Curing Alzheimer’s with Science and Song | Rudy Tanzi & Chris Mann | TEDxNatick


I’m going to talk to you today about an

absolutely horrendous and devastating

disease that slowly and steadily

destroys the brain erases the mind and

the entire time loved ones of the

patient can only watch on helplessly as

this horror unfolds I’m talking about

Alzheimer’s disease this is a quiet

thief in the night that relentlessly

robs from the patient first the sense of

identity personality and ultimately the

very essence of self it’s about the

worst thing you can imagine facing after

you’ve lived an entire life of wonders

and experiences with your loved ones and

if that doesn’t sound bad enough I’m

going to tell you that I’ve learned just

feel 35 years and the bad news is we’ve

been approaching this disease all along

we’ve made lots of mistakes but luckily

there have also been many victories and

many discoveries with those mistakes and

as scientists the really cool thing

about being a scientist is that the most

important thing you can do is learn from

your mistakes and learn how to do things

better and on that note I can tell you

that right now

based on our mistakes the opportunity

has never been greater to stop this

disease in this next generation in our

lifetime maybe even by 2025 and I want

to tell you about this story but I’m

also going to tell you that families

patients caregivers loved ones the

medical and scientific communities and

especially the FDA all have to talk to

each other work together and listen to

get the job done by the time I’m

finished speaking I hope you get the

same since I do that there’s a lot of

reason to be optimistic what the future

there are 5.4 million patients in this

country today and worldwide there are 50

million and that 50 million is going to

be the number we have in this country by

2050 if we don’t do something about this

disease because right now we’re treating

the disease with drugs that temporarily

effect the symptoms modestly modest

benefit for a short while now right now

the current lifespan is close to 80

years old we’re living longer than ever

but the problem is a lifespan has now

outpacing our health span especially the

health span of our brains all of modern

medicine has us living longer but is our

brain keeping up that’s what we have to

face right now we’re going to be in big

big trouble going forward and that’s

because 40% of people at 85 years old

have symptoms of Alzheimer’s disease so

think about that 80 is the life span

right now that’s going to go up to 85 40

percent is I mean everyone born soon is

going to have a 40% chance of getting

this disease especially such a

devastating disease and right now there

are 71 million baby boomers like myself

all in one big group heading toward that

risk age Alzheimer’s right now sucks up

one in five dollars of Medicare and

Medicaid and as these baby boomers age

that’s going to jump up to one and four

and then one in three and eventually if

we don’t do anything about this disease

Alzheimer’s will single-handedly

collapse our health care system

economically a disaster so this means

that all of us have to work together to

wake up and do something about it

Alzheimer’s began with dr. Alzheimer dr.

