Erotomania after aneurysmal subarachnoid hemorrhage: case report and literature review.

A woman developed the delusional syndrome of erotomania 4 years after subarachnoid hemorrhage from a ruptured basilar artery aneurysm. The authors review the literature on erotomania in association with neurologic and medical conditions. Although no cause-and-effect relationship can be established between the neurologic event and erotomania in this patient, the possible neuropsychiatric correlates of this syndrome highlight the need for careful attention to neurologic and medical factors in future cases. Available information suggests that diffuse brain dysfunction may contribute to erotomania, perhaps by interfering with the operations of cerebral regions subserving complex emotional function.
