Preceding Benign Paroxysmal Positional Vertigo as a Trigger for Persistent Postural-Perceptual Dizziness: Which...

Area of Science:

• Neurology
• Otolaryngology
• Vestibular Disorders

Background:

• Persistent Postural-Perceptual Dizziness (PPPD) can be primary or secondary to an organic disorder (s-PPPD).
• Benign Positional Paroxysmal Vertigo (BPPV) is a common somatic trigger for s-PPPD.
• Identifying predictive factors for PPPD development after BPPV is clinically important.

Purpose of the Study:

• To identify clinical predictors of PPPD development in patients with BPPV as a trigger.
• To compare clinical features between patients who developed PPPD after BPPV and those who did not.

Main Methods:

• Retrospective case review of 126 patients diagnosed with PPPD.
• Comparison of 51 s-PPPD patients with BPPV trigger against a control group with BPPV but no PPPD.
• Evaluation of age, sex, latency to diagnosis, BPPV recurrence, and migraine presence.

Main Results:

• Patients who developed PPPD secondary to BPPV were significantly older on average.
• A longer latency period between BPPV onset and final diagnosis was observed in the s-PPPD group.
• No significant differences were found in sex, BPPV recurrence rates, or migraine prevalence.

Conclusions:

• Advanced age and prolonged latency to BPPV diagnosis are key predictors for developing PPPD.
• These findings underscore the importance of prompt BPPV diagnosis and management, especially in older adults.
• Early intervention may help prevent the progression from BPPV to PPPD.
