New research from the University of East Anglia has found that cases of dementia in the over 65's has fallen by 1.8% in the last 20 years.
The study compared data from two decades ago to the present day and found there is now a smaller risk of anyone over 65 years of age developing dementia.
But because of a growing population of much older people, it doesn't mean the number of cases will fall. In fact, they will keep rising as the population does.
