文献概要

Ⅰ．はじめに

　Transient ischemic attack（TIA）およびreversible ischemic neurologic deficit（RIND）とは筋力低下，感覚低下，視力低下といった脳機能の局所的な神経脱落症状の一時的な出現を意味し，不随意運動のような症状は通常TIAやRINDとはみなされない^2,3,8)．一方，hemichoreaやhemiballismのような永続的不随意運動は主に脳血管障害によって引き起こされることはよく知られており視床下核およびその関連経路の障害が主な原因病巣とされる^6,15,17)が，不随意運動が一過性である場合は比較的稀である^{2,7,14,18,19)}．今回われわれは，hemiballismを呈したRINDの稀な症例を経験したので文献的考察を加え報告する．
