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.
Causes of stroke in women
There are similar causes of stroke
and heart diseases, but in stroke the result is more severe. Any delay
of rescuing will result in death of the victim. Here are some causes of
1. Unhealthy diet
A diet high in saturated and trans fats
causes bad cholesterol to build up in your blood vessels in the brain,
blocking oxygen needed for the cells thus increasing the risk of stroke.
Also unhealthy diet causes high blood pressure making your heart work
harder to pump blood to your body in result of heart diseases. High
blood pressure also causes the blood vessels in your brain to harden and
thin, increasing the risk of stroke.
only has a devastating effect on the health of the smoker but also to
anyone that inhales its toxic fumes. Cigarettes contain high levels of
cadmium that causes the blood to clot activity of cells in result of
blocking blood flow and damaging the blood vessels in the brain.
3. Excessive drinking
Moderate drinking is good for your heart,
but excessive drinking can raise levels of some fats in your blood
causing cholesterol to build up in the arteries and blood vessels in the
brain resulting in increase of the risk of stroke.
with diabetes tend to develop heart disease or have strokes at an
earlier age than other people. Diabetes with unhealthy diet causes high
blood glucose levels that damage nerves and blood vessels, leading to
complications such as heart disease and stroke, the leading causes of
death among people with diabetes.
5. Obesity — a body mass index of 30 or higher
shows that even after adjusting for other stroke risk factors such as
high blood pressure, diabetes, high cholesterol, smoking, cardiac
diseases, moderate alcohol consumption, and physical activity; obesity
is still associated with a greatest risk of stroke in men and women.
6. Use of birth control pills
control pills contain estrogen and one of two other hormones,
lynestrenol or norethisterone that increase the risk of blood clotting,
which can lead to ischemic stroke especially in woman who smoke and who
are older than 35.
According to the article
published in the journal Neurology, Dr. Kurth and his colleagues looked
at 27,798 female health professionals ages 45 and older, including 3,568
who had migraines, from the Women's Health Study, researchers found
that women with once-a-week-migraines with auras -- who made up 5
percent of the women with migraines -- were four times as likely to have
had a stroke during the 12-year study as women without migraines, And
women who had migraines with auras less than once a month (75 percent of
the group) were more than twice as likely as migraine-free women to
have a heart attack, and almost twice as likely to have had a heart
procedure, such as bypass surgery. Overall, only 2.5 percent of women in
the study had experienced a stroke, heart attack, or related problem.
the article of Preeclampsia and Stroke: Risks during and after
Pregnancy by Cheryl Bushnell and Monique Chireau, researchers indicated
that although women with cerebrovascular manifestations of preeclampsia
are thought to be out of danger when the baby is delivered, accumulated
data show that women with preeclampsia are at risk for stroke and
cardiovascular disease well after the postpartum period and child
bearing years....... From a clinical perspective, preeclampsia should be
regarded as a risk factor for stroke in pregnancy as well as a
harbinger of future cerebrovascular disease, although there are many
gaps in our knowledge about who is at risk and when, as well as how to
best prevent preeclampsia and stroke in women.
9. Estrogen and progestin HRT
a sudy of Hormone replacement therapy and stroke, by Billeci AM,
Paciaroni M, Caso V, Agnelli G., researchers concluded that there seems
to be no indication for hormone replacement therapy in the prevention of
stroke in women. Further studies are needed to discover why estrogen
have different effects on the heart and brain. Conventional risk-factors
which could increase the risk of estrogen therapy need to be identified
and as well as more restrictive inclusion and exclusion criteria such
as coagulation parameters and intimal thickness should be adopted before
new randomized trials are started.
