To explore the possible subtypes and clinical characteristics of persistent postural-perceptual dizziness(PPPD). Methods: A total of 106 patients diagnosed with PPPD were selected from the Shanxi People’s Hospital between May 2023 and December 2023. General and clinical data of the patients were collected; upon admission, questionnaires including the Niigata PPPD Questionnaire(NPQ), Dizziness Handicap Inventory(DHI), Hospital Anxiety and Depression Scale(HADS), and State-Trait Anxiety Inventory(STAI) were administered. Factor analysis was conducted on the scale items, followed by cluster analysis based on the results of the factor analysis, with characteristic analysis performed for each patient group. Results: Factor analysis revealed three factors, named active motor factor(32.82% ), visual stimulation factor(14.80% ), and upright position factor(10.97% ). Cluster analysis identified three subtypes: visual stimulation-dominant subtype(n=25), posture control-dominant subtype(n=24), and active motor-dominant subtype(n=57). There were statistically significant differences in age, occupation, and family history of headaches among the three subtypes(P<0.05). The visual stimulation-dominant subtype patients had younger ages, with a notable family history of headache, and worked primarily as bank/supermarket clerks; the posture control-dominant subtype mainly consisted of civil servants, teachers; while the active motor-dominant subtype included predominantly workers, farmers. No statistically significant differences were found in other clinical data(P>0.05). Conclusion: The most common exacerbating factor for PPPD is active movement; it can be divided into three subtypes, each with significant characteristics in terms of age, occupation, and family history of headaches.
