New Screening Technique Makes Waves in The Quest for Earlier Diagnosis of Alzheimer’s Disease

How could the study of patients under anesthesia lead to a new way to diagnose Alzheimer’s disease? It could all come down to brainwaves. Patrick Purdon, PhD, a researcher with the Massachusetts General Hospital Department of Anesthesia, Critical Care and Pain Medicine, is investigating how changes in brainwave patterns could potentially detect early signs of ...

Reading the Unconscious Mind Under General Anesthesia

In September, eight researchers came to Massachusetts General Hospital to compete in our first-ever Art of Talking Science competition during HUBweek. Each researcher had four minutes to present their science to an audience of 200 people and a panel of judges, and then received feedback on how well they communicated the impact and significance of their work. Participants included scientists ...

Brown Seeks to Change The Way We Think About Anesthesia

Emery Brown, MD, PhD, and a team of collaborating investigators from Massachusetts General Hospital are hoping to make a fundamental change in the way anesthesiologists think about the process of sedation—one that changes the focus from the body to the brain.

Anesthesia: Who Knew What When?

“On October 16, 1846, at Massachusetts General Hospital, [William T.G. Morton] successfully administered ether to a surgical patient in a public demonstration. As acclaim was heaped upon Morton, [Horace] Wells unsurprisingly cried foul—but so did [Charles T.] Jackson. A bitter dispute rose all the way to Congress…” READ MORE

Studies Reveal How General Anesthesia’s Brain effects Differ in Older Adults and in Children

“We know even less about how anesthetic drugs influence brain activity in children, and the current standard of care for assessing the brain state of children under anesthesia calls only for monitoring vital signs like heart rate and blood pressure. This lack of knowledge is especially troubling, given recent studies suggesting an association between early childhood surgery requiring general ...
