First, a neurologist with expertise in movement disorders evaluates the patient. Patient selection is particularly important for successful subthalamic nucleus (STN) deep brain stimulation (DBS), because a number of factors determine positive surgical outcome. [97, 98] These can be summarized as follows:

  • A diagnosis of Parkinson disease

  • Positive response to levodopa

  • Absence of atypical parkinsonian features

  • Advanced disease, virtually unmanageable with dopaminergic medications

  • Relatively young age; however, advanced age (>75 years) is not an absolute contraindication to surgery (if a patient otherwise meets the selection criteria for a procedure and the quality of life is predicted to improve substantially, surgery should be offered)

  • No significant cognitive impairment

  • Absence of active psychiatric disease

  • Good social support and access to programming
