Pain Relievers Ibuprofen and Naproxen May Delay—Not Prevent—Alzheimer’s Disease

23.04.2009
A new study shows that nonsteroidal anti-inflammatory drugs (NSAIDs) such as the pain relievers ibuprofen and naproxen do not prevent Alzheimer’s disease, but they may instead delay its onset.

The study suggests a need for re-interpretation of earlier findings that suggested NSAIDs can prevent the disease. The research is published in the April 22, 2009, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Researchers identified 2,736 members of Group Health, an integrated healthcare delivery system, who did not have dementia when they enrolled in the study at an average age of 75. The investigators followed these people for 12 years to see if they developed Alzheimer’s or dementia. They checked Group Health pharmacy records for NSAID prescriptions and also asked participants about their use of NSAIDs.

Of the participants, 351 people had a history of heavy use of NSAIDs at the start of the study, and another 107 people became heavy NSAID users during the follow-up period. Heavy use was defined as having prescriptions for NSAIDs 68 percent of the time or more over a two-year period.

During the study, 476 people developed Alzheimer’s disease or dementia. The risk of developing dementia among heavy NSAID users was 66 percent higher than among people with little or no NSAID use.

“A key difference between this study and most of those done earlier is that our participants were older,” said study author John C. S. Breitner, MD, MPH, of the Department of Veterans Affairs and the University of Washington School of Medicine in Seattle. “It has been argued for some time that NSAID use delays the onset of Alzheimer’s disease. It would follow that studies looking at younger people who use NSAIDs would show fewer cases of Alzheimer’s, while in groups of older people there might be more cases, including those that would have occurred earlier if they had not been delayed.”

“This is one interpretation of the results, but other explanations are possible,” cautioned Breitner, who added, “We must not ignore the fundamental finding, which is an increase in the risk of dementia in the NSAID users. We need further research to understand that result more clearly.”

The study was supported by the U.S. Department of Veterans Affairs, the National Institutes of Health, and the Paul B. Beeson Career Development Awards in Aging Research Program.

The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as multiple sclerosis, restless legs syndrome, Alzheimer’s disease, narcolepsy, and stroke.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
