Delirium is a common and very serious neuropsychiatric syndrome.

Typically it affects older patients with multiple medical problems, in fact up to half of all elderly patients in the hospital will have an episode of delirium at some point, but being said it can affect anyone - even children, even though that’s much less common.

So, what is delirium exactly? Well let’s look at a quick example. Let’s say there is an elderly man with diabetes and heart disease, who comes into the hospital with pneumonia.

He might be slowly recovering, even about to go home, and then one evening things change all of the sudden. He might get really hyperactive, and by that I mean that he may get agitated or aggressive with the staff, mumble or say things incoherently, and have disorganized thoughts or even delusions, perhaps talking about things that haven’t happened or happened years ago. He might even hear or see things like hallucinations, and not know where he is or what he’s doing there.

We would call this an episode of delirium, and it can be really scary for him or someone who is taking care of him, especially the first time it happens because it can come out of the blue.

These are the symptoms of what we call hyperactive delirium.

But there’s also hypoactive delirium which is like the flip side of the coin.

As an example, you might have a woman with a history of chronic constipation who has recently come out of back surgery.

If she has hypoactive delirium she might feel suddenly sluggish and drowsy, less reactive and sullen, and might look withdrawn, perhaps because she’s scared of having hallucinations.

These symptoms of both hyperactive and hypoactive delirium can start pretty suddenly and can happen off and on over the course of a few hours to a few days, with some patients having what they call mix state delirium where they are sometimes having hyperactive symptoms and sometimes having hypoactive symptoms.

As you might guess, delirium symptoms can be really tiresome for a patient and can make them sleepy during the day, and keep them up at night - all of which causes massive disruption to a person’s life and to the lives of their friends and family.
