Stroke – Causes, Symptoms and Treatments

You can take certain steps to prevent stroke like manage stress through exercise, avoid usage of alcohol, quit smoking, control diabetes, treat circulation problems, regular check on blood pressure and other preventive measures. Stroke specialists can be easily availed at hospitals where high quality equipment is used to treat the patients.

Stroke is a treatable disease that can be suspected as a result of aging that certainly leads to  severe disability or even death of a person. It is caused when an artery through the brain ruptures or the blood stops flowing. Consequently, it results in failure of functioning of brain as the cells die due to lack of oxygen. The movement of several parts of the body depends upon such cells therefore it results in various problems. Some of those problems are inability to speak properly, patient may lose his memory or even have paralysis attack. Factors like high blood pressure and high cholesterol, diabetes, smoking, etc can result in stroke especially among the elderly people.

There are mainly two types of stroke. They are:

1. Ischemic stroke: It occurs when a blood clot or thrombus blocks the blood flow. Also, if it is found in other parts of the body and freely floats in the blood, it is called as embolus. This moving clot is carried via bloodstream to the brain where it causes ischemic stroke.

2. Hemorrhagic stroke: It occurs when a blood vessel on the surface of brain bursts  (subarachnoid hemorrhage) or when an artery in the brain breaks off and the nearby tissue fills with blood(cerebral hemorrhage).

Symptoms of Stroke
The symptoms of stroke can be recognized easily. It is important for you to seek advice from your doctor so that he can give medical aid as early as possible. Several symptoms of the stroke include TIA (Transient Ischemic Attack), dizziness, severe headache, perception problems and numbness in the body. Small or silent strokes may not cause any symptoms but can still damage brain tissue.

Stroke Treatments
The stroke is diagnosed via ultrasound, arteriography, MRI or any other quality-approved imaging equipment that help doctors to understand the problem before starting the treatment. Medicines like aspirin, heparin,etc. are used to restore the flow of blood. Surgical operations like carotid endarterectomy and angioplasty are done to open up the arteries. Also, treatments like aneurysm clipping, aneurysm embolisation and arteriovenous malformation (AVM) removal help to treat hemorrhagic stroke. In aneurysm clipping method, a small clamp is kept at the base of aneurysm that makes it isolated from its attached artery and allows it to burst. In aneurysm embolisation ttreatment, a catheter( tiny coil) is placed in the aneurysm, causing clotting and isolation from arteries. AVM removal is a surgery to remove AVMs found in the major portions of brain and reduce the chances of blockage or rupture.  In order to gather more information about strokes or its treatments, please refer to the web.
