Bipolar disorder and schizophrenia overlap in some ways. For instance, both can lead to psychosis, a state of mind causing a detachment from reality. Although they have some similarities, they’re very different in other ways.
“Understanding the differences between bipolar disorder and schizophrenia is crucial for effective treatment,” says Harold Hong, MD, a psychiatrist and the medical director of New Waters Recovery, a mental health and substance abuse treatment facility in Raleigh, North Carolina. “A proper diagnosis ensures that individuals receive the most appropriate interventions, as treatment approaches differ significantly.”
Here’s what to know about the symptoms of bipolar disorder vs. schizophrenia, how they differ, and treatment options for each.
Bipolar Symptoms vs. Schizophrenia Symptoms
Bipolar Disorder Symptoms
Bipolar disorder is a mood disorder involving periods of intense emotional states that interfere with an individual’s energy, mood, and functioning. These periods, known as mood episodes, last days to weeks at a time. There are three types of mood episodes: [1][2]
- Manic Episodes Periods of at least a week when a person is unusually euphoric, irritable, or has more energy than usual. “Mania is severely impairing,” says Karla Molinero, MD, the medical director for Newport Healthcare, a national network of evidence-based healing centers for teens and young adults with primary mental health disorders. “Those in mania typically go to the hospital for inpatient psychiatric care as they cannot function in the community.”
- Hypomanic Episodes These are less-severe symptoms of mania that last at least four days and don’t interfere with functioning in the same way mania does.
- Depressive Episodes These are periods of at least two weeks when a person has extreme sadness and loss of interest or pleasure in activities they usually enjoy.
Symptoms of manic episodes and hypomanic episodes (to a lesser degree) may include: [1][2]
- High spirits or elation
- More energy than usual
- Extreme irritability
- Racing thoughts
- A decreased need for sleep
- Unusual feelings of importance, power, or talent
- Hypersexuality, or difficulty controlling sexual impulses or behaviors
- Reckless or dangerous behaviors, such as risky sex
- In severe cases, psychosis (a detachment from reality that may involve hallucinations and delusions)
Symptoms of depression may include:[1][2]
- Sadness or anxiety
- Lack of interest or pleasure in activities you usually enjoy
- Trouble sleeping or sleeping too much
- Talking very slowly or having trouble finding anything to say
- Slowed movement
- Forgetfulness
- Difficulty concentrating or making decisions
- Feelings of worthlessness or hopelessness
- In severe cases, psychosis (a detachment from reality that may involve hallucinations and delusions)
- Thoughts of self-harm or suicide
There are three types of bipolar disorder:[1][2]
- Bipolar 1 Disorder People with bipolar 1 experience at least one manic episode. They usually also have periods of neutral mood. In some cases, they may also have hypomanic episodes or depressive episodes.
- Bipolar 2 Disorder People with bipolar 2 have at least one depressive episode and one hypomanic episode. Many people with bipolar 2 are able to function as usual between mood episodes.
- Cyclothymic Disorder People with cyclothymic disorder have a milder version of bipolar disorder involving frequent mood swings (shifts in mood) between hypomanic and depressive symptoms that are less severe than bipolar 1 or 2 disorder.
Some people may have bipolar symptoms that don’t fit into any of the categories above. This is known as other specified and unspecified bipolar and related disorders.
Schizophrenia Symptoms
Schizophrenia is a serious mental health condition that changes the way you act, think, feel, and understand your surroundings. Schizophrenia causes several kinds of symptoms:[3][4]
- Positive symptoms (also known as psychotic symptoms): These include symptoms of psychosis like hallucinations and delusions
- Negative symptoms: These are the absence of typical ways that an individual usually interacts with their surroundings. They can include talking in a monotonous or flattened tone of voice, flattened emotional expression, speaking very little even when forced to interact, a lack of interest in social interactions and day-to-day activities, and intense fatigue.
- Disorganized symptoms: These include disorganized thinking, speech, and movements. People with schizophrenia may struggle to organize their thoughts when speaking or may speak in ways that don’t make sense to others. They may also move in odd ways, such as spinning in circles for no obvious reason.
