Even though strokes are the leading cause of preventable deaths, very few people know much about them. So, the American Stroke Association has published a list of things you didn’t know about strokes for its 20th anniversary. Here are the top 10.
- There are three different types of strokes: Ischemic, Hemorrhagic, and TIA (Transient Ischemic Attack). Ischemic occurs as a result of an obstruction within a blood vessel supplying blood to the brain. It accounts for 87 percent of all stroke cases. Hemorrhagic occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause hemorrhagic stroke: aneurysms and arteriovenous malformations(AVMs). But the most common cause of hemorrhagic stroke is uncontrolled hypertension (high blood pressure). TIA is caused by a temporary clot. Often called a “mini stroke”, these warning strokes should be taken very seriously.
- During a stroke, nearly 120 million brain cells die every hour. Compared with the normal rate of cell loss in brain aging, the brain ages 3.6 years each hour without treatment. The sooner the patient gets medical care, the better their chances of recovery.
- About 66 percent of the time, someone other than the patient makes the decision to seek treatment – recognizing the warning signs and sudden symptoms of stroke to receive treatment fast, could help save a life.
- F.A.S.T. is an acronym used to teach the most common warning signs and sudden symptoms of stroke. F.A.S.T. stands for (F) face drooping, (A) arm weakness, (S) speech difficulty, (T) time to call 9-1-1. Less than half of the population is aware of the signs.
- Stroke symptoms can also include sudden numbness, sudden trouble seeing in one or both eyes, sudden severe headache with no known cause and sudden trouble walk
- Calling 9-1-1 and arriving at the hospital in an ambulance is the fastest way to get treated quickly during a stroke emergency. Driving to the hospital is a common mistake people make, that can result in longer wait times before the patient receives medical care.
- Patients who have an ischemic stroke, may have a treatment window for mechanical clot removal within six hours to up to 24 hours in certain patients with clots in large vessels.
- Alteplase (also known as tPA) is a drug used to dissolve a blood clot that causes stroke. Stroke patients who arrive at a hospital within 90 minutes of symptom onset and qualify to receive tPA are almost 3 times more likely to recover with little or no disability.
- Nearly half of all adults in the U.S. (an estimated 103 million) have high blood pressure.
- High blood pressure is the most common controllable cause of stroke. Recent guidelines redefined high blood pressure as a reading of 130/80 mm Hg or higher. A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg in an adult.
