Immediate Medical Attention
An individual experiencing a stroke can have a variety of warning symptoms that include weak muscles, altered sense of smell, balancing difficulties, blurry vision, slurred speech, and numbness in limbs. The symptoms of stroke primarily occur on one side of the body due to changes in the blood flow of one hemisphere of the brain. If a stroke is suspected in an individual, immediate medical attention is necessary. The best plan is to call an emergency number to have the individual transported to a hospital by ambulance. At an emergency room, physicians will work quickly to treat a patient to avoid permanent neurological damage.
Dangerous Arterial Embolisms
Cerebrovascular accidents are caused by blockages that change the blood supply to the brain. An arterial embolism or blood clot in a vein is a common reason for loss of blood flow in the body. Occasionally, these clots form in major arteries, leading to a major interruption in the flow of blood. Narrowing of the arteries or atherosclerosis commonly causes embolisms. Atherosclerosis happens as triglycerides and cholesterol accumulate on artery walls, creating a thinner passageway for the flow of blood. Atherosclerosis increases the susceptibility of an individual having a stroke because clots easily become stuck in the blood vessels.
There are additional risk factors for having an arterial embolism, including smoking cigarettes, having diabetes, being overweight, high blood pressure, lack of exercise, and aging. Individuals can often make lifestyle changes while taking prescription medication to reduce the chances of having a stroke. When a clot first develops, an individual will have a transient ischemic attack that lasts a few minutes. If the condition is not treated immediately, serious damage occurs due to lack of oxygen reaching the brain. Patients will undergo diagnostic radiological tests to assist physicians with observing the blood flow inside the heart, neck, and brain.
There are several surgical procedures to remove an embolus, such as embolectomy, angioplasty, and thromboaspiration. Several medications, including vasodilators and anticoagulants, assist with dilating and dissolving the life-threatening blood clots. Rapidly correcting the blood flow to the brain is vital for preventing additional loss of motor functions, such as speech and balance. After a stroke, patients frequently require a variety of therapies to regain the ability to walk or talk. Many individuals never completely recover from a stroke, leading to disabilities requiring wheelchairs, walkers, and canes.
