In a recent animal study, researchers from the Brain and Mind Research Institute at Weill Cornell Medicine have found that epsilon toxin — produced by a bacterium found in the small intestine — may trigger the onset of MS and cause continuing symptoms. The study is published in The Journal of Clinical Investigation, ...

People with autism spectrum disorder can be classified into four distinct subtypes based on their brain activity and behavior, according to a study from Weill Cornell Medicine investigators.

The study, published March 9 in Nature Neuroscience, leveraged machine learning to analyze newly available neuroimaging data from 299 people with autism and 907 neurotypical people. They found patterns of brain connections linked with...

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, according to a study from investigators at Weill Cornell Medicine and NewYork-Presbyterian. The findings, published Dec. 6 in the Journal of Alzheimer’s Disease, underscore smoking’s adverse effect on...

The existence of such a brain-preserving state could explain why some patients wake up days or even weeks after they stop receiving ventilation, and it suggests that physicians should take these...
