This disease is a neuro-degenerative disease where the victim gradually loses voluntary motor function and cognitive abilities. After the diagnosis, victims typically require full-time care within 10 years or less due to complete loss of function. Most become either wheelchair-bound or bedridden. Many develop dementia, or depression, or psychosis, or all of the above. In the United States, 1 in every 30,000 people have the disease, but that number does not include the people who will eventually develop symptoms, but don't even know it. It is a very serious condition and it is important to understand the epidemiology of this disease as well as how to recognize symptoms early.
