“…Possible explanation may be the persistence of debris in the canal, insuYcient to provoke noticeable positional nystagmus [16], an utricular dysfunction [17], an undiagnosed coexisting vestibular disorder or an incomplete central adaptation [18].…”

Even after successful repositioning maneuvers for benign paroxysmal positional vertigo (BPPV), some patients report dizziness lasting for a certain period afterwards. We studied the prevalence and clinical factors associated with residual dizziness in a sample of elderly patients. Sixty outpatients over 65 years of age, affected by idiopathic BPPV were recruited; the exclusion criterion was a history of previous episodes of vertigo, including positional. The patients were asked to describe their self-perceived anxiety for vertigo on a Visual Analogue Scale (VAS) and successively treated with appropriate maneuvers till resolution of nystagmus. Data concerning the demographic and clinical features of BPPV were collected. Patients were followed until complete resolution of subjective dizziness and imbalance without positional nystagmus. Data about residual dizziness were collected from the second day from resolution of BPPV. Clinical and demographic factors related to residual dizziness were analyzed. Twenty-two subjects (37%) reported residual dizziness. In these subjects, the mean duration of residual dizziness was 13.4 ± 7.5 days. No association was observed between residual dizziness and gender, involved canal and the number of repositioning maneuvers before resolution. On the other hand, age older than 72 years, symptom duration greater than 9 days and VAS scale for anxiety greater than 10/100 were associated with an increased risk of residual dizziness. The odds ratio were respectively 6.5 (age-residual dizziness, Confidence Interval 95%), 6.5 (duration of vertigo-residual dizziness, Confidence Interval 95%) and 15.5 (anxiety levels-residual dizziness, Confidence Interval 95%). Longer symptom duration before diagnosis was associated with higher anxiety levels. The results underline the necessity for an early and correct diagnosis of BPPV, especially in the elderly.

Objective: To establish a possible causal factor for residual dizziness (RD) after successful repositioning maneuvers in patients with benign paroxysmal positional vertigo (BPPV). Materials and Method: Ninety consecutive patients with idiopathic BPPV were treated with repositioning maneuvers, and the rate of RD was assessed as well as clinical data. Posturography and assessment of anxiety levels were performed on patients reporting RD. Results were compared with a control group of BPPV patients of the sample after repositioning maneuvers and without RD. Results: Twenty-eight subjects (31.1%) reported RD on the second day after successful repositioning maneuvers. The mean duration of RD was 11.6 ± 3.9 days. Patients with RD presented a higher duration of BPPV (14.1 vs. 10.9 days, p = 0.01). A correlation was demonstrated between the duration of BPPV and duration of RD (p < 0.01). Subjects with RD presented increased body sways, above all in eyes-closed conditions. Conclusion: RD is mainly correlated with duration of vertigo in BPPV patients. Anxiety was demonstrated to play a role in increased body sways.
