Stroke Information - Cause, Prevention, Signs, Symptoms, Treatment and recovery of stroke
A stroke occurs when a blood clot or bleeding cuts off the blood supply, and
therefore the oxygen, to part of the brain. The affected area of the brain will
eventually die. The effect of a stroke depends on how much of the brain is
affected and where the clot or bleeding is. Different parts of the brain control
different functions, so a clot in the part of the brain that controls speech, for
example, will result in slurred or confused speech. Often the signs will be
confined to one side of the body.
Effects of Stroke
If the bleeding or clot is in one of the larger blood vessels supplying a large area of the brain, then the stroke will often be immediately fatal. However, many people do survive such strokes, some making a full recovery, while others may need extensive periods of rehabilitation and support to manage stroke-related problems such as reduced mobility.
Signs and Symptoms of Stroke
Any combination of the following may be present. In minor strokes, the signs and symptoms may be very limited.
- History - the sufferer may have a history of smaller strokes over previous years, or may have been feelingunwell for some days with no known cause .
- Headache.
- Blurred vision, partial loss of sight or seeing flashing lights.
- Confusion and disorientation, often mistaken for drunkenness.
- Signs of paralysis or weakness, often only down one side of the body.
- Difficulty speaking; drooping mouth.
- Dribbling from one side of the mouth.
- Loss of consciousness (this can be gradual or sudden).
- Sometimes the pulse will be full and throbbing, the person's breathing noisy and the skin flushed.
Stroke Treatment
Monitor airway and breathing and be prepared to resuscitate if necessary. Place the person in the recovery position if she becomes unconscious. If she is conscious, help her to lie down with the head and shoulders slightly raised. Provide support and reassurance. The person will often be disorientated and may be speaking nonsense if the speech centre is affected.
Equally, she may hear what you are saying but not understand it. Speak in a reassuring tone with confidence. Call an ambulance. Wipe any dribbling away from the side of the face and be prepared for the person to be sick.
Stroke Recovery and Prevention
Hospital treatments for a stroke have developed tremendously in recent years but their effectiveness relies on early recognition and diagnosis of strokes. Friendsand relatives of older people, or those at higher riskof stroke, such as people with high blood pressure, should be aware of the signs and symptoms of stroke listed in the box.
Confused behaviour combined with headaches or vision problems are early warning signs, and if noticed the sufferer should be encouraged to visit a doctor. In addition, there is a number of simple home tests that may help identify a minor stroke:
- Ask the person to smile. Minor strokes often cause minor paralysis. Look for an uneven or drooping smile.
- Ask the person to hold both arms out in front of her. Minor strokes often cause minor weakness on one side. There may be damage or loss of sensation on one side. Look for one arm drooping or shaking.
- If you suspect signs of a stroke in a person who otherwise seems well, seek medical advice quickly.
