Previous research has shown that older adults are more likely to incorrectly repeat an action in situations where a prospective memory task has become habitual — for example, taking more medication because they’ve forgotten they’ve already taken it. A new study has found that doing something unusual at the same time helps seniors remember having done the task. In the study, older adults told to put a hand on their heads whenever they made a particular response, reduced the level of repetition errors to that of younger adults. It’s suggested that doing something unusual, like knocking on wood or patting yourself on the head, while taking a daily dose of medicine may be an effective strategy to help seniors remember whether they've already taken their daily medications.

Common drugs that can cause memory problems in older adults
Submitted by Fiona McPherson

A large study, involving 3,690 older adults, has found that drugs with strong anticholinergic effects cause memory and cognitive impairment when taken continuously for a mere two months. Moreover, taking multiple drugs with weaker anticholinergic effects, such as many common over-the-counter digestive aids, affected cognition after 90 days’ continuous use. In both these cases, the risk of cognitive impairment doubled (approximately).
It’s not the noise in the brain; it’s the noise in the input
Submitted by Fiona McPherson

A new study has found that errors in perceptual decisions occurred only when there was confused sensory input, not because of any ‘noise’ or randomness in the cognitive processing. The finding, if replicated across broader contexts, will change some of our fundamental assumptions about how the brain works.
Genetic test shows risk of cognitive impairment rather than Alzheimer’s
Submitted by Fiona McPherson

Analysis of data from 418 older adults (70+) has found that carriers of the ‘Alzheimer’s gene’, APOEe4, were 58% more likely to develop mild cognitive impairment compared to non-carriers. However, ε4 carriers with MCI developed Alzheimer’s at the same rate as non-carriers. The finding turns prevailing thinking on its head: rather than the gene increasing the risk of developing Alzheimer’s, it appears that it increases the risk of MCI — and people with MCI are the main source of new Alzheimer’s diagnoses.
Forgetfulness in old age may be related to changes in retrieval strategy
Evidence is accumulating that age-related cognitive decline is rooted in three related factors: processing speed slows down (because of myelin degradation); the ability to inhibit distractions becomes impaired; working memory capacity is reduced.
A new study adds to this evidence by looking at one particular aspect of age-related cognitive decline: memory search.
Key attention region may underlie ‘super agers’ cognitive powers

A small study of “Super Agers” has found a key difference between them and typical older adults: an unusually large anterior cingulate (involved in attention), with four times as many von Economo neurons.
Regular exercise throughout life helps keep aging mind sharp

Data from the very large, long-running UK National Child Development Study has revealed that those who exercised at least four times weekly as both a child and an adult performed better on cognitive tests at age 50 than those who exercised two to three times per month or less, and the latter in turn performed better than those who hadn’t regularly exercised at all.
Learning Facebook may keep seniors sharp
Submitted by Fiona McPherson
on
Preliminary findings from a small study show that older adults (68-91), after learning to use Facebook, performed about 25% better on tasks designed to measure their ability to continuously monitor and to quickly add or delete the contents of their working memory (updating), compared to their baseline performance. Two other groups of 14 showed no change. The second group of 14 were taught to use a private online diary site (Penzu.com), while the third control group were told they were on a wait-list for Facebook training.
Hearing loss accelerates cognitive decline in older adults
I’ve written before about the gathering evidence that sensory impairment, visual impairment and hearing loss in particular, is a risk factor for age-related cognitive decline and dementia. Now a large long-running study provides more support for the association between hearing loss and age-related cognitive decline.
Early surgical menopause linked to faster cognitive decline
The issue of the effect of menopause on women’s cognition, and whether hormone therapy helps older women fight cognitive decline and dementia, has been a murky one. Increasing evidence suggests that the timing and type of therapy is critical. A new study makes clear that we also need to distinguish between women who experience early surgical menopause and those who experience natural menopause.
Cognitive decline in old age related to poorer sleep
Recent research has suggested that sleep problems might be a risk factor in developing Alzheimer’s, and in mild cognitive impairment. A new study adds to this gathering evidence by connecting reduced slow-wave sleep in older adults to brain atrophy and poorer learning.
