“A study in mice showed that removing gram-negative bacteria in the gut decreased the number of brain lesions in mice that were genetically susceptible to them. These type of bacteria release endotoxin (also called LPS) and this stimulates a very strong immune response leading to uncontrolled inflammation.”

“Previous research demonstrates that insulin resistance reduces brain volume and cognitive function in middle-aged adults. Results of a new study demonstrate that insulin interacts with dopamine to modulate reward-based behavior and whole-body metabolism.”

“While brain aging is an inevitable part of growing older, lifestyle factors, particularly diet, can influence the rate at which this aging occurs. A recent study found that older adults with diets rich in omega-3 fatty acids, antioxidants, and vitamins demonstrate slower brain aging and better performance on cognitive tests.”

“If confirmed, this vesicle-based transport system could help explain how physical stress rapidly reshapes communication between blood, immune cells, and the brain. In this clip, I discuss how vigorous exercise improves heart and brain health, enhances focus, and provides anti-cancer benefits.”

“The researchers also observed a drop in the resting brain connections among neurons managing actions, beginning around middle age. This drop in connections became even more pronounced when the mice were doing tasks, suggesting that the brain's ability to retain thoughts might weaken with age.”

“Additionally, I discuss how meditation has been shown to buffer against these negative effects on the brain and body by decreasing rumination, increasing gamma wave production, neuroplasticity, brain volume, and telomerase activity.”

“Poor blood flow to the brain, a common feature of aging, is associated with an increased risk of stroke and cognitive dysfunction. A recent study demonstrated that exercise improves brain blood flow and improves cognitive function in older adults.”

“Estrogen may protect the brain against autism. Children with autism have fewer estrogen receptors in their brains than children without the disorder, a 2014 study found. The children had low brain levels of proteins involved in estrogen signaling, as well.”

“Evidence suggests that ketones increase blood flow to the brain and improve memory and brain function in certain contexts. Learn more about the brain benefits of ketones in this clip featuring Dr. Dominic D'Agostino. Read study abstract and highlights.”

“A new study demonstrates that dietary consumption of omega-3 fatty acids may help protect the brain from damage associated with exposure to particulate matter in air pollution. Particulate matter is a mixture of solid particles and liquid droplets.”
