Strokes and migraines share many of the same symptoms and are sometimes mistaken for each other. But does a migraine cause a stroke or vice versa? Research doesn't show that.
Studies do show that if you get a lot of migraines, you may have a higher chance of having a stroke later in life. But the risk is small.
Symptoms of an ischemic stroke (caused by a blood clot) vary from one person to another. But symptoms usually occur in the side of the body opposite from the side of the brain where the clot occurred. For example, a stroke in the right side of the brain affects the left side of the body.
Symptoms of a stroke may be so minor that they are ignored or
go unnoticed. Some people have symptoms that go away after a short time. This could be caused by a transient ischemic attack, or TIA. A TIA is a warning sign that a stroke may soon follow.
The symptoms of a hemorrhagic stroke (caused by bleeding in the brain) are usually the same as those from a blood clot. But you also may have other symptoms, such as:
Dizziness, seizures, or changes in mental state, such as
irritability, confusion, and possibly unconsciousness.
Hemorrhagic strokes usually occur during the daytime and during
physical activity. Symptoms of a hemorrhagic stroke usually begin very
suddenly (within seconds) and get worse over several hours.
