Abstract
The normal vestibular system may be adversely affected by environmental challenges
which have characteristics that are unfamiliar or ambiguous in the patterns of sensory
stimulation they provide. A disordered vestibular system lends susceptibility even
to quotidian environmental experiences as the sufferer becomes dependent on potentially
misleading, nonvestibular sensory stimuli. In both cases, the sequelae may be vertigo,
incoordination, imbalance, and unpleasant autonomic responses. Common environmental
motion conditions include visual vertigo, motion sickness, and motorists' disorientation.
The core therapy for visual vertigo, motion sickness, and drivers' disorientation
is progressive desensitization within a cognitive framework of reassurance and explanation,
plus anxiolytic tactics and autogenic control of autonomic symptoms.
