As stroke is a medical emergency. Strokes happen when blood flow to your brain stops within minutes and brain cells begin to die.
Symptoms of strokes:
Stroke is sudden it includes:
- Numbness or weakness of the face arm or leg especially on one side of the body
- Sudden confusion
- Trouble speaking or understanding speech
- Sudden trouble seeing in one or both eyes
- Trouble walking
- Loss of balance or coordination
- Severe headache with no known cause
What are types of stroke
Stroke results from a sudden disruption of blood flow to the brain and there are two major types of stroke.
- Ischemic stroke
- Hemorrhagic stroke
1. Ischemic strokes:
This stroke is one that results from a blood vessel being occlude or plugged by a piece of a blood clot. However, Strokes often occur with little or no warning and the results can be devastating. These are further categorize into:
- Thrombotic type
- Embolic type
• Thrombotic type:
Thrombotic is the most common type of ischemic stroke. A blood clot forms inside a damaged artery in the brain resulting from atherosclerosis. It is a cholesterol-containing deposit called plaque. This blocks the blood flow.
• Embolic type:
The other is embolic stroke which is cause when a clot or small piece of plaque forms inside one of the arteries. So, it is push through the bloodstream and lodges in the narrower brain arteries. The blood supply is cut off from the brain due to the clogged vessels. Common temporary symptoms include:
- Difficulty in speaking
- Blurring of vision
- Loss of strength
- Numbness in an arm or leg
2. Hemorrhagic strokes:
Stroke resulting from a rupture or a burst blood vessel in the brain. That type of stroke is called a hemorrhagic stroke. Two types of hemorrhagic stroke are:
- Intracerebral hemorrhage
- Sub arachnid hemorrhage
• Intracerebral hemorrhage:
In Intracerebral hemorrhage, bleeding occurs from the blood vessels within the brain parenchyma. Moreover, it is usually cause by hypertension (high BP). So, Bleeding occurs suddenly and rapidly. It has no warning signs. So, bleeding can cause coma or death.
• Subarachnoid hemorrhage:
In Hemorrhagic stroke subarachnoid, bleeding occurs between the brain and meninges (that is the membrane that covers the brain). In the subarachnoid space, causes of subarachnoid hemorrhage is often due to an aneurysm or arterial venous malformation. Diagnosis of hemorrhage stroke include severe headaches, nausea, and vomiting. An aneurysm is a weak ballooned area on an artery wall and has a risk of rupturing. Aneurysm may be congenital that is present at birth or may develop later in life the cause of arteriovenous malformation is unknown but it is sometimes genetic or part of certain syndromes.
Ischemic stroke vs Hemorrhagic stroke vs TIA:
The more common kind called ischemic stroke. It is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind called hemorrhagic stroke. It is caused by a blood vessel that breaks and bleeds into the brain. Many strokes or transient ischemic attacks (TIA) occur when the blood supply to the brain is briefly interrupted.
How many strokes can a person have?
Stroke has no limit it mostly depends upon patient condition. Generally Ischemic stroke occurs in approximately 87 percent and hemorrhagic stroke is about 13 percent of all stroke cases.
Treatment of stroke:
- Patient gets to a hospital quickly to begin treatment for acute stroke. Medical staff try therapies to stop a stroke while it is happening by quickly dissolving the blood clot or by stopping the bleeding.
- Post stroke rehabilitation helps individuals overcome disabilities that result from stroke damage.
- Drug therapy also helps that uses blood thinners. It is the most common treatment for stroke.
