頭部外傷後の全生活史健忘

A Case of Post-Traumatic Autobiographic Amnesia

　頭部外傷後に全生活史健忘を呈した23歳女性を報告した。全生活史健忘は従来精神科領域の疾患として知られているが，器質的な脳疾患でも稀に認められることがあり，鑑別診断として念頭におく必要がある。

A 23-year-old woman who was in the ninth month of pregnancy suffered a head injury by falling from the stairs. She regained consciousness in the ambulance car, however, could not recall anything about herself. The morning after, her neurological examination disclosed no abnormal findings. She was alert, spatially oriented, but unable to recall any personal information about herself, her work and family contexts. The results of WAIS-R and WMS were within normal range, and she showed a dissociation between a detailed knowledge of public events and famous people and a complete loss of autobiographic information.
