“People with higher levels of cortisol (a hormone linked to stress) in the blood performed worse on memory and other cognitive tasks and had smaller brain volumes than peers of the same age with average cortisol levels.”

“The investigators found that participants who took antibiotics for at least two months over the previous four years were more likely to perform worse on neuropsychological tests than participants who did not take antibiotics.”

“Several studies have shown that aerobic exercise causes a robust increase in brain-derived neurotrophic factor (BDNF), which increases the growth of new neurons and likely explains the increase in brain volume these people experienced.”

“A 28% lower risk of dementia and better scores on tests for memory and linguistic abilities was associated with a high intake of dietary phosphatidylcholine mainly from eggs and meat in men. Choline is an important precursor to the neurotransmitter acetylcholine which plays an important role in cognition.”

“A recent study demonstrates that alterations in serotonin levels during early life impair prefrontal cortex development, driving changes in the density and function of dendritic spines, the tiny structures on neurons essential for brain communication.”

“When the researchers looked at participants with fat measurements taken at three time points (at the start and end of the original trials, and later during this new study), lower long-term exposure to visceral fat was linked to better cognitive and memory scores later in life.”

“Exposure to air pollutants is associated with an increased risk of developing many health disorders, including heart disease, stroke, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.”

“The findings from this small study suggest that just one session of high-intensity resistance training has considerable influence on memory, highlighting its potential to promote cognitive health and neural plasticity.”

“Lactate often gets a bad rap due to its close association with lactic acid. But lactate plays a distinctly different and often-underappreciated role from lactic acid, serving as a fuel for the brain, ultimately supporting cognition and preventing age-related cognitive declines.”

“Six minutes of vigorous exercise increased brain levels of BDNF – a protein that may protect against Alzheimer's disease and other neurodegenerative conditions – as much as five times more than light exercise, a new study has found.”
