Definition : A degenerative disease of the central nervous system characterized by balance difficulties;
ocular motility disorders (supranuclear ophthalmoplegia); dysarthria; swallowing difficulties;
and axial dystonia. Onset is usually in the fifth decade and disease progression occurs
over several years. Pathologic findings include neurofibrillary degeneration and neuronal
loss in the dorsal mesencephalon; subthalamic nucleus; red nucleus; pallidum; dentate
