While I was waiting to go back to my
usual self, I managed to learn deeply various elements of what I’m presently
engaged at and currently suffers from. Through some research on the internet
and medical books, I have found out that stroke statistics would present that,
• more than half a million people in
the United States experience a new or recurrent stroke each year;
• stroke is the third leading cause of
death in the United States and the leading cause of disability;
• stroke kills about 150,000 Americans
each year, or almost one out of three stroke victims;
• three million Americans are
currently permanently disabled from stroke;
• in the United States, stroke costs
about $30 billion per year in direct costs and loss of productivity;
• two-thirds of strokes occur in
people over age 65;
• strokes affect men more often than
women, although women are more likely to die from a stroke; and,
• strokes affect blacks more often
than whites, and are more likely to be fatal among blacks.
I have
also noted that this fatal illness is most likely to strike to Asians.
Moreover, it is stated that a stroke occurs when blood flow is interrupted to part
of the brain. Without blood to supply oxygen and nutrients and to remove waste
products, brain cells quickly begin to die. Depending on the region of the brain
affected, a stroke may cause paralysis,
speech impairment, loss of memory and reasoning ability, coma, or death. A stroke is also
sometimes called a brain attack.
Amongst are the clearer views of what
are the types:
“There
are four main types of stroke. Cerebral thrombosis and cerebral embolism are caused by blood clots
that block an artery supplying the brain, either in the brain itself or in the
neck. These account for 70–80% of all strokes. Subarachnoid hemorrhage and intracerebral hemorrhage occur when a
blood vessel bursts around or in the brain. Cerebral thrombosis occurs when a
blood clot, or thrombus, forms within the brain itself, blocking the flowof
blood through the affected vessel. Clots most often form due to “hardening” (atherosclerosis) of brain arteries.
Cerebral thrombosis occurs most often at night or early in the morning.
Cerebral thrombosis is often preceded by a transient ischemic attack, or TIA, sometimes called a
“mini-stroke.” In a TIA, blood flow is temporarily interrupted, causing
short-lived stroke-like symptoms. Recognizing the occurrence of a TIA, and
seeking immediate treatment, is an important step in stroke prevention.
Cerebral embolism occurs when a blood clot from elsewhere in the circulatory
system breaks free. If it becomes lodged in an artery supplying the brain,
either in the brain or in the neck, it can cause a stroke. The most common
cause of cerebral embolism is atrial fibrillation, a disorder of the heart
beat. In atrial fibrillation, the upper chambers (atria) of the heart beat
weakly and rapidly, instead of slowly and steadily. Blood within the atria is
not completely emptied. This stagnant blood may form clots within the atria,
which can then break off and enter the circulation. Atrial fibrillation is a
factor in about 15% of all strokes. The risk of a stroke from atrial
fibrillation can be dramatically reduced with daily use of anticoagulant
medication.” (GALE ENCYCLOPEDIA OF
MEDICINE 2,-Stroke)

And below classifies my stroke:
“Hemorrhage,
or bleeding, occurs when a blood vessel breaks, either from trauma or excess
internal pressure. The vessels most likely to break are those with pre-existing
defects such as an aneurysm. An aneurysm is a “pouching out” of a blood vessel
caused by a weak arterial wall. Brain aneurysms are surprisingly common.

Intracerebral
hemorrhage affects vessels within the brain itself, while subarachnoid
hemorrhage affects arteries at the brain’s surface, just below the protective
arachnoid membrane. Intracerebral hemorrhages represent about 10% of all
strokes, while subarachnoid haemorrhages account for about 7%.” (Ibid)
