobe that is the areas in the brain that pretty much
32:19
coordinate the rest of the brain it's kind of the conductor of the brain
32:24
and so that's why these functions are called executive because it is like an
32:31
executive uh functioning that is problems planning
32:37
problems uh multitasking so these things that an executive would do
32:46
your main problems well i fall out and i lose my balance
32:54
and i don't have any speech and i write terrible what was the first problem you
33:01
had falling so that's kind of the typical
33:06
history of a patient with psp so now a glimpse of multiple system
33:13
atrophy so the major problem in this disease is the autonomic system
33:21
that is having lesions and the autonomic system is pretty much the nerves that go
33:28
to the different organs so that's why the urine is one of the same
33:35
the the function of the urinary system is one of the problems and so there could be some urgency and
33:42
eventually incontinence or retention of urine without having any prostate problems
33:50
there could be erectile dysfunction and they could be as well a drop of the blood pressure
33:58
when standing and that can be very very significant
34:03
and gives a lot of problems being extremely fatigued
34:08
having pain in the back of the neck feeling like you're gonna faint
34:13
or fainting having a single event so if in addition we have the other
34:21
features that we talk about parkinsonism then this is multiple system atrophy
34:27
with parkinsonism msap is called and it has all the features that we just went over
34:36
on the other hand if they have cerebellar problems that is that inhibited walk
34:43
being extremely coordinated and in coordinated and having problems with
34:50
speech then we have a multiple system atrophy with cerebellar symptoms and i'm going
34:57
to show you a little bit of this problems with incontinence uh
35:02
impotence was that a problem also
35:09
feeling woozy that's not been much of a problem your
35:16
blood pressure was when you were lying down 167 over 79
35:22
but then when you when you got up your blood pressure came to be 95 or 59 so it really the reason
35:29
fluctuated a lot so people think oh it's fluctuations but reality is
35:35
that the blood pressure drops in significant ways and that's why not enough blood goes to the brain and
35:43
so the person has all these symptoms
35:54
so that is kind of a speech that is different that occurs in cerebellar disorders and this patient
36:02
in four years went from walking to being wheelchair bound
36:10
so this patient has the incoordination that i was trying to tell you that is a little bit different than the
36:17
tremor itself if you see there is a little bit of difficulty that goes beyond
36:25
and it's difficult at times for her to find where is that that finger that is
36:31
different than a real tremor
36:37
so what happens with dementia with lewy bodies well the major problem is the dementia that
36:43
could be just what we said before having problems that are executive
36:51
having fluctuations like one day i'm functioning beautifully and the other day i'm so confused that
36:58
it's really hard seeing things that are not there not related to medication
37:05
having parkinsonism and here is also enacting the dreams
37:13
so in summary parkinsonism is a combination of slowness stiffness tremor
37:21
and balance problems but persons with atypical parkinsonian
37:26
disorders have that parkinsonism plus other problems that patients with
37:34
parkinson's do not have and i briefly pointed the problems
37:41
that persons with psp msa and dlb that are the most frequent a
37:48
typical parkinsonian disorders have so thank you very much
37:57
thank you that was great um so let's uh maybe just um we can stop
38:02
sharing those uh slides and we can reconnect that's perfect so we have a number of questions um
38:09
irene uh i think uh it was a really thorough um presentation and just so i can summarize a little bit um so it
38:16
sounds like you know the ways that we can approach parkinson's patients so there's this umbrella of people that look like parkinsonians so
38:23
they're stiff and sometimes um you know slow and sometimes have a tremor but then there's
38:29
these other things that kind of are red flags as doctors that should point us in
38:34
a direction that might be different than parkinson's disease one of them is that the response to medications um
38:41
with classic parkinson's is quite robust many symptoms do respond um
38:46
really really well to levodopa and that response lasts for many many years with the atypical
38:52
parkinson's um it sounds like that's not the case when we can some of the questions ask about
38:57
the response to leave it over so we'll clarify then there's a number of things i wrote down that kind of are
39:02
red flags like you said the wide base gate early on eye movement issues early on where we
39:08
can't look up especially or down when the hand gets dystonic or tight
39:14
early on um and not responsive to medications early cognitive changes
39:20
early hallucinations that are early like in the first couple of years of the parkinson's early
39:27
falling so if somebody presents to a doctor and they're falling like one of your patients on the video
39:32
right at the beginning then we start questioning is this actually regular parkinson's disease and then it sounds like early speech
39:39
problems and swallowing problems so these are usually not things we see in classic idiopathic
39:45
parkinson's disease early on so if you have these things and you're seeing a doctor
39:50
and you're not really responding to medication and you're feeling like you might have got the diagnosis of parkinson's disease
39:56
maybe revisit that and maybe try to see some you know expert maybe like a movement disorder specialist or definitely a
40:02
