He has a surgical consult this month. He is 67 and with Dementia, newly diagnosed. In anyone's opinion should he continue with the surgery? If he does not have surgery he will continue on with his pain meds for the rest of his life and as now they are not doing their job because he has been taking them for about 6 years for other pain issues as well. Thanks.P.S. Will the anesthesia hasten his Dementia ?
