Stroke

A stroke, often referred to as a cerebrovascular accident (CVA), is a dangerous medical condition that develops when there is an interruption in the blood flow to a part of the brain. Various reasons can cause this disruption, which prevents the brain from getting the nutrition and oxygen it requires to function normally. In turn, this can cause brain cells to become damaged or die, which can have a variety of long-term effects and neurological symptoms.

There are two main types of strokes:

1. Ischemic Stroke: With over 85% of all strokes falling within this category, it is the most common type of stroke. It happens when a blood vessel that supplies blood to the brain narrows or becomes blocked, frequently as a result of a blood clot. A blockage may arise from another the body, such as the heart (embolic stroke), or it may happen in the blood vessels of the brain (thrombotic stroke).

2. Hemorrhagic Stroke: This kind of stroke arises when a blood vessel in the brain bursts or leaks, resulting in bleeding into the surrounding brain tissue.  Strokes that are hemorrhagic are more severe but less frequent than ischemic strokes. Hemorrhagic strokes can be classified into two primary subtypes: intracerebral hemorrhage (bleeding inside the brain) and subarachnoid hemorrhage (bleeding in the space between the brain and the skull).

The signs and symptoms of a stroke might vary depending on the part of the brain that is affected, but frequent ones include:

- Suddenly feeling weak or numb, frequently on one side of the body.
- Sudden difficulty speaking or confusion.
- A sudden visual issue, such as double or blurry vision.
- An unexpectedly severe headache.
- A sudden inability to walk, dizziness, loss of balance, or lack of coordination.

If a stroke is suspected, it is crucial to seek immediate medical assistance since prompt intervention can lessen brain damage and improve the outcome. To remember stroke warning symptoms, people frequently use the abbreviation FAST:

- F: Face drooping
- A: Arm weakness
- S: Speech difficulty
- T: Time to call emergency services

High blood pressure, smoking, diabetes, obesity, high cholesterol, a family history of stroke, and age (the risk rises with age) are all stroke risk factors. Rehabilitation and therapy can assist persons who have had a stroke recover from their symptoms, and lifestyle modifications and pharmacological interventions can prevent the chance of stroke.
