系統的健忘を呈した1症例

A Case of Systematic Amnesia

　【抄録】　「私は17歳」と訴え，次いで夫との結婚生活が追想できない系統的健忘を呈した25歳の主婦の症例を報告した。かつて報告された系統的健忘や全生活史健忘と比較検討し，次のような知見を得た。（1）本例は生活歴で両親の離婚やいじめ，不良行為，退学などの精神葛藤を認め，性格で抑圧的，未成熟を示しており，これらは全生活史健忘の症例と類似していた。さらに，健忘の回復過程も全生活史健忘のそれとほぼ一致していた。それにもかかわらず，全生活史健忘に至らなかったのは，安心して帰れる家があったからと考えられる。（2）本例の健忘発生機序として，家出した後，17歳で家に戻らなかった後悔から，17歳よりの生活をやり直したい願望を抱き，そこで「私は17歳」と訴え，さらに父への依存的感情から夫を否定したため系統的健忘を示したと推測された。

　A Case report was made of a 25 year-old housewife showing symptoms of systematic amnesia. She had no recollection of her married life and maintained to her husband that she was 17 years old. A comparison of systematic amnesia with global amnesia reported the following findings. (1) This case showed conflicts similar to those experienced by people who have suffered from oppression, or from the divorce of parents, or from leaving school etc, or who have been delinquents. Her personality was oppressive and showed prematurity. Such features are similar to those found in cases of global amnesia. Moreover, the recovery process of amnesia also showed a similarity to that of global amnesia. In spite of these conditions, she hadn't fallen into global amnesia due to the existence of a home she could safely return to. (2) As a mechanism of these symptoms, she regretted that she could not return home after leaving at the age of 17. Because of this, she hoped to rocommence her life after the age of 17. This accounts for her conviction that she was still 17 years old. Moreover, her emotional dependence on her father forced her to deny the existence of her husband. Such factors were probably responsible for leading her into a state of systematic amnesia.
