Age-related Cognitive Decline in Women May Start in Midlife
A new research suggests that age-related cognitive decline may start in women earlier than scientists previously believed. A team of researchers from the University of California, Los Angeles, wanted to examine the given evidence on cognitive decline in women.
For their study, the scientists collected data on the cognitive abilities of 2,709 healthy women from 42 to 52 years old. They analysed the results of 7,185 cognition tests with an average follow-up period of 6 years and 6 months. The study concluded that in general, during the 10-year period the women’s cognitive abilities deteriorated by an average 4.9%.
The authors of the study say: “This study provides good new evidence of cognitive aging in women in midlife, with significant longitudinal declines in both processing speed and verbal memory. Unlike previous longitudinal studies in midlife that were based on 3 or fewer cognition assessments, and could not adequately account for practice effects, we analyzed up to 6 annual or biennial assessments, allowing us to minimize the impact of practice effects and unmask declines.”
