What is disorientation?

Disorientation occurs when you are confused about the time, where you are or even who you are. It can be caused by a disease, illicit drugs, an infection or one of many other causes.

Signs that a person is disoriented may include:

  • an inability to focus their attention
  • being ‘slow’ and uncertain
  • mumbling and not making sense
  • not being able to recognise people they know
  • agitation and being upset
  • believing they can see things that aren't really there

A person with disorientation might also experience:

In some people, such as those with dementia, these symptoms might develop slowly. But a person who suddenly becomes confused and disoriented should see a doctor as soon as possible — whether they’re older or young. It could be a sign that they’re unwell.

What causes disorientation?

A common cause of disorientation is dementia, a condition that affects a person’s thinking, behaviour and their ability to perform everyday tasks. People with dementia are more likely to develop delirium when there is a sudden disturbance in their state of mind. This is often caused by an infection or medicines.

Another common cause of disorientation is drugs, especially alcohol or marijuana. It is also a side effect of some medicines.

There are many other causes of disorientation. Some of the more common ones include:

Some less-common causes of disorientation include:

How is disorientation treated?

Treatment will depend on the cause of the disorientation. It will often disappear once the underlying cause is treated.

If you are caring for a person with dementia, you can help them by keeping familiar things around them in the house. Arrange furniture and objects so they can find their way around.

People with dementia can suddenly become disoriented, even in previously familiar surroundings. If the person goes out, make sure they carry identification — including their name, address and an emergency contact number.

For more information on disorientation and dementia, visit the Dementia Australia website or call the National Dementia Helpline on 1800 100 500.

Can you prevent disorientation?

You should follow your doctor’s instructions if you are taking medicines to treat the cause of your disorientation.

If the cause is something that can’t be easily treated, talk to your doctor about dealing with disorientation in the future. Let your family know what to do if it happens again

When to seek help for disorientation

If a person suddenly becomes disoriented, call triple zero (000) and ask for an ambulance. Stay with them to keep them calm until help arrives.

When someone experiences symptoms of disorientation, it's important to see a doctor as soon as you are able.

It's important to identify what is causing the disorientation so that the right treatment can be started as soon as possible.
