Cognitive dysfunction and migraine
Cognitive dysfunction has recently gained attention as a significant
problem among migraine sufferers. All of the clinical studies show poor
cognitive performance during migraine attacks, though, the interictal
data are conflicting. Migraineurs show impaired cognitive function
interictally in most of the clinic-based studies. Population-based
studies did not reveal a difference in cognitive functions between
migraineurs and controls. The specific cognitive domains involved are
information processing speed, basic attention, executive functions,
verbal and non-verbal memory and verbal skills. Neurophysiological,
imaging and pharmacological studies support clinical symptoms of
cognitive impairment in migraine. Longitudinal studies do not suggest
progressive cognitive decline over time in migraine patients. Preventive
medications and comorbid disorders such as depression and anxiety can
impact cognitive function, but cannot fully explain the cognitive
impairment in migraine. In contrast to migraine, tension type or cluster
headache are not associated with cognitive impairment, at least during
headache-free periods
