A specific toxin-producing gut bacteria may be responsible for both triggering the onset of multiple sclerosis (MS) and ongoing disease activity.

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.

COVID-19 patients placed on ventilators can take a long time to regain consciousness. New research from Weill Cornell Medicine, NewYork-Presbyterian, MIT, and Massachusetts General Hospital is now illustrating that these delays may serve a purpose: protecting the brain from oxygen deprivation.

Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson’s disease through a cellular waste-ejection process, suggests a new study led by Weill Cornell Medicine researchers.

The psychedelic drugs LSD and psilocybin activate serotonin receptors on brain cells in a way that reduces the energy needed for the brain to switch between different activity states, according to a study led by Weill Cornell Medicine researchers.

Six Weill Cornell Medicine postdoctoral associates, instructors and junior faculty seeking to pursue independent research careers have received 2022 JumpStart Career Development awards.

Multiple changes in brain cells during the first month of embryonic development may contribute to schizophrenia later in life.

Depression is the most common mental illness as well as the number one cause of disability among people between the ages of 15 and 44. And for millions of sufferers, antidepressants have literally saved lives that could otherwise have been lost to suicide. 

The transition from pre- to post-menopause, with its steep decline in estrogen production, involves myriad changes to brain structure, brain-region connectivity, and brain energy consumption, though many of these changes are only temporary, a study led by researchers at Weill Cornell Medicine has found.

Women become more susceptible to hypertension as they approach menopause, and now a preclinical study led by researchers at Weill Cornell Medicine’s Feil Family Brain and Mind Research Institute suggests that this “perimenopausal” hypertension may be driven by declines in estrogen signaling in a brain region called the hypothalamus—and may be preventable with estrogen-like treatments.
