Study shows general anesthesia increases dementia risk for elderly

Published

on

General anaesthesia for the elderly boosts the risks of dementia by more than a third, according to a study by French doctors released on Friday.

Researchers led by Francois Sztark at the University of Bordeaux in southwestern France analysed data from a long-term study into cognitive decline covering 9,300 elderly people in three French cities.

The volunteers — average age 75 — were interviewed when they were recruited into the study and then two, four, seven and 10 years afterwards.

The data showed a link between the onset of dementia and a general anaesthetic that had been administered two or three years before.

Those who had received general anaesthesia were 35 percent likelier to develop dementia symptoms by the next follow-up interview compared with counterparts who had not had general anaesthetic.

Previous work has already highlighted a condition called post-operative cognitive dysfunction, or POCD, in which an elderly patient who undergoes major surgery also goes into mental decline relatively soon afterward.

The reasons for this, though, are unclear. Some experiments suggest that various anaesthetics inflame neural tissues, causing protein plaques and tangles to develop that are precursors of Alzheimer’s disease.

The research was released at a congress in Barcelona, Spain, of the European Society of Anaesthesiology.

“These results are in favour of an increased risk for dementia several years after general anaesthesia,” Sztark said in a press release, adding that patients who underwent major surgery needed long-term support.

2020 Election

Mass rallies, crazy decisions, grandiose posturing: This is what living in a dictatorship feels like

Published

on

Another week of shaking our heads and wondering how much longer we can survive him. Yet again, Donald Trump overwhelmed practically everything with the force of his obscene personality, running his mouth and his thumbs even while he was failing to run the country in any sort of conventional sense. He doesn’t actually do anything, but he dominates everything. Living in America today is like being trapped in a room with him — no doors, no windows, no exits, only Trump and the sound of Trump and the hideous image of Trump, all day, every day, for day after day after day.

Trump officials furious with NRA over ‘dick move’ leak of LaPierre phone call: report

Published

on

President Donald Trump originally appeared interested in strengthening federal background check laws in the wake of deadly mass shootings in El Paso, Texas and Dayton, Ohio. Then, after a phone conversation with National Rifle Association CEO Wayne LaPierre on Tuesday, Trump reportedly assured him that background checks were "off the table" and pivoted to discussing anything but guns.

It was a depressingly familiar moment for Trump, who also previously headfaked toward some minor gun control reforms after the Parkland school shooting and quickly walked them back.

Trump mulling ‘uniquely dystopian’ proposal to use AI to identify mental health issues as risk factors for gun violence

Published

on

One critic called the proposal, which expands on Trump's claim that mental illnesses, not guns, are to blame for gun violence, "nothing less than chilling."

In keeping with his insistence that people with mental illnesses, and not the wide availability of guns, are to blame for the epidemic of gun violence and mass shootings in the U.S., President Donald Trump is reportedly considering a new project aimed at detecting mental health issues to stop shootings before they happen.

As The Washington Post reported Thursday, the Trump administration has worked with Bob Wright, a close friend of Trump's and his collaborator on the reality show "The Apprentice," to develop a proposal for a new federal agency that would be called the Health Advanced Research Projects Agency (HARPA), within the Health and Human Services Department.
