Understanding ALS

ALS, often referred to as, "Lou Gehrig's disease" is a rapidly progressive neurodegenerative disease. The name Amyotrophic Lateral Sclerosis, literally translated, breaks down as:

Amyotrophic means that muscles have lost their nourishment.
Lateral refers to the sides of the spinal cord.
Sclerosis means that the part of the spinal cord that is affected by the disease develops hardened, scarred tissue.

ALS damages the motor neurons (nerve cells that control voluntary muscle movement) in the brain and spinal cord. Messages from the brain's motor neurons are called the upper motor neurons, and are transmitted to the lower motor neurons in the spinal cord, and from there to specific muscles.

As the neurons degenerate, they no longer send the impulses necessary for movement to the muscle fibers. When the muscles lose their connections to the motor neurons, they waste away, which is known as atrophy. Eventually the brain can no longer start and control voluntary muscle movement.

As the disease progresses, problems with moving, swallowing, and speaking develop, along with loss of the ability to use arms or legs and walk or stand. In the later stages of the disease, patients may become totally paralyzed. The ability to see, smell, taste, and hear is not affected.

There are as many as 30,000 Americans suffering from ALS at any given time. In addition to legendary New York Yankee Lou Gehrig, ALS has tragically shortened the lives of such notables as Senator Jacob Javits, actor David Niven, jazz great Charles Mingus and pitcher Jim "Catfish" Hinter, among others. Stephen Hawking, world-famous physicist and author, has been living with ALS for 50 years, but most people die between 3 and 5 years after diagnosis.

While there are some therapies that can manage symptoms of ALS, there is no cure, which makes funding for research so critical.
