Recently there was an article in the Times News paper about a study carried out by French Researchers. They selected 9000 people over the age of 65 and found that within a decade 632 developed dementia. Out of this number they noted that 22.3% had received a general anaesthetic and 18.7% had not. They were going to present a paper at a conference in Barcelona to say that older people who had received at least one general anaesthetic were 35% more likely to develop dementia.

Although some feel that the link was a little vague, it is worth remembering that the elderly patients do carry some risk during gen. anaesthesia. This topic may need further research and study.
