“Findings from a recent study in mice found that PF4, an exerkine derived from platelets, promotes the production of hippocampal precursor cells in the brains of older mice. Researchers injected PF4 into mice and assessed its effects on hippocampal neurogenesis (the growth of new brain cells).”

“Findings from a new study suggest that people with Parkinson's disease have defects that promote poor blood-brain barrier function, impairing angiogenesis and autophagy. The blood-brain barrier is a lining of epithelial (skin-like) cells that exchanges nutrients, waste, and signaling molecules.”

“While this research supports the connection between the gut microbiome and the brain, the mechanisms for how different types of gut bacteria affect the brain are still not known. It's an exciting time to be in this field of research!”

“Once in the brain, it caused the loss of dopamine neurons in animals.”

“A new study has found that a tiny region in the brain called the locus coeruleus may provide the link between openness and better cognitive health. People with greater locus coeruleus integrity demonstrated more openness and – interestingly – had higher intelligence.”

“Low BDNF concentrations are typical in psychiatric disorders but typically rise after antidepressant treatment and high omega-3 fatty acid doses. Exercise and DHA-rich diets also elevate BDNF, and some evidence suggests that BDNF mediates DHA's beneficial brain effects.”

“The study included 364 older adults, ranging from healthy people to those with subjective cognitive decline, mild cognitive impairment, or Alzheimer’s disease. Researchers assessed the thickness and volume of participants' brain regions associated with language and Alzheimer’s progression.”

“It has been shown that movement, especially at high speeds, not only engages motor control but also engages executive function, spatial navigation, and memory abilities. Over time, these linked cognitive demands may have beneficial effects on brain structure and function.”

“One strategy for measuring cognitive function is assessing functional connectivity – a proxy for brain network activity. Findings from a new study show demonstrate that older adults without dementia have greater functional connectivity in regions of their brains involved in executive control, language processing, and speech production compared to their younger counterparts.”

“At the end of the week-long study, the participants' blood cell glutathione levels increased 32 percent. The MRS scans revealed similar increases in the thalamus, a region of the brain involved in information processing and a key player in schizophrenia.”
