- dAlcohol intoxication affects the vestibular system and balance control in many ways. We have investigated how acute, moderate (blood alcohol concentrations of 0.06 +/- 0.01%), and high (0.10 +0.02%) alcohol intoxication affects the ability to perceive the visual horizontal and vertical and the visual field dependence measured with the rod and frame tests in 24 healthy participants. Alcohol ingestion impaired the ability to use gravitational vestibular cues when determining the visual vertical and horizontal, and caused increased visual field dependence. With conflicting gravitational and visual information, alcohol seems to promote a reweighting in balance control from a vestibular to a more visual dependency. Furthermore, the results indicate that alcohol intoxication at these levels start instigating a decompensation of minute subdinical vestibular asymmetries.

Journal article (peer-reviewed)abstract
- Benign paroxysmal positional vertigo presents with brief, episodic, positioning-provoked vertigo and characteristic findings on Dix-Hallpike and other positional tests. This article is based on a systematic review of the literature and describes epidemiology, etiology, pathogenesis, diagnostic positional tests and treatment using canalith repositioning, liberatory and 360 degrees rotation manoeuvres. Diagnostic pitfalls, mastoid vibration, postmanoeuvre activity restriction and the ideal number of repositioning manoeuvres per treatment session are discussed.

One-year follow-up of cognitive behavioral therapy for phobic postural vertigo

- Background Phobic postural vertigo is characterized by dizziness in standing and walking despite normal clinical balance tests. Patients sometimes exhibit anxiety reactions and avoidance behavior to specific stimuli. Different treatments are possible for PPV, including vestibular rehabilitation exercises, pharmacological treatment, and cognitive behavioral therapy. We recently reported significant benefits of cognitive behavioural therapy for patients with phobic postural vertigo. This study presents the results of a one-year follow-up of these patients. Methods Swedish translations of the following questionnaires were administered: (Dizziness Handicap Inventory, Vertigo Symptom Scale, Vertigo Handicap Questionnaire, and Hospital Anxiety and Depression Scale) were administered to 20 patients (9 men and 11 women; mean age 43 years, range 23-59 years) one year after completion of cognitive behavioral therapy. Results Test results were similar to those obtained before treatment, showing that no significant treatment effects remained. Conclusion Cognitive behavioral therapy has a limited long-term effect on phobic postural vertigo. This condition is more difficult to treat than panic disorder with agoraphobia. Vestibular rehabilitation exercises and pharmacological treatment might be the necessary components of treatment.

Reduced postural differences between phobic postural vertigo patients and healthy subjects during a postural threat.

- Phobic postural vertigo is characterized by subjective imbalance and dizziness while standing or walking, despite normal values for clinical balance tests. Patients with phobic postural vertigo exhibit an increased high-frequency sway in posturographic tests. Their postural sway, however, becomes similar to the sway of healthy subjects during difficult balance tasks. Posturographic recordings of 30 s of quiet stance was compared to recordings of 30 s of quiet stance during a postural threat, which consisted of the knowledge of forthcoming vibratory calf muscle stimulation, in 37 consecutive patients with phobic postural vertigo and 24 healthy subjects. During quiet stance without the threat of forthcoming vibratory stimulation, patients with phobic postural vertigo exhibited a postural sway containing significantly more high-frequency sway than the healthy subjects. During the quiet stance with forthcoming vibratory stimulation, i.e., anticipation of a postural threat, the significant differences between groups disappeared for all variables except sagittal high-frequency sway. During postural threat, healthy subjects seemed to adopt a postural strategy that was similar to that exhibited by phobic postural vertigo patients. The lack of additional effects facing a postural threat among phobic postural vertigo patients may be due to an already maximized postural adaptation. Deviant postural reactions among patients with phobic postural vertigo may be considered as an avoidant postural response due to a constant fear of losing postural control.

Journal article (peer-reviewed)abstract
- In balance clinic practice, phobic postural vertigo is a term used to define a population with dizziness and avoidance behavior often as a consequence of a vestibular disorder. It has been described as the most common form of dizziness in middle aged patients in dizziness units. Anxiety disorders are common among patients with vestibular disorders. Cognitive-behavioral therapy is an effective treatment for anxiety disorders, and vestibular rehabilitation exercises are effective for vestibular disorders. This study compared the effect of additional cognitive-behavioral therapy for a population with phobic postural vertigo with the effect of self-administered vestibular rehabilitation exercises. 39 patients were recruited from a population referred for otoneurological investigation. Treatment effects were evaluated with the Dizziness Handicap Inventory, Vertigo Symptom Scale, Vertigo Handicap Questionnaire, and Hospital Anxiety and Depression Scale. All patients had a self treatment intervention based on education about the condition and recommendation of self exposure by vestibular rehabilitation exercises. Every second patient included was offered additional cognitive behavioral therapy. Fifteen patients with self treatment and 16 patients with cognitive-behavioral treatment completed the study. There was significantly larger effect in the group who received cognitive behavioral therapy than in the self treatment group in Vertigo Handicap Questionnaire and the Hospital Anxiety and Depression scale and its subscales. Cognitive-behavioral therapy has an additional effect as treatment for a population with phobic postural vertigo. A multidisciplinary approach including medical treatment, cognitive-behavioral therapy and physiotherapy is suggested.

Mondini-like malformation mimicking otosclerosis and superior semicircular canal dehiscence.
- 2006

In: Journal of Laryngology and Otology. - 1748-5460. ; 120:5, s. 419-422
-
Journal article (peer-reviewed)abstract
- In 2003, it was reported that superior semicircular canal dehiscence can mimic otosclerosis because of low-frequency bone conduction hearing gain and dissipation of air-conducted acoustic energy through the dehiscence. We report the case of a 17-year-old girl with left-sided combined hearing loss thought to be due to otosclerosis. Bone conduction thresholds were -10 dB at 250 and 500 Hz and she had a 40 dB air bone gap at 250 Hz. When a tuning fork was placed at her ankle she heard it in her left ear. Acoustic reflexes and vestibular evoked myogenic potentials could be elicited bilaterally. Imaging of the temporal bones showed no otosclerosis, superior semicircular canal dehiscence or large vestibular aqueduct, but a left-sided, Mondini-like dysplasia of the cochlea with a modiolar deficiency could be seen. Mondini-like cochlear dysplasia should be added to the causes of inner-ear conductive hearing loss.
