A review of meditation research reported in January last year concluded that there were insufficient good studies to allow us to say that meditation clearly improves attention and cognition.

In 2013 I reported briefly on a pilot study showing that “super-agers” — those over 80 years old who have the brains and cognitive powers more typical of people decades younger — had an unusually large

Three recent studies point to the importance of cardiorespiratory fitness for older adults wanting to prevent cognitive decline.

A study of younger and older adults indicates that memory search tends to decline with age because, with reduced cognitive control, seniors’ minds tend to ‘flit’ too quickly from one information cluster to another.

Evidence is accumulating that age-related cognitive decline is rooted in three related factors: processing speed slows down (because of myelin

A new study confirms the role slow-wave sleep plays in consolidating memories, and reveals that one reason for older adults’ memory problems may be the quality of their sleep.

Recent research has suggested that sleep problems might be a risk factor in developing Alzheimer’s, and in mild cognitive impairment.

A mouse study shows that weakening unwanted or out-of-date connections is as important as making new connections, and that neurological changes as we age reduces our ability to weaken old connections.

A new study adds more support to the idea that the increasing difficulty in learning new information and skills that most of us experience as we age is not down to any difficulty in acquiring new information, but rests on the interference from all the old information.

A large study finds that hearing loss significantly increases the rate of cognitive decline in old age.

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.

A smallish study suggests that the cognitive effects of menopause are greatest in the first year after menopause.

Being a woman of a certain age, I generally take notice of research into the effects of menopause on cognition.

Findings supporting dopamine’s role in long-term episodic memory point to a decline in dopamine levels as part of the reason for cognitive decline in old age, and perhaps in Alzheimer’s.

The

A honey bee study shows how old foraging bees quickly start to decline cognitively, and how this can be reversed in some if they return to more social domestic duties in the hive.

I often talk about the importance of attitudes and beliefs for memory and cognition. A new honey bee study provides support for this in relation to the effects of aging on the brain, and suggests that this principle extends across the animal kingdom.
