G45.2: Multiple and bilateral precerebral artery syndromes

Multiple and bilateral precerebral artery syndromes is a medical condition where certain arteries that supply blood to the brain are affected. Specifically, it involves the arteries before they penetrate the cerebrum, or the large part of the brain which includes areas that control movements, sensations, speech, thinking, and memory. "Multiple" and "bilateral" refers to the condition affecting several arteries and both sides of the body. Common symptoms include transient attacks of neurological dysfunction, such as temporary blindness in one eye, difficulty speaking, or paralysis on one side of the body. These symptoms are often brief and reversible, usually lasting less than 24 hours. These attacks, known as transient ischemic attacks, can indicate a serious risk of a future stroke. The condition is commonly caused by a clot or debris blocking blood flow in the arteries, often due to medical conditions that cause blood clots or unhealthy arteries, such as heart disease, diabetes or high cholesterol. It is not contagious or hereditary but risk factors include age, smoking, and unhealthy lifestyle choices. The disease can progress over time if not managed properly, potentially leading to more serious conditions like stroke.
