Neuromuscular Disorders
Neuromuscular disorders affect the nerves that control voluntary muscles and the nerves that communicate sensory information back to the brain. Nerve cells send and receive electrical messages to and from the body to help control voluntary muscles. When the neurons become unhealthy or die, communication between the nervous system and muscles breaks down. As a result, muscles weaken and waste away. These disorders include: amyotrophic lateral sclerosis (ALS), Charcot-Marie-Tooth disease, multiple sclerosis, muscular dystrophy, myasthenia gravis, myopathy, myositis, including polymyositis and dermatomyositis, peripheral neuropathy and spinal muscular atrophy.
