What Is Orientation?

Orientation is a term that encompasses a person's awareness of herself, those around her, her location and the date and time.

What Does It Mean When the Doctor Says that Someone Is Alert and Oriented Times Three?

You may hear a physician state, "She is alert and oriented times three." That means that she is awake and responsive, and oriented to person, place and time.

  • Oriented x 1 = awareness of person

    Sometimes a person is oriented only to himself. That means he knows who he is but can't recall anyone else- who they are or what their names are.

  • Oriented x 2 = knowledge of place

    Location may include general awareness of where the person is at, such as a hospital, room number at a nursing home, city and state.

  • Oriented x 3 = knowledge of time/date

    Time may include date, time of day and season.

How Does Alzheimer's Disease Affect Orientation?

Alzheimer's disease and other types of dementia can cause people to be disoriented about their surroundings and the setting. It's not uncommon for people with dementia to especially be disoriented about time. They may believe it's many years ago and that they are much younger than they are.

As Alzheimer's progresses, people may also become confused about where they are. For example, if asked the city and state in which they live, they may answer with the location of where they grew up rather than where they've lived for the last 30 years.

Finally, orientation to a person is affected by Alzheimer's disease in the very late stages where a person may not be able to remember his name or recognize himself in the mirror.

How Does Disorientation Impact the Person with Alzheimer's Disease?

If someone becomes disoriented to location, they may wander around and attempt to leave, both due to their confusion about place as well as time. For example, a person may believe that she must leave for work and then get lost on her way to a job that she retired from many years ago.

Thus, disorientation can present safety risks as well as distress and anxiety for people with dementia.

How Do Other Types of Dementia Affect Orientation?

Interestingly, not all types of dementia impact orientation to the same extent as Alzheimer's disease. A study was published in the Journal of Alzheimer's Disease about frontotemporal dementia which demonstrated that an impairment in both orientation and memory was found consistently in Alzheimer's, while people with frontotemporal dementia maintained their orientation but their memory was impaired.

How Is Orientation Assessed?

Orientation is assessed in both formal evaluations and informal conversations. Several mental status exams include questions about the date, the season of the year, and their location (hospital, home, city, county).

Orientation can also be assessed through informal conversation by asking the person a few questions.

How Is Orientation Affected by Delirium?

Orientation can also be affected by delirium, a sudden decline in someone's cognitive ability caused by a reversible condition such as a medication interaction or reaction or an infection.

If someone's orientation is suddenly poor, this is a sign that he may be experiencing delirium and warrants a medical exam and treatment.
