Impact of anxiety, apathy and reduced functional autonomy on perceived quality of life in Parkinson's disease

The finding indicated that anxiety, apathy associated with impaired planning, attention and organization (i.e., executive apathy evaluated by the Dimensional Apathy Scale) and reduced functional autonomy contribute significantly to reduce the HRQoL in PD. Therefore, early identification and management of these neuropsychiatric symptoms should be relevant to preserve HRQoL in PD.
