Symptoms of stroke include sudden confusion, trouble speaking, sudden vision trouble and difficulty walking as well as loss of balance, dizziness and sudden headache with no cause, according to the National Stroke Association. Sudden weakness or numbness of the face, leg or arm, particularly when localized to one side, is also a symptom.
Knowing the symptoms of a stroke and seeking treatment right away is paramount to a positive outcome, according to the National Stroke Association. Around 1.9 million neurons are lost for every minute that treatment is delayed following symptoms of a stroke. Blocked blood flow to the brain can detrimentally affect the person’s memory, movement, speech and more.
Symptoms of stroke vary depending whether the stroke is an ischemic stroke, which is caused by a blood clot, or a hemorrhagic stroke, which is caused by bleeding, notes WebMD. Most strokes occur suddenly, but the symptoms may also occur over a period of several hours, with weakness being mild at first and then progressing to the point that it is impossible to move a leg or arm on one side of the body.
There are several risk factors for stroke, according to WebMD. These include high blood pressure, smoking, diabetes, obesity and physical activity. Women are more likely to have a stroke than men, and those with a family history of stroke are also at increased risk.
