Vestibular Disease.

This research article provides an overview of the vestibular system function related to maintaining balance and orientation during rest and movements, as well as the effects of disorders affecting the system. This involves a review of the functional anatomy, vestibular disease, clinical signs, and examples of conditions impacting the vestibular system.

Overview of the Vestibular System

• The vestibular system (VS) is a sensory system essential for maintaining balance and orientation of body parts in a state of rest and during movement. It oversees the position of the eyes, neck, trunk, and limbs.
• Two important reflexes play an essential role in maintaining balance. They are vestibulo-ocular reflexes, responsible for coordinating eye and head movements, and vestibulospinal reflexes responsible for body and limb orientation.

Reflexes Involved in Maintaining Balance

• The study identifies that these reflexes are an interaction of peripheral and central components of the vestibular system. These components form a complex network that also integrates the functions of other reflexes to produce a coordinated output for balancing.

Clinical Implications

• The article discusses the possible diseases or disorders of the vestibular system. Most of these conditions result in ipsilateral neurologic deficits, meaning the disease side and the affected side are the same. For example, a right side disorder would cause problems on the right side of the body.
• There are a few exceptions to this rule, where the disorder may present contralateral signs; that is, a disorder on one side can manifest symptoms on the opposite side of the body.

Review of Functional Anatomy, Vestibular Disease and Clinical Signs

• The paper provides a concise review of the functional anatomy of the vestibular system, looking at its detailed structure and how it performs the essential task of maintaining balance.
• It further describes different vestibular diseases, their manifestation and possible causes.
• The paper also explores the different clinical signs that clinicians can use to detect if the vestibular system is affected or not.
