Hi All,
Last night I got onto Medline and decided to have a good look at the evidence out there with regards to anxiety and vestibular disorders. If I had a dollar for everytime a professional/friend told me, "your anxiety is causing your dizziness/vertigo", I'd be rich. So I decided to see what was out there to support the opposite - that vestibular disorders fuel and drive the anxiety. At least that's how I feel it works with me and I know many of you feel the same.
This one was the most interesting:
Dizziness and panic disorder: a review of the association between vestibular dysfunction and anxiety.Simon et al.
Annals of Clinical Psychiatry1998.
Quote:
There are 3 models proposed: Psychosomatic model: describes vestibular dysfunction as a consequence of anxiety. Hyperventilation and hyperarousal increase vestibulo-ocular reflex sensitivity, even among normals who hyperventilate. No studies have examined vestibular dysfunction during a panic attack. Somatopsychic model: proposes that cases of panic disorder are triggered by misinterpreted internal stimuli (eg. stimuli from vestibuar dysfunction), that are interpreted as signifying imminent physical danger. Heightened sensitivity to vestibular sensations leads to increased anxiety and, through conditioning, drives the development of panic disorder. Network alarm theory: derives from pharmacological challenge studies and other laboratory assessments of panic that suggest involvement of noradrenergic, serotonergic, and other connected neuronal systems. According to this theory, panic can be triggered by stimuli that set off a false alarm via afferents to the locus ceruleus, which then triggers the neuronal network. This network is thought to mediate anxiety and includes limbic, midbrain and prefrontal areas. Vestibular dysfunction in the setting of increased locus ceruleus sensitivity may be one potential trigger. The network alarm model contributes to a neuropsychiatric explanation for the somatopsychic model.

So there you have it, at least two models from the literature that support lab or other inner ear problems potentially driving anxiety and resultant panic attacks. Might help next time you guys visit a "specialist" and need something to back up your views.
