Posterior circulation strokes occur when blood flow to the back part of the brain is disrupted. This area includes vital structures like the brainstem, cerebellum, and occipital lobes, which are essential for balance, coordination, and vision. Symptoms can include dizziness, double vision, and difficulty walking. These strokes can be caused by various factors, such as blood clots, narrowed arteries, or even a tear in a blood vessel. Early recognition and treatment are crucial, as they can lead to serious complications. Understanding the signs and seeking immediate medical help can improve outcomes for those affected.
