  • Title: Which comes first? Psychogenic dizziness versus otogenic anxiety.
    Author: Staab JP, Ruckenstein MJ.
    Journal: Laryngoscope; 2003 Oct; 113(10):1714-8. PubMed ID: 14520095.
    Abstract:
    OBJECTIVE To investigate the hypotheses that physical neurotologic conditions may trigger anxiety disorders (otogenic pattern of illness), that psychiatric disorders may produce dizziness (psychogenic pattern), and that risk factors for these syndromes may be identified. STUDY DESIGN Retrospective review of all patients (N = 132) treated at a tertiary care balance center from 1998 to 2002 for psychogenic dizziness with or without physical neurotologic illnesses. METHODS All patients underwent comprehensive neurotologic and psychiatric evaluations with attention to the longitudinal course of symptoms and risk factors for psychopathology. Patients were grouped according to the condition first causing dizziness. Risk factors were compared across groups. RESULTS Three equally prevalent patterns of illness were found: anxiety disorders as the sole cause of dizziness (33% of cases), neurotologic conditions exacerbating preexisting psychiatric disorders (34%), and neurotologic conditions triggering new anxiety or depressive disorders (33%). Panic disorder and agoraphobia were significantly more prevalent than less severe phobias in the first two groups, whereas the opposite pattern existed in the third group (P <.0001). More patients in the first two groups had risk factors for anxiety disorders (P <.05). Depression was not a primary cause of dizziness in any patient. Vestibular neuronitis, benign paroxysmal positional vertigo, and migraine were the most common neurotologic conditions. CONCLUSIONS These data support the hypothesis that physical neurotologic conditions may trigger psychopathology as often as primary anxiety disorders cause dizziness. A third pattern appears to be equally common wherein physical neurotologic conditions exacerbate preexisting psychiatric illnesses. Individuals at risk for anxiety disorders may be more likely to have primary psychopathology.
