Psychotherapy for the Treatment of Anxiety and Depression in Patients with Parkinson Disease: A Meta-Analysis of Randomized Controlled Trials

May 3, 2021

Anxiety and depression are major psychiatric nonmotor symptoms (NMSs) of Parkinson disease (PD). Although several studies have investigated the effects of psychotherapeutic interventions, particularly cognitive-behavioral therapy (CBT), for alleviating anxiety and depression in patients with PD, the findings have been inconclusive because of the small sample size and the lack of a unified protocol for such treatments. Thus, the present meta-analysis of randomized controlled trials (RCTs) was conducted to assess the effect of psychotherapy on PD-related anxiety and depression.
