BACKGROUND : Parkinson’s disease (PD) is a common neurodegenerative disease, associated with severe impairment of quality of life.
Although the motor aspects of the illness are typically successfully treated with medications acting on the dopaminergic system, a
number of patients encounter progressive difficulties associated with their medical treatment.
RECOMMENDATIONS : Carefully selected patients will benefit from deep brain stimulation (DBS) treatment for their PD. Selection
requires dopamine challenge testing and neuropsychological testing for the presence of cognitive impairment. Careful follow-up and
programming of the DBS system are mandatory, and a major reason for DBS failure is inadequate programming and management of
CONCLUSION : DBS is a useful component of standard therapy for PD and may reduce symptoms, improve quality of life, promote patient
independence and reduce healthcare costs by reducing requirements for medicine.
