What is ALS?
A better understanding of ALS, the disease process, is crucial to our efforts to develop effective therapies and a cure.
ALS, also known as Lou Gehrig’s disease and motor neuron disease, is a fatal neurodegenerative disease that affects adults of all ages. It is closely related to Alzheimer’s, Parkinson’s, and Huntington’s.
ALS targets large brain cells residing in the brain and along the spinal cord called motor neurons. In ALS, as motor neurons get sick and die, a person progressively loses the ability to move: to walk, speak, swallow, and breathe. ALS is usually fatal within 2-5 years of diagnosis.
