Preventing Cognitive Decline in African Americans With Mild Cognitive Impairment
This trial is active, not recruiting.
|Condition||mild cognitive impairment (mci)|
|Treatments||behavioral activation (ba), supportive therapy (st)|
|Sponsor||Thomas Jefferson University|
|Collaborator||Dartmouth-Hitchcock Medical Center|
|Start date||September 2010|
|End date||December 2016|
|Trial size||200 participants|
|Trial identifier||NCT01299766, 1R01AG035025|
The goal of this study is to determine whether increasing participation in cognitive, physical, and/or social activities prevents cognitive decline in older African Americans (AAs) with Mild Cognitive Impairment (MCI). Patients with MCI are at increased risk for Alzheimer's Disease (AD); we propose that increasing participation in activities will prevent cognitive decline and may delay the onset of Alzheimer's Disease (AD). We will test this hypothesis by conducting a clinical trial in which older AAs with MCI (aged 65 years and older) will be randomized to Behavior Activation (BA) (a behavioral intervention that increases participation in daily activities) or Supportive Therapy (ST) (a person-centered psychotherapy that involves active listening and offering support focusing on participants' problems and concerns). We hypothesize that BA-treated subjects will have fewer declines in cognitive and functional abilities, fewer depressive and neuropsychiatric symptoms, and better quality of life than ST-treated subjects at 24 months.

|Description||The goal of this study is to determine whether increasing participation in activities prevents cognitive decline in older African Americans with Mild Cognitive Impairment (MCI). We will attempt to increase activities with Behavioral Activation (BA). BA is a manual-based, behavioral treatment to increase activities as a way to improve function and mood. As patients do more (through activation) and perceive the benefit (i.e., feel better), their activity levels increase. BA promotes activities that reflect an individual's preferences and goals by structuring, scheduling, and reinforcing daily activities. This increases participation in activities with strong personal value, such as social engagement or normative role function, which in turn enhances mood and motivation to remain active. The control treatment is Supportive Therapy, which is a non-directive, supportive therapy that is based on empathy, reflection, and support. This study is specifically targeting older African Americans (AAs). Most clinical trials for MCI have tested pharmacologic treatments and have enrolled mostly Whites; their results may not apply to AAs whose life experiences and medical and genetic characteristics may exert unique effects. Those with MCI are a high-risk population for whom interventions to prevent cognitive decline are particularly important. Because AAs comprise one of the largest minority groups in the U.S., suffer disparities in health outcomes, and are unlikely to seek pharmacologic treatments or participate in clinical drug trials, there is an urgent need to enroll older AAs in non-pharmacologic intervention studies of cognition. We will recruit 200 AA subjects aged 65 and older who have amnestic Mild Cognitive Impairment (MCI) - Multiple Domain subtype of MCI (aMCI-MD). One of the inclusion criteria is for participants to have a Knowledgeable Informant (KI) who is willing to participate in the study (with the subject's permission as documented in the informed consent form). A KI is defined as a family member or friend who is identified by the subject as someone who has regular and frequent contact with the subject (at least twice per week) in-person or by phone. The KI will be asked to provide information regarding the subject's functioning.|
