Persistent Postural Perceptual Dizziness (PPPD) is a frequently encountered cause of chronic dizziness, significantly impacting daily life. Despite its prevalence, PPPD remains underdiagnosed, particularly in South India, where clinical data are limited. This study aims to assess the prevalence of PPPD and its clinical characteristics in this region. A cross-sectional study was conducted among 237 individuals aged 18 to 60 years using online surveys and in-person interviews with clinical evaluation. Diagnostic tools included the Niigata Persistent Postural-Perceptual Dizziness Questionnaire (NPQ), Dizziness Handicap Inventory (DHI), and Patient Health Questionnaire for Somatic Symptoms (PHQ-SADS) and GANS-SOP (Gans Sensory Organisation Performance) Test. Among the participants, 46 (22 females, 24 males) were diagnosed with PPPD, with a mean age of 37.80 ± 12.84 years. Visual dominance was a primary exacerbating factor in 18 individuals, while others were affected by upright posture and movement. DHI scores indicated significant emotional and functional impairment, with 22 reporting mild disability, 14 moderate, and 2 severe. PHQ-SADS revealed associations between PPPD and anxiety and depression symptoms. Findings on the GANS- SOP revealed the presence of a multifactorial pattern indicative of the deficits across vestibular, visual and proprioceptive systems. In conclusion, PPPD presents a considerable burden, affecting individuals across different age groups and genders. Improved awareness and diagnostic strategies are needed to address the challenges of diagnosing and managing PPPD effectively. Further research is warranted to refine diagnostic approaches and develop targeted interventions for this complex disorder.
持续性姿势性感知性头晕（PPPD）是慢性头晕的常见原因，对日常生活有重大影响。尽管其患病率较高，但PPPD仍未得到充分诊断，尤其是在印度南部，那里的临床数据有限。本研究旨在评估该地区PPPD的患病率及其临床特征。采用在线调查和面对面访谈结合临床评估的方式，对237名年龄在18至60岁之间的个体进行了横断面研究。诊断工具包括新潟持续性姿势性感知性头晕问卷（NPQ）、头晕残障量表（DHI）、躯体症状患者健康问卷（PHQ-SADS）和GANS-SOP（甘斯感觉组织性能）测试。在参与者中，46人（22名女性，24名男性）被诊断为PPPD，平均年龄为37.80±12.84岁。视觉优势是18名个体的主要加重因素，而其他个体则受直立姿势和运动影响。DHI评分表明存在明显的情绪和功能障碍，22人报告有轻度残疾，14人中度残疾，2人重度残疾。PHQ-SADS显示PPPD与焦虑和抑郁症状之间存在关联。GANS-SOP测试结果显示存在多因素模式，表明前庭、视觉和本体感觉系统存在缺陷。总之，PPPD带来了相当大的负担，影响着不同年龄组和性别的个体。需要提高认识和改进诊断策略，以有效应对PPPD诊断和管理方面的挑战。有必要进一步研究以完善诊断方法，并为这种复杂疾病制定有针对性的干预措施。
