Neuromuscular disease refers to a group of disorders that affect the nerves controlling voluntary muscles. These conditions can lead to muscle weakness, wasting, and difficulties with movement. Common types include amyotrophic lateral sclerosis (ALS), muscular dystrophy, and myasthenia gravis. These diseases can result from genetic mutations, autoimmune responses, or other factors that disrupt the communication between nerves and muscles. Symptoms may vary widely, but they often include fatigue, cramps, and coordination problems. Early diagnosis and treatment are essential for managing symptoms and improving quality of life.
