Deep Brain Stimulation in HUCH Region Between 2006 and 2014

Study Overview
=================
Brief Summary
-----------------
This study reviews the outcome of deep brain stimulation treated patients in Helsinki and Uusimaa University Hospital between 2006 and 2014. The aim of the study is to investigate the outcome and possible side effects of deep brain stimulation treatment.

Detailed Description
-----------------
Deep brain stimulation is a FDA approved method in treating patients with advanced Parkinson's disease when the best medical treatment is insufficient. In this study the aim is to investigate the outcome of deep brain stimulation treated patients in Helsinki and Uusimaa University hospital between 2006 and 2014. This study is a retrospective study based on existing patients' medical records and does not include an intervention in the treatment of an individual patient. Deep brain stimulation carries the risks of major surgery. A complication risk for a hemorrhage is 1-2 % and for an infection is 3-10%. The aim of this study is to evaluate the complications that have occurred and the possible benefit of deep brain stimulation in deep brain stimulation treated patients with advanced Parkinson's disease. The gathered data will be processed anonymously and an individual patient cannot be identified. The data will be processed with an appropriate statistical program (SPSS). No data will be given to external parties.
