Psychiatrist, Geriatricians and Neurologists, usually, treat delirium; however treatment strategies vary widely among disciplines, due to differences in the practice guidelines and local applications of current knowledge among centers. An integration of their treatment approaches could offer important clinical advantages. To refer some differences, The American Psychiatric Association (APA) Guidelines (10) recommend treatment with antipsychotics for elderly patients. Where haloperidol is the gold standard, with a dose of 0.25 to 0.50 mg every 4 hours, although the dose may need to be increased for those patients severely agitated. There is no mention among all subtypes of delirium. This guideline recognizes the non-pharmacologic intervention as part of the treatment.
