Use of the GDS-15 geriatric depression scale as a screening instrument for depressive symptomatology in patients with Parkinson's disease and their carers in the community

Abstract

This community-based study confirms the high level of depressive symptoms in PD suggested by hospital- and clinic-based studies. Depression in patients appears to be related to disease severity and cognitive impairment. An important determinant of carer distress and mood disorder, as reflected by the GDS score, appears to be the level of depression expressed by the patient being cared for. Despite high levels of depressive symptoms in both patients and carers, very few subjects were in receipt of antidepressant drug therapy.
