Examinations of a group of nondemented 85-year-olds show that the link between memory problems and dementia is not as clear in this age group. The 85-year-olds' ability to find words, to copy a geometric figure and to take quick decisions were some qualities that were evaluated in a psychiatric assessment. More than 300 individuals participated in the study, of which 17% had developed dementia three years later.
'We can't say that memory loss is the only meaningful sign of future dementia among 85-year-olds, since other symptoms, such as difficulties finding words or drawing a geometric figure, were needed for their risk of developing dementia to increase', says Sacuiu.
The H70 study
H70, short for Health 70, is a unique population study at the Sahlgrenska Academy. The study was started in 1971 with an assessment of 70-year-olds. The individuals were followed up regularly for 30 years. A new H70 study was started in the year 2000. Its participants will be followed up again during 2009 at age 79. The study includes data on over 2000 residents of Gothenburg, Sweden. The participants have been examined both physically and mentally, and have made it possible for several research teams to pinpoint various trends in physical and mental health in the ageing population.
