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.
Data was collected from all patients during standard clinical practice, and further to evaluate the characteristics of PPPD comparing with the control group.
A total of 43 patients diagnosed with PPPD were selected as the study group for analysis.
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.
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.
持续性姿势-知觉性头晕（PPPD）是慢性头晕的常见原因，但仅有少数研究报道过其临床特征，且国内尚无相关研究。因此，本研究旨在首次在中国分析PPPD的特征。
在标准临床实践中收集所有患者的数据，并进一步评估PPPD与对照组相比的特征。
共选取43例诊断为PPPD的患者作为研究组进行分析。
研究组中女性占比显著高于男性，大多数病例的发病年龄在中年，与对照组相比睡眠质量明显下降，焦虑水平在统计学上显著更高。人格分析表明，神经质显著高于对照组。
在本样本中，我们发现PPPD在女性患者中更为常见，发病年龄为40 - 60岁，大多数患者有睡眠障碍，焦虑是主要的情绪障碍，人格分析发现神经质人格可能是发生PPPD的危险因素。建议在中国开展进一步的大规模研究。
