title: Treatment of Advanced Parkinson Disease and Related Disorders.
abstract: OBJECTIVE
  Parkinson disease often spans decades of a patient's lifetime. Over time, nonmotor symptoms predominate and may limit dopaminergic therapy. Neurologists continue to play a vital role in treatment. In addition to balancing neurobehavioral complications of Parkinson disease with motor benefit, addressing nonmotor symptoms common in the advanced stage may improve quality of life and reduce symptom burden. Symptoms such as dysphagia, constipation, urinary dysfunction, orthostatic hypotension, and pain respond to nonpharmacologic and pharmacologic therapies.
  
  
  RESULTS
  Evidence for treatment of many nonmotor symptoms is weak or lacking. The evidence for treatment of the atypical parkinsonian syndromes (progressive supranuclear palsy, multiple system atrophy, and corticobasal degeneration) in advanced stages is even more scant.
  
  
  CONCLUSIONS
  Engaging palliative care physicians in the joint care of patients can provide patients with access to expertise in end-of-life issues. Neurologic illnesses have specific hospice criteria to guide clinicians for referrals. Evidence supports that assisting patients with advance directives can result in improved satisfaction with care and improved quality of life in the last weeks of life. Neurologists can remain engaged in their patients' care throughout the course of illness.
