Schizophreniform disorder

Schizophreniform disorder is a mental health condition that causes symptoms similar to schizophrenia—including hallucinations, delusions, and disorganized thinking—but with a critical difference: these symptoms last between one and six months, not a lifetime.

What is schizophreniform disorder?

Schizophreniform disorder is a short-term mental health condition that causes psychosis, which means losing touch with reality^[1]. When someone has this disorder, they experience symptoms like seeing or hearing things that aren’t there, holding false beliefs that seem very real to them, speaking in ways that don’t make sense to others, and behaving in unusual ways^[1].

The key difference between schizophreniform disorder and schizophrenia is how long the symptoms last. With schizophreniform disorder, symptoms must be present for at least one month but less than six months^[2]. If symptoms continue beyond six months, doctors will change the diagnosis to schizophrenia, which is a lifelong condition^[1].

Another important difference is that people with schizophreniform disorder may or may not experience problems with daily functioning in school, work, or relationships. In contrast, people with schizophrenia typically do have such difficulties^[2].

Schizophreniform disorder is much less common than schizophrenia. About one person in 1,000 develops this condition during their lifetime^[3]. The disorder affects men and women equally, though it often appears earlier in men—between ages 18 and 24—while in women it typically appears between ages 24 and 35^[3].

Symptoms and warning signs

The symptoms of schizophreniform disorder are identical to those of schizophrenia. The main symptoms include^[1]:

• Delusions: These are strongly held false beliefs that aren’t based on reality. A person refuses to change their mind even when shown evidence that proves the belief is wrong. For example, someone might believe they are being watched or followed when this isn’t happening.
• Hallucinations: These are false perceptions involving the senses—seeing, hearing, smelling, tasting, or feeling things that aren’t really there. Hearing voices is one of the most common types of hallucinations.
• Disorganized speech: The way a person talks becomes confusing to others. They might use made-up words, jump quickly from one topic to another, or say sentences that are hard to understand.
• Disorganized or unusual movements: A person might move in ways that seem strange to others, like pacing in circles for no clear reason, or they might barely move at all, a condition called catatonia.

In addition to these main symptoms, schizophreniform disorder includes what doctors call “negative symptoms.” These refer to a reduction or loss of normal abilities^[1]:

• Limited emotional expression
• Lack of energy or motivation
• Poor hygiene and grooming habits
• Loss of interest or pleasure in life
• Withdrawing from family, friends, and social activities

If you or someone you know develops these symptoms, it’s important to see a healthcare provider or mental health professional right away^[1].

What causes this condition?

Researchers don’t know the exact cause of schizophreniform disorder^[3]. Like other mental health conditions involving psychosis, it’s likely that a mix of factors work together to trigger the illness^[2].

Several factors may increase a person’s risk of developing schizophreniform disorder^[3][5]:

• Genetics: The tendency to develop schizophrenia and schizophreniform disorder may run in families. Having a parent or blood relative with schizophrenia can increase your chance of developing a similar condition by 10%^[5]. The condition is also more likely to occur in people with family members who have bipolar disorder^[2].
• Brain structure and function: People with schizophreniform disorder may have disturbances in brain circuits that control thinking and perception^[3]. Changes to the brain’s chemical structure may also play a role^[5].
• Environment: Very stressful events or poor relationships may trigger schizophreniform disorder in people who have inherited a tendency to develop the illness^[3]. Trauma—especially physical trauma, abuse, or experiencing war—can also increase risk^[5].

Scientists have proposed a stress-vulnerability model for psychotic disorders. This means some people have an underlying genetic vulnerability to the disorder that can be triggered by certain environmental factors^[2].

How is it diagnosed?

Diagnosing schizophreniform disorder requires careful evaluation by a mental health professional. If someone has symptoms, a doctor will first use various tests—such as brain imaging scans or blood tests—to rule out physical problems that could be causing the symptoms^[3].

If no physical cause is found, the person may be referred to a psychiatrist or psychologist. These mental health professionals use specially designed interviews and assessment tools to determine if someone has a psychotic disorder^[3].

