Do miagranes headaches cause bleeds to the head had a mri&ct 5 months ago everything was normal i'm 20 is this true miagranes cause bleeds to the brain?

Vascular: Most migraines are vascular in nature. Constriction and/or spasm of vessels is the cause, not bleeds. There are medications yo take that can help, especially if taken inthe prodromal.Or early phase.

Very uncommon: Migraine headaches can be associated with areas of decreased brain blood flow. Rarely this can cause a stroke. Any stroke can have areas of bleeding but this scenario is very uncommon. Most non-trauma bleeding in the brain is caused by untreated high blood pressure or rupture of small aneurysms.
