1. Focal Lesions
Focal lesions in the vestibular nuclei, brainstem, thalamus and cortex can cause significant postural control impairments, dizziness and functional mobility dysfunction. These lesions cause impairments that are based upon the anatomy that they affect, so knowing the underlying anatomy helps to identify the impairment. In this chapter, a few types of vestibular impairment are discussed, including information that is helpful for differential diagnosis.
2. Traumatic Brain Injury and the Central Vestibular System
Traumatic brain injury can affect the vestibular system, either by direct trauma to the skull, causing fractures, by direct trauma/hemorrhagic lesions, or by the more diffuse dysfunction that happens during concussion. The accompanying sequelae of signs and symptoms can make vestibular impairment difficult to discern. This chapter reviews TBI as it relates to the vestibular system and reviews some ways in which the vestibular system is affected by TBI.
3. Vestibular Migraine
Vestibular migraine is a common cause of dizziness. Due to the diffuse nature of migraine symptoms, it is challenging to identify vestibular migraine. This chapter will review the pathophysiology and central structures affected by migraine, the diagnostic criteria for vestibular migraine, and management considerations.
4. Persistent Postural-Perceptual Dizziness
Persistent postural-perceptual dizziness occurs due to changes in the brain that result in chronic symptoms of disequilibrium and dizziness. Psychologic conditions play a role in the development of PPPD. A clear understanding of the pathophysiology and diagnostic criteria for PPPD will help in managing this challenging diagnosis.
5. General Guidelines, Efficacy Research and Summary
The conclusion of this course focuses on the general oculomotor changes that occur with vestibular migraine and a review of the management guidelines for those with central vestibular disorders. A brief review of the rehabilitation efficacy research in central vestibular disorders will also be presented, followed by a summary of this course.
