Stroke Awareness and Treatment



Sudden death of the brain cells due to the lack of blood supply to brain may cause stroke. Brain cells quickly die due to lack of blood as blood supply oxygen and nutrients and remove waste products. Based on the parts of the brain affected a stroke may cause paralysis, loss of memory and reasoning ability, impairment, speech coma, or death. A stroke also is sometimes called a brain attack or a cerebrovascular accident (CVA).

Paralysis

Paralysis occur as a result of stroke. One side of the body is affected which is opposite to the damaged part of the brain by stroke. If right side of the brain is damaged, paralysis occur on the left side of the body. This one-sided paralysis is called hemiplegia. Stroke patients with hemiparesis or hemiplegia may have difficulties in walking or grasping objects. Some stroke patients have problems with swallowing, called dysphagia, due to damage to the part of the brain that controls the muscles for swallowing. Damage to the lower part of the brain, the cerebellum, leading to problems with body posture, walking, and balance which may cause the body’s ability to coordinate movement which leads a disability called ataxia.

Most major types of stroke include:

Right-Hemisphere Stroke

A stroke in the right hemisphere of the brain cause paralysis in the left side of the body. This is known as left hemiplegia.

Left-Hemisphere Stroke

The left hemisphere of the brain controls speech and language abilities for most people. It also controls the movement of the right side of the body. A left-hemisphere stroke often causes paralysis of the right side of the body. This is known as right hemiplegia.

Brain Stem Stroke

The brain stem serves as a bridge in the nervous system. All the fibers that go from the body to the brain and vice versa go through the brain stem. Strokes that occur in the brain stem are traumatic. The brain stem controls abilities such as eye movements, hearing, speech and swallowing. The symptoms of a brain stem stroke are more serious and complex than other strokes.

When a stroke occurs, fast action is needed. The sooner a stroke victim gets emergency care, the more brain tissue can be saved. If anyone experiences the sign of a stroke, such as slurred speech, confusion, and weakness on one side of the body, get them emergency care. Once the symptoms are stabilized, the attention turns to recovery. Initially, patients get in-hospital rehabilitation care, including physical therapy and occupational therapy, to address the impacts of the stroke. After discharge, most stroke patients continue to need outpatient rehab and may also require in-home caregiving support.
