Psychosis is a medical emergency, yet many people live with symptoms for months—or even years—before receiving treatment. This period is known as the duration of untreated psychosis (DUP).

Over the past several decades, researchers have found that the longer psychosis goes untreated, the more difficult recovery can become for many people. Early treatment does not guarantee a full recovery, but it is associated with better outcomes for many individuals.

What Is Psychosis?

Psychosis is a condition in which a person loses touch with reality.

They may experience:

• Hearing or seeing things that others cannot.
• Strong beliefs that are not based in reality (delusions).
• Confused or disorganised thinking.
• Difficulty concentrating or making sense of everyday situations.

These symptoms are frightening, not only for the person experiencing them but also for their family and friends.

Why Can Delaying Treatment Be Harmful?

Scientists are still learning exactly what happens in the brain during psychosis, but many studies suggest that prolonged, untreated psychosis may make recovery more difficult.

Several explanations have been proposed.

The Brain’s Chemical Messengers Become Disrupted

The brain uses chemical messengers called neurotransmitters to help nerve cells communicate.

One of these chemicals is dopamine, which plays an important role in motivation, reward, learning and perception.

During psychosis, dopamine signalling appears to become disrupted. If this imbalance continues for a long time without treatment, researchers believe the brain’s communication systems may become increasingly dysregulated, making symptoms harder to control.

Stress Takes a Toll on the Brain

Living with untreated psychosis is extremely stressful.

The body responds by releasing stress hormones such as cortisol.

While these hormones are helpful during short periods of stress, high levels over a long time may affect areas of the brain involved in memory, learning and emotional regulation.

This prolonged stress may add to the challenges people experience during recovery.

Brain Networks May Become Less Efficient

The brain works because billions of nerve cells communicate through complex networks.

Some researchers believe that ongoing psychosis may disrupt these connections, making it harder for different parts of the brain to work together efficiently.

This may contribute to problems with attention, memory, planning and decision-making that some people experience.

Does Psychosis Permanently Damage the Brain?

This is an area of ongoing research.

Some studies have found changes in brain structure and function in people who experience prolonged untreated psychosis. However, scientists do not yet fully understand how much of these changes are caused by the illness itself, how much may have been present beforehand, and how much can improve with treatment.

The encouraging news is that the brain has a remarkable ability to adapt.

Many people experience significant improvement with early treatment, medication when appropriate, psychological therapies, family support and rehabilitation.

Why Early Help Is So Important

The earlier psychosis is recognised and treated, the better the chance of reducing its impact.

Early intervention can:

• Reduce the severity of symptoms.
• Improve recovery.
• Help people return to work, education or family life sooner.
• Reduce distress for both the individual and their loved ones.
• Lower the risk of long-term disability.

There Is Hope

Experiencing psychosis does not mean someone cannot recover or live a fulfilling life.

Many people go on to work, study, have relationships and enjoy meaningful lives.

The most important message is this:

Psychosis should never be ignored or dismissed.

Like any serious medical condition, early recognition and treatment give people the best opportunity for recovery.

If you are worried that you or someone you know may be experiencing psychosis, seek professional medical advice as soon as possible. Early support can make a real difference.
