“The findings from this small study suggest that short-term cold exposure improves mood by enhancing brain connectivity in regions associated with mood. These benefits may arise from the effects of norepinephrine, a neurotransmitter involved in vigilance, focus, attention, and mood.”

“Synapses are junctions between neighboring neurons, where the exchange of electrical signals and neuronal communication occurs. Synaptic formation and integrity are necessary for the establishment and maintenance of the brain’s neural networks and the precision of its circuitry.”

“Between 5 and 16 years later, the participants underwent detailed testing, including brain and abdominal MRI scans to assess brain structure and fat distribution, along with standard tests of memory and thinking. Participants with more visceral fat generally had lower scores on a test of overall thinking ability, particularly among those with higher brain volume measures.”

“These findings underscore the risks associated with even mild brain injury. Some evidence suggests that lactate and ketones may be beneficial in treating brain injury. Learn more in this clip featuring Dr. Dominic D'Agostino.”

“Brain aging begins long before memory problems appear, but researchers still debate when lifestyle changes can measurably influence brain structure. A randomized clinical trial tested whether an aerobic exercise program that matches common activity recommendations can alter an MRI-derived estimate of brain aging in early and midlife adults.”

“Then the participants underwent magnetic resonance spectroscopy (MRS) to assess their NAA levels. The MRS scans revealed that participants with less body fat and higher levels of cardiorespiratory fitness had higher levels of NAA in the white matter of their brains.”

“Findings from a 2018 study demonstrate that dancing counteracts the harmful effects of aging on the human brain. Previous research has demonstrated that dancing simultaneously challenges sensory, motor, and cognitive aspects of brain function.”

“Exercise boosts brain health, but what kind of exercise provides the greatest benefit? A recent study found that high-intensity exercise improved cognitive function and maintained brain volume in older adults—with effects lasting five years or more.”

“Alzheimer’s disease is a common neurodegenerative disorder affecting an estimated 24 million older adults worldwide. Researchers believe the disease is caused by toxic levels of beta-amyloid protein aggregates in the brain that impair neuronal function and trigger cognitive decline.”

“For example, disruption in deep sleep is highly pronounced in people with Alzheimer's disease and typically precedes diagnosis. Glymphatic activation has also been shown to play a key role in the transport of biomarkers of traumatic brain injury (TBI).”
