简要总结
Loss of cognitive abilities leading to Alzheimer's disease is progressive and destructive, leaving older adults disabled and unable to recall their past. The number of older adults with Alzheimer's disease is expected to triple by the year 2050, yet little research examines amyloid beta deposition, executive function, and progression of disability. This study will test the influence of a novel and promising non-pharmacological intervention, Strategy Training, on the progression of disability in a sample of 150 older adults with Mild Cognitive Impairment who have the option to complete a Positron Emission Tomography (PET) Imaging with Pittsburgh Compound B (PiB).
详细描述
This trial will test the effect of Strategy Training compared to Enhanced Usual Care on change in disability among older adults with Mild Cognitive Impairment (MCI) and assess the extent to which Central Nervous System amyloid-beta deposition and neurocognitive function modify the relationship between Strategy Training and Enhanced Usual Care on change in disability. Assessments will be obtained at Baseline, 8 week short assessment, 6 and 12 months post intervention. Interventions, such as Strategy Training, focused on slowing emergence of disability despite underlying pathology may keep older adults as engaged in meaningful daily activities for as long as possible. This project tests a novel and promising non-pharmacological intervention and will inform our understanding of important effect modifiers- amyloid beta deposition and executive function- on change in performance of cognitively challenging daily activities. Enhancing our understanding of amyloid beta deposition, executive function, disability, and a promising non-pharmacological intervention could support aging for millions of older adults who, in the near future, will experience disability related to MCI.

研究组 & 干预措施
Strategy Training
In addition to receiving everything in Enhanced Usual Care, participants will engage in 10 sessions over 5 weeks with a trained research interventionist. Participants will describe activities they do, no longer do, or have never done using the cards from the Activity Card Sort as a guide. The therapist will ask the participants to use this information to identify and prioritize activity-based goals to address in the remaining sessions. These sessions will take place in a location of the participant's choice and will last approximately 1 hour.
干预措施: Strategy Training (Behavioral)
Enhanced Usual Care
Enhanced usual care will allow older adults to interact with services and support. All mental health treatment (e.g., medications that you may be taking) and psychotherapy (e.g. counseling or social services) will be documented and monitored. Furthermore, all participants assigned to Enhanced Usual Care will receive the same assessments as other participants. The close monitoring will track potential changes in symptoms (e.g., depressive symptoms), and participants will be referred to services as appropriate.
干预措施: Enhanced Usual Care (Other)
结局指标
主要结局
Change in disability
时间窗: Baseline to Month 12
Disability will be measured with the Performance Assessment of Self-Care Skills (PASS) through standardized, criterion-referenced performance assessment of cognitively challenging daily activities (i.e., shopping, bill paying, checkbook balancing, bill mailing, telephone use, medication management, critical information retrieval, and small device repair). A trained and blinded assessor will provide instruction and then observe participants performing each task. If the participant demonstrates difficulty, the assessor provides cues to assist. Assessors will rate disability based on the number of cues needed by the participants to complete the tasks. A higher score indicates more cues provided to complete the tasks or disability. The number of cues required for each task will be combined for a total number of cues provided on all 8 tasks. The outcome will be reported with a mean number of cues provided (range 0-300).
