Brain Attack
Brain Attack Causes
A brain attack is caused by a severe decrease in the amount of blood that supplies the brain. In some cases, an attack may also be caused by too much blood accumulating in the skull.
Brain Attack Definition
Brain attack is a type of stroke that occurs from a drastic shortage of blood supply in the brain. Brain cells will commonly die in a matter of minutes. A brain attack is more commonly referred to as a stroke.
Brain Attack Diagnosis
To diagnose the type and location of the brain attack, the following steps may be taken: physical examination and tests; carotid ultrasonography; arteriography; computerized tomography (CT) scan; magnetic resonance imaging (MRI) test; and an echocardiography.
Brain Attack Symptoms and Signs
Hallmark signs and symptoms of a brain attack are: aphasia or sudden difficulty speaking or comprehending language; sudden weakness, numbness, or paralysis of limbs or the face, usually on one side of the body; sudden dizziness accompanied by loss of balance or loss of coordination; sudden double, blurred, or decreased vision; sudden severe headaches; as well as confusion, memory problems, and loss of spatial perception. Often, a stroke or brain attack may suddenly occur without warning.
Brain Attack Treatment
A brain attack is a medical emergency; therefore, affected patients must be given urgent medical treatment. Treatment usually involves: immediate injection of clot-busting drugs; carotid endarterectomy; and angioplasty. Preventive medications such as anti-platelet drugs and anticoagulants may also be recommended.
