A Stroke is a medical condition in which poor blood flow to the brain results in cell death There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Ischemic stroke constitutes an estimated 87 percent of all stroke cases. Stroke often occurs with little or no warning, and the results can be dangerous.
Intracerebral Hemorrhage(stroke)
A kind of stroke caused due to bleeding inside the brain tissue is called intracerebral hemorrhage. Usually, stroke occurs when the brain is deprived of oxygen due to an interruption of its blood supply. The main causes for intracerebral hemorrhage are hypertension,arteriovenous malformations or head trauma
How it occurs?
Due to high blood pressure or hypertension, the walled arteries break and blood spreads into the brain tissue. These blood forms a clot which is known as hematoma. The hematoma grows slowly and causes pressure on the surrounding brain tissue. This pressure makes a person experience tension and lethargic. When the blood spill into the brain, the area that artery supplied will lack oxygen and rich blood. This condition is called stroke. The surface or in deep areas of the brain is the main platform where intracerebral hemorrhage takes place.The symptoms of intracerebral hemorrhage is sudden which requires immediate action. The symptom may alter according to the location of the bleed.
Some of the common symptoms are :
- Nausea
- Vomiting
- Sudden weakness
- Numbness of face, leg and arm
- Seizures
- Temporary loss of vision
- Confusion or lethargy
- Loss of consciousness etc.
Surgery
If any doctor sees that an aneurysm has burst, then a surgery may be done to clip the aneurysm and prevent additional bleeding. Likewise, a craniotomy may be needed to relieve the pressure on the brain after a large stroke.
