What Causes Schizophrenia?

The cause of schizophrenia is not entirely understood but it is believed to be due to a combination of factors: 

  • Genetics
    • Schizophrenia can run in families 
  • Environment, combined with genetic predisposition
    • Living in poverty
    • Stressful surroundings
    • Exposure to viruses or nutritional problems prenatally
  • Brain structure and function
    • Differences in brain structure, function, and interactions among neurotransmitters in the brain may contribute to the development of schizophrenia

Certain triggers may cause schizophrenia to develop in people who are at risk, such as:

  • Stressful life events
    • Loss of a loved one  
    • Loss of a job or home 
    • Divorce 
    • Relationship breakup
    • Physical, sexual, or emotional abuse 
  • Drug abuse
    • Drug misuse doesn’t cause schizophrenia, but it increases the risk of developing the disease
    • Cannabis, cocaine, LSD, and amphetamines in particular may trigger symptoms in susceptible individuals 
    • Amphetamine or cocaine use can lead to psychosis and relapses 
    • Teenagers and young adults who use cannabis regularly are more likely to develop schizophrenia later in adulthood

How Is Schizophrenia Diagnosed?

There is no specific test for schizophrenia. Schizophrenia is usually diagnosed with an assessment by a mental health professional.

A diagnosis of schizophrenia may be made when a person has two or more of the following symptoms occurring persistently in the context of reduced functioning:

  • Delusions
  • Hallucinations
  • Disorganized speech
  • Disorganized or catatonic behavior
  • Negative symptoms

Tests may be performed in some cases to rule out other causes for the symptoms, such as brain tumors, other medical conditions, and other psychiatric diagnoses such as bipolar disorder.

What Is the Treatment for Schizophrenia?

Treatment for schizophrenia includes medications along with counseling and support.

Medications used to treat schizophrenia are called antipsychotics, which patients usually have to take for the rest of their lives. These medicines can often cause uncomfortable side effects which may cause patients to stop taking them. Never stop taking a prescribed medication without first talking to your doctor. Your doctor may be able to change the dose or switch medications to find one that works best for you while also minimizing side effects. It may take a number of tries with different medications to find the right one for you. 

Counseling and other support for schizophrenia includes: 

  • Cognitive behavioral therapy
  • Behavioral skills training
  • Supported employment
  • Cognitive remediation interventions to help address the negative and cognitive symptoms of schizophrenia
  • Family education and support programs
  • Coordinated specialty care (CSC), which is recovery-oriented treatment programs for people with first episode psychosis, an early stage of schizophrenia
  • Assertive Community Treatment (ACT) for individuals with schizophrenia who are at risk for repeated hospitalizations or homelessness

What Are Complications of Schizophrenia?

Complications of untreated schizophrenia may include:

  • Depression
  • Anxiety disorders 
  • Obsessive-compulsive disorder (OCD)
  • Suicide, attempted suicide, and thoughts of suicide
  • Alcohol and drug abuse
  • Financial problems 
  • Difficulty keeping a job or attending school
  • Homelessness
  • Social isolation
  • Health problems
  • Being victimized
