We report a 77-year-old Japanese man with pro-gressive gait disturbance. He was well until his 71 years of the age (1992), when he noted an onset of disturbance in his speech, which was followed by diffi-culty in using his left hand. He did not attempt to use his left hand afterwards. He started to fall down in the spring of 1994. He was admitted to our service on Oc-tober 6, 1994. Neurologic examination revealed an alert and oriented man. He showed limb-kinetic apraxia in his left hand with anosognosia for his apraxia. Vertical gaze was impaired. He walked in small steps. He had moderate axial and limb rigidity.
