An ischemic stroke occurs when blood supply to the brain is cut off.
Understanding Ischemic Stroke
An ischemic stroke happens when a blood clot blocks an artery leading to the brain, reducing or stopping blood flow. This lack of blood deprives brain cells of oxygen and nutrients, leading to damage.
- Cause: According to provided information, An ischemic stroke occurs when a blood clot, known as a thrombus, blocks or plugs an artery leading to the brain. A blood clot often forms in arteries damaged by a buildup of plaques, known as atherosclerosis.
Formation of Blood Clots
Blood clots often form in arteries damaged by atherosclerosis. Atherosclerosis is a condition where plaque builds up inside the arteries. This buildup narrows the arteries and makes it easier for blood clots to form. These clots can then travel to the brain and block blood flow, leading to an ischemic stroke.
Impact on the Brain
When an artery to the brain is blocked, brain cells begin to die within minutes. This can lead to:
- Loss of motor skills
- Speech difficulties
- Memory problems
- Other neurological deficits, depending on the area of the brain affected