Louis Alzheimer described the case of

Auguste deter who was in a Bavarian

Asylum called Baron schloss which meant

castle of the insane they weren’t

politically correct back then about what

they call their institutions he said she

was a 55 year old woman with memory loss

paranoia delusions hallucinations and he

noted in his journal that she was often

found screaming in the middle of the

night these words

oh god I have lost myself and that’s

what this disease is see all of your

life everything you experience is being

recorded on a hundred billion neurons or

nerve cells in your brain trillions of

connections creating a neuro network

like a tapestry the tapestry of who you

are how you loved ones know you your

personality Alzheimer’s comes in and

slowly rips apart that tapestry thread

by thread never resting until the

tapestry is gone that’s what this

disease is and this is what you’re

hearing and August eat his words there

for 80 years

we only define the disease by what

Alzheimer described in her brain he saw

these plaques these big boulders of

clumps of stuff

that was good and sticky around the

nerve cells he said the nerve cells were

choked inside by tangles that were

actually causing the nerve cells to die

and he also saw that the brain was

reacting to this to all this pathology

and cell death with inflammation that

caused even more nerve cells and for 80

years all we could do was describe the

pathology so in terms of solving the

disease it’s like aliens coming from

space and wanted to figure out football

and they get to the stadium at six

o’clock and the game was at one o’clock

they find a helmet they find a football

they find maybe some dug up turf and

cleat marks and they say okay now let’s

figure out what football is right you

get some clues but you can’t figure it

out and it wasn’t until the 80s and 90s

when I was lucky enough as a student at

Harvard to find the first Alzheimer’s

gene the amyloid precursor protein it

makes the stuff that’s in the amyloid

plaques we found more genes in 1995

called the pre-sentence and it was

another gene found called a bowi

and once these genes were found now

finally we had windows into disease

finally we said we have some real clues

that we could grab on to their eye tell

us how this disease is caused and what

one does with genes is you come up with

drug targets and I’ll use an example

first heart disease we take for granted

that you have to keep your cholesterol

low but did you know that that began

with very rare families who had very

rare genetic mutations

that caused them to have high

cholesterol and when this was observed

the idea came about hey maybe

cholesterol has something to do with

heart disease and now of course we all

manage our cholesterol to avoid heart

disease in our futures in a completely

analogous situation with those first

genes I just showed you from the 80s and

90s taught us was that our cholesterol

so to speak at Alzheimer’s is something

called the amyloid beta protein we call

it a beta for short and it’s this little

tiny protein that gets extruded from

nerve cells it comes from a bigger

protein that gets clipped so picture a

piece of rope in your clip in two spots

and it gets extruded and over time if it

starts to accumulate and form plaques

the idea is that that causes the disease

that’s what all the genetics in the 80s

and 90s told us well so we tested that

the idea was if plaques caused a disease

the plaque should cause the tangles as

these twisted filaments to choke the

inside of the nerve cells they made of a

protein called tau the Greek symbol tau

so we tried to put these genes into mice

for two decades you put in these

Alzheimer’s genes that make the amyloid

plaques and the mice and then you wait

for the mice to get the tangles and rest

of the disease and yeah the mice get

sick but the mouse would have to say my

brain has lots of amyloid plaques but no

tangles so this led to so much confusion

people were fighting back and forth see

it’s not the amyloid it’s the tangles is

at the my toes of tangles what causes

the disease amyloid beta amyloid protein

is called B AP so there were two

baptists and then there were the talus

and they would fight grown men fighting

like children at meetings and it was

because we’re doing experiments and mice

and many of us argued very simply hey

you know what we’re not 150-pound mice

you know maybe there’s some difference

between a mouse and a human if you just

kind of look at them

why don’t you would it be nice to be

able to use a human brain well with the

advent of stem cells now we can build

human brains in a dish and this is

exactly what my colleagues at Mass

General did particularly do young

he was able to take stem cells from

humans human stem cells create nerve

cells you see there on the side of the

panel and now if you grow them in a gel

because the brain is like jello if you

grow them in a gel that mimics the brain

the nerve cells start interacting and

talking to each other and creating neuro

networks just like in a real brain and

if you put those Alzheimer’s genes in

the same ones we tried in the mice put

those into the cells and have them make

amyloid you see in the middle panel that

orange dot in the middle that’s a plaque

for the first time you can make a plaque

the plaque was being formed in a mini

little brain in a petri dish Alzheimer’s

in the dish human brain organoids but

the beautiful thing was it took about

six weeks for that plaque to form six

weeks versus you know decades in a human

and if you wait a little longer then you

see the tangles reowww tangles that kill

the nerve cells something we couldn’t do

in mice and if you use drugs that stop

