Predicting continued dizziness after an acute peripheral vestibular disorder

Area of Science:

• Neurology
• Psychology

Background:

• Acute peripheral vestibular disorders, like vestibular neuritis (VN) and benign paroxysmal positional vertigo (BPPV), typically resolve within weeks.
• However, some individuals develop persistent dizziness, suggesting underlying psychological factors may play a role.

Purpose of the Study:

• To identify predictors of ongoing dizziness 3 months after an acute peripheral vestibular disorder.
• To investigate the role of fear of bodily sensations and anxiety cognitions in the development of persistent psychogenic dizziness.

Main Methods:

• A prospective longitudinal study involving 43 patients with vestibular neuritis or benign paroxysmal positional vertigo.
• Assessment of fear of bodily sensations, anxiety cognitions, and mental disorders at admission and 3 months later.

Main Results:

• The interaction between fear of bodily sensations within 2 weeks of admission and the type of vestibular disorder predicted 21% of the variance in dizziness complaints at 3 months.
• This prediction was significant for vestibular neuritis but not for benign paroxysmal positional vertigo.
• The effect was attributed to the initial severity of dizziness, which differed between the two conditions.

Conclusions:

• Fear of bodily sensations is relevant for persistent psychogenic dizziness only when interacting with the initial severity of the organic vestibular episode.
• Screening patients with vestibular disorders for at-risk status and providing psychological support is crucial for preventing chronic psychogenic dizziness.
