Baby baby boomer are experiencing a astute drop in cognitive function as they age , relative to old genesis , according to a late work . The findings not only suggest that boomers will be more likely to develop precondition like dementedness than past cohort , but succeeding aging coevals may be at a similar heightened risk .
The subject field , publishedin The Journals of Gerontology : Series B deep last calendar month , looked at the cognitive test account of over 30,000 Americans over the eld of 50 who were enrolled in an existing , long - running research task by the University of Michigan , called the Health and Retirement Survey . As part of the task , Tennessean were expect interview questions meant to evaluate their cognitive function every two years . Questions admit counting rearwards from 100 in increments of 7 and having to recall the name of recent objects they were shown . All tell , the bailiwick analyzed nearly 20 days deserving of test score , collected from 1996 to 2014 .
Though people do generally lose a stone’s throw or two in their brain ability as part of the normal aging physical process , the bailiwick find there was an meliorate trend in cognitive occasion across generations born before and during World War II . The study had information for the abide by cohorts : Greatest Generation ( born 1890 - 1923 ) ; Early Children of Depression ( bear 1924 - 1930 ) ; Late small fry of Depression ( bear 1931 - 1941 ) ; War Babies ( born 1942 - 1947 ) ; early baby boomers ( born 1948–1953 ) ; and mid child boomers ( take over 1954–1959 ) .

While each generation before the baby boomer had ameliorate late - life noesis compared to the one before it , the baby boomer showed a decline equate to state of war babies , breaking the pattern of advance .
“ It is shocking to see this decline in cognitive operation among sister boomers after generations of increases in trial sexual conquest , ” cogitation generator Hui Zheng , prof of sociology at The Ohio State University , say in astatementreleased by the university . “ But what was most surprising to me is that this declension is witness in all groups : men and women , across all race and ethnicities and across all instruction , income and wealthiness levels . ”
Zheng also tried to calculate for long time - related decline in cognition by look only at the score of people in their former 50s . But again , other baby boomers in their 50 on average had lower test scores than did people from earlier generation in that same age group . That likely have in mind that whatever is causing this drop in cognition , the declination start becoming apparent by the sentence baby boomers were still halfway - aged .
This character of study ca n’t show what might be behind the drop in cognitive mapping . But Zheng did endeavor to report for possible factor that could have influenced these trends in his analytic thinking . Improvements in puerility nutrition and wellness throughout the 20th 100 in all probability help explain why pre - World War II generation pop to have safe cognition than the predate generation , at least in the data Zheng had available . But infant boomer had these advantages and more , since they also live overall gains in training and working conditions . At the same time , babe boomers in general were probably exposed to higher rates of other divisor tie in to decline cognitive mapping .
“ The fundamental causes include broken wealth , downhearted likelihood of being married , higher grade of solitariness and depression , and higher point of cardiovascular jeopardy divisor ( e.g. , obesity , physical inactiveness , hypertension , diabetes , solidus , heart disease ) , ” Zheng said in an email to Gizmodo . He also observe that the U.S. has its own supply roadblocks , such as the lack of universal , affordable health aid .
The determination may also explicate a seemingly contradictory blueprint other research had shown , Zheng aver . child boomer are already known toexperiencemore chronic wellness problems than earlier recent generations did at their age . But other studies havesuggestedthat the incidence rate of dementia and cognitive impairment among sure-enough Americans has been better over the decennary , relative to past generation . Zheng ’s research suggest that this trend wo n’t continue and that we simply have n’t turn over the pointedness in time where many boomers would become more stirred by conditions like Alzheimer ’s .
However , the old baby boomers are now in their 70s , while the untested are approaching their 60s . So if Zheng ’s findings do defend a real far-flung decline in knowledge across generation , then it ’s likely there will be a increase in the rates of Alzheimer ’s disease and other forms of dementedness , since early cognitive decline is a major risk element of later dementedness . And if whatever factors that are negatively affecting infant baby boomer are still around or get worse in the time to come , then Gen - Xers and millennials eventually could be facing the same or larger challenge .
Because there are now more older Americans than ever , public health expert predict there will be more cause of Alzheimer ’s in the near future tense . The Alzheimer ’s Association , for example , estimatesthat the number of Americans over eld 65 with Alzheimer ’s may grow to 13.8 million by 2050 , up from the 5.8 million believe to have the disease now . It ’s potential , according to Zheng , that the trouble could be even worse than we think . At the same time , Zheng does n’t mean that we ’re necessarily condemn .
“ Cognitive performance may persist in declining among baby boomers if no effective interventions and policy responses are in space , which may stimulate the prevalence of dementedness to substantially increase in the coming decades , ” he said . “ But this is not an irreversible drift . ” Zheng suggested that everyone can strive for more physical bodily function , a healthy dieting , and strong social bonds to lower their endangerment of cognitive decline later in life .
