Timely and optimal management of people with delirium, should be performed with identification of possible underlying causes, dealing with a suitable care environment and improving education of health professionals. All these can be important factors, which contribute to a decrease in adverse outcomes associated with delirium.http://journal.frontiersin.org/Journal/10.3389/fneur.2012.00101/fullAgedDeliriumdiagnosisetiologyPrevention & control |
