Older patients with persistent postural-perceptual dizziness exhibit fewer emotional disorders and lower vertigo scores

The clinical characteristics of persistent postural-perceptual dizziness (PPPD) vary according to patient age and inducing factors. We aimed to analyze the differences in the clinical characteristics of PPPD with different patient age groups and different etiologies. A total of 122 PPPD patients hospitalized in the vertigo ward of Nanjing Brain Hospital from December 2018 to July 2021 were enrolled. According to whether dizziness symptoms were secondary to organic diseases, PPPD patients were divided into the primary (p-) and secondary (s-) PPPD groups; subgroups were created according to age including youth group, middle-aged group, older adults group 1 and older adults 2. We collected detailed data from each patients, including scores on the Dizziness Handicap Inventory (DHI), mental state and other clinical data. The ratio of males to females was 1:2. The prevalence of emotional disorders in the middle-aged group was the highest (67.57%) and that in the older adults groups was lower (48.08% in older adults group 1 and 8.70% in older adults group 2, P = 0.000). The proportion of p-PPPD patients with emotional disorders was significantly higher than that of s-PPPD patients (53.48% vs. 30.56%, P = 0.028). The average total DHI score in the middle-aged group was significantly higher than that in older adults group 2 (52.86 vs. 35.04, P = 0.032), and the Beck anxiety score in the middle-aged group was higher than that in older adults group 2 (38.89 vs. 27.65, P = 0.000). The middle-aged group had the highest proportion of women, the highest proportion of patients with emotional disorders and the highest vertigo score. The proportion of patients with emotional disorders and the vertigo scores were lower in the older adults groups.
