Transient ischemic attacks (TIA) are a type of stroke, characterized by decreased blood flow in the vessels that supply the brain. TIA symptoms vary from a mild change in mental acuity to obvious numbness or weakness. Although they are not a primary symptom of stroke, they may be warning signs of an impending stroke. These symptoms may vary from a change in speech to loss of sensation and coordination.

The most important CVA stroke symptoms are based on the region of the brain affected. In some cases, blood flow to the brain can be impaired by a clot or a leak in a blood vessel. These events block or obstruct blood flow to the brain, causing symptoms ranging from numbness to dizziness and confusion. The duration of these symptoms depends on the type of CVA and the extent of the damage.

Transient ischemic attack symptoms are similar to those of a stroke, but will resolve on their own. A transient ischemic attack can be a precursor to a more debilitating CVA. One third of all strokes begin with a TIA, which may be difficult to recognize because of its temporary nature. As with all symptoms of stroke, time is crucial, so seek medical attention right away if you experience any of these symptoms.

Ischemic strokes are the most common type of stroke. When an artery to the brain becomes blocked, a part of the brain that is supplied by the clotted blood vessel is deprived of oxygen and blood. This results in the death of cells in the affected area. When this happens, the plaque on these blood vessels begins the clotting process. A CVA stroke may be fatal if the patient fails to receive proper treatment.

If CVA stroke symptoms occur, contact 9-1-1 and seek immediate emergency care. The first goal of treatment is to restore the blood supply to the brain. After that, the blood supply to the brain will be restored by clotting-busting drugs. The affected person will need emergency medical care within three to four and a half hours. A person will need to be evaluated by a medical professional to determine which treatment is the best. If they are unable to perform their usual daily activities, treatment can help improve their chances of recovery.
