When symptoms of amyotrophic lateral sclerosis (ALS), such as weakness and a loss of muscle mass, start in the limbs, doctors refer to the condition as limb onset ALS. ALS is a progressive condition ... Amyotrophic lateral sclerosis (ALS) affects the nerve cells in the brain and spinal cord that control muscle movement.

Understanding the Context

Different types of ALS cause symptoms to begin in a certain part of the body and ... Amyotrophic lateral sclerosis (a-my-o-TROE-fik LAT-ur-ul skluh-ROE-sis) is a nervous system disease that affects nerve cells in the brain and spinal cord. Also known as ALS, the disease leads to muscle weakness and gets worse over time. ALS, or amyotrophic lateral sclerosis, is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord.

Key Insights

There is no cure for ALS yet. Amyotrophic lateral sclerosis (ALS), formerly known as Lou Gehrig’s Disease, is a neurological disease that affects motor neurons—those nerve cells in the brain and spinal cord that control voluntary muscle movement. Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig's disease, is a rare terminal neurodegenerative disease defined by the progressive loss of both upper and lower motor neurons that normally control voluntary muscle contraction. Amyotrophic lateral sclerosis (ALS), also known as Motor Neuron Disease (MND), Lou Gehrig's Disease, and Charcot's disease, is a progressive neurodegenerative disease that causes the degeneration and eventual death of motor neurons in the brain and spinal cord.
