We read with interest the Invited Commentary by Vasilevskis and Ely1 entitled “The Danger of Delirium” on the article by Gross and colleagues2 evaluating delirium and long-term cognitive trajectories in patients with dementia. We agree with the authors' indication on the need to preserve the “functional integrity of the brain,” and we want to highlight the importance to identify the most appropriate means to reach this objective, since we still currently lack information on the pathological basis explaining the negative long-term effects of delirium.
