Their study is the first of its kind to look at the relationship between cynicism and dementia. Entitled: 'Late-life cynical distrust, risk of incident dementia, and mortality in a population-based cohort', it is published in the latest issue of the journal Neurology. Over a period of eight years, the researchers studied 1,499 people, who all had an average age of 71. The participants were given tests for dementia and a questionnaire to measure their level of cynicism, based on the Cook-Medley Scale."
