Patients who experience chronic dizziness are considered to be difficult to treat. Persisting symptoms of vertigo can be caused by recurrent organic as well as a variety of psychogenic factors, the latter usually being part of anxiety and depression disorders. Psychotherapeutic interventions can achieve improvements, the effects, however, in general do not persist over a longer time. The purpose of this study is to investigate the long-term effects of a symptom-related indoor treatment including neurotological and psychotherapeutic approaches as well as vestibular and balance rehabilitation. 23 indoor patients 16 male patients and 7 female., mean age 56.6 years (SD 12) with chronic vestibular symptoms (longer than six months), who were treated with neurotological counseling, psychotherapy, vestibular and balance rehabilitation and-if necessary-antidepressant drugs during a lengthy hospital stay [average 40 days (SD 14)], were re-examined. After a time period of at least one year (average 32 months; SD 15) they were asked to answer a questionnaire concerning post-therapeutic status of dizziness, symptoms and coping strategies as well as the Hospital Anxiety and Depression Score (HADS D). 18 of 23 patients (78%) reported a sustained reduction in their vertiginous symptoms. Four patients did not report a persistent improvement and one even got worse. Patients with a chronic form of dizziness can improve through a coordinated neurotologic and psychotherapeutic approach including vestibular and balance rehabilitation.

Background: Vertigo and dizziness are often not fully explained by an organic illness, but instead are related to psychiatric disorders. This study aimed to evaluate psychiatric comorbidity and assess psychosocial impairment in a large sample of patients with a wide range of unselected organic and non-organic (ie, medically unexplained) vertigo/dizziness syndromes., Methods: This cross-sectional study involved a sample of 547 patients recruited from a specialised interdisciplinary treatment centre for vertigo/dizziness. Diagnostic evaluation included standardised neurological examinations, structured clinical interview for major mental disorders (SCID-I) and self-report questionnaires regarding dizziness, depression, anxiety, somatisation and quality of life., Results: Neurological diagnostic workup revealed organic and non-organic vertigo/dizziness in 80.8% and 19.2% of patients, respectively. In 48.8% of patients, SCID-I led to the diagnosis of a current psychiatric disorder, most frequently anxiety/phobic, somatoform and affective disorders. In the organic vertigo/dizziness group, 42.5% of patients, particularly those with vestibular paroxysmia or vestibular migraine, had a current psychiatric comorbidity. Patients with psychiatric comorbidity reported more vertigo-related handicaps, more depressive, anxiety and somatisation symptoms, and lower psychological quality of life compared with patients without psychiatric comorbidity., Conclusions: Almost half of patients with vertigo/dizziness suffer from a psychiatric comorbidity. These patients show more severe psychosocial impairment compared with patients without psychiatric disorders. The worst combination, in terms of vertigo-related handicaps, is having non-organic vertigo/dizziness and psychiatric comorbidity. This phenomenon should be considered when diagnosing and treating vertigo/dizziness in the early stages of the disease., (Published by the BMJ Publishing Group Limited.

Objectives: The objective of this study was to assess the objectivity, cross-cultural validity, and convergent validity of the Vestibular Activities and Participation (VAP) questionnaire among four countries, Germany, United States, Jordan, and Saudi Arabia., Study Design and Setting: This was a cross-sectional study conducted in four specialized outpatient dizziness clinics in Germany, United States, Jordan, and Saudi Arabia., Results: A total of 453 participants were included in the study. The Rasch analysis revealed two separate subscales. Subscale 1 items included focusing attention, lying down, standing, bending, lifting and carrying objects, and sports. Subscale 2 items included walking long distances, climbing, running, moving around within buildings other than home, using transportation, and driving. The Pearson product-moment correlation between the Dizziness Handicap Inventory and the summary score of the VAP subscale 1 was 0.66 and was 0.64 for subscale 2., Conclusion: Owing to its shortness and intercultural adaptability, the new two-scale version of the VAP questionnaire lends itself to clinical practice and research across countries to estimate the effect of vertigo and dizziness on activity limitation and participation restrictions. Psychometrically sound summary scores can be calculated. More extended versions of the VAP can be used for comprehensive clinical assessment where summary scores are not needed or a more detailed documentation is warranted., (Copyright © 2015 Elsevier Inc.

