What is stroke?
Stroke is defined as condition in which the brain function is interrupted rapidly due to the loss of blood supply
as a result of the blockage of blood such as thrombosis and arterial
embolism, or leakage of blood causes of the death of brain cells,
according to the article of Mitochondria, oxidative metabolism and cell death in stroke by Sims NR, Muyderman H (September 2009).
Stroke is caused by cholesterol build up in the arteries and high blood
pressure. In other words, if cholesterol building up in the arteries is
blocking the circulation of blood in any part of the body causing
oxygen not to be delivered to the brain, resulting in some cells in the
brain to die off and are unable reproduce,
Besides cancer and heart
diseases, stroke is the third leading cause of death. Approximate 1/4 of
all stroke victims die as a direct result of the stroke or it's
Women and stroke
to the statistic of the Heart and Stroke Foundation, strokes kill 45%
more women than men in Canada. In the study, published in the journal Neurology,
researchers from the University of California at Los Angeles monitored
17,000 people over a period of six years. They found the incidence of
stroke rising faster among women than men.When women reach the age of
45, the risk of stroke begins to rise rapidly, it may be due to levels
of estrogen has dropped significantly at age 45 and onward.
1. Sudden trouble in standing
trouble in standing is an early symptom of stroke as a result of
circulation of blood that carries oxygen to suddenly deplete caused by
narrowing of arteries and high blood pressure.
2. Dizziness and loss of balance
brain coordinates information from the eyes, the inner ear, and the
body's sense to maintain balance. If the cells of that part of the brain
get damaged in result of depleted oxygen will cause dizziness and loss of balance.
3. Sudden confusion
sudden onset of confusion means that something is potentially going
wrong with the brain. Almost all conditions that affect the brain are
life-threatening. It might be caused by a tumor or low levels of oxygen
in the cells of the cerebral cortex in your brain that affect your
ability to think with your usual speed or clarity. It might also be
caused by lowered blood sugar, as is the case of diabetes.
4. Having trouble speaking and understanding
Having trouble speaking and understanding occurs when the brain cells in the area of the broca, wernicke and angular ayrus in the left hemisphere area begin to die because they stop getting the oxygen and nutrients they need to function.
6. Sudden severe headaches
is a condition of pain in the head, sometimes neck or upper back pain
may also be interpreted as a headache. It ranks amongst the most common
local pain complaints and may be frequent for many people but sudden severe headaches may
be caused by an early symptom of heart disease as we mentioned in
previous articles, by rupturing a brain vessel or depletion of oxygen in
some parts of the brain.
7. Sudden trouble seeing
This may be
an early indication of stroke when the oxygen in the blood supply to
the part of the brain is suddenly interrupted or when a blood vessel in
the brain bursts, spilling blood into cells that control the vision area
of the cerebral cortex in the brain.
