Lifestyle Effects on Memory & Cognition

Latest news

  • A review of research has confirmed the benefits of at least moderate exercise to fight age-related cognitive decline, with different benefits for aerobic exercise and strength training.

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.

  • A review of research has concluded that even a single bout of physical activity can have significant positive effects on people's mood and cognitive functions.

An extensive review of research looking at the effects of a single bout of exercise has concluded that:

  • Regular exercise has been found to reduce brain shrinkage in those with mild cognitive impairment.

A study involving 35 adults with

  • A small study found that low-intensity exercise significantly boosted activation in the visual cortex above what occurred during rest or high-intensity exercise.

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.

  • A large study adds to evidence that caffeine helps older women fight cognitive impairment and dementia.
  • This is supported by two animal studies showing precisely how caffeine is valuable for keeping the brain healthy.

Data from the Women's Health Initiative Memory Study, involving 6,467 postmenopausal women (65+) who reported some level of caffeine consumption, has found that those who consumed above average amounts of coffee had a lower risk of developing dementia.

  • A study of younger adults adds to evidence that higher BMI is associated with poorer cognition, and points to a specific impairment in memory integration.

A small study involving 50 younger adults (18-35; average age 24) has found that those with a higher BMI performed significantly worse on a computerised memory test called the “Treasure Hunt Task”.

  • A small study adds to evidence that walking improves memory in older adults, and indicates that this is particularly helpful for memory tasks the seniors find challenging.

A small study that fitted 29 young adults (18-31) and 31 older adults (55-82) with a device that recorded steps taken and the vigor and speed with which they were made, has found that those older adults with a higher step rate performed better on memory tasks than those who were more sedentary.

  • B vitamins can help many older adults with mild cognitive impairment, but only if they have good levels of omega-3 fatty acids.

A study involving 266 people with mild cognitive impairment (aged 70+) has found that B vitamins are more effective in slowing cognitive decline when people have higher omega 3 levels.

  • A small study shows that it's not only daily biological rhythms that affect brain activity, but longer seasonal ones also.

A sleep study involving 28 participants had them follow a controlled sleep/wake schedule for three weeks before staying in a sleep laboratory for 4.5 days, during which time they experienced a cycle of sleep deprivation and recovery in the absence of seasonal cues such as natural light, time inf

  • The Mediterranean diet is the diet most associated with cognitive and health benefits in older adults.
  • A new study has found larger brain volumes among those following this sort of diet, equivalent to that of brains five years younger.
  • Much of this was associated with two components of the diet in particular: eating fish regularly, and eating less meat.

Another study adds to the growing evidence that a Mediterranean diet is good for the aging brain.
