| Disorder of the basal ganglia involving the dopaminergic nigrostriatal pathway which produces a characteristic tremor, rigidity, and bradykinesia. |
|
|
| Inherited as an autosomal dominant trait resulting in a severe degeneration of the basal ganglia particularly the caudate and putamen nuclei, and the frontal cerebral cortex. Progressive intellectual dysfunction and abnormal movement are common. |
|
|
| A dysimmune disorder involving the degeneration of the CNS myelin resulting in plaque formation and progressive brain dysfunction resulting frequently in vision disorders, muscle weakness, numbness, ataxia, hypotonia - all dependent upon where in the brain the inflammation and plaque formation occurs. |
|
|
| Potentially a genetic disorder, this disorder results in the progressive lower and upper motor neuron degeneration resulting in progressive weakness, paresis, and muscle atrophy. |
|
|
| A humoral & cell-mediated immunologic reaction of the peripheral nerve myelin that produces demyelination and inflammation of the axons. Progressive ascending paresis/paralysis of occurs. If the nerve cell body survives, regeneration and restoration of motor activity occurs. |
|
|
| A chronic autoimmune disease of the neuromuscular junction where antibodies are produced to block acetylcholine receptor sites resulting in severe muscle fatigue and can lead to quadriparesis or quadriplegia. |
