Overview

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.

Symptoms

Schizophrenia involves a range of problems with thinking (cognition), behavior or emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function. 
Symptoms may include:

Delusions

These are false beliefs that are not based in reality. For example, you think that you're being harmed or harassed; certain gestures or comments are directed at you; you have exceptional ability or fame; another person is in love with you; or a major catastrophe is about to occur. Delusions occur in most people with schizophrenia.

Hallucinations

These usually involve seeing or hearing things that don't exist. Yet for the person with schizophrenia, they have the full force and impact of a normal experience. Hallucinations can be in any of the senses, but hearing voices is the most common hallucination.

Disorganized thinking (speech)

Disorganized thinking is inferred from disorganized speech. Effective communication can be impaired, and answers to questions may be partially or completely unrelated. Rarely, speech may include putting together meaningless words that can't be understood, sometimes known as word salad.

Extremely disorganized or abnormal motor behavior

This may show in a number of ways, from childlike silliness to unpredictable agitation. Behavior isn't focused on a goal, so it's hard to do tasks. Behavior can include resistance to instructions, inappropriate or bizarre posture, a complete lack of response, or useless and excessive movement.

Negative symptoms

This refers to reduced or lack of ability to function normally. For example, the person may neglect personal hygiene or appear to lack emotion (doesn't make eye contact, doesn't change facial expressions or speaks in a monotone). Also, the person may have lost interest in everyday activities, socially withdraw or lack the ability to experience pleasure.

Symptoms in Teenagers

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: 

· Withdrawal from friends and family 
· A drop in performance at school 
· Trouble sleeping 
· Irritability or depressed mood 
· Lack of motivation 

Compared with schizophrenia symptoms in adults, teens may be: 

· Less likely to have delusions 
· More likely to have visual hallucinations

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. 

Helping someone who may have schizophrenia

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

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.

Causes

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.

Risk Factors

Although the precise cause of schizophrenia isn't known, certain factors seem to increase the risk of developing or triggering schizophrenia, including: 

• Having a family history of schizophrenia 
• Increased immune system activation, such as from inflammation or autoimmune diseases 
• Older age of the father 
• Some pregnancy and birth complications, such as malnutrition or exposure to toxins or viruses that may impact brain development 
• Taking mind-altering (psychoactive or psychotropic) drugs during teen years and young adulthood

Prevention

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.
