Neuromuscular disease
A neuromuscular disease is a disorder that affects the peripheral nervous system. The peripheral nervous system includes muscles, the nerve-muscle (neuromuscular) junction, peripheral nerves in the limbs, and the motor-nerve cells in the spinal cord.
Neuromuscular disorders
Neuromuscular disorders cover a wide range of conditions including neuropathies (either acquired or inherited), muscular dystrophies, amyotrophic lateral sclerosis (ALS), spinal muscular atrophy (SMA), as well as a range of very rare muscle disorders. There are many causes of progressive muscle weakness, which can strike any time from infancy through adulthood. Neurodegenerative diseases can affect different parts of the body in different ways. More than 40 different types of neuromuscular diseases have been identified
Most known
Definition - One of nine types of muscular dystrophy, a group of genetic, degenerative diseases primarily affecting voluntary muscles.
Cause - An absence of dystrophin, a protein that helps keep muscle cells intact.
Onset - Early childhood - about 2 to 6 years.
Symptoms - Generalized weakness and muscle wasting first affecting the muscles of the hips, pelvic area, thighs and shoulders. Calves are often enlarged.
Progression - DMD eventually affects all voluntary muscles, and the heart and breathing muscles. Survival is rare beyond the early 30s. A less severe variant is Becker muscular dystrophy.
Inheritance - X-linked recessive. DMD primarily affects boys, who inherit the disease through their mothers. Women can be carriers of DMD but usually exhibit no symptoms.
- Becker Muscular Dystrophy (BMD)
- Emery-Dreifuss Muscular Dystrophy (EDMD)
- Limb-Girdle Muscular Dystrophy (LGMD) 
- Facioscapulohumeral Muscular Dystrophy (FSH or FSHD) (Also known as Landouzy-Dejerine)
- Myotonic Muscular Dystrophy (MMD)
- Oculopharyngeal Muscular Dystrophy (OPMD)
- Distal Muscular Dystrophy (DD)
- Congenital Muscular Dystrophy (CMD)
