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. A hemorrhagic stroke is very dangerous because the accumulated blood from the burst artery may put pressure on surrounding brain tissue and interfere with how the brain functions. Some 80 percent of all strokes are caused by clots. There are now drugs that can help with this type of stroke.
