Stroke symptoms usually develop suddenly, and there is no warning before they appear. Symptoms include loss of control of certain muscles and difficulty speaking, swallowing, or using language.

Once a stroke victim develops a neurological condition, he or she will need assistance with daily activities, such as eating and walking. A speech therapist will help the stroke survivor regain language skills. In addition to speech, brain injuries can affect the victim's muscle tone and strength. A physical therapist can help stroke victims regain strength and balance, as well as learn to cope with new limitations. Physical therapy can take place in a rehabilitation center or in a skilled nursing home.

Two major arteries supply the brain with blood. These arteries are the internal carotid artery and the vertebral artery. The vertebral artery joins with the internal carotid artery in the Circle of Willis. Over eighty percent of the cerebrum is supplied by these arteries. Both supply the brain with oxygenated blood. However, the most common artery to become blocked during a stroke is the middle cerebral artery.

If you experience symptoms of TIA, call your doctor immediately. You should seek immediate medical attention for any TIA. But even if the symptoms are not severe, they are still a warning sign of a larger stroke.

A doctor may prescribe clot-busting drugs, such as aspirin or warfarin, to dissolve blood clots and restore blood flow to the affected brain area. These medicines are usually given intravenously by emergency medical staff. In addition to medicines to prevent high blood pressure, doctors may also perform surgery to unclog a blocked carotid artery. These procedures help people recover and prevent future strokes.

An MRI of the head is also recommended. This procedure uses radio frequency pulses and a powerful magnetic field to create detailed pictures of internal organs and structures. MR can help physicians determine if clots originating in the heart have traveled to the brain. A cerebral angiogram is another test that provides a detailed picture of the blood vessels in the neck. It can also show whether or not the clots caused a stroke.
