“A kind of Miracle-Gro for the brain, BDNF stimulates the hippocampus -- the brain's center of learning and long-term memory -- to sprout new neurons, and it increases connections between neurons. [...]”

“While no of this data proves causation, there is a growing body of research showing that excess refined sugar does increase inflammation which crosses the blood-brain barrier and acceleration brain aging. Regarding the diet soda, there have been studies linking artificial sweeteners to disruption of the gut microbiome which also causes inflammation which can lead to brain aging.”

“A subconcussive head impact is a minor blow to the head that does not cause immediate symptoms of a concussion but can still lead to cumulative brain damage over time. Athletes frequently sustain hundreds of these minor impacts each season, allowing them to accumulate unnoticed.”

“Before any training-like stimulation, the brain needed a slightly stronger magnetic pulse to activate the hand muscle after the nap. This suggests that the overall strength of communication between brain cells was lower after the nap than after staying awake.”

“To avoid the influence of taste or preference cues on brain activity, they infused glucose, lipids (fats), and water (as a control) directly into the participants' stomachs. Then they measured the participants' brain activities and dopamine release in the striatum, an area involved in reward and motivation.”

“[...] > Neuroimaging studies in patients taking corticosteroids have related a decrease of hippocampal volume and brain atrophy due to a reduced blood flow in areas of the brain responsible for cognitive functions.”

“They also underwent cognitive tests that evaluated their episodic memory and executive function. The brain scans revealed that iron levels increased markedly over time, and higher iron accumulation correlated with poorer cognitive function.”

“One of the major changes observed was a decrease in brain glutathione levels (the major antioxidant in the brain which helps prevent damage to neurons).”

“Some evidence suggests that problems with the brain's creatine system may play a role in this decline. A recent study found that creatine supplements improved brain energy use, reduced the buildup of Alzheimer's disease-related proteins, and boosted memory in mice.”

“These findings highlight the pivotal role of serotonin receptors in modulating the growth and plasticity of dendritic spines, underscoring their importance in the serotonin-driven development of the prefrontal cortex. Learn how vitamin D and omega-3 fatty acids influence serotonin levels and brain development in this open-access article coauthored by Dr. Rhonda Patrick.”
