Официальное название

A Prospective Observational Study for the Predictors of Clinical Outcomes of Deep Brain Stimulation in Parkinson's Disease

Обзор

The goal of this observational study is to identify factors in blood that are associated with response to deep brain stimulation (DBS) surgery in patients with Parkinson's disease. The main questions it aims to answer are: 1. What factors in blood (proteins and RNA) are associated with good vs poor response to DBS? 2. Are these factors able to predict response to DBS? 3. How do these factors change before and after DBS? Blood and leftover brain tissue (which spontaneously adhere to the surgical instruments) will be taken and routine clinical data (including scores from routine assessments) will be collected from consenting participants who undergo DBS.

Подробное описание

This is a prospective observational study that investigates the clinical, proteomic, transcriptomic, and genomic profiles that are associated with DBS response with regards to motor symptoms, axial symptoms, non-motor symptoms, change in medications, activities of daily living (ADLs), and quality of life (QOL). The investigators will take blood samples from participants but will not take extra brain tissue; only leftover brain tissue (which is routinely discarded) that spontaneously adheres to surgical instruments will be collected. Study participation will not change the surgical procedure in any way. The investigators also aim to characterize the change in these multiomic profiles before versus after DBS treatment, to evaluate the ability of these multiomic profiles to predict and stratify response to DBS, and to identify modifiable factors to improve response to DBS. Additionally, the investigators will use these multiomic profiles, patient demographics, and clinical presentation to develop a DBS prediction model with advanced explainable AI (XAI) techniques.
