Familial Hemiplegic Migraines and Baseline Neuropsychological Testing: A Case Report.

Objective: To explore the neuropsychological correlates and implications of familial hemiplegic migraines (FHMs). Background: FMH is a rare, autosomal dominant subtype of migraine that only occurs in 0.01% of the population. Little is known about the neuropsychological impact of FHMs; however, cognitive impairment associated with cerebellar syndrome has been identified in some cases. Method: A single case study involving a 24‐year‐old male who recently endured an atypical, prolonged FHM episode. Results: The patient's overall neuropsychological functioning was intact with low average semantic fluency and processing speed, and mild indications of executive dysfunction. Conclusion: Baseline and serial neuropsychological testing in individuals with FHM may help identify the potential progression and course of cognitive impairment associated with this condition.