neurologist if you're not seeing one um so that you can get a little bit more guidance does that sound about
40:07
right absolutely yes and i see some of the questions yeah i can kind of i i can sort those
40:14
out don't worry about those um so one of the questions um just to clarify because there were some words i think early on um one of the
40:22
questions was um does where do things like dopa responsive dystonia fit
40:27
in the classification another question was about vascular parkinsonism where does that
40:33
fit um in in this sort of stuff and then one one of the questions was also um about clarifying what
40:40
familial is because it was on one of your slides so maybe we can um find out about dope responsive and
40:46
vascular parkinsonism where would those fit so in parkinson's disease particularly
40:53
early on you may have an abnormal posture of the hand and you may have
40:59
an abnormal posture of the leg when you walk
41:04
and at times is when you walk a lot at times it's only when you're running
41:09
and eventually when we adjust the medications that abnormal posture
41:17
goes away the majority of the times um it could be that some
41:23
people may not but in general it goes away and the person has many
41:29
many years doing very very well that by the way
41:34
the dopamine response in parkinson's is forever
41:41
it may well be that because this certain medications such
41:48
as cinnamon doesn't last long then initially
41:55
it may happen that we have other neurons that are storing
42:03
the dopamine and so it may last many many hours but because
42:10
the levodopa lasts normally as in cinema uh
42:17
an hour and a half um when the disease progresses then
42:24
the medication lasts less but this is not a problem that the disease
42:30
makes it not to work the problem in the majority of the situations is that
42:37
the medication doesn't last enough so there are nowhere medications that last
42:43
longer such as right tariff for example and then that happens much
42:50
much later because the retiree lasts five hours
42:55
as an example so that i wanted to mention because many people reading the
43:02
internet that oh you try livodopa and then it goes you know you you end up
43:09
not functioning it doesn't work yes it always works it just happens to
43:15
be that it works for less amount of time so that was related to
43:21
and related to what i was asked the first one was the dystonia and what was the second one
43:28
um vascular so there was dope dopa responsive dystonia and then vascular okay so the dopa the
43:36
uh response estonia is what i just explained before that is the dystonia
43:42
that responds to cinnamon or libodopa uh or dopamine agonists like requip
43:50
pramipexo all right so
43:55
vascular parkinsonism is in fact one of the secondary uh
44:02
disorders because we have a cause and the cause is the multiple strokes
44:09
that lead to that parkinsonism so as i mentioned before there are
44:16
certain areas of the brain that lead to a function so if we have a
44:22
stroke in the area that has to do with language we may not be able to speak well
44:29
here if we have little strokes in the areas that had to do with the
44:35
motor circle then we may not be able to function
44:43
as normally and we would become having vascular parkinsonism the vascular
44:50
parkinsonism i didn't talk but the person walks with
44:57
a wide back wide gate with the legs separated as i show
45:03
you before in the inaugurated there is postural instability and the problems
45:12
are mostly in the legs the arms are pretty pretty good that is
45:17
very different than in parkinson's that the arm and the leg or the in the
45:23
typical parkinsonian disorders that eventually the arm and the leg are
45:28
affected so that goes for vascular parkinsonism
45:35
we can diagnose that based on the history based on mris uh when we do an mri of
45:43
the brain okay and the treatment is mostly physical therapy
45:48
just in case go ahead okay perfect um there's just a clarification or two about um other syndromes this is a very
45:55
educated bunch so um they've been watching a lot of these videos um just you know so they were
46:01
just asking about rem behavior disorder because um we had a speaker just speaking about that and they they they know that it's also sometimes
46:08
seen and you mention this also in lewy body disease um and there's also a question about whether that can be seen in multiple
46:14
system atrophy as well yes absolutely i'm sorry i think i was misleading you on that one and that was
46:21
my error because i was thinking mostly on psp and in cortical basal degeneration where
46:27
that does not occur but certainly in dementia with your bodies and in multiple systematrophy
46:35
those are uh also that are the diseases that have problems with
46:43
um deposits of alphas in nuclear in all those diseases ram behavior
46:49
disorder occurs that is the enacting of the dreams perfect and you showed us that beautiful
46:55
video that's so interesting um so there's been a few questions about um sort of
47:00
early on in in in presentation whether sometimes cinematic is added and sometimes people
47:06
can have a response and then maybe they lose that response um the question is you know
47:11
is there actually response is there a placebo effect should people get off the levodopa if
47:16
after some time if they end up feeling like you know maybe they didn't end up having parkinson's sort of what's your sense of
47:23
that well what happens is that when we give the levodopa and someone
47:30
does beautifully this is because we're giving the
47:35
chemical that is needed to make the motor circle work um
47:41
so if we take it away the motor circle is not going to work
47:47
this is like you know saying well is gas for a car a placebo effect no it isn't if you
47:54
don't put gas it doesn't work period and here it is the same