- Cognitive symptoms: These symptoms may include difficulty paying attention, trouble with decision-making, memory issues, and problems with processing information shortly after learning it.
How Bipolar Disorder and Schizophrenia Overlap
Bipolar disorder and schizophrenia have some things in common. As mentioned, they both can involve episodes of psychosis, including hallucinations and delusions, says Dr. Hong. They also typically begin during adolescence or early adulthood, says Sogand Ghassemi, MD, a child, adolescent, and adult Psychiatrist for Newport Healthcare’s PrairieCare psychiatric program in Minnesota.
The main difference between them is whether mood episodes are present and how often certain symptoms like psychosis appear. “In bipolar disorder, mood cycling (mania and depression) defines the clinical course, with psychotic symptoms typically appearing only during extreme mood states,” says Dr. Ghassemi. “In contrast, schizophrenia’s primary features are persistent psychotic symptoms, often without significant mood alterations.”
What Are the Treatment Options for Bipolar Disorder vs. Schizophrenia?
“Today, a blend of pharmacologic and non-pharmacologic therapies offers effective symptom management, improved functionality, and better quality of life for individuals with psychotic and mood disorders,” says Ghassemi.
Treatment options for schizophrenia can include:[4][5]
- Medications, such as antipsychotic drugs, mood stabilizers, antidepressants, or anti-anxiety drugs
- Psychotherapy (talk therapy with a mental health professional)
- Hospitalization, especially if the person is having symptoms of psychosis or suicidal or homicidal thoughts
- Electroconvulsive therapy, a brain stimulation procedure your provider may recommend if other treatments don’t provide enough symptom relief for you
The treatments for bipolar disorder may include:[1][2]
- Medication, such as mood stabilizers, antipsychotics, or in some cases, antidepressants
- Psychotherapy (talk therapy with a mental health professional)
- Hospitalization, especially if the person is having symptoms of mania, psychosis, or suicidal thoughts
- Electroconvulsive therapy, a brain stimulation procedure your provider may recommend if other treatments aren’t enough on their own to manage your symptoms
- Repetitive transcranial magnetic stimulation (rTMS), another form of brain stimulation your provider may suggest if other treatments aren’t helping enough
- Light therapy, which can help treat seasonal affective disorder (SAD), depression that happens or worsens during certain seasons but lifts in others. Some people with bipolar disorder who have depressive episodes may develop SAD.
“Both bipolar disorder and schizophrenia can be challenging, but effective treatments are available,” says Hong. “Many individuals manage their conditions successfully and lead fulfilling lives. With the proper support, recovery is possible.”
When to Get Help
If you or a loved one is having symptoms of mania or psychosis, seek medical help right away. As mentioned, individuals with schizophrenia or bipolar disorder who are having severe symptoms may need to be hospitalized until their symptoms are stable. Then your hospital team can refer you or a loved one for further treatment if needed.
People with schizophrenia or bipolar disorder have a higher risk of suicide than those without these conditions.[6][7] If you or a loved one is experiencing suicidal thoughts or behaviors, call 911 for emergency medical help or 988 to reach the Suicide & Crisis Lifeline to be connected with a trained crisis counselor. Signs and symptoms of suicidal thoughts or behaviors may include:[8]
- Talking about death or wanting to die
- Feeling shame, guilt, or like a burden to others
- Physical or emotional pain that feels like it’s too much to manage
- Feelings of hopelessness or emptiness
- Intense sadness, rage, anxiety, agitation, or mood swings
- Changes in sleeping or eating patterns
- Increased alcohol or drug use
- Taking risks, such as driving too fast
- Social withdrawal or saying goodbye to loved ones with no other logical reason for doing so
- Searching ways to die or creating a plan
The Takeaway
Bipolar disorder and schizophrenia are both serious mental health conditions that impact how individuals think and feel.
While they overlap in some ways, such as the risk for psychosis, their hallmark symptoms differ. Bipolar disorder involves extreme mood shifts between mania and depression, while schizophrenia primarily features persistent psychotic episodes.
Early intervention and lifelong treatment are key for managing symptoms and improving quality of life among people with either condition.
