Psychosis in Bipolar Disorder

Psychosis means losing touch with what is real: holding fixed false beliefs (delusions), hearing or seeing things others do not (hallucinations), or thinking in a way that becomes disorganized. In bipolar disorder it appears during severe mood episodes, most often mania but also depression, and a review in Current Psychiatry Reports estimates that more than half of people with bipolar disorder experience it at some point. Psychosis is a medical emergency first. This page explains what it looks like and what follow-up care involves once someone is stable.

Emergency care comes first

What psychosis looks like in bipolar disorder

The same review describes the forms psychosis can take during a manic episode:

• Grandiose delusions, the most common type: believing one has a special mission, hidden wealth, unique powers or a relationship with someone famous
• Hallucinations, usually voices
• Thought disorder: speech that jumps so fast or so loosely that it no longer holds together
• Catatonia: becoming very still and unresponsive, or showing odd, repetitive movement

Psychosis during an elevated episode makes that episode mania by definition; Merck notes that hypomania never includes psychotic features. So a person who has psychosis during a high is diagnosed with bipolar I disorder. For the full picture of the episode itself, see symptoms of a manic episode. Psychosis in severe depression tends to take a different, darker form, described below.

Mood-congruent and mood-incongruent features

NIMH notes that psychotic symptoms in bipolar disorder tend to match the person's extreme mood. Clinicians call that mood-congruent. In mania, the themes are usually power, importance and destiny. In depression, they are usually guilt, sin, illness, poverty or deserved punishment.

Mood-incongruent features do not fit the mood: for example, persecutory beliefs with no grandiose theme during mania, or the sense that thoughts are being inserted from outside. A German study that followed 182 people with bipolar I for an average of almost 17 years found that most individual episodes had no mood-incongruent symptoms, but most patients had them at some point. A large 2018 genetic study found that the polygenic risk for schizophrenia was highest in people with prominent mood-incongruent psychosis, lower with mood-congruent psychosis and lowest with no psychosis. These features do not change the diagnosis on their own, but they prompt a careful look at the alternatives below.

Bipolar disorder, schizoaffective disorder or schizophrenia?

NIMH warns that bipolar disorder with psychotic symptoms can be misdiagnosed as schizophrenia. The central question is timing. In bipolar disorder, psychosis comes and goes with the mood episodes. Merck explains that in schizoaffective disorder, psychotic features persist beyond the mood episodes; in schizophrenia, psychosis is the main, ongoing illness. A careful history, family history and how a person has responded to past treatment all help tell them apart. The comparison is covered in depth in bipolar disorder versus schizophrenia and schizoaffective disorder.

Other causes need ruling out too. Stimulants, cocaine, corticosteroids and withdrawal states can produce psychosis, and medical illness can as well. Psychosis that begins in the weeks after childbirth is its own emergency, closely linked to bipolar disorder; see postpartum psychosis.

Why the hospital usually comes before the clinic

Psychosis tends to arrive with the most severe phase of an episode. Insight is often limited: Merck describes how a lack of insight combined with high energy can become dangerous, and people may stop eating, drinking or sleeping. Merck notes that severe manic psychosis usually needs urgent treatment with a sedating second-generation antipsychotic, sometimes with a short-term benzodiazepine, which is care delivered in an emergency department or hospital.

NIMH adds that electroconvulsive therapy is considered when a rapid response is needed, for example with high suicide risk or catatonia. ECT is not offered at Willow & Stone; when it is indicated, a referral is made.

After stabilization: what outpatient follow-up covers

The weeks after discharge are a vulnerable time and a chance to build a plan that prevents the next episode. A good follow-up visit usually covers:

• The discharge summary and medication list. Bring them. Knowing what was started in hospital, and why, lets the outpatient prescriber continue and adjust safely.
• Continuing treatment. NIMH describes bipolar disorder as usually needing lifelong treatment. Stopping a mood stabilizer or antipsychotic suddenly raises the risk of relapse, so any change is planned with the prescriber. Antipsychotics for bipolar disorder and bipolar medications explained describe the options.
• Physical monitoring. NICE recommends checking weight, blood pressure, glucose or HbA1c and lipids before an antipsychotic is started and again around 12 weeks; labs are ordered as needed. See lab tests for bipolar disorder.
• Sleep and routine. NIMH advises regular times for sleeping, eating and exercise, and avoiding alcohol and drugs.
• Therapy. NIMH notes that family-focused therapy helps when started together with mood-stabilizing medication after an episode; see therapy for bipolar disorder.

A relapse plan, written while well

Psychosis rarely arrives without warning. Looking back, many families can name the first signs: a few nights of short sleep, new suspicion, unusual ideas, pulling away from people, or a sudden burst of plans. Writing these down together, while the person is well, turns hindsight into a plan.

1. List the personal early warning signs, in the person's own words.
2. Agree who will notice and how they will raise it.
3. Write down the prescriber's number, the nearest emergency room and 988.
4. Decide in advance what level of change means a same-day call and what means going to the ER.
5. Keep a mood and sleep chart so changes show up early.

Bipolar triggers and early warning signs has more ideas. Many people also feel embarrassed or frightened about what happened during the episode. Talking about it with a therapist or a trusted clinician is part of recovery, not a detour from it.

At Willow & Stone

Willow & Stone provides outpatient, scheduled care and is not an emergency service. Once a person is stable after emergency or hospital care, an integrative psychiatric evaluation can be the start of ongoing outpatient follow-up; see bipolar disorder treatment at Willow & Stone for how that works. If a higher level of care is needed, we help you find it. For the complete overview, read our bipolar disorder guide.
