Living with a partner reduces risk of Alzheimer’s

31.07.2008
Living with a spouse or a partner decreases the risk of developing Alzheimer’s and other dementia diseases.

This according to a study by Krister Håkansson, researcher in psychology at Växjö University and Karolinska Institutet, Sweden. The results were presented for the first time yesterday at the world’s largest dementia conference.

“This is, for me, an overwhelming start,” says Mr Håkansson. “It’s the first study I’ve done in this field, and the results are astounding. They indicate a very strong correlation between this type of social factor and the risk of developing dementia.”

The new findings are based on data from a Finnish study, which was unique in that 2,000 people were examined at the age of around 50 and again twenty-one years later. Normally, dementia researchers only study late-life individuals. Previous research has shown that an active lifestyle, both intellectually and socially, can decrease the risk of developing dementia; since a shared life often entails considerable social and intellectual stimulation, the point of inquiry of this present study was whether living with a spouse or a partner can help to ward off dementia.

The results show that people living with a spouse or a partner in midlife ran a 50 per cent lower risk of developing dementia than people living alone, even when controlled for other risk factors, such as age.

How long a person had been single and for what reasons also affected the chances of developing dementia. Those who had lived alone their entire adult life ran twice the risk, while those who were divorced in midlife and remained subsequently single ran three times the risk.

Widows and widowers ran the greatest risk
Those at greatest risk of developing dementia diseases were people who had lost their partner before middle age and then continued to live as a widow or widower. The study showed that the chances of developing Alzheimer’s for these individuals were six times greater than for married couples.

“This suggests two influencing factors – social and intellectual stimulation and trauma,” says Mr Håkansson. “In practice, it shows how important it is to put resources into helping people who have undergone a crisis. If our interpretation will hold, such an intervention strategy could also be profitable for society considering the costs for dementia care."

The new results were presented at the 2008 Alzheimer’s Association International Conference on Alzheimer’s Disease (ICAD 2008), the world’s largest in the field, which is currently being help in Chicago. For more news, visit the conference press room at http://www.alz.org/icad/press_room.asp

Krister Håkansson can already see several interesting lines of inquiry leading from this study. “Does it matter, for instance, if the relationship is a happy one or not? And does it matter if someone has always intended to live a single life or not?”

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
