- a state of dull consciousness with a complex orientation in place, time, environment, but maintaining orientation in one's own personality.
Patients have abundant deceptions of perception (hallucinations) when they see objects that do not exist in reality, people, hear voices. Being absolutely confident in their existence, they cannot distinguish real events from unreal ones, and therefore their behavior is due to a delusional interpretation of the environment. Strong excitement is noted, there can be fear, horror, aggressive behavior depending on hallucinations. Patients in this regard can be a danger to themselves and others. Upon exiting delirium, the memory of the experience is preserved, while the events that actually took place may fall out of memory. The delirious state is characteristic of severe infections, poisoning.
