Abstract:
Depression and anxiety are some of the most common comorbidities arising in patients with Parkinson's disease. However, their timely recognition and diagnosis are often hindered by overlap with other somatic features and a low rate of self-report. There is a need for greater awareness and for better assessment and treatment options are highly required. Currently available scales can serve as tools to monitor change over time and the effect of interventional strategies. Development of new therapeutic strategies, including nonpharmacological approaches such as transcranial magnetic stimulation and deep brain stimulation, may provide alternatives to currently available treatment approaches. In this chapter we will give an overview of the most recent advances in the diagnosis and treatment of these important nonmotor symptoms.
