A large study has been performed to investigate the association between anaesthesia, surgery and onset of dementia, and to discover whether the risk of dementia increases after surgery with anaesthesia.
Patients aged 50 years and older, who had been anaesthetised between January 2004 and December 2007, were compared with a control group until December 2010 to identify dementia. Patients who received anaesthesia and surgery had an increased risk of developing dementia and a reduced interval before dementia diagnosis. The risk of dementia was increased in patients who had intravenous or intramuscular anaesthesia, regional anaesthesia and general anaesthesia. This nationwide, population-based study indicates that patients receiving anaesthesia and surgery have an increased risk of developing dementia.
