UA psychologist Lee Ryan and her collaborators have proposed a precision aging model designed to help researchers better understand and treat age-related cognitive decline on an individual level.
Gladstone scientists uncover new gatekeeper function of anti-aging molecule
A study carried out in mice may help explain why dieting can be an inefficient way to lose weight: key brain cells act as a trigger to prevent us burning calories when food is scarce.
Bacteria in the gut microbiome drive the formation of cerebral cavernous malformations (CCMs), clusters of dilated, thin-walled blood vessels in the brain that can cause stroke and seizures, according to new research published this week in Nature by researchers from the Perelman School of Medicine at the University of Pennsylvania. Led by Mark Kahn, MD, a professor of Cardiovascular Medicine, the team’s research suggests that altering the microbiome in CCM patients may be an effective therapy for this cerebrovascular disease.
Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia. The results are now presented in the journal Nature Medicine.
