Intracranial atherosclerosis

Intracranial atherosclerosis is a condition where the arteries inside the skull become narrowed or hardened due to the buildup of fatty deposits, cholesterol, and other materials. This thickening can reduce or block blood flow to the brain, increasing the risk of strokes or mini-strokes. It often develops gradually and may not cause symptoms until significant blockage occurs. Factors like high blood pressure, smoking, high cholesterol, and diabetes can contribute to its development. Managing these risk factors and seeking medical care are essential to prevent serious complications related to intracranial atherosclerosis.
