So what is ALS?

Amyotrophic Lateral Sclerosis (ALS) affects the brain and the spinal cord. Motor neurons degenerate and die which makes it increasingly difficult to move muscles.

In the UK the illness is often referred to as motor neurone disease (MND), and the leading organisation is the Motor Neurone Disease Association.

In the US it is also known as Lou Gehrig’s Disease, named after the all-time great baseball player who was stricken with the illness in 1939.