47:59
we have a decrease on the amount of of dopamine and the levodopa converts
48:07
into dopamine so it is very important to continue the
48:13
medication it is like uh for type people that have diabetes
48:19
they have to when they use insulin in general particularly those that have diabetes
48:25
when they are kids uh or very young they have to use insulin all their lives
48:33
so there are certain things that you feel great but you're feeling great
48:41
because you're taking medication which is uh really a blessing to be able to do
48:48
well with medication okay that sounds good so there's a question about um i guess
48:54
it's sort of more like a biomarker question um we've had actually chuck adler came
49:00
on and talked about some of his studies with parkinson's and even the brain donation he gave a really nice talk for us
49:06
there's been a question about whether um skin biopsies and other biopsies in the parkinson's plus disorders might be
49:14
helpful not yet these are things that are being experimental
49:20
and are being used uh but still we don't have uh real good ways of making diagnosis in
49:28
that way however uh while we cannot do
49:33
that i mean the problem is that the typical parkinsonian disorders there are different proteins it's not
49:40
just one as in parkinson's and so you can generalize uh but in some
49:46
of the parkinsonian disorders such as psp and cortical basal degeneration
49:52
there are ligands that bind to the proteins in the brain that have
49:58
tau and we can see those in pet scans as we can see the amyloid
50:07
in alzheimer's disease so it is still a question of
50:14
being exploratory and in research but more and more there are
50:21
better uh ligands that are allowing us to see much better the brain
50:28
so eventually we may be able to diagnose early these two diseases by using a pet scan
50:36
not yet okay that doesn't occur for parkinson's or msa go ahead
50:43
um so a question just i think there's been an interest in learning a little bit about research and
50:48
um what are your most exciting kind of prospects in terms of the research that's happening
50:54
in this area for patients with atypical parkinson's syndromes so the most
51:00
exciting thing for me is to see that we are starting to have treatments for patients
51:08
that have the typical parkinsonian disorders so we are doing a lot of treatments
51:15
for patients that have psp because we can diagnose them very very well
51:21
it may take us a little bit to diagnose them uh it will be better once we have the pet
51:27
scan with that ligand for tau but we can diagnose them well
51:32
so industry instead of using so much all these
51:38
efforts in treating alzheimer's disease realize that in psp
51:45
there is only one protein that deposits into the brain and it may well be much easier to find a
51:53
solution than an alzheimer that has two proteins tau and beta amyloid so
52:02
there are many studies and one of them uh we're we're doing we just finished two of them
52:08
that unfortunately didn't work but we're having a third one that is coming up
52:13
um that is antibodies against that the tau uh so i don't know if you
52:20
went over some of these things or not but the disease uh progresses going from
52:26
one cell to another did you go over all that because i don't want to
52:31
no not about the atypicals but in parkinson's we have talked with dr lang came on and talked about this
52:37
you know the um alpha nuclean type antibody treatments and then alberto
52:42
gave a very complicated talk on you know how a lot of the pathology may not have anything to do with ashley the way that
52:49
we've had a lot of different people that have talked about things but if you'd like to describe that for a minute or two we
52:54
have about five minutes left so happy to have you you know teach us a little bit about that so what happens
53:01
in psp as in parkinson's disease is that several studies in animal models
53:09
have shown that if you put the brain of a person that had the
53:15
disease and you put that that's those areas that were affected into a mouse
53:21
uh the mouse develops the exact same lesion that occurs in in the human person and also
53:30
starts to uh go from one cell to another and that is and spreads so
53:37
it became clear then that the disease goes from one cell to another
53:42
how does that happen so what happens is that the protein
53:49
kind of falls in abnormal shapes and because of that
53:56
uh the functions change in the cell and they start to bind to each other and
54:02
when they bind to each other eventually they go with
54:07
and because they still communicate they are sick but not dead the
54:14
proteins can go from one neuron to another neuron um
54:20
so the idea of antibodies is to use the antibodies to try to
54:27
rescue or actually to take uh to get rid of to rescue to get rid of
54:35
all these abnormal proteins that deposit into the brain and get them out of course not all of
54:41
them are going to be gone but the important part here
54:47
is that we take away the part of the protein that is abnormal
54:54
and is the one that leads to the spread and apparently
55:01
the antibodies that we just finished using that fail unfortunately
55:08
went to the part of the tao protein that actually was not the
55:14
responsible of moving from one cell to another
55:20
okay so it sounds like there's clumping there's proteins that are folding weirdly they clump together then they
55:26
affect the cells near them to make them also fold weirdly and clump abnormally so we're trying to attack
55:32
some part of the protein that is responsible for this spreading and bad clumping but we
55:38
haven't quite found exactly where to attack um and we're looking for the right place for the antibody to
55:44
be attacking and so you have some hope that um we can do this in in not only
