Well-functioning lungs reduce risk of dementia

16.05.2006


A middle-aged woman with well-functioning lungs runs less risk of developing Alzheimer’s disease. A new study carried out at the Sahlgrenska Academy in Göteborg, Sweden, shows a strong statistical correlation between lung capacity and dementia.



The findings are presented in the coming issue of the prestigious American journal Neurobiology of Aging.The study is based on the so-called Survey of Women in Göteborg, a population study that has been under way since 1968.

The study covers a total of 1,291 women. These women’s lung capacity was first monitored in 1974 and then in 1980 when the women were in middle age. The monitoring was the repeated several times up to 2000. Of these women, 147 had developed dementia, 96 of them in the form of Alzheimer’s disease.


The study shows that there is a clear statistical correlation between the functioning of their lungs and their risk of developing Alzheimer’s disease.

“Our theory is that poor lung function leads to the brain receiving less oxygen, and this in turn increases the risk of dementia,” says Xinxin Guo, a post-doctoral fellow at the Sahlgrenska Academy.

The better the lung function the women in the study had in middle age, the lower their risk of later developing Alzheimer’s disease. For each 20% of better lung capacity, the risk of acquiring Alzheimer’s declined by one quarter.

Dementia brings great suffering to its victims and their friends and relatives, and this health problem represents a huge cost to society. Some 200,000 Swedes have some form of dementia.

“This study underscores the importance of maintaining well-functioning lungs. If you exercise regularly and refrain from smoking, you can influence the risk of your contracting Alzheimer’s,” says Professor Ingmar Skoog.

Age and genetic heredity are the most important factors in the risk of developing dementia. Previous research has indicated that vascular disease and obesity increase the risk of dementia disorders, but this is the first report about a tie to the functioning of the lungs.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

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:...

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...
