What is a stroke?
A brain attack is referred to as a stroke. Anyone can be affected, and it can happen at any time. It happens when the supply of oxygen to any part of the brain is cut off and blood flow is restricted. When this happens, brain cells become oxygen-depleted and die.
Functional abilities regulated by this part of the brain, such as memory and muscular control, are lost as a result of the death of brain cells in a stroke. A stroke necessitates rapid medical attention and is potentially fatal. Even after the incident has concluded, it might influence many sections of the body.
Types of stroke
These are the types of stroke
Ischemic stroke is usually caused by atherosclerosis (hardening of the arteries), embolism (blockage of blood vessels by blood clots from other parts of the body), or microangiopathy (disease of the small arteries, the occlusion of small vessels in the brain)
It is usually caused by high blood pressure, arteriovenous malformations, brain aneurysms, and trauma.
They are usually the result of poor blood flow to the brain due to blocked arteries in the neck (due to atherosclerosis) or periods of poor heart function, such as during a heart attack.
What causes a stroke?
Brain cells are very fragile and require a constant supply of oxygen, and even brief interruptions in the supply of oxygen can lead to injury.
There are three main categories of causes of stroke: –
First, the blood transfusion to the brain can be blocked: small clots (emboli or thrombi) can block the vessels that carry blood to parts of the brain, or the vessels themselves can narrow, reducing the amount of blood to the brain. the brain (as seen in Moyamoya syndrome, for example).
Second, the blood may not get enough oxygen to start (such as in cases where someone cannot breathe for long periods of time or against the background of carbon monoxide poisoning) or the blood may not circulate fast enough to bring in fresh blood. oxygen to the brain (as could happen if the heart is not beating properly).
Finally, the brain itself may be under pressure (as happens in swelling of the brain after trauma or when there is bleeding around the brain) or there may be bleeding into the very substance of the brain, directly damaging brain tissue and also making it more difficult. so that the oxygen-containing blood reaches you. In these cases of increased pressure, the oxygen-containing blood from the heart cannot penetrate the boundaries of the skull if the pressure is too high.
What are the symptoms of a stroke?
The loss of function of the parts of the brain injured by a stroke can be seen by the effects on the patient. The symptoms (deficits) the patient will have will depend on the part of the brain that was injured by the stroke.
Parts of the brain may have strokes with little or no recognizable symptoms, although lesions may be seen on MRIs or CT scans (so-called “silent” strokes). Other strokes, even very minor ones, can cause devastating symptoms, such as paralysis, blindness, and even death if they occur in sensitive areas of the brain.
The treatment of a stroke has two components: –
First, the underlying cause of the stroke (such as high brain pressure, narrowing of blood vessels, or an increased tendency for blood to clot inappropriately) should be diagnosed and corrected, if possible.
Second, whatever The causes of the stroke treatment resulting problems (weakness, numbness, etc.) can sometimes be improved with treatment over time Identifying patients who may benefit from specialized therapy may require evaluation by specific healthcare professionals, such as neurologists, rehabilitation physicians, physiotherapists, occupational therapists, or speech-language pathologists.
The Department of Neurosurgery works with many different health care teams in a multidisciplinary effort dedicated to the treatment which is the best hospital for brain stroke treatment in Coimbatore.
