Stroke

Alternative Names:

Cerebrovascular disease; CVA; Cerebral infarction; Cerebral hemorrhage

Treatment:

A stroke is a medical emergency. Physicians have begun to call it a "brain attack" to stress that getting treatment immediately can save lives and reduce disability. Treatment varies, depending on the severity and cause of the stroke. For virtually all strokes, hospitalization is required, possibly including intensive care and life support.

The goal is to get the person to the emergency room immediately, determine if he or she is having a bleeding stroke or a stroke from a blood clot, and start therapy -- all within 3 hours of when the stroke began.

IMMEDIATE TREATMENT

Thrombolytic medicine, like tPA, breaks up blood clots and can restore blood flow to the damaged area. People who receive this medicine are more likely to have less long-term impairment. However, there are strict criteria for who can receive thrombolytics. The most important is that the person be evaluated and treated by a specialized stroke team within 3 hours of when the symptoms start. If the stroke is caused by bleeding rather than clotting, this treatment can make the damage worse -- so care is needed to diagnose the cause before giving treatment.

In other circumstances, blood thinners such as heparin and coumadin are used to treat strokes. Aspirin and other anti-platelet agents may be used as well.

Other medications may be needed to control associated symptoms. Analgesics (pain killers) may be needed to control severe headache. Anti-hypertensive medication may be needed to control high blood pressure.

Nutrients and fluids may be necessary, especially if the person has swallowing difficulties. The nutrients and fluids may be given through an intravenous tube (IV) or a feeding tube in the stomach (gastrostomy tube). Swallowing difficulties may be temporary or permanent.

For hemorrhagic stroke, surgery is often required to remove pooled blood from the brain and to repair damaged blood vessels.

Life support and coma treatment are performed as needed.

LONG-TERM TREATMENT

The goal of long-term treatment is to recover as much function as possible and prevent future strokes. Depending on the symptoms, rehabilitation includes speech therapy, occupational therapy, and physical therapy. The recovery time differs from person to person.
