Psychotic aura symptoms in familial hemiplegic migraine type 2 (ATP1A2)

Abstract

Abstract INTRODUCTION: Neuropsychological symptoms are rare in familial hemiplegic migraine (FHM). There are no reports of psychotic symptoms in FHM type 2 (ATP1A2). We examined a family with a FHM phenotype due to a M731T mutation in ATP1A2. A 10-year follow-up allowed us to observe complex auras, including psychotic symptoms in two siblings.

CASE REPORT: Male, 48 years old, with an aura that included complex illusions with a feeling of time travelling, coincident with other aura features. The aura was regarded as mystical by the patient. Female, 38 years old, with a complex migraine aura, during which she believed she had the ability to time travel and was being followed by lobbyists who wanted to steal this ability from her.

DISCUSSION: FHM type 2 must be included in the list of differential diagnoses of acute psychosis in patients with a previous history of migraine aura.
