Amyotrophic Lateral Sclerosis

What Causes ALS?

Doctors don't know what causes this disorder at the moment.

Symptoms of the Disorder

The first sign of ALS is often weakness in one leg, one hand, the face, or the tongue. The weakness slowly spreads to both arms and both legs. This happens because as the motor neurons slowly die, they stop sending signals to the muscles. So the muscles don't have anything telling them to move. Over time, with no signals from the motor neurons telling the muscles to move, the muscles get weaker and smaller.

Treatments and Survival/Death rates

Survival: 0% Death: 100% Is it treatable not right now because if it was treatable than there would actually be people surviving from the disease.

Current Research Q's and A's

Q: Is it being research right now?

A: Yes it is.

Q: What kind of research?

A: Scientists are seeking to understand the mechanisms that selectively trigger motor neurons to degenerate in ALS, and to find effective approaches to halt the processes leading to cell death.
