The health advantages of high-intensity exercise are widely known but new research from McMaster University points to another major benefit: better memory. The findings could have implications for an aging population which is grappling with the growing problem of catastrophic diseases such as dementia and Alzheimer's.
In a Journal of the American Geriatrics Society study of community-dwelling individuals aged 70 to 90 years who were participating in the Jerusalem Longitudinal Study, leaving the house daily was linked with a lower risk of dying over an extended follow-up period, independent of social, functional, or medical factors.
Alzheimer's disease is caused by tangles in the brain made up of malfunctioning aggregated Tau proteins. Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published in Nature Communications and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.
A Japanese research group has revealed that elderly people with mild cognitive impairment (MCI) have a particularly weakened ability to memorize human faces in the short term when compared to healthy elderly people. MCI patients also had a different gaze behavior when trying to memorize a face. This research may lead to the early detection of dementia.
Understanding how brains actively erase memories may open new understanding of memory loss and aging, and open the possibility of new treatments for neurodegenerative disease.
In a new research article published in the Journal of the American Geriatrics Society, scientists were able to conclude that developing dementia or Alzheimer's disease (the most common form of dementia) did not appear to be linked to taking proton pump inhibitors (PPIs).
Nerve-stimulating procedures from ancient traditional acupuncture and the more modern electroacupuncture and neuromodulation relieves chronic pain, pelvic disorders and Parkinson's disease, and can be advantageous for treating inflammatory disorders like arthritis and deadly infections like sepsis.
A team of researchers from Sweden's Karolinska Institutet in Stockholm examined the factors that put older adults at higher risk for developing physical limitations as they age. Findings published in the Journal of the American Geriatrics Society suggest that reducing heart disease risk factors with appropriate treatments might help 'younger' older adults maintain their physical function.
Although most older Americans prefer to actively participate in making health care decisions, those with four or more chronic conditions are less likely to prefer active decision making. Researchers analyzed a random sample of 2,017 older adults who, with sample weights, represented approximately 33 million Medicare beneficiaries aged 65 and older.
Managing gout as a chronic, rather than an acute, condition could help prevent recurrences. A new study of more than 8,000 medical records found a positive association between starting treatment with allopurinol, a medication that helps prevent gout by lowering production of uric acid, and recurring doctor visits for the condition. Clinicians may therefore be more likely to offer allopurinol, or patients may be more likely to accept it, after multiple acute gout attacks.
