Games, puzzles can slow cognitive decline, MCI
Older people with mild cognitive impairment (MCI) who engage in high levels of activities such as word games and hobbies have better memory, working memory, attention and processing speed than those who do not, a recent study suggests. Although the study is observational and cannot prove cause and effect, active-aging organizations might consider adding these activities to regular programming and/or encouraging them among residents and members.

Alzheimer's diagnosis may depend on where you live
With new medications on the market or in the works for Alzheimer's disease and other types of dementia, a study suggests that getting the diagnosis needed to access these new treatments may depend on where you live. It's something active-aging organizations should be aware of, and perhaps provide support in areas where access to a diagnosis is low.

Overcoming hurdles to dementia diagnoses
A new white paper from healthcare data and consulting agency ECRI identifies challenges related to dementia diagnosis, with a focus on the roles of clinicians, patients, and caregivers. Importantly, it also offers actionable recommendations to address these challenges. It's a must-read for assisted living and dementia care staff and others who regularly engage with adults with cognitive impairment.

Stats: Unprocessed food consumption curbs MCI risk by 12%
People who consumer more ultra-processed foods like soft drinks, chips and cookies may have a higher risk of having memory and thinking problems and having a stroke than those who eat fewer processed foods, according to a recent study. The study does not prove that eating ultra-processed foods causes memory and thinking problems and stroke -- it shows an association. However, it offers one more reason to ensure that such foods are not included on the menu or continuously available as snacks in active-aging communities.

Light therapy may improve Alzheimer's symptoms
Light therapy leads to significant improvements in sleep and psychobehavioral symptoms for individuals with Alzheimer's disease (AD), a recent study from China suggests. The cognitive decline associated with AD is often accompanied by sleep disturbances and symptoms such as apathetic and depressive behavior, agitation and aggression.

Tech Talk: Internet usage could halve dementia risk
Researchers recently found a link between regular internet use and a lower risk of dementia, though there was a suggestion that excessive internet use could have the opposite effect. "Online engagement may help to develop and maintain cognitive reserve, which can in turn compensate for brain aging and reduce the risk of dementia," said co-author Virginia W. Chang, MD, PhD, of New York University.
