A cerebrovascular event (stroke) is the term doctors use when a part of the brain dies because it goes without blood for too long. There are two main types of stroke: that caused by a blockage in a blood vessel in the brain, and that caused by bleeding in the brain or surrounding area.
The symptoms of a stroke may begin suddenly or develop over hours or days, depending upon the type of stroke. In both types of stroke, one or more areas of the brain can be damaged. Depending upon the area affected, a person may lose the ability to move one side of the body, the ability to speak, or a number of other functions. The damage from a stroke may be temporary or permanent. The long term outcome depends upon how much of the brain is damaged, how quickly treatment begins, and several other factors.
What Causes Stroke?
There are a number of risk factors for stroke; some of these factors increase the risk of one type of stroke (hemorrhagic or ischemic), while others increase the risk of both types.
Ischemic Stroke Risk Factors
- Age older than 40 years
- Heart disease
- High blood pressure
- High blood cholesterol levels
- Illegal drug use
- Recent childbirth
- Previous history of transient ischemic attack
- Inactive lifestyle and lack of exercise
- Current or past history of blood clots
Hemorrhagic Stroke Risk Factors
- High blood pressure
- Illegal drug use (especially cocaine)
- Use of warfarin or blood thinner medicines
What Ate The Symptoms Of Stroke?
Knowing the signs and symptoms of a stroke can be lifesaving. Classic stroke symptoms can be recalled with the acronym FAST. Each letter in the word stands for one of the things you should watch for:
Face — sudden weakness or droopiness of the face, or problems with vision
Arm — sudden weakness or numbness of one or both arms
Speech — difficulty speaking, slurred speech, or garbled speech
Time — time is very important in stroke treatment. The sooner the treatment begins, the better the chances are for recovery
Signs and symptoms of a stroke may be similar to other conditions; the only way to know for sure is to see an experienced doctor as soon as possible.
What Is The Treatment For Stroke?
The treatment for stroke depends upon the type of stroke, the time that has passed since the first symptom occurred, and the patient’s other medical problems.
