CBT for Generalized Anxiety Disorder in Parkinson’s Disease: A Case Study

Abstract

ABSTRACT Objectives To examine the use of cognitive behavioral therapy (CBT) in a case of co-occurring generalized anxiety disorder (GAD) and Parkinson’s disease (PD). Methods This case study refers to a male aged 75 years with a diagnosis of Idiopathic Parkinson’s disease. It focuses on applying a CBT model to address the psychological difficulties with PD and GAD. Results This case study reveals key aspects in presentation, diagnosis, and psychological treatment between PD and GAD, and is one of few studies published in this area. Conclusions Symptoms of anxiety in an older adult with PD decreased during a course of CBT. The implications of the treatment outcome of this study and further considerations of treatment plans for comorbid PD and anxiety have been discussed. Clinical Implications Using CBT could positively impact non-motor symptoms of Parkinson’s, such as sleep difficulties and speech impediments. Using CBT for the catastrophic thinking and worry content in GAD seems to act as a complementary therapy for psychological/non-motor symptoms of PD.
