Psychiatry Study: Parkinson Disease

Parkinson's Disease Clinical Trial

Official title: Improvement of Social Adaptation After Pre-operative Cognitive Remediation in Parkinson's Patients Profiting From a Bilateral Subthalamic Stimulation

Status Completed

Clinical Trial Summary

Main objective:

To assess the impact of a structured program of preoperative cognitive remediation on postoperative social adaptation in patients suffering from Parkinson's disease profiting from bilateral subthalamic nucleus stimulation.

Secondary objectives:

To assess in the same patients the impact of structured program of preoperative cognitive remediation on quality of life, mood, anxiety, apathy and psychologic, social and professional functioning depending on psychiatric symptomatology after intervention.

Clinical Trial Description

Prospective, longitudinal, controlled, multicentric, randomised, open study.

Subjects: 3 groups of 40 patients (n=120): one group of patients profiting from a structured program of preoperative cognitive remediation (SICRPPD group: Specific Individual Cognitive Remediation Program in Parkinson's Disease), one group of patients profiting from a preoperative non structured accompaniment (ICM group: Intensive Care Management), one control group (CG group: Control Group).

Required sample size: The sample size of 40 patients/group will allow to demonstrate with a significance threshold of 5% and a power of 80% a difference of evolution of the global SAS SR score of 0.75 SD between 2 of the 3 groups. For an intended SD of 0.2 units, the threshold corresponds to a difference of 0.15 units, minimal significant change.

Intervention: The structured program of preoperative cognitive remediation is divided in 3 parts: one interview with the patient to do a building of the subjective theories (difficulties due to the disease, hope relative to the intervention), a study meeting of the cognitive remediation possibilities and a cognitive remediation meeting with the patient. The spouse will be included in the program.

Evaluation tools: Patients will be met before and after the intervention for clinical evaluations and scales making: For the psychiatric evaluation: Mini International Neuropsychiatric Inventory (M.I.N.I.), Starkstein Apathy Scale, Montgomery and Asberg depression scale (MADRS), global functioning evaluation scale (EGF) and Hamilton anxiety scale (HAMA)/ For the social adaptation evaluation: Social Adjustment scale Self Report (SAS SR)/ For quality of life evaluation: 39-item Parkinson's Disease Questionnaire (PDQ-39)/ For the daily life activities, 'motor' symptomatology and treatment complications evaluation: Unified Parkinson's Disease Rating Scale (UPDRS, parties II, III, et IV).

Main criteria: change in the global score of the SAS SR scale.

Secondary Criteria: change in scores of the PDQ-39 (quality of life), HAMA (anxiety), Starkstein (apathy), MADRS (mood), EGF (psychologic, social, professional functioning, and depending on the psychiatric symptomatology) questionnaires.

Statistics: parametric and non parametric tests will be done for p < 0.05. ;
