Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig’s disease, is a fatal neurodegenerative disease that affects the motor neurons in the brain, brain stem, and spinal cord. People with ALS/MND lose the ability to initiate and control voluntary muscle movement, but their mind remains sharp. The average life expectancy is 3-5 years from time of diagnosis. The cause of ALS/MND remains unknown and there are no effective treatments available for people living with the disease.
