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.

Background: Familial hemiplegic migraine (FHM) types 1-3 are associated with protein-altering genetic variants in , and , respectively. These genes have also been linked to epilepsy. Previous studies primarily focused on phenotypes, examining genetic variants in individuals with characteristic FHM symptoms.

A male in his 20s presented with episodic headache and subsequently developed episodic unilateral weakness, dysphasia and encephalopathy. These paroxysmal episodes persisted over time with the development of background cognitive impairment and neuropsychiatric symptoms. MRI surveillance demonstrated progressive T2 hyperintensity with focal cortical oedema correlating to symptoms observed during clinical episodes.

Familial hemiplegic migraine type 2 results from pathogenic variants in the gene, which encodes for a catalytic subunit of sodium/potassium ATPase. This extremely rare autosomal dominant disorder manifests with a spectrum of symptoms, most commonly pure hemiplegic phenotype, epilepsy, and/or intellectual disability. In this study, we detail the clinical features and genetic analysis of nine patients from a large family spanning four generations, with all carrying a previously unreported likely pathogenic variant, p.
