“Between the ages of 30 and 40 years, the connections between cells in a person's brain begin to diminish, causing the brain to shrink in volume. The rate of shrinkage increases as a person reaches the age of 60, impairing thinking, memory, and executive function.”

“The method by which this area was found to be critical is particularly interesting. FTA: >Saper analyzed a dataset of almost 1,000 subjects who had entered into a memory and aging study back in 1997, when they were all healthy 65-year-olds.”

“Evidence suggests that carriers of the Met allele (Met/Met or Val/Met genotype) have reduced hippocampal function, poor episodic memory, and decreased exercise-induced secretion of BDNF.”

“In addition, both groups demonstrated elevated levels of various neurotransmitters, including serotonin, norepinephrine and others, in brain tissue, along with changes in the expression of key proteins related to neural signaling.”

“They found that repeated mild blows to HSV-1-infected tissues reactivated the virus, triggering inflammatory processes in the brain and driving the buildup of amyloid-beta and phosphorylated tau—proteins linked to brain damage and memory loss.”

“They identified statistical connections between tau and amyloid proteins (hallmarks of Alzheimer's), iron levels, and cells in the hippocampus, a brain region crucial for memory. These findings indicate that iron plays a critical role in Alzheimer's pathology, but exercise can mitigate some of these effects.”

“The default mode network is a collection of interconnected neural structures involved in attention and focus. Disturbances in default mode network connectivity are associated with poor working memory, reduced performance, and work-related productivity losses.”

“> "We knew that estrogen affects the activity of many genes throughout the genome," [...] "But if you look at the estrogen-modulated sites that are also associated with PTSD, just one pops out." > That site is located in a gene called HDAC4, known to be critical for learning and memory in mice.”

“They measured cerebral blood flow and levels of hyperphosphorylated tau in the mice's brains. After the mice had eaten the high salt diet for 12 weeks, levels of hyperphosphorylated tau increased. The mice showed difficulty in recognizing new objects, and their spatial memory waned.”

“They found that the vesicles reduced inflammatory activity in brain cells, decreased levels of amyloid-beta plaques and phosphorylated tau (hallmarks of Alzheimer's), and improved memory and mood in the mice.”
