Odour identification as a marker for postoperative cognitive dysfunction: a pilot study.

Anaesthesia - 1 Apr 2004

Rentowl P, Hanning C D

Abstract excerpt

The onset of postoperative cognitive dysfunction is delayed in some elderly surgical patients and the condition may persist. Increasing age is a risk factor for both postoperative cognitive dysfunction and dementia. Major surgery may unmask an underlying dementia; we report findings of a pilot study designed to inform this hypothesis. Impaired odour identification ability is a characteristic of the preclinical...
