A strong association between gum inflammation and poorer cognitive performance in 70-year-olds has been found in a small study.

Following on from indications that gum disease might be a risk factor for dementia, analysis of data from 152 subjects in the Danish Glostrop Aging Study has revealed that periodontal inflammation at age 70 was strongly associated with lower cognitive scores (on the Digit Symbol Test).

  • A large study confirms that your cardiac health affects your brain, and provides evidence that the extent of this problem is greater than we think.

I have often spoken of the mantra: What’s good for your heart is good for your brain.

Two studies demonstrate why knowing whether you’ve told someone something is difficult for all of us, and that this is particularly so as you get older.

A number of studies have found that source memory (knowing where you heard/read/experienced something) is a particular problem for older adults. Destination memory (knowing who you’ve told) is an area that has been much less studied.

A large study of older African-Americans has found taking common medications with anticholinergic effects was correlated with an increased risk of developing mild cognitive impairment.

Anticholinergics are widely used for a variety of common medical conditions including insomnia, allergies, or incontinence, and many are sold over the counter.

A word experiment shows that unpleasant or traumatic events are likely to be inaccurately remembered, and this memory distortion increases with age. The findings have implications for eyewitness testimony.

Findings that children are less likely than adults to distort memories when negative emotions are evoked has significant implications for the criminal justice system.

Another study shows that older adults with low levels of vitamin D have higher levels of cognitive decline, particularly in executive function (but not attention).

Another study has come out showing that older adults with low levels of vitamin D are more likely to have cognitive problems. The six-year study followed 858 adults who were age 65 or older at the beginning of the study.

Older adults are more likely to forget that they've done something. A new study has found that doing something unusual (such as putting a hand on their head) at the same time helps seniors remember having done the task.

Previous research has shown that older adults are more likely to incorrectly repeat an action in situations where a

A new study finds a decision-making advantage to the increased difficulty older brains have in filtering out irrelevant information.

It’s now well established that older brains tend to find it harder to filter out irrelevant information. But now a new study suggests that that isn’t all bad.

More data from the National Survey of Midlife Development in the United States has revealed that cognitive abilities reflect to a greater extent how old you feel, not how old you actually are.

More data from the National Survey of Midlife Development in the United States has revealed that cognitive abilities reflect to a greater extent how old you feel, not how old you actually are. Of course that may be because cognitive ability contributes to a person’s wellness and energy.

A new study provides evidence that it's not age per se that affects the quality of decision-making, but individual differences in processing speed and memory.

A study involving 54 older adults (66-76) and 58 younger adults (18-35) challenges the idea that age itself causes people to become more risk-averse and to make poorer decisions.
