6 Lesser known facts about Stroke
A stroke is a “brain attack”. It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost. Following are a few lesser known facts about stroke.
Stroke claims life every 4 minutes.
On an average in India, a stroke occurs every 40 seconds and every 4 minutes someone dies of stroke. Majority are referred to as “silent” strokes. These are the most common type of strokes. The word “silent” misguides people. When subjects with “silent” infarcts are examined, they have subtle neuropsychological and neurological deficits.
Most strokes are not painful.
Eighty per cent of strokes are caused by a blood clot in the brain and usually do not hurt, although some do. Stroke cuts off oxygen to a part of the brain. Brain cells begin to die but this is usually not painful. Don’t ignore symptoms because they don’t hurt. Only 20% of strokes are caused by bleeding inside the brain, and this type of stroke is usually very painful.
Strokes affect children as well.
While the vast majority of strokes occur in individuals aged 65 or older, around two-thirds, stroke can occur in those much younger. In fact, stroke remains a top cause of death in children. Strokes can happen in children, young adults and even infants in utero, which is why it’s important to never rule out stroke exclusively because of age.
50% of strokes due to high blood pressure.
Half of all the strokes in India can be attributed to high blood pressure. It is very important to find out if you are at risk for high blood pressure, diabetes or high blood cholesterol. Uncontrolled high blood pressure can lead to a stroke by damaging and weakening your brain’s blood vessels, causing them to narrow, rupture or leak.
Strokes result in disability.
Stroke is the leading cause of disability and the 5th leading cause of death worldwide. It results in long-term or permanent impairments. A stroke affects the arteries leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or ruptures.
Small stroke leads to a major stroke.
One-fourth of all strokes in India occur in people who have already had a small stroke. These patients are at substantial risk of a major stroke, death, heart failure or a heart attack within the next decade. Research says that 60% of the patients who had a small stroke had died and 54% had a least one heart attack or a stroke.
