Neuropsychological functioning in migraine: clinical and research implications

Area of Science:

• Neuroscience
• Cognitive Psychology
• Neurology

Background:

• Migraine is a common neurological disorder.
• Neuropsychological performance in migraineurs is a subject of ongoing research.
• Understanding cognitive function in migraine is crucial for patient care.

Purpose of the Study:

• To systematically review and synthesize existing research on neuropsychological performance in individuals with migraine.
• To organize findings by neuropsychological construct and analyze effect sizes.
• To identify factors influencing cognitive performance in migraine.

Main Methods:

• Literature review of studies examining neuropsychological performance in migraine.
• Organization of findings based on neuropsychological domains (e.g., memory, attention, processing speed).
• Analysis of results using effect size conventions and consideration of moderating factors.

Main Results:

• Weak evidence suggests deficits in processing speed, attention, and memory in migraineurs compared to healthy controls.
• Mixed results were found for visual memory, motor skills, and visuospatial abilities.
• Limited evidence indicates migraine is not a significant risk factor for cognitive decline or Alzheimer's disease over time.

Conclusions:

• Cognitive dysfunction may be present in a subset of migraineurs, potentially those with severe illness or neurological involvement.
• Comorbidities and treatment-seeking variables may contribute to inconsistent findings.
• Neuropsychological evaluations for migraine patients should consider broader medical and psychological factors.
