Psychotic depression can feel frightening, confusing and deeply isolating. When severe depressive symptoms combine with hallucinations, delusions or a loss of connection with reality, everyday life can become overwhelming.

However, psychotic depression is treatable. With the right support, many people experience significant improvement in their symptoms and regain stability and clarity.

If you think you or someone close to you may be experiencing psychotic depression, understanding what is happening can be an important first step towards accessing specialist care.

If you or someone else is at immediate risk, call 999 or attend your nearest A&E department. You can also visit Priory’s crisis support page for urgent guidance.

What is psychotic depression?

Psychotic depression, sometimes referred to as severe depression with psychotic features, is a form of major depressive disorder that involves both:

  • Symptoms of severe depression
  • Psychotic experiences, such as hallucinations or delusional beliefs

Psychosis affects how someone interprets reality. In psychotic depression, these experiences often reflect themes of hopelessness, guilt, worthlessness or self-criticism that are already present in the depressive episode.

Because of this, psychotic depression can be particularly distressing and may significantly affect safety, functioning and emotional wellbeing. Early assessment and treatment are important.

Symptoms of psychotic depression

Psychotic depression symptoms and causes

Psychotic depression combines symptoms of severe depression with symptoms of psychosis. Experiences vary from person to person.

Psychotic symptoms

These may include:

  • Hallucinations – seeing, hearing, feeling or smelling things that are not present
  • Delusions – strongly held beliefs that are not based in reality
  • Paranoia – feeling watched, judged or unsafe without clear evidence
  • Disorganised or confused thinking

Psychotic experiences often reflect the tone of the depression. For example, someone may hear a voice criticising them or believe they have caused harm despite reassurance to the contrary.

Depressive symptoms

In addition to psychosis, symptoms of severe depression may include:

  • Persistent sadness or hopelessness
  • Anxiety or agitation
  • Irritability or anger over minor issues
  • Difficulty concentrating
  • Loss of interest in previously enjoyed activities
  • Sleep disturbance or insomnia
  • Changes in appetite
  • Ongoing fatigue or low energy
  • Feelings of guilt or worthlessness
  • Neglecting personal care

Psychotic depression may also involve thoughts of self-harm or suicide. This requires urgent medical attention.

Psychotic depression after childbirth

In some cases, new mothers may experience hallucinations or delusions related to their baby. This may form part of postnatal depression and requires urgent assessment. With prompt treatment, outcomes can be very positive.

What causes psychotic depression?

There is no single cause of psychotic depression. It usually develops due to a combination of biological, psychological and environmental factors.

These may include:

Genetics - A family history of severe depression or psychotic illness may increase vulnerability.

Hormonal changes -Hormonal shifts during pregnancy, after childbirth or during menopause may contribute.

Existing mental health difficulties - A history of depression, anxiety or other psychiatric conditions can increase risk.

Stressful life events - Bereavement, relationship difficulties, trauma or major life changes can trigger or worsen symptoms.

Childhood adversity - Early experiences of trauma, neglect or abuse may affect emotional regulation later in life.

Personality traits - People who are highly self-critical or prone to low self-esteem may be more vulnerable during periods of stress.

How psychotic depression is diagnosed

Diagnosis involves a thorough mental health assessment carried out by a GP, psychiatrist or psychologist.

This typically includes:

  • A detailed discussion of mood, sleep, daily functioning and emotional experiences
  • Questions about hallucinations, delusional beliefs or changes in perception
  • A review of medical and family history
    Consideration of recent life events or stressors

Because psychotic depression is a serious mental health condition, early diagnosis allows timely access to appropriate treatment.

Treatment for psychotic depression

Psychotic depression is treatable. Treatment is usually tailored to the severity of symptoms and the individual’s needs.

Inpatient treatment

Many people benefit from a short period of inpatient care, particularly if symptoms are severe or safety is a concern. Inpatient treatment provides:

  • 24-hour clinical support
  • A structured and therapeutic environment
  • Rapid access to psychiatric review
  • Medication monitoring
  • Psychological therapy

This setting can help stabilise symptoms in a safe and supportive way.

Outpatient and day care treatment

If symptoms are stable enough to be managed at home, outpatient or day care treatment offers regular therapy and psychiatric input while allowing someone to maintain aspects of their usual routine.

Online therapy

Online therapy can offer flexible access to psychological support, particularly during step-down care or where remote sessions are preferred.

Therapy for psychotic depression

Psychological therapy plays a central role in treatment.

Cognitive behavioural therapy (CBT)

CBT is commonly used and can help you:

  • Understand and challenge unhelpful thinking patterns
  • Explore delusional beliefs in a structured, supportive way
  • Develop coping strategies
  • Reduce the likelihood of relapse

Other therapeutic approaches

Depending on individual needs, treatment may also include:

  • Dialectical behaviour therapy (DBT)
  • Interpersonal therapy (IPT)
  • Mindfulness-based approaches
  • Compassion-focused therapy (CFT)
  • Family therapy, where appropriate

Therapy may be delivered individually, in groups or with family involvement.

Medication for psychotic depression

Medication is often an important part of treatment. This may include:

  • Antidepressants to address depressive symptoms
  • Antipsychotics to reduce hallucinations or delusions
  • Mood stabilisers or lithium, where clinically indicated

A consultant psychiatrist will carefully assess and monitor depression medication to support symptom stabilisation and longer-term management.

Supporting someone with psychotic depression

Supporting a loved one can feel overwhelming. You may find it helpful to:

Encourage open communication - Listen calmly and without judgement, allowing them to share at their own pace

Help them access professional support - Offer practical support such as attending appointments or contacting their GP or a private provider.

Learn about the condition - Understanding psychotic depression can help you respond with reassurance rather than fear.

Look after your own wellbeing - Supporting someone with severe mental illness can be emotionally demanding. Ensure you also access support when needed.
