Education significantly improves mental functioning in seniors even four decades after finishing school, shows a new study published in the journal Demography by researchers at the International Institute for Applied Systems Analysis (IIASA) and the University of Linz.
European populations are growing older on average, a trend that could pose serious challenges to health care, budgets, and economic growth.
As a greater proportion of a country’s population grows into old age, average cognition levels and national productivity tend to decline, and the incidence of dementia increases.
“Finding ways to improve the cognition of seniors is of central importance to the economic well-being of aging countries,” says IIASA researcher Vegard Skirbekk, who worked on the study with researchers Nicole Schneeweis and Rudolf Winter Ebmer at Linz University
The study examined variation in years of schooling arising from compulsory educational reforms implemented in six European countries during the 1950s and 1960s, measuring mental functioning in seniors with various levels of schooling.
It shows that the burden of demographic change is likely to depend more on how healthy and mentally fit people are at different ages than on the exact age structure of people in a population. The study also shows that education tends to significantly boost brain function, and that this effect persists as a person ages.
The study shows that people who attended school for longer periods because of new regulations performed better in terms of cognitive functioning than those who did not. Using data from individuals aged around 60 from the Survey of Health, Aging and Retirement in Europe, the researchers found a positive impact of schooling on memory scores.
The fact that young people or their parents did not choose whether to go longer to school strongly suggests that schooling is the cause rather than personal characteristics that would affect this choice and could also explain the differences in cognitive function.
“Examining the variation in compulsory schooling was key.” It allowed us to find out that education was the cause of better cognitive function, and not a simple correlation,” says Winter-Ebmer.
Furthermore, the study finds evidence for a protective effect of schooling for the brain: more education slows cognitive decline. The researchers say that education can be an important measure for maintaining cognitive functioning and protecting against cognitive decline, thereby alleviating the challenges that population aging would otherwise present.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
