Others may undergo a type of test called cerebral arteriography, which maps the blood supply to the brain so that doctors can see where the blockage is occurring. The test can provide important information on whether to treat TIAs or stroke with surgery to remove the blockage. One type of surgery for TIAs is called carotid endarterectomy, in which doctors remove plaque from the carotid artery to improve blood supply to the brain. Acute care for people who have just suffered a stroke often includes life-support equipment to supply oxygen, nutrients and medications. The main goal of acute care is to help the patient survive by preventing another stroke and taking care of any other medical problems.
Most patients begin to spontaneously recover from their strokes, slowly regaining lost abilities.
This process is usually fastest during the first few weeks, but patients may continue to improve for a long time. The prognosis for every stroke patient is different, depending on where in the brain the stroke occurs, how much damage is sustained and the patient's overall health. Some patients will make a complete or nearly complete recovery. Others are disabled through the loss or partial loss of speaking ability or memory, while others suffer permanent paralysis or weakness. After a stroke, rehabilitation is vital to help the patient recover as quickly and completely as possible.
