We report a 68-year-old man with progressive speech disturbance and dementia. He was well until 1995, when he noted an onset of difficulty in speech. He was able to name simple objects and understand language, however, he showed great difficulty in spon-taneous speech. In 1998, he visited our service. He was alert and oriented, but he showed moderate de-gree of dementia. He did not appear to have aphasia but he showed marked dysarthria and slurred speech. He showed limb-kinetic apraxia in his right hand. He showed moderate restriction in his vertical gaze, masked face, and dysphagia.
