Signs Stroke warning signs may be temporary. They may go away after a few hours. They may even go away in a few minutes. But regardless of how long the symptoms last, AANS says it's essential that anyone experiencing the symptoms of stroke seeks immediate medical help. A TIA is a temporary situation in which you suddenly experience the symptoms of a stroke, but then the symptoms go away after a few minutes.
People often ignore a TIA, thinking the problem has disappeared.
This can be a fatal mistake because a TIA is serious warning. In fact, according to AANS, approximately 10 to 15 percent of patients who have TIAs will suffer a stroke within one year of the first attack. The American Heart Association says silent strokes are far more common than once thought. Basically, silent strokes occur when small blood vessels in the brain become blocked or rupture. But eventually, as blood and oxygen supply to the brain diminishes, cells die.
