Cognitive Impact of Reduced Sun Exposure During Pandemic
Could reduced prenatal sun exposure be related to lowered cognitive ability in pandemic babies?
Blood-brain barrier breakdown is an early biomarker for human cognitive dysfunction (2019)
Our data show that individuals with early cognitive dysfunction develop brain capillary damage and BBB breakdown in the hippocampus irrespective of Alzheimer’s Aβ and/or tau biomarker changes, suggesting that BBB breakdown is an early biomarker of human cognitive dysfunction independent of Aβ and tau.
Microbiota from Young Mice Improve Cognitive Function in Older Recipients
“Conducting fecal microbial transplants from young mice to old mice, researchers were able to show a reversal of aging-associated differences and a slowing of cognitive impairments.”
Association Between Maternal Fluoride Exposure During Pregnancy and IQ Scores
“In this prospective birth cohort study, fluoride exposure during pregnancy was associated with lower IQ scores in children aged 3 to 4 years.”
Immune cells destroy healthy brain connections, diminish cognitive function in obese mice
“Obesity leads to cognitive impairment by activating microglial cells, which consume otherwise functional synapses in the hippocampus, according to a study of male mice published in JNeurosci.”
Studies show connection between diet, cognitive function
“…her data suggested that caloric restriction functioned as a sort of “fountain of youth” for aging rodents, whose neurovascular and metabolic functions were better than those of young mice on an unrestricted diet.”
Study shows how exercise generates new neurons, improves cognition in Alzheimer’s mouse
“A study by a Massachusetts General Hospital (MGH) research team finds that neurogenesis -inducing the production of new neurons – in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer’s disease.”
Higher omega-3 index associated with better brain function
“Children with the highest levels of total omega-3s and DHA were three and four times, respectively, more likely to pass at least one condition of the DCCS test of executive function than those with the lowest levels”
Probiotic use is a link between brain fogginess
“Probiotic use can result in a significant accumulation of bacteria in the small intestine that can result in disorienting brain fogginess as well as rapid, significant belly bloating, investigators report.”
In rats, perinatal exposure to phthalates impairs brain structure and function
“Male and female rats exposed in the womb and during lactation to plasticizing chemicals known as phthalates had significantly fewer neurons and synapses than those that were not exposed, researchers report in a new study. The phthalate-exposed rats had reductions in the size of their medial prefrontal cortex, a brain region that regulates behavior, and […]
