Neuromuscular diseases are a group of conditions that affect the muscles and nerves controlling them. These diseases can cause muscle weakness, paralysis, pain, impaired tendon reflexes, increased sensitivity to touch, and other muscle and nerve impairments. Common neuromuscular diseases include myasthenia gravis, muscular dystrophy, amyotrophic lateral sclerosis (ALS), and peripheral neuropathy. Myasthenia gravis is an autoimmune disease that affects the neuromuscular junction controlling muscle contraction. In this disease, the immune system fails to recognize the body's muscles, leading to muscle weakness. Muscular dystrophy is a genetic disorder that causes gradual weakening of the muscles. This is caused by defects or damage in the genes that control muscle development. ALS is a progressive motor neuron disease caused by degeneration of the nerve cells responsible for muscle control. In ALS, cells in the brain and spinal cord that control muscle movement start to die, leading to muscles wasting away. Peripheral neuropathy is a disorder that affects the peripheral nerves which are responsible for sending messages between the brain and other parts of the body. Symptoms can include weakness and numbness of the affected areas and can lead to difficulties in walking or coordinating movement. To diagnose neuromuscular diseases, medical professionals may conduct a physical examination and run a series of tests. These tests can include a nerve conduction study, electromyography (EMG), and muscle biopsies. Treatment for neuromuscular diseases is individualized based on the patient's symptoms and the severity of the condition.
