Hippocampal pathology in two mentally ill paraphiliacs.
Paraphilias or disorders of sexual behavior have markedly increased in prevalence during the last decade. Until now no published neuropathological studies on paraphilia have appeared in the medical literature. A computerized search was done on all available medical and autopsy records of a large urban hospital (St. Elizabeths Hospital, Washington, DC) for any mention of deviant sexual behavior. Cases were then reviewed for presence of a history consistent with DSM-IV diagnoses of paraphilia. Two such cases were identified. Neuropathological examination in both cases revealed simple cell atrophy of pyramidal cells confined to different hippocampal subfields. Reactive astrocytosis was present in the outer strata of the affected regions. The pathological changes in the hippocampus resemble those reported after persistent stress or long-term chronic glucocorticoid administration. The accompanying astrocytosis indicates a reactive, ongoing process. The findings suggest new therapeutic interventions in the treatment of paraphilia.
