Though the exact cause of ALS is unknown, genetic and environmental factors are thought to be of roughly equal importance. 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. This eventually affects chewing, swallowing, speaking and breathing. Amyotrophic lateral sclerosis (ALS) is a disease of unknown cause in which there is a loss of motor neurons (nerve cells controlling muscles) in the anterior horns of the spinal cord and the motor nuclei of the lower brain stem.

The disorder is named for its underlying pathophysiology, with “amyotrophy” referring to the atrophy of muscle fibers, which are denervated as their corresponding anterior horn cells degenerate. ALS Association. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that signal and control the muscles are located. They are also at higher risk of getting food, liquids or saliva into the lungs, which can cause pneumonia. Signs and symptoms might include: ALS often starts in the hands, feet or limbs, and then spreads to other parts of your body. Amyotrophic lateral sclerosis (ALS) is a group of rare neurological diseases that mainly involve the nerve cells (neurons) responsible for controlling voluntary muscle movement.

However, all people with ALS will experience progressive muscle weakness and paralysis. As the disease progresses, ALS causes complications, such as: Over time, ALS paralyzes the muscles you use to breathe. Lou Gehrig's disease definition is - amyotrophic lateral sclerosis. As this area degenerates, it leads to scarring or hardening ("sclerosis") in the region. ALS often begins with muscle twitching and weakness in a limb, or slurred speech.
