Risk Factors Associated With Brain Stroke
3 min readA brain stroke occurs when the blood supply to a part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. The rupture or blockage prevents blood and oxygen from reaching the brain’s tissues. A brain stroke is a medical emergency that requires prompt treatment, and early action can minimize brain damage and potential complications. The way a stroke affects the brain depends on the part of the brain suffering an injury, and its degree. Brain stroke symptoms include blurred vision, numbness, difficulty in breathing, difficulty in speaking, problems with chewing or swallowing, partial or complete hearing loss, weakness of the limbs, etc.
Risk Factors Associated With Brain Stroke
Diplopia
Diplopia is the simultaneous perception of two images of a single object that may be displaced horizontally, vertically, diagonally, or rotationally with each other. It is usually the result of impaired function of the extraocular muscles, where both eyes are still functional, but they cannot turn to target the desired object. Diplopia is only evident when looking through both eyes and disappears if one eye is closed or covered. Diplopia can be one of the symptoms of a brain stroke, particularly to a muscular or neurological process, and it may disrupt a person’s balance, movement, or reading abilities.
Ataxia
Ataxia is a neurological sign consisting of a lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements. Ataxia is a dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum. Persistent ataxia usually results from damage to the part of the brain that controls muscle coordination. A brain stroke can cause ataxia and people with cerebellar ataxia may have trouble regulating the force, range, direction, velocity, and rhythm of muscle contractions. Ataxia can affect people of any age, and it is often progressive, which means that symptoms worsen over time. The rate of progression can vary by individual as well as by type of ataxia. Some of the most common symptoms of ataxia can include problems with coordination and balance, which can consist of clumsiness, an unsteady movement, frequent falling, slurred or unclear speech, tremors or muscle spasms, difficulties with eating or swallowing, and abnormal eye movements.
Vertigo
Vertigo is a symptom where patients feel as if they or the objects around them are moving when they are not. It is a sensation of feeling off-balance. Often it feels like a spinning or swaying movement due to dizzy spells. It may be associated with nausea, vomiting, sweating, or difficulties walking. Common causes of vertigo include brain stroke, brain tumour, brain injury, multiple sclerosis, etc. Attacks of vertigo can develop suddenly and last for a few seconds, or they may last much longer.
Paralysis
Paralysis is a loss of ability to move or function in one or more muscles. Paralysis can be accompanied by a loss of feeling in the affected area. Paralysis can affect the body in a variety of ways. In addition to making someone unable to move, paralysis makes nerves in the brain unable to communicate with parts of the body responsible for some bodily functions. There are several causes of paralysis, and brain stroke is one of them.
