| Popis: | Background Persistent postural-perceptual dizziness (PPPD) is a relatively new syndrome with diagnostic criteria being published in 2017. Aim of this study was to evaluate the clinical and neurophysiological characteristics of PPPD. Materials and methods This was a retrospective performed 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, ocular and cervical vestibular evoked myogenic potentials. Results 147 consecutive patients with dizziness were examined and 28 (19%) were diagnosed with PPPD. Most common initial event was vestibular neuritis in 39.3% of patients, followed by benign paroxysmal positional vertigo in 10.7% of patients. One patient had normal findings, one patient had signs of vestibular dysfunction on all of the tests, one had pathology demonstrated by vHIT only, seven patients had pathological VEMP, while five patients had vestibular dysfunction on both VEMP and vHIT. Neurophysiological evaluation results are presented in Table. All patients with unknown pathology who performed neurophysiological tests had normal calorics, while 3 out of 4 had vHIT abnormalities. Conclusion This study provides clinical and neurophysiological data on PPPD. |
