Migraine link to Parkinson’s

Given that previous studies have associated movement disorders with individuals who suffer from migraine, researchers involved with a large cohort study in Iceland examined the association in participants over 25 years.

Among 5620 people aged 33–65 at baseline, about 1000 had headaches, 430 had migraine with aura and 238 had migraine with no aura.

Parkinsonian symptoms were more common in participants with mid-life headache compared to those with no headache, with participants experiencing migraine with aura having more than three times the likelihood of symptoms.
