Some causes of disorientation are alcohol or drug intoxication, brain tumors, head injuries, fever, and a fluid or electrolyte imbalance, claims MedlinePlus. Low blood sugar, seizures, low oxygen levels and hypothermia are also causes of disorientation.
Disorientation, also known as confusion, occurs when a person cannot think clearly. Disorientation causes an inability to recognize people, places, time and dates, according to MedicineNet.
Other signs of disorientation include slurring words or long pauses while speaking, abnormal speech and sudden emotional changes. Forgetting a task while performing it and lack of awareness of time and location are also symptoms of disorientation, claims Healthline.
