A study in which 64 sedentary older adults (aged 60-88) participated in a 12-week exercise program found that those who engaged in high-intensity interval training (HIIT) saw an improvement of up to 30% in memory performance while participants who engaged in moderate-intensity aerobic exercise s |
A study involving 30 previously physically inactive older adults (aged 61-88) found that a three-month exercise program reversed some brain atrophy. |
A long-running study following 387 Australian women found that regular exercise in middle age was the best lifestyle change they could make to prevent cognitive decline in their later years. |
A Canadian study involving 45,522 adults (30+) found that higher levels of physical activity, eating more fruits and vegetables, and having a BMI in the normal weight or overweight range were each associated with better cognitive function in both younger and older adults. |

In a study involving 594 patients with sports-related mild traumatic brain injury (mTBI), only 45% had made a clinical recovery (had no more symptoms) after 14 days. The finding challenges current belief that most people with a sports-related mTBI recover within 10 to 14 days |

A 2017 review of research has concluded that, although the number of studies into the cognitive effects of the cocoa bean is limited and has produced mixed results, on balance the evidence points to positive cognitive effects from regular intake of “cocoa flavanols”, as well as immediate benefit |
Data from the long-running Rush Memory and Aging Project, involving 960 participants who completed a food frequency questionnaire from 2004 to 2013, found that those who ate one daily serving of green, leafy vegetables had a slower rate of cognitive decline than people who rarely or never ate th |
A large, long-running Finnish study looking at the dietary habits of 2,497 men aged 42-60 has found that a high intake of dietary cholesterol was not associated with the risk of dementia or Alzheimer's disease, even among carriers of the ‘Alzheimer’s gene’ APOE4. |
A study involving 99 healthy older adults found that levels of monounsaturated fatty acids were associated with cognitive performance and the organization of the brain's attention network. |