the plaques in the dish in the brain you

don’t get the tangles so this said to us

yes finally debate over plaques cause

the tangles and that said to us well if

we can stop the plaques then we stopped

Alzheimer’s disease it’s that simple

right well we tried that and the answer

was nope every Alzheimer trial another

mistake every house on a trial that

targeted the plaques failed whether

you’re trying to turn off the spigot

turn off the amyloid production that’s

the brain overflowing with amyloid in

the middle or you tried to clear the my

doubt of the brain every attempt to do

so no improvement in cognition in the

patient’s failure after failure and

again this led to argument CD amyloids

not the right thing and then we realized

something because we had great

breakthroughs in brain imaging if you

look up top what you’re seeing there is

every time blue goes to yellow and red

that’s showing where amyloid is in the

brain now we can image and actually see

the amyloid in your brain and get an

idea of when D amyloid occurs and what

we learned was pretty striking the

amyloids building up 10 to 20 years

before any symptoms of

mention 10 to 20 years so if you follow

that that slope all the way to the left

you see the beta-amyloid goes up and

then when it starts to flatten out

that’s when does dementia it’s already

done its job the amyloid is already

built up and started the disease and so

then we’re going in there after emily

has already done it and saying don’t

worry we’re going to lower your amyloid

well horses out of the barn it’s

equivalent to this scenario here this is

poor guys having a heart attack and the

doc is saying it’s okay you just need to

clone your cholesterol right you had to

do that 10-15 years ago when you knew he

was on his way to heart disease you

don’t wait till the patient has symptoms

imagine and this brings up a point

imagine if we waited till someone had

symptoms of cancer organ failure or

waited till someone had congestive heart

failure and a heart attack to say okay

now you have cancer now your fault

disease right we don’t do that as soon

as you have a small tumor neoplastic

cell we say this cancer we have to treat

it when you start to see high

cholesterol and plaque around the heart

you say you’re starting heart disease we

have to treat it and so on the same

thing in AIDS when you have HIV you

don’t wait for symptoms of AIDS to say

you have AIDS but an Alzheimer’s disease

we wait until you have symptoms to

diagnose and treat the disease it’s like

how do we do that how’d that happen and

every other disease of Aging we stop it

with early intervention early detection

but in Alzheimer’s we diagnosed only

when you already have the disease and

then we try to bring you back that was

the big mistake amyloid is a good target

but you have to hit it early unlike cars

is using cancer we don’t treat the cause

early enough we need to stop those

plaques 10 to 20 years before symptoms

we can use brain imaging and biomarkers

now if patients who in people who are

asymptomatic or very mild mild memory

problems start to see whether it is

amyloid in the brain and that’s when you

treat you don’t wait until the horses

are at the barn and I think this gives

us great hope now that if we can

convince the FDA that this is the way

forward and there are many safe drugs on

the horizon we’re making them others are

making them safe drugs and therapies

that will bring that M

lay down we have to lower the bar a

little bit when we do trials we can’t

expect you’re going to bring somebody

cognitively back by hitting a pathology

to started the disease twenty years

before it’s good enough to lower the

amyloid there’s enough data now to say

come on let’s work together define

people early on who have amyloid

building up in their brain through

alarming levels and bring that amyloid

back down just like we do a cholesterol

heart disease that’s the turning point

right now like I said medical scientific

community Families FDA have to work

together to make this happen

now many people ask when I get to this

point well why do our brains make

amyloid why do we make it in the first

place and this is what I want to tell

you about a very exciting new hypothesis

that is arisen based on new data the

pathogen hypothesis and I don’t have a

lot of time to go into it but it appears

that our brains are not sterile living

in our brains are bacteria viruses like

herpes fungus like yeast especially as

we get older we’re getting more and more

little microbes and buggies living in

our brain and it turns out based on the

newest data that we have just published

that the plaques are actually there to

protect the brain when there’s an

infection even a low-grade infection the

amyloid plaques form around the herpes

or around the yeast of bacteria to trap

it and keep it away from the nerve cells

it’s trying to do a good job but then if

there’s too many of those plaques they

trigger the tangles in the rest of the

disease so this says that not only

tackle the amyloid early on but if we

can find out what types of microbes are

invading the brain we can hit those

early on as well

antivirals antibacterials etc the bottom

panel shows a herpes virus and then in

just 30 minutes or 2 hours you can see

amyloid plaque completely enveloping

that virus and that’s in in a mouse

brain or in the Alzheimer’s in the dish

so that says that we also have to be

careful when we hit amyloid with drugs

we don’t want to wipe it out we just

want to turn it down this in when this

happens I just want to show this one

slide that little red guy in the middle

you see the red guy in the middle he’s

eating that green strain coming out of

the green blob the green blob is a

