There is no cure for Ameyotrophic Lateral Sclerosis ALS. It is also known in the states as Lou Gherigs Disease (I think the spelling is correct). It comes under the heading of Motor Neurone Disease in the UK and other parts of the world. If you go to the Motor Neurone Disease Website, which is Motor Neurone Disease Association. MNDA. You will find all that is relevant to the condition. The most famous person ever with this condition is Professor Stephen Hawking, the british cosmotologist. He has lived for many years, but this is very, very rare. Life expectancy is usually a maximum of 5 years after diagnosis.
I know all this as I suffer from Kennedys Disease, this is similar to ALS, the proper name for it is Spinal Bulbar Muscular Atrophy. The difference is that it is slower. I have had it for 11 years. I was initially diagnosed with ALS in the beginning, but a DNA bloodtest illustrates the differences.
I wish you well as time goes by.
