Memory Problems More Common in Men?

07.09.2010
A new study shows that mild cognitive impairment (MCI) may affect more men than women. The research is published in the September 7, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Mild cognitive impairment is a condition in which people have problems with memory or thinking beyond that explained by the normal rate of aging. The study found that MCI was 1.5 times higher in men compared to women. MCI often leads to Alzheimer’s disease.

“This is the first study conducted among community-dwelling persons to find a higher prevalence of MCI in men,” said study author Ronald Petersen, MD, PhD, with the Mayo Clinic in Rochester, Minn. and a member of the American Academy of Neurology. “If these results are confirmed in other studies, it may suggest that factors related to gender play a role in the disease. For example, men may experience cognitive decline earlier in life but more gradually, whereas women may transition from normal memory directly to dementia at a later age but more quickly.”

For the study, 2,050 people between the ages of 70 to 89 in Olmstead County, Minn. were interviewed about their memory and their medical history and tested on their memory and thinking skills.

The study found that nearly 14 percent of participants had mild cognitive impairment, about 10 percent had dementia and 76 percent of those tested had normal memory and thinking skills. A total of 19 percent of men had mild cognitive impairment, compared to 14 percent of women.

“Our results, showing combined rates of MCI and dementia at 22 percent highlight the public health impact these conditions have and the importance of finding treatments for them,” said Petersen. People in the study who had a low level of education or were never married also had a higher rate of MCI.

The study was supported by the National Institute on Aging, as well as the Robert H. and Clarice Smith and Abigail Van Buren Alzheimer’s Disease Research Program of the Mayo Clinic.

The American Academy of Neurology, an association of more than 22,000 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 epilepsy, dystonia, migraine, Huntington’s disease, and dementia.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
