What Are The Signs Of A Stroke?
The warning signs of stroke are:
- Sudden weakness or numbness of the face, arm, and leg on one side of the body
- Sudden loss of vision or dimmed vision, particularly in one eye
- Loss of speech, or trouble talking or understanding speech
- Sudden, severe headaches with no apparent cause
- Unexplained dizziness, unsteadiness, or sudden falls, especially if accompanied by any of the previous symptoms
Most severe headaches are not a sign of stroke. Migraine, which can cause quite severe and sometimes alarming headaches, is very common and affects about one in five people.

What Do Different Parts Of The Brain Do?
The brain is a very complicated organ. Although it is a relatively small part of the body, it uses one-quarter of the blood supply.
When a person is right handed, the left side of the brain is dominant. About 90 percent of left-handed people have the right side of the brain dominant.
