Clinical Response of Impulsivity After Brain Stimulation in Parkinson's Disease — CRIPS  

Parkinson Disease Clinical Trial

Official title: Multicentre Observational Study of Impulsive Behaviours Following Deep Brain Stimulation in Parkinson's Disease

Status Not yet recruiting

Clinical Trial Summary

The objective of this prospective observational cohort study is to answer the following clinically important questions: 1. In patients with a pre-operative history of ICBs, what is the likelihood of improvement or deterioration in ICBs post-operatively? 2. What is the risk of developing post-operative de novo ICBs after Subthalamic Nucleus DBS (STN DBS)? 3. Which factors are important in predicting changes in ICBs after STN DBS? 4. What is the impact of ICBs on carer's quality of life QoL and burden?

Clinical Trial Description

The study will record outcomes related to ICBs for PD patients who have already been selected for DBS therapy as a routine clinical treatment in participating in DBS operating centre It is routine practice to assess ICBs before DBS decisions are made, but the manner varies across DBS operating centres. The only additional factor to the routine DBS clinical pathway in this study is that the centres involved will perform assessments in a uniform manner to allow data to be combined. A unified set of clinical assessment scales for Impulsive Control Disorders ICDs and ICBs, as well as other relevant neuropsychiatric symptom assessment, will be added to routine pre- and post-operational clinical assessments for participants. The primary endpoint of the study is the change in severity of ICBs. If subjects score above 1 in any of given questions on QUIP-RS, or if subjects had disagreement with carers regarding scores, The Parkinson's Impulse-Control Scale, PICs will be triggered. PICs then will be administered by our trained research fellow (AA), over phone or in the clinic. Other scales to be administered are listed below: 1. Neuropsychiatric Inventory (NPI) 2. General anxiety disorder-7 (GAD-7) 3. Patient Health Questionnaire-9 (PHQ9) 4. Parkinson's disease questionnaire-39 (PDQ-39) 5. EuroQol 5 Dimension (EQ-5D) 6. Clinical Global Impression - Severity scale (CGI-S) at baseline and Clinician's Global Impression - Improvement scale (GGI-I) post-operatively. 7. Zarit Caregiver Burden Scale 8. Work and Social Adjustment Scale 9. UPPS-P Impulsive Behaviour Scale Assessments will be performed at baseline, 3, 6 and 12 months post-operatively. Results will be analysed to ascertain potential predictive measures for ICBS development/change. ;
