Can you have bipolar disorder without ever having psychosis?

Yes. In a 2022 meta-analysis, 63% of people with bipolar I disorder had psychotic symptoms in their lifetime, so more than a third did not. In bipolar II disorder the lifetime rate was 22%. Psychosis is not required for either diagnosis.

Can hypomania include hallucinations?

No, not by definition. The diagnostic criteria do not allow psychotic symptoms in a hypomanic episode. If hallucinations or delusions occur with an elevated mood, clinicians class the episode as mania, and the diagnosis is bipolar I disorder.

Does bipolar psychosis go away?

It usually does. In bipolar disorder, psychotic symptoms occur during mood episodes and are absent between them. Treatment of the manic or depressive episode treats the psychosis. Psychosis that continues for two weeks or more without mood symptoms points to a different diagnosis.

Are delusions or hallucinations more common in bipolar disorder?

Delusions are more common. In a study of 1,342 people with bipolar I disorder, 68.9% had delusions in their lifetime and 42.6% had hallucinations. Many people have both.

Does psychosis mean my bipolar diagnosis is wrong and I have schizophrenia?

No. Psychosis during a manic or depressive episode fits bipolar disorder with psychotic features. Schizophrenia and schizoaffective disorder involve psychosis that continues when mood symptoms are not prominent. A clinician needs the full history over time to tell them apart.

Can Bipolar Disorder Cause Hallucinations or Delusions?

The short answer: Yes. Bipolar disorder can cause hallucinations and delusions, and it happens often. A 2022 meta-analysis put the lifetime rate of psychotic symptoms at 63% in bipolar I disorder and 22% in bipolar II disorder. These symptoms appear during mood episodes, mostly mania, and they usually fade when the episode is treated.

How common is psychosis in bipolar disorder?

Psychosis means some loss of contact with reality. The National Institute of Mental Health (NIMH) describes two main symptoms. Delusions are false beliefs, such as a belief that other people want to hurt you. Hallucinations are seeing or hearing things that other people do not, such as voices.

NIMH states that some people with bipolar disorder have these symptoms. Research gives the numbers. A 2022 systematic review and meta-analysis in Psychological Medicine pooled 54 studies and 23,461 adults with bipolar disorder. It defined psychotic symptoms as delusions or hallucinations. The main results:

Bipolar I disorder, lifetime: 63% had psychotic symptoms at some point.
Bipolar I disorder, hospital inpatients: 71%.
Bipolar II disorder, lifetime: 22%, from only seven small studies.

Delusions are more common than hallucinations. In a Dutch study of 1,342 people with bipolar I disorder, 73.8% had a lifetime history of psychotic symptoms. Delusions were present in 68.9% of patients and hallucinations in 42.6%. The gap between the two bipolar types is one of the main points in our guide to bipolar I versus bipolar II.

Does psychosis happen in mania or in depression?

It happens in both, but it is much more common in mania. The same meta-analysis measured how many people had psychotic symptoms during a current episode. The rate was 57% in manic episodes and 13% in depressive episodes. The authors said there were too few studies of mixed episodes to give a number.

Hypomania is different. The meta-analysis authors note that psychotic symptoms are, by definition, incompatible with hypomania. Under the DSM-5 rules, an elevated mood episode with psychotic symptoms is classed as mania. That makes the diagnosis bipolar I disorder, even if the other symptoms look mild. Read more about that line in hypomania versus feeling good.

This rule also explains the bipolar II number. The authors point out that psychotic symptoms in bipolar II disorder must occur during depressive episodes. If a low mood is the larger part of your illness, depression.md covers depressive symptoms and treatment in more detail.

What do hallucinations and delusions look like in bipolar disorder?

Clinicians sort psychotic symptoms into two groups, based on how well the content fits the mood.

Mood-congruent features fit the mood. In mania, a person may believe they have special powers, great wealth, or a mission. In depression, the beliefs turn to guilt, ruin, illness, or punishment that the person thinks they deserve.
Mood-incongruent features do not fit the mood. Examples are a belief that someone controls your thoughts, or a fear of persecution that has no link to how you feel.

