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: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
