Orientation refers to an individual's awareness of time, place, and person. The document discusses orientation and how it is assessed through a series of questions covering four areas: time, place, person, and space. Disorientation, or the lack of proper orientation, is commonly seen in conditions like confusion states, amnestic syndromes, and dementias. Disorientation to time typically occurs before place and then person. The document provides details on assessing and interpreting orientation and disorientation in clinical psychiatric evaluations.
