Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
Apathy is one of the most common behavioral symptoms of Parkinson's disease. Patients with apathy show diminution in motivation and goal-directed behaviors, which is a fundamental aspect of human functioning, affecting dependency and quality of life. Although apathy is thought to be potentially treatable currently there are no effective treatments for apathy. Given the higher incidence of medical and psychiatric comorbidities, the Veterans Affairs health system represents a unique population for which medication response may be different from the general population. This study aims to evaluate if a medication that has already been proven to be useful in Alzheimer's disease patients with apathy, could be helpful in Parkinson's disease as well as decreasing its debilitating consequences and reducing patients' dependency on caregivers, providing well-deserved relief to patients and their loved ones.
Inclusion
- Clinically established or probable Parkinson disease according to the Movement Disorders Society Clinical Diagnostic Criteria for Parkinson's Disease
- Age 40 or older at the time of screening
- Montreal Cognitive Assessment (MoCA) score between 17-30.
- Clinical Dementia Rating scale (CDR) lower than 1 and CDR sum of boxes lower than 4.5. The CDR is a numeric scale used to quantify the severity of symptoms of dementia. Using a structured interview protocol, qualified raters assess the subject's cognitive and functional performance in six areas: memory, orientation, judgement, and problem solving, community affairs, home and hobbies, and personal care. Scores are combined to obtain a composite score ranging from 0 through 3. A score between 0 and 1 indicates none or mild symptoms. The individual scores can also be added up, which gives the sum of boxes score.
- Clinically significant apathy for at least four weeks for which either the frequency of apathy as assessed by the Neuropsychiatric Inventory (NPI) is 'Very frequently', or the frequency of apathy as assessed by the NPI is 'Frequently' or 'Often' AND the severity of apathy as assessed by the NPI is 'Moderate' or 'Marked'
- Provision of informed consent for participation in the study by the patient. The ability to provide consent will be determined by the Assessment of Capacity for Everyday Decision-Making (ACED). The total score must be 9 (out of 10) or higher to meet the criteria for the study.
Exclusion
- Meets criteria Major Depressive Episode according to the Diagnostic Statistical Manual of Mental Disorder 5
- History of psychotic symptoms due to another illness (i.e., schizophrenia, psychosis in mood disorders, etc.) in the past 2 years
- Clinically significant agitation/aggression for which either the frequency of agitation/aggression as assessed by the NPI is 'Very frequently', or the frequency of agitation/aggression as assessed by the NPI is 'Frequently' AND the severity of the agitation as assessed by the NPI is 'Moderate', or 'Marked'
- Clinically significant delusions for which either the frequency of delusions as assessed by the NPI is 'Very frequently', or the frequency of delusions as assessed by the NPI is 'Frequently' AND the severity of the delusions as assessed by the NPI is 'Moderate', or 'Marked'
- Clinically significant hallucinations for which either the frequency of hallucinations as assessed by the NPI is 'Very frequently', or the frequency of hallucinations as assessed by the NPI is 'Frequently' AND the severity of the hallucinations as assessed by the NPI is 'Moderate', or 'Marked'
- Clinically significant impulse control disorders as assessed by the QUIP
