Depending on what part of the brain was affected by a stroke, the way a person acts may be different from how he or she acted before the stroke.
A person who was very concerned about details before a stroke may become sloppy and care little about personal appearance after a stroke. Because these problems may be annoying, it is easy to think that there is an emotional or psychological problem. In some cases, that may be true. But also consider:
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.
