Swedish Study Suggests the Prevalence of Dementia May Be Decreasing (Neurology)

Summary

A study – based on two cross-sectional surveys of people aged 75 years or over in Stockholm – explored whether the prevalence, survival, and incidence of dementia changed from 1987-1994 to 2001-2008 (in Stockholm, Sweden). The age- and sex-standardized prevalence of dementia was 17.5% (12.8% in men; 19.2% in women) in the 1987-1994 survey; and 17.9% (10.8% in men; 20.5% in women) in the 2001-2008 survey. It was found that the prevalence of dementia was stable from the late 1980s to the early 2000s in central Stockholm, Sweden, but the survival of patients with dementia had increased (probably due to improvements in health care); which implies that incidence of dementia may have decreased during the same period. This research is contrary to the widespread presumptions concerning an increasing incidence of dementia.
