Stroke occurs when one of the vessels that
provide blood flow to the brain is suddenly blocked, and the flow of blood flow
to the brain slows or stops.
Stroke is one of the most important causes of death in the
world after heart disease and cancer. The average person in the US has a
stroke per minute; One person dies in three minutes from a stroke. Stroke,
a cerebrovascular disease, is the most important cause of disability in the
Stroke occurs when one of the vessels that provide blood flow
to the brain is suddenly blocked, and the flow of blood flow to the brain slows
or stops. It can also occur as a result of the sudden rupture of one of
the brain vessels and the flow of blood into the brain tissue, and this is
popularly called cerebral hemorrhage.
Hypertension, diabetes, heart disease, smoking, high
cholesterol and transient ischemic attacks are among the risk factors that
cause stroke. Uncontrolled hypertension is the most important cause of
cerebral hemorrhage, which has a more limited place among stroke cases. Hereditary
diseases such as bubbles in the vessels of the brain and vascular ball are
among the causes of cerebral hemorrhage. These vascular tangles, which
remain silent for a long time in a part of the brain, can suddenly bleed one
day. Obstructive strokes, which are a more common type of stroke, can be
evaluated in 5 categories.
Cardiac obstructions constitute the most important category. Clots
that may form in the heart can break off and block the brain vessels. For
example, in the heart that has had an infarction, a certain part of the heart
muscle can lose its function. As a result, since the heart cannot contract
effectively, clots can accumulate there. In a rhythm disorder that may
occur, this clot can jump out of the heart and travel to the brain. The
second important category is the problems seen in the major vessels that
nourish the brain. Problems in the carotid (carotid artery) and vertebral
arteries in the posterior regions of the brain and the vessels that irrigate
the brainstem and cerebellum also cause stroke.
The third category is the problems with the small vessels
that irrigate the deep regions of the brain. For example, chronic diseases
that disrupt the vascular bed such as diabetes, high cholesterol and
hypertension can cause this. If a large vein is gradually clogged, the
remaining intact veins start to feed the area of the
occluded vein, but this does not happen in small veins. Therefore, with
the sudden occlusion of small vessels, the area they nourish can be completely
bloodless. This is because of the negative and devastating effects of
hypertension on end vessels over the years.
The fourth category consists of rare causes. When the
patients in this group are examined thoroughly, hereditary diseases, vascular
problems that occur as a part of rheumatic diseases or hematological problems
related to blood clotting can be found. In addition, dissections in which
large vessels suddenly rupture can be evaluated in this group. Dissections
are an important cause of stroke in the young age group. Stroke should not
be perceived as an old age disease. This disease can also be seen in
childhood. Dissections are a major cause of childhood strokes. It can
occur even at birth.
The last group consists of strokes of unknown cause. This group accounts for
10-30 percent of obstructive strokes.
