Other extrapyramidal disease and abnormal movement disorders

Other degenerative diseases of the basal ganglia
- A rare neuroaxonal dystrophy, histologically characterized by axonal spheroids, iron deposition, lewy body (LB)-like intraneuronal inclusions and neurofibrillary tangles.
- spastic weakness of the muscles innervated by the cranial nerves, i.e., the muscle of the face, pharynx, and tongue, due to bilateral lesions of the corticospinal tract.
- A progressive neurological disorder characterized by ophthalmoplegia, dystonia, memory impairment, personality disorders, and dementia. Etiology is unknown.
