70-year-olds smarter than before

Today's 70-year-olds do far better in intelligence tests than their predecessors.

Today's 70-year-olds do far better in intelligence tests than their predecessors. It has also become more difficult to detect dementia in its early stages, though forgetfulness is still an early symptom, reveals new research from the University of Gothenburg, Sweden, based on the H70 study.

"Using the test results, we've tried to identify people who are at risk of developing dementia," says Simona Sacuiu, resident in psychiatry at Sahlgrenska University Hospital and medical researcher at the Sahlgrenska Academy's Unit of Neuropsychiatric Epidemiology. "While this worked well for the group of 70-year-olds born in 1901-02, the same tests didn't offer any clues about who will develop dementia in the later generation of 70-year-olds born in 1930."
