Question: How effective is low intensity* individual cognitive behavioural therapy (CBT) in treating anxiety and/or depression in patients with Parkinson's disease?

Answer:

No definite clinical implications may be made based on the current evidence. There are a number of methodologically weak studies included in a systematic review that show that brief psychotherapy treatment (cognitive behaviour therapy or psychodynamic therapy) decreases depression in people with Parkinson's Disease, in comparison to controls. The authors of the systematic review suggested, however, that more high quality studies with long term follow-up are needed in this field of research. They also suggested that study authors consider using additional assessment tools for depression.

*For the purpose of this question, 'low intensity' refers to CBT-based interventions providing guided self-help, including bibliotherapy and brief individual therapy administered either in person or remotely (e.g. by telephone).
