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.

Possible treatment for working memory decline with age
A study comparing activity in the dorsolateral prefrontal cortex in young, middle-aged and aged macaque monkeys as they performed a spatial working memory task has found that while neurons of the young monkeys maintained a high rate of firing during the task, neurons in older animals showed slower firing rates. The decline began in middle age.
Long-term meditation fights age-related cognitive decline
Following on from research showing that long-term meditation is associated with gray matter increases across the brain, an imaging study involving 27 long-term meditators (average age 52) and 27 controls (matched by age and sex) has revealed pronounced differences in white-matter connectivity between their brains.
Folic acid tied to better grades in Swedish teens
Most research into the importance of folate and B12 levels has centered on seniors, and it does seem clear now that having adequate levels of these vitamins is important for maintaining cognitive functioning as you get older. Folic acid levels are of course also regarded as crucial when the brain is developing, which is why pregnant women are urged to take supplements, and why some countries fortify their bread with it. There is less research in the extensive ground between these two end-points.
Why our brains produce fewer new neurons in old age
It wasn’t so long ago we believed that only young brains could make neurons, that once a brain was fully matured all it could do was increase its connections. Then we found out adult brains could make new neurons too (but only in a couple of regions, albeit critical ones). Now we know that neurogenesis in the hippocampus is vital for some operations, and that the production of new neurons declines with age (leading to the idea that the reduction in neurogenesis may be one reason for age-related cognitive decline).
Moderate to intense exercise may protect the brain in old age
Another study showing the value of exercise for preserving your mental faculties in old age. This time it has to do with the development of small brain lesions or infarcts called "silent strokes." Don’t let the words “small” and “silent” fool you — these lesions have been linked to memory problems and even dementia, as well as stroke, an increased risk of falls and impaired mobility.
Religious factors may influence brain shrinkage in old age
The brain tends to shrink with age, with different regions being more affected than others. Atrophy of the hippocampus, so vital for memory and learning, is associated with increased risk of developing Alzheimer’s, and has also been linked to depression.
Childhood musical training helps auditory processing in old age
A number of studies have demonstrated the cognitive benefits of music training for children. Now research is beginning to explore just how long those benefits last. This is the second study I’ve reported on this month, that points to childhood music training protecting older adults from aspects of cognitive decline. In this study, 37 adults aged 45 to 65, of whom 18 were classified as musicians, were tested on their auditory and visual working memory, and their ability to hear speech in noise.
Benefits of childhood music lessons may extend into old age
A study involving 70 older adults (60-83) has found that those with at least ten years of musical training performed the best on cognitive tests, followed by those with one to nine years of musical study, with those with no musical training trailing the field.
Smaller life space linked to greater risk of cognitive decline
Growing evidence has pointed to the benefits of social and mental stimulation in preventing dementia, but until now no one has looked at the role of physical environment.
A study involving 1294 healthy older adults found that those whose life-space narrowed to their immediate home were almost twice as likely to develop the condition as those with the largest life-space (out-of-town). The homebound also had an increased risk of MCI and a faster rate of global cognitive decline.
Why it gets harder to remember as we get older
As we get older, when we suffer memory problems, we often laughingly talk about our brain being ‘full up’, with no room for more information. A new study suggests that in some sense (but not the direct one!) that’s true.
To make new memories, we need to recognize that they are new memories. That means we need to be able to distinguish between events, or objects, or people. We need to distinguish between them and representations already in our database.
