Multimodal treatment of persistent postural-perceptual dizziness.

Abstract

BackgroundPersistent postural–perceptual dizziness (PPPD) is a chronic disorder with fluctuating symptoms of dizziness, unsteadiness, or vertigo for at least three months. Its pathophysiological mechanisms give theoretical support for the use of multimodal treatment. However, there are different therapeutic programs and principles available, and their clinical effectiveness remains elusive.MethodsA database of patients who participated in a day care multimodal treatment program was analyzed regarding the therapeutic effects on PPPD. Vertigo Severity Scale (VSS) and Hospital Anxiety and Depression Scale (HADS) were assessed before and 6 months after therapy.ResultsOf a total of 657 patients treated with a tertiary care multimodal treatment program, 46.4% met the criteria for PPPD. PPPD patients were younger than patients with somatic diagnoses and complained more distress due to dizziness. 63.6% completed the follow‐up questionnaire. All patients showed significant changes in VSS and HADS anxiety, but the PPPD patients generally showed a tendency to improve more than the patients with somatic diagnoses. The change in the autonomic–anxiety subscore of VSS only reached statistical significance when comparing PPPD with somatic diagnoses (p = .002).ConclusionsTherapeutic principles comprise cognitive–behavioral therapy, vestibular rehabilitation exercises, and serotonergic medication. However, large‐scale, randomized, controlled trials are still missing. Follow‐up observations after multimodal interdisciplinary therapy reveal an improvement in symptoms in most patients with chronic dizziness. The study was not designed to detect diagnosis‐specific effects, but patients with PPPD and patients with other vestibular disorders benefit from multimodal therapies.
