In a change to previous research a new study carried out in Sweden points to a reduction in the risk of developing dementia.

Over 3,000 people (aged 75 and over) have been covered by the study since it commenced in 1987, and results so far show that the incidence of dementia has been stable and the longevity of people with the condition has increased over the period of the study.

Several reasons are given for this why this might be happening including earlier diagnosis and , medical interventions which delay the progression of the condition.
