Amyotrophic Lateral Sclerosis
Amyotrophic Lateral
Sclerosis

ALS

Lou Gehrig’s Disease

what’s in a name ?
a
myo
trophic
lateral
sclerosis

“without”
“muscle”
“nourishment”
“side (of the spinal cord)”
“hardening” or “scarring”

So,

Amyotrophic means that the muscles in the body are losing nourishment.
When muscles lose nourshment, they become weaker and smaller.

Did you walk to school today? Eat lunch? Breathe? All
of these things become difficult when you have ALS.
Motor neurons
are nerve cells that control muscle movement
(They aren’t quite like trucks. They don’t move.)

WITHOUT ALS

WITH ALS

motor neurons

motor neurons

exist in the brain and spinal cord

start to break down, and eventually die

motor neurons
pass messages from the brain
to the muscles

If the motor neurons are dead, the brain
can’t send signals to the muscles

When the messages reach
the muscles, they tell the muscles

Because the motor neurons
are not sending the brain’s
messages to the muscles, the person

how to move

cannot move
who has ALS?
RICK FRIEDMAN / CORBIS

30,000

Americans have ALS at this very moment -

That’s almost enough people to fill Fenway Park during a game.

LOU GEHRIG

Lou Gehrig, a New York Yankees German-American baseball player, is
the a famous figure in history to have been diagnosed with ALS.l
One of the most common names for ALS, Lou Gehrig’s Disease,

1903-1941

Stephen Hawking is an English physicist at the University of Cambridge.
He was diagnosed at the age of 21, but lives today, at the age of 71.

1942-

Stephen Hawking
WHO
develops
als?

Most people who develop ALS are
between the ages of 40 and 70
Patients are expected to live 2-5 years longer after they are diagnosed.

however,
ALS occurs
throughout the

world

without racial

ethnic
socioeconomic

boundaries
so how do people get ALS ?
the bad news
No one is really sure.

the good news

Some people have ideas.

Some scientists from Johns Hopkins Universtiy say that ALS has a
lot to do with something called

neurotransmitters

neurotransmitters
are a lot like your iPhone, but
instead of sending iMessages to
friends, they send messages to
specific cells

just like text messages

too many

neurotransmitters is a bad thing.

)You want to have just the right amount(
how NEUROTRANSMITTERS work

1

An electrical signal
enters the

A
XON
NEUROTRANSMITTERS
are held inside

V E S IC L E S

2

The signal causes the

VESICLE
to release the

NEUROTRANSMITTERS
The other cell receives the

NEUROTRANSMITTERS
and the message

3
how NEUROTRANSMITTERS work
WITH ALS
The scientists think that
sometimes, in some
people, there are too many

glutamate

neurotransmitters

)

glutamate
is just one type of

(

NEUROTRANSMITTER

Remember?

too many

neurotransmitters is a bad thing.
=
Long

story

short
This causes a

chain effect

That

KILLS
motor neurons

And if
motor neurons
are dead, muscles

cannot
move

does this sound familiar ?
(Hint: check back to the second page!)
There is a lot that is still unknown about
ALS, and life with ALS can be hard. But
there’s hope.

Stephen Hawking
once said

“

I have had motor neuron disease for
practically all my adult life. Yet

it has not prevented me
from having a very attractive family
and being successful in my work...

I have been lucky
that my condition has progressed
more slowly than is often the case.
But it shows that

one need not
lose hope.