Both groups occur in bipolar disorder. A Swiss study of 162 treated patients with bipolar I disorder found that 59.3% had experienced psychotic features in their lifetime. Among those patients, 44.8% had mood-incongruent features at least once.

The same study linked psychotic features to a harder course. Patients with psychotic features were less likely to be at work and used inpatient care more often. Those with mood-incongruent features were more likely to report hallucinations and suicide attempts. This is one study of one clinic population, so the result does not predict the course for one person.

Psychotic symptoms seldom arrive alone. They usually come with the other signs of mania, such as very little sleep, fast speech, and risky decisions.

How is bipolar psychosis different from schizophrenia or schizoaffective disorder?

The difference is timing. The symptoms themselves can look the same, so one episode does not settle the diagnosis. Clinicians look at when psychosis occurs across the whole illness.

A 2013 paper in Schizophrenia Research on schizoaffective disorder in the DSM-5 sets out the rules:

Bipolar disorder with psychotic features: psychotic symptoms occur only during a mood episode. Outside of episodes, they are absent.
Schizoaffective disorder or schizophrenia: there is at least a two-week period of psychosis without prominent mood symptoms.
Schizoaffective disorder specifically: full mood episodes must also be present for the majority of the illness since psychosis began.

The authors wrote that the older schizoaffective diagnosis had poor reliability and low stability. A diagnosis can change as clinicians see more of the course. An accurate history from the person and from family helps a great deal. Drugs, alcohol, some medicines, and other medical conditions can also cause psychosis, so a clinician will check for those.

How is psychosis in bipolar disorder treated?

Treatment targets the mood episode. When the episode ends, the psychotic symptoms usually end with it. Several drugs carry an FDA label for bipolar mania. Three examples from current labels:

Olanzapine: the Zyprexa label lists acute treatment of manic or mixed episodes of bipolar I disorder, and maintenance treatment. The trials included patients with or without psychotic features.
Quetiapine: the Seroquel label lists manic episodes of bipolar I disorder and depressive episodes of bipolar disorder. Its mania trials also included patients with or without psychotic features.
Lithium: the lithium carbonate label lists acute manic and mixed episodes of bipolar I disorder, and maintenance treatment, in patients 7 years and older.

These labels describe treatment of the episode. They do not list bipolar psychosis as a separate indication. Other antipsychotics also have a mania indication, and a prescriber chooses based on your history and side effects.

The UK guideline NICE CG185 takes a similar approach. For a person with mania who is not taking an antipsychotic or mood stabilizer, it recommends haloperidol, olanzapine, quetiapine, or risperidone. If a second antipsychotic is not effective enough, it says to consider adding lithium. It also says to consider stopping an antidepressant if mania develops.

Antipsychotics need monitoring. NICE calls for weight, pulse, blood pressure, blood glucose, and lipid checks before and during treatment. Do not stop a medicine without your prescriber, because NICE warns that stopping fast can raise the risk of relapse.

When is bipolar psychosis an emergency?

Treat new hallucinations or delusions as urgent. Contact the prescriber or care team the same day. Psychosis during a mood episode is a sign of a severe episode, and some people need hospital care.

NIMH notes that a person in a psychotic episode may behave in unpredictable ways and may harm themselves or others. It also states that the risk of violence and suicide decreases with treatment. Get help immediately in these cases:

The person talks about suicide or about harming someone.
Voices tell the person to hurt themselves or others.
The person cannot eat, drink, sleep, or stay safe.

The bottom line

Hallucinations and delusions are a common part of bipolar disorder. About 63% of people with bipolar I disorder and 22% of people with bipolar II disorder have them at some point. They occur during mood episodes, most often mania, and psychotic symptoms rule out hypomania by definition. Psychosis that continues without mood symptoms points to schizoaffective disorder or schizophrenia. Treatment of the mood episode is the treatment for the psychosis, and new symptoms need same-day medical contact.