To diagnose schizophreniform disorder, at least two of the following symptoms must be present for a significant portion of time during a one-month period, and at least one must be delusions, hallucinations, or disorganized speech^[6]:

1. Delusions
2. Hallucinations
3. Disorganized speech
4. Grossly disorganized or catatonic behavior
5. Negative symptoms

The total duration of illness must be at least one month but less than six months^[6]. If symptoms have lasted at least one month, doctors may give a “provisional” diagnosis of schizophreniform disorder while waiting to see if the person recovers. If symptoms go away within six months, the provisional label is removed. However, if symptoms continue for six months or more, the diagnosis must be changed^[2].

Doctors must also rule out other conditions that can cause similar symptoms, including schizoaffective disorder, depression with psychotic features, bipolar disorder with psychotic features, brief psychotic disorder, and symptoms caused by substance use or other medical conditions^[6].

Treatment options

While there is no cure for schizophreniform disorder, it can be managed with the right support^[5]. Treatment typically includes a combination of medication and therapy.

Medication

Antipsychotic drugs are the main medications used to treat schizophreniform disorder^[3]. These medicines help control symptoms like delusions, hallucinations, and disorganized thinking^[3]. The treatment approach for schizophreniform disorder is similar to that used for schizophrenia^[6].

Commonly used antipsychotic medications include risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole, paliperidone, asenapine, iloperidone, and lurasidone^[6]. Some of these medications are available in injectable forms, which may cause fewer side effects related to movement^[6]. In addition to antipsychotics, mood stabilizers and anti-anxiety medications can also be helpful^[5].

People with severe symptoms or those at risk of hurting themselves or others may need to be hospitalized to get their condition under control^[3].

Psychotherapy

Therapy is often considered a cornerstone of treatment for schizophreniform disorder^[5]. Psychotherapy (a type of counseling) helps people recognize and learn about their illness and its treatment, set goals, and manage everyday problems related to the condition^[3]. It can also help people handle the feelings of distress linked to their symptoms^[3].

Cognitive behavioral therapy can help people learn the coping skills they need to handle their disorder^[5]. Virtually all types of psychotherapy used to treat schizophrenia may be helpful for people with schizophreniform disorder^[11].

Group psychotherapy may also be useful, though people with schizophreniform disorder who are concerned about their future may become frightened in groups where they are mixed with people who have chronic schizophrenia^[11].

Family and social support

Family therapy can help families understand the condition and deal more effectively with a loved one who has schizophreniform disorder^[3][5]. Treatment frequently involves working with family members and significant others^[11].

Social and educational approaches designed to reduce the social and emotional impact of the illness can be very helpful^[2]. A supportive environment with minimal stimulation is most helpful as improvement progresses^[11].

Education

Learning more about schizophrenia and schizophreniform disorder can help people be aware of things to look for and find new strategies for living with the disorder^[5].

What to expect

The outlook for people with schizophreniform disorder varies. About one-third (33%) of people who receive a diagnosis of schizophreniform disorder will no longer have symptoms after six months^[1]. This means their symptoms resolve completely, and they don’t go on to develop schizophrenia^[5].

However, most of the remaining two-thirds (66%) of people will eventually receive a diagnosis of schizophrenia or schizoaffective disorder because their symptoms last longer than six months^[1][2]. Approximately 60% of people who present with schizophreniform disorder will eventually be diagnosed with schizophrenia and will likely need lifelong care^[15].

The prognosis depends on the nature, severity, and duration of the symptoms^[2]. Because of this variable course, treatment strategies must remain flexible to allow for the transition to longer-term treatments for those who progress to schizophrenia^[11].

Getting treatment early is important. Early treatment often helps control symptoms before serious complications arise, making the long-term outlook better^[1]. If someone you care about is showing signs of psychosis, don’t hesitate to seek professional help^[15].

Possible complications

The symptoms of schizophreniform disorder can significantly impact daily life. People may struggle with school or work, relationships, and self-care. This may lead to job loss and problems in relationships^[1].

People with psychotic disorders, including schizophreniform disorder, are at an increased risk of substance use and substance use disorder^[1]. Some people may be more likely to use alcohol or other substances to help cope with their symptoms, a practice sometimes called “self-medication.” If this happens, it’s important to reach out to a healthcare provider or mental health professional as soon as possible^[1].

People who experience psychosis are also at an increased risk of thinking about suicide or death by suicide^[1]. If someone has suicidal thoughts or behavior, they should see a healthcare provider immediately. In the United States, calling 988 connects people to the Suicide and Crisis Lifeline, where someone is available to help 24 hours a day, 7 days a week^[1].
