Disorganization is a symptom of schizophrenia. In the past, doctors considered “disorganized schizophrenia” to be a subtype of the condition, but this is no longer the case.
While this issue once defined a subtype of schizophrenia, mental health professionals no longer use any subtypes when diagnosing or classifying the condition.
This is because the qualities that defined these subtypes are not stable. As a result, the subtypes are not reliable or useful, when making a diagnosis, for example.
The fifth, and latest, edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published in 2013, defines schizophrenia as a single condition, which may or may not include disorganization.
The following are the key types of schizophrenia symptoms. We give examples and more details below.
- disorganized speech and thoughts
- disorganized or catatonic behavior
- negative symptoms, such as an inability to show emotion or perform routine tasks
A person with delusions believes things that are untrue, such as that someone is persecuting them or that they have extraordinary powers or gifts. Some people with schizophrenia hide to protect themselves from an imagined pursuer.
Someone having a hallucination sees, feels, tastes, or smells things that are not there. For example, a person may hear voices that seem real, even though they are not.
Having “disorganized speech and thoughts” refers to an inability to form coherent or logical thoughts, and this leads to disorganized speech.
During a conversation, a person with this symptom might leap from one topic to another. When the issue is severe, a person’s speech may be garbled and impossible for someone else to understand.
Disorganized or catatonic behavior can vary from being childlike and silly to aggressive and violent. This type of symptom can also involve excessive movements, unusual actions, freezing in place, or not responding to instructions or communication. There may also be unprovoked agitation or sexual behavior in public.
A person having “negative symptoms” of schizophrenia may be unable to carry out routine tasks, such as taking care of personal hygiene. They may withdraw from others and be unable to show emotion, and this may involve avoiding eye contact or speaking in a monotone.
Experts are not sure what causes schizophrenia. Research suggests that the issue lies in the function of the brain and that genetic and environmental factors may play a role.
The following factors appear to increase the risk of developing schizophrenia:
- the chemistry and structure of the brain
- the age of their parents when the person was born
- viral infection while in the womb
- maternal malnutrition
- severe stress during early life
Genetic factors may
In addition, an imbalance in the neurotransmitters dopamine, glutamate, and serotonin may affect how the brain of a person with schizophrenia reacts to sights, sounds, and other stimuli. This could explain why loud noises and bright lights can be so disturbing for people with the condition, and it may also underlie hallucinations. Problems with connections in the brain may also play a role.
Meanwhile, a range of factors related to pregnancy can increase the chances of having schizophrenia.
One such factor is age: The first child born to either younger or older parents may have a higher risk of developing schizophrenia than a person born to parents aged 25–29 years, according to some
Also, if a viral infection occurs during pregnancy, it may pass to the fetus and increase the risk of schizophrenia. It is unclear which viruses affect this risk, but they may include influenza, herpes, toxoplasmosis, and rubella.
A person’s experiences during early life may also contribute to their risk of schizophrenia.
Also, using recreational drugs during adolescence
If a person sees a doctor about symptoms of schizophrenia, the doctor will ask about:
- the symptoms and when they started
- personal and family medical histories
- lifestyle factors and recent events
They may run tests to rule out other causes of the symptoms, such as substance use or a brain injury.
The tests may include:
- a physical examination
- blood tests
- a brain scan
If the doctor believes that the person may have schizophrenia, they may perform a psychological evaluation or refer the person to a mental health professional.
For a diagnosis of schizophrenia, a person must experience
The symptoms are:
- disorganized speech
- disorganized behavior
- negative symptoms
Also, the symptoms must have disrupted the person’s work, interpersonal relationships, or self-care. They must also have lasted for at least 6 months.
If a person has had symptoms for 1 month or less, the doctor may make a diagnosis of brief psychotic disorder. If the symptoms have lasted 1–6 months, the diagnosis is schizophreniform disorder.
People with schizophrenia may need urgent care when their symptoms first appear. They then require ongoing treatment to prevent the symptoms from returning.
The best course of action will depend on the type and severity of the symptoms and the person’s overall health, age, and other factors.
A treatment plan
A doctor will prescribe antipsychotic drugs to adjust the balance of chemicals in the brain and prevent a reoccurrence of symptoms.
These drugs can have adverse effects, and it is important to let the person’s healthcare team know about any side effects. The doctor can adjust the dosage or recommend another medication.
Psychotherapy can help people:
- identify and adjust their feelings and ways of thinking
- manage their symptoms
- increase their ability to handle challenging situations
Social and vocational training
This can help a person live independently. It can be a crucial part of a recovery plan.
It might involve a therapist helping a person manage everyday tasks, such as:
- maintaining hygiene
- preparing meals
- communicating effectively
It can also involve help finding work, housing, and support groups.
When symptoms are severe, the person may need to spend time in a hospital. The aim is to reduce symptoms and provide a safe, restful environment, necessary nutrition, and help with hygiene.
The importance of following the treatment plan
People with schizophrenia often find it hard to follow their treatment plans. A
Friends, family, and healthcare professionals can provide essential support in this area.
People with schizophrenia may experience:
- problems with self-care, leading to low nutrition and
- substance abuse
- work and study problems
- obsessive-compulsive disorder, known as OCD
- housing and financial issues
- relationship problems
- suicidal thoughts and behavior
Treatment and support from family and friends, healthcare providers, and the community can help reduce the risk of these problems.
If you know someone at immediate risk of self-harm, suicide, or hurting another person:
- Ask the tough question: “Are you considering suicide?”
- Listen to the person without judgment.
- Call 911 or the local emergency number, or text TALK to 741741 to communicate with a trained crisis counselor.
- Stay with the person until professional help arrives.
- Try to remove any weapons, medications, or other potentially harmful objects.
If you or someone you know is having thoughts of suicide, a prevention hotline can help. The National Suicide Prevention Lifeline is available 24 hours per day at 800-273-8255. During a crisis, people who are hard of hearing can call 800-799-4889.
Schizophrenia is a serious mental health issue that can involve disorganized thinking, speech, and behavior. It can have a severe impact on a person’s life.
Medication, therapy, and other forms of support can reduce symptoms, prevent complications, and help the person live independently and foster relationships.
Receiving continual care from loved ones, a healthcare team, and support groups can help a person follow their treatment plan and maintain a good quality of life.