nerves

and that green string is its axon it

goes to a synapse and what happens is

when you get this attack of amyloid and

bacteria in the brain those little guys

come microglial go crazy and eat nerve

cells

that’s called inflammation this is what

you have to stop in patients who have

the disease right now we have to stop

the amyloid plaques and tangles before

you even get there so now we have some

idea what to do with the right patient

right drug right time and then the end

what’s going to beat this disease as

early prediction based on family history

early detection with imaging of

biomarkers and early interventions not

that pathology before there are symptoms

just like we do for cancer heart disease

diabetes and we’re going to have to do

this all with a cocktail we’re going to

need to hit the plaques the tangos the

inflammation all of it I work closely

with the cure Alzheimer’s fund working

on all of these aspects and I think

we’re making great progress and I think

if we work together we’re going to beat

this disease I’ve actually never been up

more optimistic that we’re going to beat

this disease if we just take that out of

this in front of us and do the right

thing now and all work together to make

it happen now on the side until we have

those drugs what can you do I like to

use the acronym sleds sleds not that

you’re going to slide down but but get

eight hours of sleep learn so come to

Ted exercise at least 8000 steps per day

diet Mediterranean is the best omega-3

is very important stress try to meditate

very very beneficial so remember sleds

and that’s what we can do until we have

the right drugs now as I end on the side

I’m a musician I play often with with

Joe Perry of Aerosmith and I’ve played

in the last hours with the album this is

a Joe Perry on the Jay Leno Show looking

very suave and like a rock star and

that’s me in the back on the keyboards

saying what the heck am I doing here I’m

a geneticist but it’s but this what is

fun I also started a music app called

spark that it’s a music therapy app for

Alzheimer’s patients so I’d like to keep

music in my life and speaking of that at

this time I would like to welcome to the

thank you very much I have a strong

connection with Alzheimer’s both of my

grandmother’s passed away with forms of

the disease and my paternal grandmother

was diagnosed with early onset

Alzheimer’s in her late 40s so it’s

always been a very scary part of my life

so I was very very happy and excited to

connect with Rudy who I literally

cornered at the TV studio where we met

and demanded to learn as much about his

research as I possibly could not through

our connection with music and

Alzheimer’s we did want to write an

anthem of hope to raise awareness and

the song is called remember me we wanted

to write remember me from the

perspective of someone with Alzheimer’s

so that other people could relate to how

terrifying it is to live with this

disease and how crucial it is that we

find a cure by donating proceeds from

the sale of the song to Alzheimer’s

research we were able to take action a

step further with the help of cure

Alzheimer’s fund by producing a music

video and visual art piece for remember

me that very poignant ly portrays the

struggle of living with Alzheimer’s

through dance and music now at the time

I was playing the phantom of phantom of

the opera’ national tour so I was able

to implore my very talented cast and

crew mates who had a connection with the

disease to donate their time to the

cause as well here you can see us on set

creating the video our dancer our makeup

artist our hair department my wife who

directed Laura everyone donated their

time to bring this story to life here

are some still slides from the video you

can see a young woman in white whose

vibrant before the middle side which is

when she starts to show symptoms to the

upper slide when she’s fully lost in the

disease now what happened next is truly

remarkable when we posted our little

passion project on Facebook and YouTube

it was sharing and being viewed at such

a rapid pace that the live view counter

could not keep up people were sharing

the

video with their own remember me stories

about their families their connection to

the disease and a worldwide conversation

started you can see some of the the

press and some of the people sharing

their pictures of their loved ones with

the hashtag remember me right there

in short remember me struck a chord an

emotional chord with the community it

became a coping mechanism for families

and it really did become an anthem of

hope it was very very very powerful to

see so now we would love to perform

remember me for you now for all the

families dealing with this disease and

remind them that they will never be

I need someone to hold – hold on for me

– what I can’t seem to hold on to the

life we used to live is slipping through

my fingertips like a thread that’s

I suppose then nothing’s worth getting

when I can’t find the words that I’m

trying to speak when I don’t know the

face in the mirror

I see when I feel I’m forgotten and lost

I know they’ll come a day when I have

gone away and the memory of me will

faint but darling think of me and who I

used to be and I’ll be right there with

I hope I’m one thing worth not

forgetting tell me that you’ll never let

when I can’t find the words that I’m

trying to speak when I don’t know the

face in the mirror

I see when I feel forgotten and lost in

this world

I hope I’m one thing worth not

forgetting tell me that you’ll never let

me go when I can’t find the words that

I’m trying to speak when I don’t know

the face in the mirror I see when I feel

that I’ve lost and lo in this world won’t you please
