Research conducted at the University of Kentucky College of Medicine suggests that higher intake of specific nutrients is associated with lower brain iron concentration and better cognitive performance in older adults.

Collaborative research between the University of Kentucky and the University of Southern California (USC) suggests that a noninvasive neuroimaging technique may index early-stage blood-brain barrier (BBB) dysfunction associated with small vessel disease (SVD). Cerebral SVD is the most common cause of vascular cognitive impairment, with a significant proportion of cases going on to develop dementia. BBB dysfunction represents a promising early marker of SVD because the BBB regulates a number of important metabolic functions, including clearance of toxic brain substances.

LEXINGTON, Ky. (May 5, 2021) - Collaborative research between the University of Kentucky (UK) and University of Southern California (USC) suggests that a noninvasive neuroimaging technique may index early-stage blood-brain barrier (BBB) dysfunction associated with small vessel disease (SVD). Cerebral SVD is the most common cause of vascular cognitive impairment, with a significant proportion of cases going on to develop dementia. BBB dysfunction represents a promising early marker of SVD because the BBB regulates a number of important metabolic functions, including clearance of toxic brain substances.
Advanced BBB dysfunction can be detected with neuroimaging measures such as positron emission tomography (PET) scanning and dynamic contrast-enhanced (DCE) MRI. However, these methods require exposure to radiation or contrast agents and may only detect moderate to advanced stages of BBB tissue disruption. The UK-USC study used a novel, noninvasive MRI method called diffusion
