Conversations as a Means to Delay the Onset of Alzheimer's Disease
Conversational Engagement as a Means to Delay Alzheimer's Disease Onset

Past epidemiological studies have demonstrated that larger social networks, or more frequent social interactions, could have potential protective effects on the incidence of Alzheimer's Disease (AD). However, in those studies, indicators of social interactions were often broad, and included distinct elements that affected cognition and overall health. the investigators will examine whether conversation-based cognitive stimulations have positive effects on general, and domain-specific cognitive functions among the elderly. Face-to-face communication will be conducted through the use of personal computers, webcams, and user-friendly simple interactive Internet programs to allow participants to have social engagement while staying at their home and also for the cost effective execution of the study.

Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Prevention
Cognitive Impairment
  • Behavioral: Active social engagement group
    Engage in 30 minutes conversation daily using internet/webcam, 5 days per week for 6 weeks, tracking of daily conversational amount outside of the trial by using a digital recording device, lasting effects will be assessed at the 3rd and 6th month after completion of the intervention
  • Behavioral: Control group
    No active intervention, weekly phone calls by interviewer to complete health/social engagement monitoring survey, tracking of daily conversational amount by using a digital recording device
  • Placebo Comparator: Control group
    no daily conversational sessions with interviewers using webcam/internet. Weekly web-based heath form must be submitted using internet/PC. If not, subjects receive prompts from study personnel.
    Intervention: Behavioral: Control group
  • Active Comparator: Active soocial engagement group
