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: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
