Perioperative cognitive disorders. Response to: Postoperative delirium portends descent to dementia

Editor—We read with great interest the recent editorial by Aranake-Chrisinger & Avidan.¹ We were pleased to see that this editorial contains terminology developed over several yr by the multi-disciplinary International Perioperative Cognition Nomenclature Working Group. At the same time, we were surprised and disappointed that the terminology is presented before the official release (in the British Journal of Anaesthesia as well as Anesthesia & Analgesia, Canadian Journal of Anesthesiology, Acta Anaesthesiologica Scandinavica, Journal of Alzheimers Disease and Anesthesiology),² without the necessary definitions or attributions. This was particularly surprising given the senior author of the editorial was privy to the work of this group and reviewed final drafts of the manuscript. We presume this oversight simply reflects enthusiasm for adopting this new nomenclature.
