Abnormal forms of a brain-cell protein called tau, which have long been implicated in Alzheimer’s and other neurodegenerative disorders, may contribute to neurodegeneration earlier than was previously understood, by interfering with the normal dynamics of blood flow in the brain.
Neurologists traditionally have expected that patients who remain in coma after cardiac arrest have almost no chance of making a meaningful recovery if they fail to emerge from coma within a week.
The short-term risk of a second stroke following an initial minor stroke is roughly 60 percent higher for black patients compared with white patients, according to a study led by Weill Cornell Medicine and NewYork-Presbyterian researchers.
Immune cell activity in the brain differs between males and females in ways that may explain why some neurodegenerative diseases affect the sexes differently
Weill Cornell Medicine scientists have built the first global database of clinical trials testing a rapidly expanding approach to cancer treatment that involves genetically modifying immune cells to recognize specific targets on a patient’s cancer cells and attack them.
Dr. Costantino Iadecola, director of the Feil Family Brain and Mind Research Institute and the Anne Parrish Titzell Professor of Neurology at Weill Cornell Medicine, has been recognized as a 2019 Distinguished Scientist by the American Heart Association for his outstanding contributions to cardiovascular, stroke and dementia research.
A high-salt diet may negatively affect cognitive function by causing a deficiency of the compound nitric oxide, which is vital for maintaining vascular health in the brain, according to a new study in mice from Weill Cornell Medicine researchers.
In the roughly 100 years since Alois Alzheimer first described the devastating neurodegenerative disease that now bears his name, scientists have developed an increasingly sophisticated understanding of the brain.
Dr. Hagen Tilgner is exploring how faulty building instructions for brain cells may give rise to depression, schizophrenia, Alzheimer’s disease and more
A novel mechanism that regulates activity in the brain, discovered by Weill Cornell Medicine investigators, may help explain the origins of one common type of dementia.
While heart attacks that cause classic symptoms such as pressure and pain in the chest are an established risk factor for stroke because they can lead to blood clot formation, new research by Weill Cornell Medicine and NewYork-Presbyterian investigators indicates that heart attacks that have few, if any, recognized symptoms may also increase risk.
The chemical element selenium, an essential nutrient for humans and other animals, protects the brain after a stroke and may be a basis for future stroke therapies, according to a study from scientists at Burke Neurological Institute and Weill Cornell Medicine.
Weill Cornell Medicine has experienced dynamic growth in its research enterprise over the past five years, an achievement that underscores the institution’s mission to provide patients with the most advanced treatments and therapies.
Long-term spaceflight causes more changes to gene expression than shorter trips, especially to the immune system and DNA repair systems, according to research by Weill Cornell Medicine and NASA investigators as part of NASA’s Twins Study, which followed the only set of identical twin astronauts for more than two years.
The powerful but temporary benefits of ketamine against depression might be extended if the new brain-cell connections it promotes could be preserved, according to a new study.
Older adults with cancer are nearly 70 percent more likely to suffer a stroke or heart attack in the year prior to their diagnosis compared with peers without a cancer diagnosis in that same time period, according to new research by Weill Cornell Medicine, NewYork-Presbyterian and Memorial Sloan Kettering Cancer Center investigators.
Measuring brain activity in response to hearing a brief narrative can identify patients with severe brain injury who have preserved high-level cognition despite showing limited or no consciousness at the bedside, according to a study by Weill Cornell Medicine researchers.
A protein linked to both Alzheimer’s disease and a form of dementia increases the risk of cognitive impairment by reducing the number and responsiveness of blood vessels in the organ.