The Vertigo Handicap Questionnaire (VHQ) by Yardley (1992) assesses physical and psychosocial impairments of vertigo or dizziness. Our study examines the structure, reliability, and aspects of validity of the German version of the VHQ. 98 vestibular vertigo syndromes vs. 90 patients with somatoform vertigo and dizziness were evaluated with the VHQ, symptom severity (VSS), distress (GSI), anxiety and depression (HADS), catastrophizing beliefs (ACQ), fear of body sensations (BSQ), and quality of life (SF-36). For diagnostic classification detailed clinical neurological, neuro-otological and psychosomatic testing were conducted. Principal components analysis identified two factors, which could be confirmed by confirmatory factor analyses: 'handicapped activity'(VHQ-ACT) and 'anxiety' (VHQ-ANX). The VHQ had good internal consistency (Cronbach's alpha: 0.92). Test-retest reliability was r = 0.80. We noted close relations between the VHQ, the VSS and measures of emotional distress as aspects of good construct validity. Together with the VSS, the VHQ completes a comprehensive diagnostic screening tool for vertigo or dizziness., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: Dizziness has a clear impact on quality of life of patients. Standardized instruments such as the "Dizziness Handicap Inventory" (DHI) help clinicians assess this impact systematically. The purpose of this study was to analyse the psychometric quality of a German version of the DHI., Methods: One hundred and five patients with dizziness as their primary complaint have completed the DHI and undergone vestibular examination. The structure of the DHI was determined with a factor analysis, a principal component analysis with a Varimax rotation. To evaluate the reliability, internal consistency (Cronbach's alpha) was estimated., Results: A three-factor solution was extracted. The factors obtained from the German version of the DHI related to (1) activity and participation limitations (2) emotional problems and (3) motion sensitivity in everyday life of patients. Overall, there was a close correspondence of the factors of the German and the original version. The correlation analysis indicated a close relationship between the DHI-scores and the frequency of dizziness attacks., Conclusion: The German version of the DHI exhibited a multidimensional structure and good psychometric quality to assess the impact of dizziness in every day life.

Objective: To translate the Dizziness Handicap Inventory into German (DHI-G) and investigate reliability, assess the association between selected items of the University of California Los Angeles Dizziness Questionnaire and the DHI-G, and compare the scores of patients and healthy participants., Study Design: Cross-sectional design., Setting: Tertiary center for vertigo, dizziness, or balance disorders., Patients: One hundred forty-one patients with vertigo, dizziness, and unsteadiness associated with a vestibular disorder, with a mean age (standard deviation) of 51.5 (13.2) years, and 52 healthy individuals participated., Interventions: Fourteen patients participated in the cognitive debriefing; 127 patients completed the questionnaires once or twice within 1 week., Main Outcome Measures: The DHI-G assesses disability caused by dizziness and unsteadiness; the items of the University of California Los Angeles Dizziness Questionnaire assess dizziness and impact on everyday activities. Internal consistency was estimated using Cronbach alpha, reproducibility by calculating Bland-Altman limits of agreement and intraclass correlation coefficients. Associations were estimated by Spearman correlation coefficients., Results: Patients filled out the DHI-G without problem and found that their self-perceived disabilities were mostly included. Cronbach alpha values for the DHI-G and the functional, physical, and emotional subscales were 0.90, 0.80, 0.71, and 0.82, respectively. The limits of agreement were +/-12.4 points for the total scale (maximum, 100 points). Intraclass correlation coefficients ranged from 0.90 to 0.95. The DHI-G correlated moderately with the question assessing functional disability (0.56) and fairly with the questions quantifying dizziness (0.43, 0.35). The DHI-G discriminated significantly between healthy participants and patients., Conclusion: The DHI-G demonstrated good reliability and is recommended as a measure of disability in patients with dizziness and unsteadiness.
