“Cognitive decline and associated memory loss are common features of aging, affecting approximately 16 million people living in the United States. A recent study found that high-intensity interval training improves memory in older adults.”

“From the article: > To determine why more aerobically fit individuals have better memories, scientists used magnetic resonance elastography (MRE), which measures the elasticity of organs, and found that fit individuals had a firmer, more elastic hippocampus—a region of the brain associated with memory. View full publication.”

“A recent study found that engaging in a single session of high-intensity resistance training enhanced memory capabilities. The study involved 60 young, healthy adults who took memory tests and underwent resting-state functional magnetic resonance imaging of their brains.”

“The effects of lost sleep on memory may depend partly on how well brain cells control inflammation and maintain their energy supply. Researchers tested whether urolithin A, a compound made by gut microbes from food components, could protect memory in mice when given before sleep deprivation.”

“One week after birth, mothers had a typical 25(OH)D level of 27.5 ng/mL in the routine-dose group compared with 41.9 ng/mL in the higher-dose group. Children in the higher-dose group had modestly higher verbal and visual memory function scores than those in the routine-dose group.”

“Deep, slow-wave sleep – the non-REM form of sleep – preps the brain for the input and storage of information to facilitate the formation of memories. But during REM sleep – the time when we dream – the brain fuses all those newly formed memories with a lifetime of stored experiences and associations, allowing them to coalesce and build novel new connections.”

“They also analyzed genetic markers related to brain function in both groups. Mice with active grandfathers had better memory recall, particularly in tasks requiring spatial (recalling locations) and non-spatial (recalling facts and events) memory.”

“Recalling our dreams depends on whether we are awakened shortly after the dream has occurred, which allows the brain to commit the dreamed experience to memory. Anecdotal accounts suggest, however, that dreams are already remembered – as evidenced by later recall of a dreamed experience, days or even weeks after it occurred.”

“FTA: > Many studies have linked more sleep to better memory, but new research in fruit flies demonstrates that extra sleep helps the brain overcome catastrophic neurological defects that otherwise would block memory formation, report scientists.”

“The IL-4 also prevents macrophages from releasing pro-inflammatory cytokines during stress that inhibits brain-derived neurotrophic factor (BDNF), which supports learning and memory. The disruption of BDNF during periods of stress disrupt the ability to learn and form memories. In other words, the IL-4 helps with learning under stressful situations.”
