Annotation	Using the 1993 Asset and Health Dynamics in the Oldest Old (sample size 7,443) and the 1998 Health and Retirement Survey (HRS, 7,624), this study used a version of the telephone Interview Screen to examine aggregate changes in non-institutionalised populations aged 70+ with severe cognitive impairment. The percentage of older Americans with severe cognitive impairment declined from 6.1% in 1993 to 3.6% in 1998. Improvements between those dates were not explained by shifts in demographic and socio-economic factors or by changes in the prevalence of stroke, vision, or hearing impairments. As a group, older people, especially those well into their 80s, appear to have better cognitive functioning now than in the early 1990s. (RH).
