Neuropsychologic phenotypes in familial hemiplegic migraine

Abstract

The 3 adolescents studied are from a large family in which the mother and 6 of 8 children are affected by FHM. The affected children are 4 males aged 33, 30, 15 and 13 years, and 2 females aged 30 and 10 years. Convulsions with fever were reported by the Michele RoccellaAbstract Familial hemiplegic migraine (FHM) is a rare autosomal dominant-type migraine with aura. Attacks are characterised by hemiparesis in addition to other aura and migraine symptoms. Few studies have examined the influence of FHM on cognitive functions. This study was aimed to investigate neuropsychological functions in 3 adolescent siblings suffering from FHM assessed six months after the last attack. No relevant deficits were found on a battery of multisectorial tests exploring cognitive functions. Sporadic FHM attack therefore seems not to affect cognition in these patients, at least far from the crises.
