Several studies suggest that post-operative cognitive decline in older adults is due to several factors:
It also seems that higher levels of cognitive function, higher levels of engagement in certain cognitive activities, and better cerebrovascular health, all protect against such decline.
Data from the Rush Memory and Aging Project has found that emergency and urgent hospitalizations are associated with an increased rate of cognitive decline in older adults.
In a series of experiments involving college students, drawing pictures was found to be the best strategy for remembering lists of words.
A Finnish study involving 338 older adults (average age 66) has found that greater muscle strength is associated with better cognitive function.
Data from over 11,500 participants in the Atherosclerosis Risk in Communities (ARIC) cohort has found evidence that orthostatic hypotension in middle age may increase the risk of cognitive impairment and dementia 20 years later.
A study involving 60 undergraduate students confirms the value of even a single instance of retrieval practice in an everyday setting, and also confirms the value of cues for peripheral details, which are forgotten more readily.
A Canadian study involving French-speaking university students has found that repeating aloud, especially to another person, improves memory for words.
A new MRI technique has revealed that it is the structural integrity of the
A new issue for parents to stress over is the question of whether reading digital books with your toddler or preschooler is worse than reading traditional print books.
A review of 39 studies investigating the effect of exercise on cognition in older adults (50+) confirms that physical exercise does indeed improve cognitive function in the over 50s, regardless of their cognitive status.
An extensive review of research looking at the effects of a single bout of exercise has concluded that:
A Canadian study involving 40 older adults (59-81), none of whom were aware of any major memory problems, has found that those scoring below 26 on the Montreal Cognitive Assessment (MoCA) dementia screening test also showed shrinking of the anterolateral

A study involving 18 volunteers who performed a simple orientation discrimination while on a stationary bicycle, has found that low-intensity exercise boosted activation in the visual cortex, compared with activation levels when at rest or during high-intensity exercise.
In Australia, it has beens estimated that 9% of people aged over 65, and 30% of those aged over 85 have dementia. However, these estimates are largely based on older data from other countries, or small local samples.
