Dr. Andrew Lim
Lim is a neurologist and scientist in the Hurvitz Brain Sciences Research Program at SRI. He studies the impact of sleep and circadian function on cognitive decline, dementia and other diseases. He recently led a study looking at the relationship between fragmented sleep and blood vessel health in the brain. The study is the first to examine in detail blood vessels from the autopsied brains of elderly patients who had undergone sleep monitoring before they died. Lim found that people who had poor sleep and awakened frequently were 27% more likely to have severe arteriosclerosis, in which artery walls thicken and harden. The results suggest sleep quality may be used to identify seniors at risk of stroke. Lim is also leading two sleep health and brain studies to examine the sleep patterns of thousands of Ontario residents. The aim is to determine whether poor sleep is related to the development of common disorders.
