Abstract

The Older Australian Twins Study is a longitudinal, multi-centre study that investigates healthy brain ageing in older twins (65+ years). OATS commenced in New South Wales in January 2007, in Queensland in December 2007, and in Victoria in February 2008. Since the OATS study started we have followed our twin volunteers up every two years to check on their psychological and physical health. Participants undergo rigorous medical and cognitive function tests, with many participants’ also providing bloods samples and having a magnetic resonance imaging (MRI) scan of their brain. In 2015 we finished our 4-year follow ups. OATS assessed 623 participants at baseline, 450 at the 2-year follow up, and 389 completed their 4-year follow-up.
