Having a stroke is one of the most frightening prospects of aging. Strokes can come on suddenly, stealing the use of an arm or the ability to speak. A stroke can be fatal or leave us permanently disabled.
About half of all strokes are caused by atherosclerosis -- the same process of narrowing and hardening of the arteries that causes heart attacks. Atherosclerosis progresses silently, without symptoms, putting our brains and our independence at risk.
Reducing the risk factors for atherosclerosis...
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.
