Stroke

stroke neurology emergency_medicine cardiovascular
A stroke occurs when the blood supply to a part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. This can lead to brain cells dying within minutes, necessitating immediate medical attention.
Context: Hypertension

Hypertension, or high blood pressure, is one of the most significant risk factors for stroke. It can damage blood vessels, making them more prone to blockages or ruptures, which can lead to a stroke. Managing blood pressure through lifestyle changes and medications is crucial in reducing stroke risk.

What is a Stroke?

A stroke is a medical emergency that happens when the blood supply to part of the brain is interrupted or reduced. This deprives brain tissue of oxygen and nutrients, leading to the death of brain cells. Prompt treatment is critical to reduce brain damage and other complications.

Types of Stroke

  • Ischemic Stroke: The most common type, caused by a blockage in an artery that supplies blood to the brain.
  • Hemorrhagic Stroke: Occurs when a blood vessel in the brain bursts, leading to bleeding in or around the brain.
  • Transient Ischemic Attack (TIA): Often called a mini-stroke, it is a temporary period of symptoms similar to those of a stroke.

Risk Factors

Several factors can increase your risk of a stroke, including high blood pressure, smoking, diabetes, obesity, and high cholesterol.

Symptoms

Common symptoms of a stroke include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, confusion, trouble speaking, difficulty understanding speech, vision problems, dizziness, and a severe headache with no known cause.

Treatment

Treatment depends on the type of stroke. Ischemic strokes may be treated with medications like clot-busters, while hemorrhagic strokes may require surgery. Rehabilitation is a crucial part of recovery, helping stroke survivors overcome disabilities.
