  Description

A stroke, also called cerebrovascular accident (CVA) or brain attack., is the loss of brain functions due to the deficiency of blood supply to the brain. This is caused by:

- Lack of blood flow (or ischemia) caused by the physical blockage of blood flow to an area of the brain. The most common forms of ischemic stroke are:

            - Embolic Stroke. It is caused by blockage of one of the arteries to the brain by a blood clot. This clot is usually formed in the heart and travels to the brain as an embolus until it reaches a narrow point where it becomes trapped.

             - Thrombotic Stroke. In this type of stroke a blood clot forms along the inside of a blood vessel. This clot is called thrombus and usually affects small blood vessels in the brain.

- Leakage of blood (or hemorrhage). It occurs when a blood vessel inside of the brain ruptures. As consequence, blood accumulates in or around healthy brain tissue.

Stroke symptoms typically start suddenly, without warning, and depend on the area of the brain affected.

  Diagnosis

Diagnosis starts with a physical examination. The following tests can help to determine the stroke's characteristics:

- Blood tests, including complete blood count, cholesterol, clotting tests, and bleeding time.

- Electrocardiogram.

- Echocardiogram.

- Swallow test (check for swallowing difficulties).

- Arteriography.

- Carotid ultrasound.

- Imaging tests (CT or MRI).
