With surprising frequency, patients with severe brain injury can show clear signs of cognitive function on brain scans in response to requests to carry out complex mental work, even when they can’t move or speak, according to an international study co-led by Weill Cornell Medicine and NewYork-Presbyterian investigators.

The transition to menopause is marked by a progressively higher density of estrogen receptors (ER) on brain cells, a measure that remains elevated in women up to their mid-60s, according to a new brain imaging study led by researchers at Weill Cornell Medicine.

 A multi-center, phase 3 clinical trial has found that apixaban is no more effective than aspirin at preventing a second stroke in patients diagnosed with a milder, related condition called atrial cardiopathy, according to results reported by researchers at Weill Cornell Medicine, Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian.

A common type of brain bleed in older adults, known as subdural hemorrhage, is associated with the presence of amyloid deposits in cerebral blood vessels, according to a study led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and Yale School of Medicine.

Researchers at Weill Cornell Medicine have demonstrated how amyloid beta, a peptide associated with Alzheimer’s disease, can interact with a protein receptor on immune cells in the brain triggering a reaction that damages blood vessels and leads to neurodegeneration. 

Ambulance-based mobile stroke units (MSU) can reach patients faster to deliver clost-busting drugs that increase the likelihood of averting strokes and complete recovery compared with standard hospital emergency care, according to researchers at Weill Cornell Medicine, NewYork-Presbyterian, UTHealth Houston, Memorial Hermann-Texas Medical Center and five other medical centers across the United States.

Estrogen-based menopause hormone therapy for women in mid-life should be investigated more thoroughly as a potential strategy for preventing Alzheimer’s disease, the most common form of dementia, according to a new analysis from researchers at Weill Cornell Medicine.

Dr. Greta Strong, an assistant professor of community outreach teaching in the Department of Neurology at Weill Cornell Medicine, received the U.S. Presidential Lifetime Achievement Award.

A very subtle and seemingly random type of eye movement called ocular drift can be influenced by prior knowledge of the expected visual target, suggesting a surprising level of cognitive control over the eyes.

Cigarette smoking is associated with worse cognitive performance among people 60 years and older, and that association is broadly the same whether or not individuals have hypertension or diabetes.

New study by The Rockefeller University and Weill Cornell Medicine investigators illuminates the distributed nature of memory processing in the brain, and provides new insights into the process of memory recall, which is less understood than memory storage.

A new onset of a rapid or irregular heartbeat that develops after surgery, often within a few days, is associated with an increased risk for hospitalization for heart failure among patients undergoing both cardiac and noncardiac surgery, according to a new study by Weill Cornell Medicine and NewYork-Presbyterian investigators.

A group of immune cells that normally protect against inflammation in the gastrointestinal tract may have the opposite effect in multiple sclerosis (MS) and other brain inflammation-related conditions, according to a new study by Weill Cornell Medicine and NewYork-Presbyterian researchers.

Dr. Michael Kaplitt, a professor of neurological surgery at Weill Cornell Medicine and a longtime leader in developing cutting-edge surgical therapies for movement disorders, leads a team that has been awarded a three-year, $8.9 million grant from the Aligning Science Across Parkinson’s (ASAP) initiative. 

Stroke patients received clot-busting medication more quickly,and had better recoveries, when treated by an ambulance-basedmobile stroke unit (MSU) compared with standard emergency room (EMS) care.

Children with infantile spasms, a rare form of epileptic seizures, should be treated with one of three recommended therapies and the use of non-standard therapies should be strongly discouraged, according to a study of their effectiveness by a Weill Cornell Medicine and NewYork-Presbyterian investigator and collaborating colleagues in the Pediatric Epilepsy Research Consortium.

The degree to which the brain’s wiring aligns with its patterns of activity can vary with sex and age, and may be genetic, suggests a study published by Weill Cornell Medicine investigators. 

People who have experienced a cerebral hemorrhage or brain bleed have a two-fold increase in the risk of having an ischemic stroke (caused by an artery blockage) or heart attack, compared with members of the general population.

Last spring, as the COVID-19 pandemic hit New York City with full force, Dr. Daniel MacGowan, a neurologist specializing in neuromuscular disease, was asked to consult in a COVID recovery ward.

More than 50 doctors, nurses and other healthcare professionals from Cayuga Health in Ithaca have joined their Weill Cornell Medicine and NewYork-Presbyterian/Weill Cornell Medical Center counterparts to care for New Yorkers diagnosed with COVID-19.
