Brain Blood Vessel Narrowing And Its Symptoms

Brain blood vessels are divided into multiple branches. The internal carotid artery is part of the anterior circulation, while the posterior circulation includes the vertebral and basilar arteries, which supply different regions of the brain. When blood vessels in the brain become narrowed, it can lead to a variety of symptoms depending on the affected area. For example, narrowing in the anterior circulation, such as in the internal carotid artery or middle cerebral artery, can cause symptoms like hemiplegia (paralysis on one side of the body), hemianopia (loss of vision in one half of the visual field), and aphasia (difficulty with speech or language).

Posterior Circulation Symptoms

Narrowing in the posterior circulation, particularly in the vertebral or basilar arteries, can lead to symptoms such as dizziness, loss of balance, and unsteady gait. Patients may also experience difficulty swallowing, known as dysphagia, or coughing while drinking fluids. These symptoms occur because the affected blood vessels are responsible for supplying crucial areas of the brain involved in balance, coordination, and basic motor functions.

Importance Of Early Diagnosis

The symptoms of cerebral vascular disease can vary widely, and the presence of any of the above signs should be taken seriously. It is crucial to seek immediate medical attention if any of these symptoms occur, even if they seem temporary. A healthcare professional can evaluate the condition, perform necessary tests, and determine the appropriate course of action to prevent potential complications such as stroke.
