91¶ÌÊÓƵapp and scientists working on The Disconnected Mind project at the University of Edinburgh's Centre for Cognitive Ageing and Cognitive Epidemiology (CCACE) have worked together to bring you these web pages. CCACE is a centre of excellence in research on how ageing affects thinking skills, and how mental ability in youth affects health and longevity. CCACE is funded by the Medical Research Council (MRC), the Biotechnology and Biological Sciences Research Council (BBSRC), and the University of Edinburgh.
