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, determine if he or she is having a bleeding stroke or a stroke from a blood clot, and begin appropriate therapy within 3 hours.
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.
Certain therapies, such as repositioning and range-of-motion exercises, are intended to prevent complications related to stroke, like infections and bed sores. People should stay active within their physical limitations. Sometimes, urinary catheterization or bladder/bowel control programs may be necessary to control incontinence.
The person's safety must be considered. Some people with stroke appear to have no awareness of their surroundings on the affected side. Others show indifference or lack of judgment, which increases the need for safety precautions. For these people, friends and family members should repeatedly reinforce important information, like name, age, date, time, and where they live, to help the person stay oriented.
Caregivers may need to show the person pictures, repeatedly demonstrate how to perform tasks, or use other communication strategies, depending on the type and extent of the language problems.
In-home care, boarding homes, adult day care, or convalescent homes may be required to provide a safe environment, control aggressive or agitated behavior, and meet medical needs.
Behavior modification may be helpful for some people in controlling unacceptable or dangerous behaviors.
Family counseling may help in coping with the changes required for home care. Visiting nurses or aides, volunteer services, homemakers, adult protective services, and other community resources may be helpful.
Legal advice may be appropriate. Advance directives, power of attorney, and other legal actions may make it easier to make ethical decisions regarding the care of a person who has had a stroke.
Carotid endarterectomy (removal of plaque from the carotid arteries) may help prevent new strokes from occurring in people with large blockage in these important blood vessels.
