Periaqueductal grey matter lesions can lead to various symptoms and complications, affecting an individual’s quality of life. In this guide, we’ll break down what these lesions are, their causes, symptoms, diagnostic tests, treatments, medications, surgeries, preventions, and when to seek medical help. We’ll keep the language simple and clear to ensure easy understanding.
The periaqueductal grey matter is a part of the brain stem responsible for many important functions, including pain modulation, defensive behavior, and autonomic responses. Lesions in this area can disrupt these functions, leading to a range of symptoms.
