寛解期の双極性感情障害における脳MRI所見を伴わないゲシュヴィント症候群：症例報告

Geschwind Syndrome (GS) comprises a constellation of behavioural traits traditionally associated with temporal lobe epilepsy. These include hyper-religiosity, hypergraphia, altered sexuality, and circumstantial thought processes. Increasingly, GS features are also observed in other neuropsychiatric conditions. We present a 26-year-old female with bipolar affective disorder in remission who developed GS-like features such as hyper-religiosity, compulsive writing, and atypical romantic ideation, without evidence of seizures, abnormal EEG, or MRI findings. She showed limited response to aripiprazole and partial improvement with behavioural interventions. This case highlights the need for increased recognition of GS features in psychiatric populations, independent of structural or seizure-related pathology.
