People in their seventies are less likely to develop dementia compared to someone of the same age decades ago, a study has found. Dementia is a general term for “loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life”, according to the Alzheimer’s Association.Researchers at the University of Queensland analysed data from more than 62,000 people over the age of 70 who were born from 1890 to 1948, with a view to determine whether there were generational differences in the prevalence of dementia.What did the study find?The analysis included data of 21,000 people from the US, 32,000 people from Europe and almost 9,000 people from England, with participants divided into eight birth cohorts and six age groups.Cohorts were grouped roughly into five blocks, with the earliest including people born between 1890-1913 and the most recent being 1944-1948.Dr Sabrina Lenzen from UQ’s
