ネパール農村部における憑依症候群：文化的、臨床的、および法医学的影響を検討するケーススタディ

Possession state is a disorder of consciousness with substitution of the personality, which is claimed to be a spirit, a deity, a dead person or some other power. In rural Nepal these experiences are normalised and Hindu communities often attribute psychological conditions to a supernatural cause. We report the case of a 30-year-old woman who presented with acute-onset symptoms characterised by episodes of altered consciousness, vocalisations suggestive of religious chants, and deity-associated behaviour, probably influenced by local suggestions of divine possession. Additional notable features included similar presentations among a family member and seeking help from traditional healers prior to psychiatric consultation. Medical examinations and investigations were normal. Specific cultural and religious manifestations posed challenges to clinical interpretation. The patient responded well to combined pharmacotherapy and supportive psychotherapy during her brief hospital stay, with cessation of possession episodes. This case report highlights the importance of cultural competence in Nepalese forensic psychiatric evaluations, particularly in the context of possession states, while examining the application of mental health legislation in traditional cultural settings.
