“Drugs commonly used to treat depression also reactivated autophagy in this brain region. Additional experiments indicated that autophagy helps regulate brain cell activity by breaking down excess glutamate receptors, which are often overactive in depression.”

“People with Parkinson's disease that received a growth factor (GDNF) experienced a 100% improvement in dopamine uptake in a key brain region involved in the disease compared to the placebo group which did not experience any change.”

“Although many observational studies are now linking air pollution to dementia it is difficult to establish causation. However, a growing body of animal studies are establishing causation between breathing in particulate matter and brain inflammation and atrophy.”

“Large quantities of herpes simplex virus I are commonly found in the autopsied brains of people who had Alzheimer's disease. The authors of the study exposed cultured human-induced neural stem cells to herpes simplex I virus for three days.”

“A comprehensive review of the science supporting exercise as a strategy to reduce symptoms of depression via modulation of brain-derived neurotrophic factor.”

“Pretty gnarly, right? The supplement they gave these advanced-brain-agers was shown to restore cognitive function in the animals and brain cell density and brain mass were maintained at levels comparable to young mice.”

“These microplastic-laden cells clogged capillaries in the brain, reducing blood flow and triggering neurological impairments in the mice. The blockages resembled tiny blood clots, highlighting a previously unknown way microplastics could harm brain function.”

“This was found in multiple studies including non-demented middle-aged adults, independent of their relationship to cardiovascular and cerebrovascular disease. Brain inflammation is thought to be a major mechanism leading to brain dysfunction.”

“Cannabis use may disrupt the delicate balance of brain chemicals like dopamine, a neurotransmitter critical for attention and motivation. Learn how to improve attention by leveraging the effects of dopamine in this episode featuring Dr. Andrew Huberman.”

“A recent cell study found that beta-hydroxybutyrate, a type of ketone, helps protect the brain by targeting toxic proteins for disposal. Researchers delivered beta-hydroxybutyrate to brain cells collected from mice and monkeys via an exogenous ketone ester.”
