Abstract
The objective of this study was to examine the prevalence and consequences of coexisting vision and cognitive impairments in an Asian population. Data were collected from 4508 community-dwelling Singaporeans aged 60 years and older. Cognition was assessed by the Short Portable Mental Status Questionnaire whereas vision, disability, and self-rated health (SRH) were determined by self-report. Vision impairment was present in 902 (18.5%) participants and cognitive impairment in 835 (13.6%), with 232 (3.5%) participants experiencing both impairments. Persons with the comorbidity experienced higher odds of disability than persons with either single impairment. The association of vision impairment with SRH was stronger among women (odds ratio [OR] = 6.79, 95% confidence interval [CI] = 4.64-9.92) than among men (OR = 1.71, 95% CI = 1.21-2.41). Concurrent cognitive and vision impairment is prevalent in older Singaporeans and is associated with high rates of disability. Gender differences in vision-dependent roles may affect the patient-perceived impact of this comorbidity.

Professor of Medicine
My research relates to clinical practice improvement - from the development of clinical policies to their implementation in real world clinical settings. Most recently my major content focus has been cerebrovascular disease. Other major clinical areas in which I work include the range of disabling neurological conditions, cardiovascular disease, and cancer prevention. Notable features of my work are: (1) reliance on analytic strategies such as meta-analysis, simulation, decision analy

Heather Elizabeth Whitson

Professor of Medicine
Dr. Whitson's research is focused on improving care options and resilience for people with multiple chronic conditions.  In particular, she has interest and expertise related to the link between age-related changes in the eye and brain (e.g., How does late-life vision loss impact the aging brain or cognitive outcomes?  Is Alzheimer's disease associated with distinctive changes in the retina, and could such changes help diagnose Alzheimer's disease early in its course?).  Dr. Whits
