تعريف ومعنى "stroke"

What is a "stroke"?

A stroke occurs when part of the brain does not receive enough oxygen and nutrients because the blood supply is cut off or reduced. This can happen because of a blockage in an artery, known as an ischemic stroke, or the bursting of a blood vessel, known as a hemorrhagic stroke. Symptoms of a stroke include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body, difficulty speaking or understanding speech, confusion, trouble walking, dizziness, and an intense headache. Immediate medical attention is critical for treating a stroke, as early treatment can minimize brain damage and improve outcomes. Treatment may involve medications, procedures to remove blood clots, and rehabilitation to regain lost functions.

Strokes can vary in length, angle, and shape, contributing to the complexity and beauty of the characters in these writing systems. Proper stroke usage is essential for learning and writing these languages accurately.
