Types of Stroke
Types list: The list of types of Stroke mentioned in various sources includes:
- Ischemic stroke - from reduced blood flow to a brain area.
- Hemorrhagic stroke - from bleeding in the brain.
- Right hemisphere stroke - a right brain stroke affecting the left side of the body.
- Left hemisphere stroke - a left brain stroke affecting the right side of the body.
- Cerebellar stroke - a stroke occurring in the cerebellum
- Brain stem stroke - occurring in the brain stem.
Types discussion: There are two types of stroke:
Ischemic stroke, the most common type of stroke. This type of stroke happens when there is a sudden lack of blood flow to some part of the brain, usually due to a blood clot blocking an artery or blood vessel. Often the artery is already clogged with fatty deposits (atherosclerosis).
Hemorrhagic stroke. Bleeding in the brain from a broken or leaking blood vessel causes this type of stroke. A hemorrhagic stroke may be due to an aneurysm—a thin or weak spot in an artery called that balloons out and can burst.
Either type of stroke can cause brain cells to die. This brain damage may cause a person to lose control of certain functions, such as speech, movement, and memory. Like a heart attack, a stroke is an emergency and should be treated as quickly as possible. 1
There are three major types of stroke:
Diagnosis and Treatment
A stroke requires immediate medical care. If you think you are
having a stroke, call 911. Research shows that treatment during the
first few hours after stroke symptoms appear can be important for
the best possible recovery. An emergency doctor or a neurologist (a
doctor who diagnoses and treats disorders of the brain and nervous
system) will provide emergency treatment. Then a family doctor,
internist, or geriatrician can step in and provide continuing
Doctors make an early diagnosis by studying symptoms, reviewing the patient's medical history, and performing tests such as a computerized tomography (CT) scan-a 3-dimensional x-ray of the brain.
What You Can do to Prevent a Stroke
A stroke is a single, damaging attack, but the conditions or risk
factors that lead to a stroke, such as high blood pressure, smoking,
heart disease, and diabetes develop over many years. The National
Institute of Neurological Disorders and Stroke (NINDS), part of the
National Institutes of Health, has developed a worksheet to help you
estimate your stroke risk. For a copy of Brain Basics: Preventing
Stroke, contact the NINDS information office listed
You can reduce your stroke risk by taking the following steps:
- Control your blood pressure. Have your blood pressure checked often, and, if it is high, follow your doctor's advice on how to lower it. Treating high blood pressure reduces the risk for both stroke and heart disease.
