This is an excellent presentation by Dr. Gerald Jogerst in Family Medicine at the University of Iowa. The presentation may take a while to load and appear on your screen. You might want to consider using different web browsers such as IE 9, Safari, Firefox, or Google Chrome. This is a very thorough discussion of the defining characteristics of delirium, dementia, and depression and what’s important about distinguishing among them. Even though Dr. Jogerst may not be able to pronounce “Haloperidol”, he’s correct that it’s the first choice of drug to treat agitation and behaviors that interfere with the evaluation and management of the medical problems that cause delirium. Most experts agree though, that Haloperidol is not the treatment for delirium. Identifying and reversing underlying medical causes of delirium is the treatment.
