| Popis: | The aim of this study was to evaluate clinical and neurophysiological characteristics of Persistent postural-perceptual dizziness (PPPD) in a tertiary vertigo clinic. This was a cross-sectional study that included consecutive patients examined in the Vertigo clinic of the University Hospital Center Zagreb, Croatia. The following data were extracted from the electronic hospital records: age, sex, the duration of symptoms, initial trigger event, results of the caloric testing, video head impulse test (vHIT) for all six semicircular canals and ocular and cervical vestibular evoked myogenic potentials (oVEMP and cVEMP). During the study period 147 consecutive patients with dizziness were examined and 28 (19%) were diagnosed with PPPD, 68% of them were women and the mean age was 59.5 ± 15 years. The median duration of symptoms was 23 months. The most common initial event was vestibular neuritis in 39.3% of patients, followed by benign paroxysmal positional vertigo in 10.7% of patients. Caloric testing was performed in 25 patients. It revealed six cases of unilateral canal paresis. vHIT was performed in 24 patients. There were 13 pathological responses with three cases of lateral canal dysfunction, two cases of posterior, one case of anterior and seven cases of multiple canals affection. VEMP was performed in 23 patients. There were five isolated oVEMP pathologies, one isolated cVEMP pathology and 11 findings of a combined oVEMP and cVEMP pathology. This study provides clinical and neurophysiological data on PPPD and indicates the utility of complete neurophysiological assessment of vestibular function in this group of patients. |
