Alzheimer’s Disease

Researchers at Colorado College may have identified a new neuropathological hallmark of Chronic Traumatic Encephalopathy (CTE). Their findings, published in the Journal of Comparative Neurology, describe overall dendritic atrophy across cortical neurons and greater morphological variability in CTE brains compared to controls.   A neurodegenerative disorder characterized by late-onset symptoms like depression, confusion, and memory loss, CTE is caused by repeated impacts to the brain. The disease...

Researchers at Stanford University are working on figuring out how it happens.   In their study, published in the journal Brain Structure and Function, scientists in Dr....
