title: [Dilemmas in the treatment of psychiatric symptoms in patients with Parkinson's disease].
abstract: BACKGROUND
  Psychiatric symptoms are common in Parkinson's disease (PD) and may complicate treatment.
  
  
  OBJECTIVE
  To review the prevalence and treatment options of psychiatric symptoms in PD patients and discuss the dilemmas that may arise.
  
  
  METHODS
  Literature review.
  
  
  RESULTS
  Psychiatric complaints, including depression, anxiety, apathy, impulse control disorders, hallucinations, delusions, sleep disturbances, and cognitive symptoms, frequently occur in PD patients. These symptoms have a great influence on the general functioning and quality of life of the patient. When treating these symptoms, adjusting neurological treatment and starting or adjusting psychotherapeutic or psychopharmacological treatment may be necessary. Even if individual symptoms can often be treated adequately, unwanted side effects in other symptom domains have to be taken into consideration.
  
  
  CONCLUSIONS
  Adequate treatment of neuropsychiatric symptoms in PD patients is complex, and requires close multidisciplinary collaboration, especially in more advanced disease stages.
