It can also be a result of head injury. Delirium is common after surgery, especially for adults over age 65. Delirium can result from certain drugs use such as marijuana, cocaine, alcohol, or prescription medications. It can also occur when people suddenly stop taking drugs or medications. If you have been on a medication for some time, talk with your healthcare provider before you stop.
Delirium can be very scary, but it is temporary.
It may last from hours to days. Older adults and children are more likely to have delirium when they are ill. Delirium is not the same thing as dementia. An older person with delirium should recover completely. Contact your healthcare provider or an emergency healthcare service immediately if someone in your family shows signs of delirium.
