Researchers in the Perelman School of Medicine at the University of Pennsylvania found that, across a variety of neurodegenerative diseases, cerebrovascular disease affecting circulation of blood in the brain was significantly associated with dementia. The researchers contend that people already...
The ability to maintain mental representations of ourselves and the world - the fundamental building block of human cognition - arises from the firing of highly evolved neuronal circuits, a process that is weakened in schizophrenia. In a new study, researchers at Yale University School of...
JAMA Neurology Study Highlights In a study of elderly patients, Natalie L. Marchant, Ph.D., of the University of California, Berkeley, and colleagues suggest there is no evidence that vascular brain injury (VBI) increases the likelihood of beta-Amyloid (Aβ) deposition, a diagnostic criterion...
There are a growing number of clues that immune and inflammatory mechanisms are important for the biology of schizophrenia. In a new study in Biological Psychiatry, Dr. Mar Fatjo-Vilas and colleagues explored the impact of the interleukin-1β gene (IL1β) on brain function alterations associated...
Efforts to understand how the aging process affects the brain and cognition have expanded beyond simply comparing younger and older adults. "Everybody ages differently. By looking at genetic variations and individual differences in markers of vascular health, we begin to understand that...
