[Palilalia associated with progressive supranuclear palsy].
Two cases of progressive supranuclear palsy (PSP) with palilalia were presented. Case 1: A 64-year-old woman was in good health until age 62 when she noted clumsiness in walking. Subsequently, forgetfulness, abrupt falls and difficulty in swallowing developed. At the age of 63, she tended to repeat same words in conversation. On admission, neurological examination revealed mental deterioration (Hasegawa's scale 19), unsteady emotional state, supranuclear vertical gaze palsy, pseudobulbar palsy, nuchal dystonia, pyramidal tract signs and extrapyramidal signs. Although spontaneous speech production was reduced, she could answer to questions with compulsive repetition of a phrase or word. She always repeated twice or three times without stuttering, logoclonus or "palilalie aphone". Case 2: A 68-year-old, right-handed woman noted double vision since about one year ago. Subsequently, she developed slowness of voluntary movement, forgetfulness and difficulty in walking. Neurological examination showed similar signs as Case 1. She was not palilaic on examination, however we found the description of her palilalia on nurse's working records. Palilalia was not present so constantly as Case 1, but continued for about a year. We suppose that palilalia is not a rare phenomenon in PSP. Although the pathogenesis of palilalia is unknown at present, we speculate the combination of extrapyramidal sign, pseudobulbar palsy and dementia may most contribute the pathogenesis of palilalia on PSP.
