Delirium is one of those terms whose meaning is universally recognized in a general sense, but its use in a medical context still needs clarification. The absent-minded professor who writers and filmmakers enjoy portraying maybe confused at times but he does not have delirium. We also expect that a player knocked out in a sporting event might awaken feeling a little confused, but they are not delirious. Delirium describes someone who has become disorientated, unable to remember basic personal information and be fully aware of what is going on around them. It may also be a symptom of dementia but this if this person quickly fell into this condition other health issues are probably involved.
Health experts recommend a simple test that anyone can use to see if someone they see confused might have delirium. Ask them for simple information that you expect every normal person to know. For example, you could ask for their name, how old they are, where they live, what day it is today, and other similar simple questions. If they do not respond or provide strange or confused answers, it gives grounds to suspect that they might have delirium.
