Disease details

What is ALS?

Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease or Motor Neurone Disease (MND) is a progressive, fatal neurological disease. The disorder belongs to a class of disorders known as motor neuron diseases.

ALS occurs when specific nerve cells in the brain and spinal cord that control voluntary movement gradually degenerate. The loss of these motor neurons causes the muscles under their control to weaken and waste away, leading to paralysis.

ALS manifests itself in different ways, depending on which muscles weaken first. Symptoms may include tripping and falling, loss of motor control in hands and arms, difficulty speaking, swallowing and/or breathing, persistent fatigue, and twitching and cramping, sometimes quite severely. ALS strikes in mid-life. Men are about one-and-a-half times more likely to have the disease as women.
