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.

Primary Outcome Measures:
  • Cognitive functions measured by neuropsychological tests [ Time Frame: up to 12 months ]
    Pre-post trial changes in neuropsychological test results among the experimental group will be compared with pre-post changes among the control group

Secondary Outcome Measures:
  • Psychological well-being [ Time Frame: up to 12 months ]
    Pre-post changes in psychological measures (loneliness scale, isolation score, self-rated health), self-rated cognitive functions at post trial assessment.

  • Levels of social engagement [ Time Frame: up to 12 months ]
    Pre-post changes in levels of social engagement

Enrollment: 96
Study Start Date: February 2012
Study Completion Date: September 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
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
Active Comparator: Active soocial engagement group
Active Social Engagement: Engage in 30 minutes conversation daily with interviewers using internet/webcam for 6 weeks
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
