Cognitive‐behavioral therapy for depression in Parkinson's disease: A pilot study

Abstract

The present study was conducted to examine the feasibility and effect of an individual cognitive-behavioral treatment (CBT) for depression that was modified to meet the unique needs of the PD patient and incorporated a separate social support intervention for caregivers. Fifteen PD patients with Major Depressive Disorder participated in the study with a caregiver. Patients received 10-14 sessions of modified individual CBT. Caregivers attended 3-4 psychoeducational sessions, occurring separately from the patients treatment sessions, which focused on strategies for offering appropriate support, and ways to respond to the patients' negative thoughts in a targeted manner. Patients experienced a significant reduction in depressive symptoms and negative cognitions, and an increased perception of social support over the course of treatment. Gains were maintained at 1-month follow-up. In conclusion, individual CBT, when modified appropriately, may be a feasible and effective option for PD depression. Larger, randomized controlled trials are needed to further evaluate the efficacy of this intervention and to identify specific mechanisms of change.
