Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change in Score on the Questionnaire for Impulsive Disorders in Parkinson's Disease | Baseline and 8 weeks | A newly developed and tested tool for measuring impulsivity in PD patients. |
| Primary | Change in Score on the Geriatric Depression Scale | Baseline and 8 weeks | This assessment detects depressive symptoms in subjects and is a commonly used neuropsychological scale. It is less influenced by motor / somatic symptoms compared to other depression scales. |
| Primary | Change in Score on the Barrat Impulsivity Scale | Baseline and 8 weeks | Scale is the most widely used self-report measure of impulsive personality traits. The BIS-11 is a 30-item self-report questionnaire that is scored to yield a total score, three second-order factors, and six first-order factors. |
| Primary | Change in Score on the Minnesota Impulsivity Disorders Interview | Baseline and 8 weeks | This is a clinician-administered screening instrument that had shown good reliability and validity in studies of adult and adolescent psychiatric patients. |
| Primary | Change in Score on the Iowa Gambling Task | Baseline and 8 weeks | a widely used, but complex, neuropsychological task of executive function in which mixed outcomes (gains and losses) are experienced together, to performance on a relatively simpler descriptive task, the Cups task, which isolates adaptive decision making for achieving gains and avoiding losses. It is very predictive of impulsive personality traits |
| Primary | Change in Score on the Montreal Cognitive Impairment Assessment | Baseline and 8 weeks | cognitive screening test designed to assist Health Professionals for detection of mild cognitive impairment, including Alzheimer's disease. |
| Secondary | Change in Score on the United Huntington's Disease Rating Scale - Motor section | Baseline and 8 weeks | A clinical examination of various cognitive, behavioral, and motor features commonly seen in patients with HD (Huntington Study Group, 1996). This is a standardized test used in most clinical studies of HD. |
