Depression is very common in PD and linked with a faster progression of physical symptoms, greater cognitive decline, and poorer quality of life. Non-pharmacological approaches, like cognitivebehavioral therapy (CBT), for the treatment of depression in Parkinson's disease (dPD) have received little experimental attention despite strong demonstrated efficacy in other geriatric and medical populations. Depressed PD patients often differ from the depressed non-PD elderly in that they present with increased rates of both executive dysfunction and co-morbid psychiatric diagnoses, may differ in their depressive symptom presentation, and typically have caregivers who are highly involved in their treatment. Therefore, it is not possible to conclude that empirically validated treatments in the depressed aged will generalize to those with Parkinson's disease. In order to be most effective for PD patients, CBT should be tailored to their unique needs. Additional controlled research is needed to further explore the efficacy of CBT for dPD.
