Dutch researchers have found a link between migraine headaches and the presence of brain lesions. CNN article here, and JAMA article here.
From CNN:
Using magnetic resonance images, the researchers found that for patients with both migraines and visual problems the risk of cerebral infarction -- tissue which has died due to lack of oxygen when a blood clot blocks an artery -- was 13 times higher than the group which had no migraines at all.
The problem increased with the frequency of migraine attacks.
Patients with migraine but no eye trouble had more than seven times the risk that would normally be expected. The problem occurred in the cerebellar region of the brain, which controls motor motions.
