The cause of schizophrenia is unknown but it is associated with problems in brain structure and chemistry. There may be some genetic role.
Schizophrenia does not develop because of one factor. You may have a gene that increases your chance of schizophrenia, but you may not develop the disease based on your environment. Environment means any outside factor like stress or infection.
Factors that may increase your chance of schizophrenia include:
Men typically develop symptoms in their late teens or early twenties. Schizophrenia in women tends to occur in their twenties or thirties. In rare cases, it is seen in childhood.
Symptoms often appear slowly. Early signs may include difficulty with relationships, school or work. The symptoms may become more disturbing and bizarre over time or occur in a matter of weeks or months.
Positive symptoms are behaviors that are not generally seen in healthy people. They may lose touch with reality with:
Negative symptoms are associated with breaks in normal emotions and behaviors, such as:
Cognitive symptoms are changes in memory and thinking, such as:
You, or a loved one or caregiver, will be asked about your symptoms and medical and mental health history. A physical exam will be done. A psychological exam may also be done.
It will take some time to confirm a schizophrenia diagnosis. Tests may be done to rule out other conditions or lifestyle habits such as drug use that can cause similar symptoms. Schizophrenia is diagnosed when 2 or more of the following symptoms occur and reduce ability of day to day life:
Schizophrenia is not curable, but symptoms can be reduced through treatment. Early, aggressive treatment can lead to better outcomes and may delay progression of schizophrenia to psychosis.
Hospitalization may be required during acute episodes. Symptoms are usually controlled with antipsychotic medications. Talk to your doctor about the best treatment plan for you. Options may include one or more of the following:
Antipsychotics work by blocking certain chemicals in the brain. This helps control the abnormal thinking that occurs in people with schizophrenia. Determining a drug plan can be a complicated process. Often medications or dosages need to be changed until the right balance is found. This can take months or even years. The right balance of medication will have the least amount of side effects possible with the greatest benefit.
It is important to continue taking the medication even if you are feeling better. Symptoms will return once the medication has been stopped. A long-acting injection instead of daily pills may be used if you have difficulty taking regular medication.
Antipsychotics also have side effects that may make it difficult to stick to a medication routine. Common side effects include:
Medications called atypical antipsychotics have fewer side effects and are better tolerated over long periods of time. However, these medications may cause significant weight gain, high blood sugar, and high cholesterol.
Schizophrenia is a lifelong condition. It can be confusing and frightening for the person with the disease and for family members. Individual and family therapy can address:
