Do you know what extension he's on? http://chemrok.com/ioe4healthcom-a4c7.pdf ioe4health.com  The research, published today in The Lancet, is part of the landmark Cognitive Function and Ageing Studies (CFAS), funded by the Medical Research Council. It shows that dementia rates have fallen in the past two decades, since the first such survey, CFAS 1, was carried out between 1989 and 1994. In the earlier study, just over eight in every 100 members of the over 65 population were estimated to have dementia, but in the new study, CFAS2, that rate has dropped to less than seven in every 100. Both studies looked at sample groups of more than 7,000 people, from all over the UK.
