On a Case of Senile Dementia with Echopalilalia

Abstract

    Long-interval palilalia (LIP) and echopalilalia observed in a case of senile dementia (Pick's disease suspected) was reported. Echolalia (repetition of examiner's question) and LIP (repetition of the patient's own answer with a long interval) were independent to each other in the initial stage of our observation. Several months later both speech symptoms were combined to the form of echopalilalia, in which the patient repeated several times only a part of the question with short interval. The implications of the symptomatological change were discussed from the clinical point of view.
