PurposeThe present study was undertaken to investigate orthostatic hypotension and psychiatric comorbidity with anxiety and depression in dizzy patients.Materials and methodsSixty-three patients with nonspecific dizziness and 27 volunteer subjects were evaluated with the head-up tilt test (HUTT) and the Standardized Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I.ResultsOrthostatic hypotension was induced by HUTT in 44% of patients and in 15% of volunteers (P = .0082); we found that the incidence of anxiety and depression was significantly higher (P < .05) in patients with nonspecific dizziness than in controls. Orthostatic hypotension was related to age but not to antihypertensive therapy and sex. Dizziness during the HUTT was reported by 49% of patients and 33% of volunteers (P = .2469). Among patients, dizziness was found to be related to sex (female) and anxiety. A correlation between dizziness and anxiety was also present in volunteers. Head-up tilt test induced vasovagal reactions in 2 volunteers.ConclusionsOrthostatic hypotension is present in a high percentage of patients with orthostatic dizziness, and anxiety and depression are an important factor in the onset of dizziness. A high percentage of abnormal responses in volunteer subjects seems to indicate that the HUTT is not indicated for routine use.
