Depression is one of most common non-motor symptoms in Parkinson’s disease（PD）. Due to the overlap of somatic symptoms and other neuropsychiatric manifestations

assessing the depression of PD is still a challenge in clinical practice. It is of great importance to choose a valid and appropriate depression scale to detect it. Hamilton depression scale

Beck depression inventory

Montgomery-Asberg depression rating scale

geriatric depression scale

Cornell scale for depression in dementia can effectively evaluate different clinical types of depression in PD. Moreover

different clinical types of depression may need to choose different treatments. Among them

the cognitive behavioral therapy is effective

but easy to be ignored by the neurologist. With fewer side effects

oral antidepressant drugs are still the most commonly used

and depression in the "off"period can be improved by adjusting the dopaminergic drugs.The efficacy of repetitive transcranial magnetic stimulation and deep brain stimulation method still needs more controlled clinical study to be verified. Further improving the recognition to the depression of PD and developing more effective treatments

is crucial to help improve the patient’s quality of life.
