How migraines impact cognitive function: findings from the Baltimore ECA.

Area of Science:

• Neurology
• Cognitive Science
• Epidemiology

Background:

• Migraine headaches are a common neurological disorder.
• Cognitive functioning can be affected by various health conditions.
• Understanding the long-term impact of migraine on cognition is crucial.

Purpose of the Study:

• To investigate the cross-sectional and longitudinal relationship between migraine headaches and cognitive functioning.
• To determine if migraineurs experience different cognitive trajectories compared to non-migraineurs.

Main Methods:

• Utilized data from the Baltimore Epidemiologic Catchment Area Study (Waves III and IV).
• Diagnosed migraine headaches using modified International Headache Society criteria.
• Assessed cognitive function using immediate/delayed recall and the Mini-Mental State Examination (MMSE).
• Employed generalized estimating equations for longitudinal analysis.

Main Results:

• Migraineurs demonstrated lower baseline memory scores but experienced less cognitive decline over 12 years than non-migraineurs.
• Migraineurs with aura showed significantly less decline in immediate and delayed recall.
• The protective effect of migraine with aura on MMSE scores was observed only in individuals over 50 years old.

Conclusions:

• Migraineurs, particularly those with aura, exhibit a slower rate of cognitive decline over time.
• The observed cognitive benefits of migraine with aura on the MMSE are specific to individuals older than 50.
• Migraine with aura may have a neuroprotective effect on cognitive aging in certain populations.
