We have investigated functional connectivity of the default mode network (DMN) in normal aging and Alzheimer's disease (AD) using resting state fMRI at 3T. Images from young and elderly controls, and patients with AD were processed using spatial independent component analysis to identify the DMN. Functional connectivity was quantified using integration and indices derived from graph theory. Four DMN...
In this study, we explore whether there is correlation between the personal network and its impact on physical, mental and psychological health of aging population. Previous research on aging and health suggest the importance of individual family network and social network on different aspects of health assessments and outcomes. We examine the impact of family network and social network on physical,...
The purpose of this study was to evaluate the effects of computer pointing devices on computer using of aging people in Chinese mainland. A total of 16 elder users whose average age was 65 without any computer experience before were selected as subjects in a tracking task. Three pointing devices including traditional mouse, touch pad and track point in notebook were evaluated. The operation performance...
Detrended Fluctuation Analysis (DFA) aims to quantify the fractal correlation properties in nonstationary time series, and it has successfully been applied in the assessment of the Heart Rate Variability (HRV) for cardiac risk stratification purposes. However the physiological meaning of DFA indices and its relation with aging have not yet been completely established. Given that a loss of complexity...
