“However, the rs-fMRIs revealed that the different intensities affected different parts of their brains. The low-intensity exercise turned on the activity of brain networks involved in cognitive function and attention processing.”

“To tackle that question, scientists combined brain-scan data from several countries and analyzed them together to see whether different drugs produce similar changes in the brain. The researchers carried out a mega-analysis, meaning they pooled individual brain-scan data from multiple earlier studies and reanalyzed them together.”

“Loss of blood-brain barrier integrity increases the risk of many neurodegenerative diseases, including dementia and Alzheimer's. A 2021 study found that having a higher omega-3 index preserves the blood-brain barrier and maintains cognitive function in older adults.”

“These losses contribute to age-related cognitive decline and loss of neuroplasticity, the brain's ability to change and adapt to new exposures. Findings from a 2020 study suggest that having greater cardiorespiratory fitness helps prevent age-related brain volume losses.”

“Deeper brain regions (subcortical areas) such as the basal ganglia and hippocampus did not show clear differences in choline or NAA. The other measured brain chemicals did not show reliable differences between people with anxiety and healthy volunteers.”

Dr. Rhonda Patrick discusses sunscreen safety, HIIT & brain health, diet, omega-3s, urolithin A, sulforaphane, homocysteine, peptides, and CoQ10.

“Whereas low-intensity exercise activated brain networks involved in cognition control and attention processing, high-intensity exercise activated networks involved in mood. These findings support other data indicating that exercise benefits brain health and suggest that exercise may be a promising modality for use in improving cognitive function and in treating mood disorders.”

“The mice with kidney disease had twice as many microbleeds in their brains as healthy mice and showed signs of increased blood-brain barrier permeability. Fifty percent of the people who had kidney disease had microbleeds, whereas just 10 percent of those who were healthy had microbleeds.”

“In addition, more serious dysfunction in brain glucose utilization was associated with the manifestation of disease symptoms like memory issues during life. This study also found that glucose transporters in neurons were also low in Alzheimer's patients which could explain why glucose is not being used well in neurons.”

“Interestingly, dietary consumption of omega-3 fatty acids may help [protect the brain ) from damage associated with PM2.5 exposure. Learn more about the health effects of omega-3 fatty acids in this episode featuring Dr. Bill Harris. Link to study abstract.”
