Orientation is a function of the mind involving awareness of three dimensions: time, place and person. Problems with orientation lead to disorientation, and can be due to various conditions, from delirium to intoxication. Typically, disorientation is first in time, then in place and finally in person.
The exact cerebral region involved in orientation is uncertain, but lesions of the brain stem and the cerebral hemispheres have been reported to cause disorientation, suggesting that they act together in maintaining awareness and its subfunction of orientation.
Causes of mental disorientation
Disorientation can occur in healthy young adults as well as in the elderly or ill person. While exercising, if a person becomes dehydrated as a result of over-exertion, he or she may become disorientated to the time or place. While exercising, the body may not be able to supply enough oxygen to the brain fast enough.
