“Typically characterized by sensory, cognitive, and emotional experiences, dreams share many similarities with hallucinations. Scientists formerly believed that dreams only occurred during the rapid eye movement, or REM, stage of sleep, but recent research indicates that they can occur at any time during sleep.”

“00:34:40 - Repeated traumatic brain injury has cumulative neuroinflammatory effects in the brain over years, including amyloid-beta plaque and tau tangle formation. Study. 00:44:00 - A variant of the APOE gene increases risk of developing Alzheimer’s disease as much as 15-fold.”

“The study was done in mice and focused on providing the essential micronutrients (B6, B12, folate, and methionine) which must be obtained through diet. Early-life stress was shown to reduce the levels of these micronutrients and this led to lasting negative effects on learning and memory in adulthood.”

“Omega-3 and vitamin B12 supplementation in rats increased nerve growth factor (NGF), which helps grow new brain cells and boosts acetylcholine levels and improved cognitive performance after 2 generations in rats.”

“In a small randomized trial of adults aged 60 to 80, five grams per day during 12 weeks of supervised resistance training increased lean mass more than placebo plus training; measured strength and bone outcomes did not significantly differ between groups.”

“Participants with cardiovascular disease scored lower on memory tests initially, but after taking the multivitamin/multimineral supplements for a year, their memory scores improved, reaching a level comparable to those without cardiovascular disease.”

“All participants had normal cognition at the beginning and underwent a hearing test and a self-assessment of their hearing. The researchers compared the number of new dementia cases over time with each participant's hearing status at the start of the study.”

“"The brain is especially vulnerable to dietary influences during critical periods of development, like adolescence," remarked a corresponding author of the study. "Consuming a diet high in added sugars not only can lead to weight gain and metabolic disturbances, but can also negatively impact our neural functioning and cognitive ability."”

“Another study has shown that obesity epigenetically alters 500 different genes in human sperm DNA including genes involved in cognition. Likewise, several animal studies have shown that maternal obesity epigenetically changes genes involved in brain function.”

“Individuals who drank green tea, oolong tea, or black tea 4x/week for 25 yrs had more efficient brain connections in certain brain regions compared to non-tea drinkers. The same research group previously found that tea consumption was linked to a 50% reduction in cognitive decline.”
