title: Depression and Parkinson's disease: a conceptual challenge.
abstract: OBJECTIVE
  To explore the relation between Parkinson's disease (PD) and depression from a conceptual point of view.
  
  
  METHODS
  Discussion of the relevant literature on the conceptual, phenomenological and therapeutical aspects of depression in Parkinson's disease.
  
  
  RESULTS
  Both semantic confusion and an erroneous belief in the mind-body distinction have contributed to some common misunderstandings of the nosology and etiology of depression in Parkinson's disease.
  
  
  CONCLUSIONS
  The consequences of a different, integrated, neuropsychiatric approach for both diagnosis and treatment are discussed.
