Muscle disorders cause different symptoms, including paralysis, weakness and pain, MedlinePlus notes. Each muscle disorder has symptoms that are common for the disease. In some cases, such as with muscular dystrophy, symptoms may appear at birth, notes the National Institute of Neurological Disorders and Stroke.

Muscular dystrophy is one muscle disorder that can be severe. There are nine forms of muscular dystrophy: Becker, congenital, Duchenne, distal, Emery-Dreifuss, myotonic, limb-girdle, facioscapulohumeral and oculopharyngeal, according to Johns Hopkins Medicine. Each type of muscular dystrophy has an age range of onset as well as symptoms, prognosis and life expectancy. The common factor for all muscular dystrophy forms is that they are progressive and lead to the muscle wasting away.

The treatments for muscular disorders depend on the disorder, states National Institute of Neurological Disorders and Stroke. Doctors use drug therapy, physical therapy, surgery, braces and immunosuppressants to treat some disorders. In other cases, no treatment is available except for supportive therapy and pain relief. The prognosis varies as well, with some patients having near normal life expectancies and few disabilities and others experiencing severe, progressive, possibly life-threatening disabilities.
