The Healthy Brain Project is an online research platform that aims to understand genetic and environmental factors that may increase risk for or protect against memory loss and the development of dementia in older age. Our research team is based at The Florey Institute of Neuroscience and Mental Health in Melbourne, Victoria, Australia. This research involves brief game-like tests, available on smartphones, to examine levels of cognitive function over time. This app may be used by individuals who are registered with the Healthy Brain Project.
