Abstract. Evidence is reviewed demonstrating that cognitive behavior therapy (CBT) is effective in the treatment of depression
and anxiety in Parkinson’s disease. The aims were to review the extant literature, specify a model of cognitive and behavioral
maintenance factors in depression and anxiety in Parkinson’s disease and provide a guide to treatment. It is argued that treatment
should take into account specific cognitive and behavioral maintaining factors. Symptoms of depression and anxiety are highly
prevalent in Parkinson’s disease and therapists should consider how to augment the efficacy of CBT for patients with Parkinson’s
disease. Cognitive and behavioral interventions can help people overcome some of the challenges in living withPDby maximizing
wellbeing and overall quality of life.
