OBJECTIVE

Persistent postural-perceptual dizziness (PPPD) is a common cause of chronic dizziness, but only a few studies have reported its clinical characteristics, and no related research has been performed in China. Therefore, the purpose of this study was to analyze the characteristics of PPPD for the first time in China.

DESIGN

Data was collected from all patients during standard clinical practice, and further to evaluate the characteristics of PPPD comparing with the control group.

STUDY SAMPLE

A total of 43 patients diagnosed with PPPD were selected as the study group for analysis.

RESULTS

Women were significantly more represented in the study group than men, and in the majority of cases the age of onset was in middle-age, and sleep quality was clearly decreased compared with controls, with more statistically significantly higher levels of anxiety. Personality analysis identified that neuroticism was significantly higher than in controls.

CONCLUSIONS

In this sample we showed that PPPD was more represented in female patients, the age of onset was 40-60 years old, the majority of patients had sleep disorders, anxiety was the main mood disorder to be identified, and personality analysis found that neurotic personality may be the risk factor for developing PPPD. Further large scale studies are suggested in China.
