Clinical features and outcome predictors in benign paroxysmal positional vertigo and its variant: Perspective in a primary care neurology clinic.

This article focuses on the clinical characteristics and treatment outcomes of benign paroxysmal positional vertigo (BPPV) and its variant, light cupula syndrome, in a primary care neurology setting. Among 1126 patients presenting with dizziness or vertigo, 27.4% were diagnosed with BPPV or its variant, with the posterior canal (PC) subtype being most common (59.4%), followed by geotropic and apogeotropic horizontal canal (HC) types. The study found that the proportion of PC subtype increased with longer symptom duration, while patients exhibiting persistent positional nystagmus (lasting ≥1 minute) required significantly more canalith repositioning procedures (CRPs) and were more refractory to treatment than those with transient nystagmus. These findings suggest that in primary care, symptom duration and nystagmus persistence are important factors influencing BPPV subtype distribution and treatment responsiveness, highlighting the need for routine screening and tailored management strategies.
