Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this observational study, we will retrospectively analyze 38 PD patients who received bilateral STN DBS in the First Affiliated Hospital of Sun Yat-sen University during the year of 2008-2012. All patients will be evaluated by Unified Parkinson's Disease Rating Scale part III(UPDRSIII) before and after operation. Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment(MoCA) in the on medication condition pre-operation and on stimulation on medication condition post-operation. The follow-up time points are one week pre-operation and 6, 12, 24 months post-operation. Before operation, white matter hyperintensities（WMHs）in the cholinergic pathways will be determined on a 3.0 Tesla MRI, using the visual rating scale of Cholinergic Pathways Hyperintensities Scale (CHIPS). A correlation analysis will be conducted to investigate the relationship between CHIPS score and the change of cognitive status of PD patients after bilateral STN DBS retrospectively.
