What are the warning signs of a stroke?
There may be no warning signs of a stroke until it occurs. It is why high blood pressure (hypertension), one of the risk factors for stroke, is called the silent killer.
Some patients may experience transient ischemic attack (TIA) that can be thought of as a stroke that has resolved itself. The symptoms may be mild or dramatic and can mimic a stroke with weakness, numbness, facial droop, and speech difficulties, but these symptoms may only last few minutes. TIAs should not be ignored since they may offer an opportunity to look for potentially reversible or controllable causes of stroke. As well, there is no guarantee that the symptoms of stroke will resolve on their own. For that reason, a TIA should be considered an emergency and medical care should be accessed immediately.
