A stroke happens when blood flow to a part of the brain is interrupted because a blood vessel in the brain is blocked or bursts open. The sudden death of some brain cells due to a lack of oxygen when the blood flow to the brain is impaired by blockage (Ischemic) or rupture (Hemorrhagic) of an artery to the brain. Stroke is also called a Cerebrovascular Accident or CVA for short. Ischemic strokes are caused by the blockage of a blood vessel and Hemorrhagic strokes are caused by bleeding in the brain. the Ischemic Stroke is the most common and accounts for about 87 percent of all strokes.
The most common symptoms of a stroke include:
A stroke involving the base of the brain can affect balance, vision, swallowing, and breathing and even cause unconsciousness.
A stroke is a medical emergency. Anyone suspected of having a stroke should call 911. Calling 911 ensures immediate care and transfer to the most appropriate medical facility for diagnosis and treatment.
The Joint Commission describe studies that illustrate better outcomes when strokes are approached as a systematic plan. Early use of anticoagulants to minimize blood clotting has value in some patients as does treatment of blood pressure that is too high/low And controlling primary diseases such as Diabetes.
