Overview

Amyotrophic lateral sclerosis (ALS), also referred to as "Lou Gehrig's disease," is a progressive motor neuron disease which leads to problems with muscle control and movement.[1][2] There are various types of ALS, which are distinguished by their signs and symptoms and their cause.[2] Early symptoms may include muscle twitching, cramping, stiffness, or weakness, eventually followed by slurred speech and difficulty chewing or swallowing (dysphagia). As the disease progresses, individuals become weaker are are eventually wheelchair-dependent. Death often results from respiratory failure within 2 to 10 years after the onset of symptoms. Most affected individuals have a sporadic (not inherited) form of ALS; about 5-10% have a familial (inherited) form of the condition. Familial ALS may caused by mutations in any one of several genes and the pattern of inheritance varies depending on the gene involved.[2] Treatment is generally supportive.[3]
