As with all things ALZ, Teri, there is no one size fits all answer. What seems to have been common in the reports here over the PST few years has been a recovery over a few days. Then there have been some who just bounced back, as Jackie did after day surgery, and others who have taken a permanent step. Of course after hospitalisation it isn’t easy to distinguish between anaesthetic impact and disruption impact.

Great research, Robert. I liked the Australian paper linked from your second reference. Not surprisingly it matches the advice on the UTAS Understanding Dementia programme. I’m currently doing their Understanding Traumatic Brain Injury programme. I’d like to ask a doctor if anaesthetic induces a diffuse mild brain injury. The consequences sound very similar. S.

Teri, the US Alzheimer’s Association also has useful information on this question:
