research
My research interest has been focused on the prevention strategies and psycho-social interventions for dementia. The prevention strategies under investigation include vitamin B, nutritional supplement, TaiChi and cognitive training. Since 2004, I have been director of the Jockey Club Centre for Positive, a service, training and research centre for people with dementia.
My other research focus is on osteoporosis and healthy ageing. I am the project leader in a large cohort study of 4,000 older men and women, which was started in 2001. The large data set has shown insights in the risk factors of osteoporosis, fractures, frailty, sarcopenia, functional decline, cognitive decline, atherosclerosis and mortality. As this study ran in parallel with two bigger cohort (MrOs) studies in the US and Sweden, there is much room for international comparisons and collaborative research. Further follow-up is on-going.
