This severe mental disorder can result in hallucinations, delusions, and extremely disordered thinking and behavior that interfere with daily living.
Schizophrenia is a serious mental disorder in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior that impairs daily functioning, and can be disabling.
People with schizophrenia require lifelong treatment. Early treatment may help get symptoms under control before serious complications develop and may help improve the long-term outlook.
Schizophrenia involves a range of problems with thinking (cognition), behavior and emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function. Symptoms may include:
Symptoms can vary in type and severity over time, with periods of worsening and remission of symptoms. Some symptoms may always be present.
In men, schizophrenia symptoms typically start in the early to mid-20s. In women, symptoms typically begin in the late 20s. It's uncommon for children to be diagnosed with schizophrenia and rare for those older than age 45.
Schizophrenia symptoms in teenagers are similar to those in adults, but the condition may be more difficult to recognize. This may be in part because some of the early symptoms of schizophrenia in teenagers are common for typical development during teen years, such as:
Also, recreational substance use, such as marijuana, methamphetamines or LSD, can sometimes cause similar signs and symptoms.
Compared with schizophrenia symptoms in adults, teens may be:
People with schizophrenia often lack awareness that their difficulties stem from a mental disorder that requires medical attention. So it often falls to family or friends to get them help.
If you think someone you know may have symptoms of schizophrenia, talk to him or her about your concerns. Although you can't force someone to seek professional help, you can offer encouragement and support and help your loved one find a qualified doctor or mental health professional.
If your loved one poses a danger to self or others or can't provide his or her own food, clothing, or shelter, you may need to call 911 or other emergency responders for help so that your loved one can be evaluated by a mental health professional.
In some cases, emergency hospitalization may be needed. Laws on involuntary commitment for mental health treatment vary by state. You can contact community mental health agencies or police departments in your area for details.
Suicidal thoughts and behavior are common among people with schizophrenia. If you have a loved one who is in danger of attempting suicide or has made a suicide attempt, make sure someone stays with that person. Call 911 or your local emergency number immediately. Or, if you think you can do so safely, take the person to the nearest hospital emergency room.
It's not known what causes schizophrenia, but researchers believe that a combination of genetics, brain chemistry and environment contributes to development of the disorder.
Problems with certain naturally occurring brain chemicals, including neurotransmitters called dopamine and glutamate, may contribute to schizophrenia. Neuroimaging studies show differences in the brain structure and central nervous system of people with schizophrenia. While researchers aren't certain about the significance of these changes, they indicate that schizophrenia is a brain disease.
Although the precise cause of schizophrenia isn't known, certain factors seem to increase the risk of developing or triggering schizophrenia, including:
Left untreated, schizophrenia can result in severe problems that affect every area of life. Complications that schizophrenia may cause or be associated with include:
There's no sure way to prevent schizophrenia, but sticking with the treatment plan can help prevent relapses or worsening of symptoms. In addition, researchers hope that learning more about risk factors for schizophrenia may lead to earlier diagnosis and treatment.
Diagnosis of schizophrenia involves ruling out other mental health disorders and determining that symptoms are not due to substance abuse, medication or a medical condition. Determining a diagnosis of schizophrenia may include:
Schizophrenia requires lifelong treatment, even when symptoms have subsided. Treatment with medications and psychosocial therapy can help manage the condition. In some cases, hospitalization may be needed.
A psychiatrist experienced in treating schizophrenia usually guides treatment. The treatment team also may include a psychologist, social worker, psychiatric nurse and possibly a case manager to coordinate care. The full-team approach may be available in clinics with expertise in schizophrenia treatment.
Medications are the cornerstone of schizophrenia treatment, and antipsychotic medications are the most commonly prescribed drugs. They're thought to control symptoms by affecting the brain neurotransmitter dopamine.
The goal of treatment with antipsychotic medications is to effectively manage signs and symptoms at the lowest possible dose. The psychiatrist may try different drugs, different doses or combinations over time to achieve the desired result. Other medications also may help, such as antidepressants or anti-anxiety drugs. It can take several weeks to notice an improvement in symptoms.
Because medications for schizophrenia can cause serious side effects, people with schizophrenia may be reluctant to take them. Willingness to cooperate with treatment may affect drug choice. For example, someone who is resistant to taking medication consistently may need to be given injections instead of taking a pill.
Ask your doctor about the benefits and side effects of any medication that's prescribed.
These newer, second-generation medications are generally preferred because they pose a lower risk of serious side effects than do first-generation antipsychotics. Second-generation antipsychotics include:
These first-generation antipsychotics have frequent and potentially significant neurological side effects, including the possibility of developing a movement disorder (tardive dyskinesia) that may or may not be reversible. First-generation antipsychotics include:
These antipsychotics are often cheaper than second-generation antipsychotics, especially the generic versions, which can be an important consideration when long-term treatment is necessary.
Some antipsychotics may be given as an intramuscular or subcutaneous injection. They are usually given every two to four weeks, depending on the medication. Ask your doctor about more information on injectable medications. This may be an option if someone has a preference for fewer pills and may help with adherence.
Common medications that are available as an injection include:
Once psychosis recedes, in addition to continuing on medication, psychological and social (psychosocial) interventions are important. These may include:
Most individuals with schizophrenia require some form of daily living support. Many communities have programs to help people with schizophrenia with jobs, housing, self-help groups and crisis situations. A case manager or someone on the treatment team can help find resources. With appropriate treatment, most people with schizophrenia can manage their illness.
During crisis periods or times of severe symptoms, hospitalization may be necessary to ensure safety, proper nutrition, adequate sleep and basic hygiene.
For adults with schizophrenia who do not respond to drug therapy, electroconvulsive therapy (ECT) may be considered. ECT may be helpful for someone who also has depression.
Coping with a mental disorder as serious as schizophrenia can be challenging, both for the person with the condition and for friends and family. Here are some ways to cope:
If you're seeking help for someone with schizophrenia, you may start by seeing his or her family doctor or health care professional. However, in some cases when you call to set up an appointment, you may be referred immediately to a psychiatrist.
To prepare for the appointment, make a list of:
Go with your loved one to the appointment. Getting the information firsthand will help you know what you're facing and what you need to do for your loved one.
For schizophrenia, some basic questions to ask the doctor include:
Don't hesitate to ask any other questions during your appointment.
The doctor is likely to ask you a number of questions. Anticipating some of these questions can help make the discussion productive. Questions may include:
The doctor or mental health professional will ask additional questions based on responses, symptoms and needs.
