Abstract
Persistent postural-perceptual dizziness (PPPD) is a chronic functional vestibular disorder that persists for more than three months and significantly impairs patients' mental health and quality of life (QoL). The onset and persistence of PPPD are believed to involve excessive attention to symptoms, requiring approaches from both physical and psychological perspectives. Morita therapy (MT) is a psychotherapy that aims to improve symptoms through defocusing attention from symptoms. This article reports a case in which five sessions of MT were conducted for a PPPD patient who had shown resistance to conventional treatments such as pharmacotherapy with selective serotonin reuptake inhibitors (SSRIs) and vestibular rehabilitation (VR). As a result of the intervention, the patient's excessive attention to dizziness symptoms decreased and participation in previously avoided activities was promoted, leading to marked improvements in dizziness symptoms, anxiety, depressive symptoms, and QoL. These effects were maintained at the three-month follow-up after treatment completion. This case suggests that MT could be a promising treatment option for PPPD patients who do not respond to existing treatments.
