Peripheral Vestibulospinal Tract Lesions can cause a range of issues affecting balance and coordination. In this guide, we’ll break down what these lesions are, their causes, symptoms, diagnosis methods, and available treatments, including both non-pharmacological options and medications. Additionally, we’ll touch on surgeries, prevention strategies, and when it’s crucial to seek medical attention.
The peripheral vestibulospinal tract is a pathway in the nervous system responsible for transmitting signals related to balance and coordination from the inner ear (vestibular system) to the spinal cord. Lesions in this tract can disrupt these signals, leading to various symptoms.
