title: Anatomy and pathology of extrapyramidal diseases.
abstract: An overview of the anatomy of the basal ganglion system has been presented in conjunction with a brief outline of the diseases associated with it. The etiology of these degenerative diseases has been discussed, and the major morphologic changes at the macroscopic level are given. The probable pathologic and morphologic substrates of movement disorders have been suggested.
