The impact of disease duration in persistent postural-perceptual dizziness (PPPD) on the quality of life, dizziness handicap and mental health.

Abstract

Background: Persistent Postural-Perceptual Dizziness (PPPD) is a chronic functional disorder which interferes with the way individuals experience their personal, social and work life.

Objective: To study the impact of disease duration in PPPD on the quality of life (QOL), dizziness handicap and mental health on the patients.

Methods: A prospective study comparing the EQ-5D for QOL, Dizziness Handicap Inventory (DHI) and DASS-21 between 27 patients with PPPD and 27 of those who have recovered from an acute vestibular event. Similar parameters between PPPD patients with symptoms less than one year and more than a year were compared.

Results: The PPPD patients were predominantly females and middle-aged with significantly higher DHI scores (mean 48.3 + 25.7, p = 0.00002), higher total mean scores in the DASS-21 (mean 21.6 + 13.7, p = 0.009) and poorer QOL with mean EQ-5D VAS of 67.9 + 17.3 (p < 0.00001). PPPD patients with symptoms for more than a year had significant increase in physical handicap (p = 0.041) as well as anxiety levels (p = 0.008).

Conclusions: PPPD is predominantly seen in females and middle-aged which significantly reduces the QOL, increases dizziness handicap and increases depression, anxiety and stress levels. The increase in duration of illness further increases the anxiety levels and physical handicap.
