Paralysis Research Paper

Paralysis is usually on the side of the body opposite the side of the brain damaged by stroke, and may affect any part of the body. If paralysis is considered as one side, it is known as hemiplegia or one-sided weakness, known as hemi paresis.
A stroke is when 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. They result in part of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, feeling like the world is spinning, or loss of vision to one side. Signs and symptoms often appear soon after the stroke

has occurred. If symptoms last less than one or two hours it is known as a transient ischemic attack (TIA) or mini stroke. A hemorrhagic stroke may also be associated with a severe headache.[2] The symptoms of a stroke can be permanent. Long-term complications may include pneumonia or loss of bladder control.
The main risk factor for stroke is high blood pressure.

Other risk factors include tobacco smoking, obesity, high blood cholesterol, diabetes mellitus, previous TIA and atrial fibrillation. An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes. A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. Bleeding may occur due to a ruptured brain aneurysm. Diagnosis is typically with medical imaging such as a CT scan or magnetic resonance imaging (MRI) scan along with a physical exam.
Prevention includes decreasing risk factors, as well as possibly aspirin, statins, surgery to open up the arteries to the brain in those with problematic narrowing, and warfarin in those with atrial fibrillation. A stroke is often requires emergency care. An ischemic stroke, if detected within three to four and half hours, may be treatable with a medication that can break down the clot. Aspirin should be used. Some hemorrhagic strokes benefit from surgery. Treatment will give to recover lost function is called stroke rehabilitation and ideally takes place in a stroke

unit.
In 2013 approximately 6.9 million people had an ischemic stroke and 3.4 million people had a hemorrhagic stroke. In 2015 there were about 42.4 million people who had previously had a stroke and were still alive. Between 1990 and 2010 the number of strokes which occurred each year decreased by approximately 10% in the developed world and increased by 10% in the developing world. In 2015, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.3 million deaths. About 3.0 million deaths resulted from ischemic stroke while 3.3 million deaths resulted from hemorrhagic stroke. About half of people who have had a stroke live less than one year. Overall, two thirds of strokes occurred in those over 65 years old.
Paralytic Stroke occurs when the blood supply to the brain is interrupted or reduced to a large extent, depriving brain tissues of essential oxygen and nutrients. When these cells do not receive oxygen and nutrients, they begin to die. This is considered a medical emergency and immediate medical treatment is essential to prevent further brain damage and possible implications [1].
II.TYPES OF STROKE:
Ischemic stroke:
A stroke caused due to a blocked artery
Hemorrhagic stroke:
A stroke caused by bursting or leaking of a blood vessel
Transient Ischemic Attack:
Is an episode wherein, the blood supply to the brain maybe temporarily interrupted causing a paralytic stroke.
Ischemic Stroke:
This type of stroke occurs when the arteries leading to your brain become narrow or get completely blocked causing reduced blood supply to the brain. This type of stroke can be further classified into two types:
