In a nationwide study authored by OSU faculty researchers found that American baby boomers scored lower on a test for cognitive functioning than previous generations had.
Specifically, findings discovered that average cognition scores of adults at age 50 increased from one generation to the next. The data starting with the greatest generation (birth years 1890-1923) and peaking with war babies (1942-1947).
Cognitive scores declined starting with early boomers (1948-1953) and decreased even further with mid boomers (1954-1959).
Even though a prevalence of dementia has declined recently in the U.S. the new study results suggest this trend could reverse in the coming years.
Researchers pointed out that while this “sudden” reversal is shocking, the most shocking fact is that the data of decline holds true over many groups—in both men and women, across all races, across education levels and across income levels.
The data demonstrated that less wealth in addition to higher levels of loneliness, depression, inactivity and obesity along with less likelihood of being married all could play a role in this cognitive decline.
