A study looking at how 51 women performed on a test of their attention after they ate either a meal high in saturated fat or the same meal made with sunflower oil (high in unsaturated fat), found their performance was worse after eating the high-saturated-fat meal than after they ate the meal co

Analysis of data from the Age-Related Eye Disease Study (AREDS) and AREDS2, involving a total of around 8,000 older adults, has found that those with the greatest adherence to the Mediterranean diet had the lowest risk of cognitive impairment.

A study involving 110 lean and healthy students (aged 20-23) found that those randomly assigned to a high energy western-style diet for a week performed worse on a memory test compared to those who ate their normal healthy diet.

A study involving 5,907 older adults (average age 68) found that those who ate Mediterranean and MIND-style diets scored significantly better on cognitive tests than those who ate less healthy diets, with adherence to a brain-healthy diet correlating with cognitive benefit in a dose-response way

A study has found evidence that brain changes associated with aging can be seen at a much younger age than would be expected, in the late 40s. However, this process may be prevented or reversed based on dietary changes that involve minimizing the consumption of simple carbohydrates.

Data from the large and very long-running Framingham Heart Study has revealed that people who drink sugary drinks frequently are more likely to have poorer memory, smaller overall brain volume, and a significantly smaller

A double-blind, placebo-controlled study involving 40 older adults (aged 51-84) who had mild memory complaints, found that those given 90 milligrams of curcumin twice daily for 18 months experienced significant improvements in their memory and attention abilities.

A mouse study has found that a month of consuming cinnamon produced a significant cognitive improvement in poor-learning mice.

A mouse study found that high levels of alcohol over a long period of time were associated with high levels of a marker for inflammation, along with impaired cognition and motor skills.

A British study following 550 adults over 30 years from 1985 has found that those who reported higher levels of alcohol consumption were more often found to have a shrunken

Research using human cell cultures and mice suggests that those with an uncommon variation of the aldehyde dehydrogenase 2 gene (ALDH2) may be more at risk of Alzheimer's if they consume alcohol.

A 10-year study involving 19,887 middle-aged and older Americans, who completed surveys every two years about their health and lifestyle, has found that those who had a drink or two a day tended to show less cognitive decline, compared to non-drinkers.

  • A small study found that aerobic fitness was linked to the frequency of tip-of-the-tongue occurrences in older adults.

A small UK study involving 28 healthy older adults (20 women with average age 70; 8 men with average age 67), has found that those with higher levels of aerobic fitness experienced fewer language failures such as 'tip-of-the-tongue' states.

  • A large 10-year study investigating the benefits of a brain training program for older adults found that training designed to improve processing speed & visual attention in particular reduced dementia risk.

Findings from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) Study, which followed 2,802 healthy older adults for 10 years, has found that those who participated in computer training designed to improve processing speed and visual attention had a 29% lower risk of dev

  • A study found that physical fitness & arterial stiffness accounted for a third of the cognitive differences between older adults, completely erasing age as a factor.

An Australian study involving 102 older adults (60-90) has concluded that physical fitness and arterial stiffness account for a great deal of age-related memory decline.

  • A long-running study found older adults who moved more were less likely to develop dementia, even when they had brain pathologies characteristic of dementia.

A long-running study involving 454 older adults who were given physical exams and cognitive tests every year for 20 years has found that those who moved more than average maintained more of their cognitive skills than people who were less active than average, even if they have brain lesions or b

  • A large, long-running study has found older adults with a slower walking speed were more likely to develop dementia in the next decade.
  • Another long-running study has found that slowing over 14 years was linked to brain atrophy in the hippocampus, and cognitive impairment.

Data from the English Longitudinal Study of Aging, in which nearly 4,000 older adults (60+) had their walking speed assessed on two occasions in 2002-2003 and in 2004-2005, those with a slower walking speed were more likely to develop dementia in the next 10 years.

  • A study found that older adults remembered names better after moderately intense exercise.
  • A large, long-running study found that each hour of light physical activity per week was linked to less brain atrophy.
  • Similarly, another long-running study reported that higher levels of lifestyle physical activity were associated with less brain atrophy.

Exercise activates brain networks in older adults

A study involving healthy older adults (55-85) found that recall was better after a session of moderately intense exercise, and several crucial brain regions showed greater activation.

  • A small study has shown that those who show the biggest brain benefits after a single exercise session also show the biggest long-term gains from a training program.

A small pilot study, in which participants had brain scans and

  • A mouse study has found that a hormone released during physical activity protects synapses in the hippocampus.
  • Another mouse study found that short bursts of exercise promotes an increase in synapses in the hippocampus.
