“Our study suggests that rather than just paying attention to already known risk factors for dementia, such as diabetes or heart disease, keeping up with your general health may help reduce the risk for dementia,” said study author Kenneth Rockwood, MD, of Dalhousie University in Halifax, Nova Scotia, Canada.
The study included 7,239 people free of dementia ages 65 and older from the Canadian Study of Health and Aging. After five years and again after 10 years, they were evaluated for Alzheimer’s disease and all types of dementia. Participants were asked questions about 19 health problems not previously reported to predict dementia. Problems included arthritis, trouble hearing or seeing, denture fit, chest or skin problems, stomach or bladder troubles, sinus issues, broken bones and feet or ankle conditions, among others.
After 10 years, 2,915 of the participants had died, 883 were cognitively healthy, 416 had Alzheimer’s disease, 191 had other types of dementia, 677 had cognitive problems but no dementia, and the cognitive status of 1,023 people was not clear.
The study found that each health problem increased a person’s odds of developing dementia by 3.2 percent compared to people without such health problems. Older adults without health problems at baseline had an 18 percent chance to become demented in 10 years, while such risk increased to 30 percent and 40 percent in those who had 8 and 12 health problems, respectively.
“More research needs to be done to confirm that these non-traditional health problems may indeed be linked to an increased risk of dementia, but if confirmed, the consequences of these findings could be significant and could lead to the development of preventive or curative strategies for Alzheimer’s disease,” said Jean François Dartigues, MD, PhD, with the National Institute of Health and Medical Research (INSERM) in Paris, France, in an accompanying editorial.
The study was supported by the Canadian Institutes of Health Research, the Nova Scotia Health Research Foundation and the Alzheimer Society of Canada.
The American Academy of Neurology, an association of more than 24,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
