“A recent study found that older soccer players experienced a 42% increase in brain-derived neurotrophic factor (BDNF)—a protein that supports brain growth and memory—after aerobic exercise, suggesting that staying active into old age offers meaningful brain benefits.”

“Branched-chain amino acids (like leucine) outcompete tryptophan for transport into the brain; however, exercise causes branched-chain amino acids to be taken up by muscle cells, thus, allowing tryptophan unabated transport into the brain to make serotonin.”

“Poor physical fitness as measured by VO2 max linked to deterioration of vital nerve fibers in the brain and memory decline. The study found that lower fitness levels were associated with weaker white matter, which in turn correlated with lower brain function.”

“These exercise-induced changes in the brain were passed on to offspring through microRNAs which help regulate gene expression. This study showed that paternal physical activity is a direct factor driving the offspring’s brain physiology and cognitive behavior.”

“Adenosine also activates receptors Adora1a and Adora2a on endothelial cells, which normally supports healthy relationships between brain activity and blood flow. > Problems arise with chronic activation, particularly in the brain, which is what happens with obesity, says Stranahan.”

“The limbic system – a complex system of nerves and networks in the brain – supports many brain functions, including memory, emotion, and learning. The olfactory system is the only sensory system directly linked to this critical brain region.”

“A new analysis asked whether this genetic difference shapes the relationship between blood omega-3 levels and early brain imaging markers. The study compared fasting blood omega-3 levels with two kinds of brain scans in 104 cognitively normal older adults.”

“These molecules can cross the blood-brain barrier and the placenta, potentially disrupting fetal neurodevelopment and impairing sensory processing abilities later in life. These impairments are often manifested in neuropsychiatric disorders such as autism or schizophrenia.”

“Sedentary behavior may have negative effects on brain health by decreasing neurogenesis, synaptic plasticity, neurotrophin production, angiogenesis, and by increasing inflammation.”

“The brain imaging studies revealed that particulate matter exposure was associated with white matter and hippocampal volume losses. These losses were particularly noticeable among women with the lowest levels of omega-3s in their red blood cells.”
