  • A large study of older adults with age-related macular degeneration found no cognitive benefit from taking omega-3 supplements, or supplements of lutein and zeaxanthin.

A large, five-year study challenges the idea that omega-3 fatty acids can slow age-related cognitive decline.

  • A large study of older adults (70+) found no cognitive benefit from a regular exercise program, compared to another social & mental intervention.
  • However, a subset of participants (those over 80, and those with poor physical function at the beginning of the study) did show improvement in executive function.
  • Participants in both programs showed no cognitive decline over the two-year period, suggesting both interventions were helpful.

A large, two-year study challenges the evidence that regular exercise helps prevent age-related cognitive decline.

More evidence for the benefits of the Mediterranean diet for fighting age-related cognitive decline comes from a large 5-year study. The study involved 960 older adults, whose cognitive change was assessed over 4.7 years.

A six-month pilot study involving 101 healthy older adults (65+), who were randomly put into one of three exercise interventions or a no-change control, has found that the exercise groups all showed significant improvement in visual-spatial processing and attention, with more improvement in visu

The root of age-related cognitive decline may lie in a reduced ability to ignore distractors. A new study indicates that older adults put more effort into focusing during encoding, in order to compensate for a reduced ability to hold information in working memory. The finding suggests a multi-pronged approach to improving cognitive ability in older adults.

I've reported before on the idea that the drop in

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.