55:50
possibly parkinson's like dr lang was talking about but also in things that affect the other protein
55:56
which is the tau protein like in psp so that's really exciting so so i think we have two minutes um irene
56:02
uh i was hoping to um just have you give some hope and sort of a message of closure um
56:08
for our group here there's a lot of activists a lot of people who want to get involved in research um and so maybe you
56:14
could just tell us about you know what you think would be sort of the best way for them to to kind of improve their um outcome well i think
56:22
research is the best thing that can happen uh and particularly at this
56:27
time is in particular in parkinson's disease more than any other disease
56:34
i think it is the best time because of uh three things one is
56:41
that we saw in patients that the symptoms go precede
56:48
the development of the non-motor symptoms such as depression the brain
56:53
behavior disorder uh constipation etc and all those
56:59
develop ears lack of smell uh years before the motor symptoms
57:07
so that shows what are the areas affected
57:13
uh and that they are affected uh very early and there is
57:21
a phenomenal study that show using different pet scans for the
57:27
different uh chemicals that are in the different areas of the brain how patients that had only rem behavior
57:35
disorder compared to those that had parkinson's disease
57:42
they had all these same areas affected except those that had to do with the
57:49
motor system so it is clear how the
57:55
the disease is progressing uh and then when we look at pathology the
58:02
same happens so i think that this is kind of the
58:08
and if we do experiments uh as the one that i mentioned for for uh psp
58:15
and cortical basal degeneration if we do experiments with a brain of somebody that had parkinson's
58:22
and we put it into uh into a mice and the disease has the same lesion and spreads so
58:30
we have evidence from pathology we have evidence from the clinical symptoms and we have
58:38
evidence from the physiology that all that is going in the same direction
58:45
this is the first time that we can see how all the research is showing us a
58:53
path so now it comes our time to try to search for the what is the medication that
59:01
would be the best one and there are several opportunities multiple
59:06
in fact uh one of them is the antibodies another one is to act
59:13
over the proteins that are that are abnormal um
59:19
so there so there's genetic uh ways nowadays that are being
59:26
experimented uh in animal models so i think
59:31
that this is extremely exciting to see that finally
59:37
it's not just that we do this little treatment but we don't know much about it it's just that we saw that there was
59:44
oxidation and so we use an antioxidant we saw this and we use that here there is a whole um
59:53
amount of data that are going in the same direction so it seems like we're on the right path
1:00:01
and that is something that is for me at least i never thought i would see all this so
1:00:06
i'm very very excited um as well so how can
1:00:12
you help or there are multiple ways in which you can help you can help participate in research uh
1:00:19
you can help by spreading the voice about uh the disease and
1:00:25
making people aware that exist many people i would say incredible amount of people
1:00:31
have no idea that this is exist or even that
1:00:36
parkinson's can be treated or even that parkinson's are not
1:00:42
people that the first year of the disease are going to be wheelchair bound so when we
1:00:48
give the diagnosis to someone that they have parkinson's disease it's
1:00:54
almost like giving the diagnosis of having cancer that you have just a
1:00:59
very short period of time to live and your life came apart and i think
1:01:05
uh fortunately there are several ways of improving that so educating is extremely important
1:01:14
and then uh lobbying you can lobby in with your congressman and just
1:01:21
say we want funding for our disease more funding is needed as there is need
1:01:28
you know funding that goes to research with alzheimer's we want also funding go to go
1:01:36
to research such as parkinson's disease so there's a myriad of ways and of course donating the brain
1:01:46
when the time comes is another way so i can't um stress so much
1:01:53
more how you and us uh can go together and
1:01:59
being really uh trying to search for ways in which in which we can improve
1:02:08
uh the care of these diseases and hopefully diagnose them early and hopefully
1:02:14
finding a treatment that's slow stop them or diagnosing them so early so
1:02:20
early that perhaps we have brain behavior disorder and that's about it you know that would be lovely
1:02:27
absolutely well that's very inspirational um irene there's been a lot of positive comments they want you back they want to
1:02:34
do two hours with you next time or something i don't know it's like we could spend all day on here but um such an interesting area and so much
1:02:40
hope and research going on and you're leading so much of it so i'm so proud of you and
1:02:46
continue to and be inspired by you so thank you so much for spending the time i know you're very busy
1:02:51
and um i'll hand it back to you andrea for our goodbye wave yes thank you so much for inviting me it
1:02:58
was lovely to be with all of you and to receive all these very intelligent questions
1:03:07
very good well we always show our gratitude with a wave so if you put your camera
1:03:13
on and if you switch it to gallery view you can scroll through and if everyone can show their
1:03:20
appreciation for dr lipbin and as always dr subramanian thank you everyone for joining great questions
1:03:28
this was excellent to spend this hour learning with all of you bye lovely
1:03:35
bye
