ABSTRACT
This report describes the objectives, design, and methods of the Munich Diagnostic and Predictor Study of Dizziness, a prospective study investigating diagnostic subgroups, correlates, and predictors of dizziness that is not sufficiently explained medically but clearly related to a psychiatric disorder. All patients presenting at the Integrated Centre for Research and Treatment of Vertigo, Balance and Ocular Motor Disorders at the University Hospital Großhadern in Munich, Germany, are investigated during their first-time visit. The study consists of a baseline and two follow-up assessment points at 6 and 12 months. At the baseline assessment point, all participants complete self-rated questionnaires concerning dizziness, depression, anxiety, dissociative and traumatic experiences, somatization, body sensations and perception, cognitions, attachment, personality, quality of life and experiences with the health care system. Additionally, a structured clinical interview is conducted to assess mental disorders. Then, the neurologists complete questionnaires regarding the subjective doctor-patient relationship and to document the somatic diagnoses and results. The follow-up measurements consist of self-rated questionnaires. This study aims to improve the diagnosis and treatment of patients who suffer from dizziness related to a psychiatric disorder and who are often severely impaired in their working and daily lives.
