A new neuroimaging study has identified distinct structural brain differences in individuals with psychopathy, particularly those with high antisocial traits. Reduced volumes were found in subcortical and cortical areas involved in emotion, decision-making, and social behavior.
Robotic Heart Transplant Marks Surgical Breakthrough
Surgeons have performed the first fully robotic heart transplant in the U.S., using advanced robotic tools to avoid opening the chest. This technique involved precise incisions and accessing the heart through the preperitoneal space, preserving the chest wall.
Neighborhood Disadvantage Linked to Alzheimer’s Biomarkers and Inflammation
Living in disadvantaged neighborhoods may increase the risk of Alzheimer’s disease by elevating biomarkers associated with inflammation and neurodegeneration. A long-term study of 334 older adults found higher levels of tau and YKL-40, biomarkers linked to Alzheimer’s and brain inflammation, in people from less advantaged areas.
Staying Active Slows Cognitive Decline
Regular physical activity isn’t just good for the body—it protects the brain as we age. A 16-year study of over 13,000 adults found that sustained physical activity significantly slowed cognitive decline.
