On Aug. 21, 2024, Contrary to previous research, a new study of female participants finds no link between migraine and the risk of developing Parkinson’s disease.

The study involved 39,312 female participants with an average age of 55 at the start of the study. A total of 7,321 of the participants reported current or past migraine at the start of the study. The participants were then followed for an average of 22 years. During that time, 685 people reported physician-diagnosed Parkinson’s disease. Of those, 128 were people who reported a history of migraine or active migraine, and 557 were people with no migraine. The study was published in the online issue of Neurology.
