Immune-Compromised People with HIV, APOE4 Gene May Have a Compounded Risk for Alzheimer’s
WASHINGTON (February 22, 2021) — People living with the human immunodeficiency virus (HIV) who have a history of severe immunosuppression and at least one copy of the Alzheimer’s disease-related gene variant APOE4 might see a compounded adverse effect on the circuitry that impacts memory. This could eventually lead to an increased risk for dementia after […]

Art Installation Illustrates Dyslexic Brains at Work
(January 14, 2021) — When a person practices a skill, the neural representations in the relevant parts of the brain change, allowing the person to perform the skill better. Research by Guinevere Eden, PhD, a Georgetown University professor of pediatrics and the director of the Center for the Study of Learning, found that the same […]

Children Use Both Brain Hemispheres to Understand Language, Unlike Adults
WASHINGTON (September 7, 2020) — Infants and young children have brains with a superpower, of sorts, say Georgetown University Medical Center neuroscientists. Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain’s two hemispheres, youngsters use both the right and left hemispheres to do the same task. […]

Veterans Study Suggests Two Subtypes of Gulf War Illness
WASHINGTON (December 12, 2019) — Brain imaging of veterans with Gulf War illness show varying abnormalities after moderate exercise that can be categorized into two distinct groups — an outcome that suggests a more complex illness that previously thought. Researchers at Georgetown University Medical Center, using functional magnetic resonance imaging (fMRI), have shown the Gulf […]

Finding Upends Theory about the Cerebellum’s Role in Reading and Dyslexia
WASHINGTON (October 9, 2019) — New brain imaging research debunks a controversial theory about dyslexia that can impact how it is sometimes treated, Georgetown University Medical Center neuroscientists say. The cerebellum, a brain structure traditionally considered to be involved in motor function, has been implicated in the reading disability known as developmental dyslexia. However, this […]

Novel Brain Map Tracks Early Brain Atrophy From HIV Infection
MEDIA CONTACT:Karen Teberkm463@georgetown.edu WASHINGTON (March 28, 2019) — A new map of brain tissue in people with HIV shows atrophy in several areas including a primary neurocognitive control center where shrinkage and loss of function can be seen in scans before clinical symptoms appear. The map and other findings from researchers at Georgetown University Medical […]

Center for Translational Imaging to Capitalize on Georgetown’s History and Expertise in Imaging Science
(December 7, 2018) — The ability to peer inside the body to learn if something has gone wrong and if so, what, is one of the critical pillars of health care today, but as a team of researchers have long realized, the field of imaging provides a powerful way to reveal unimagined clues to better understand […]
