Schizophrenia

Schizophrenia is a complex, chronic brain disorder that affects less than one percent of the U.S. population. When schizophrenia is active, symptoms can include delusions, hallucinations, disorganized speech, trouble with thinking, and lack of motivation. However, with treatment, most symptoms of schizophrenia will greatly improve, and the likelihood of a recurrence can be diminished.

While there is no cure for schizophrenia, research is leading to innovative and safer treatments. Experts are also unraveling the causes of the disease by studying genetics, conducting behavioral research, and using advanced imaging to look at the brain's structure and function. These approaches hold the promise of new, more effective therapies.

The complexity of schizophrenia may help explain why there are misconceptions about the disease. Schizophrenia does not mean split personality or multiple personality disorder. Most people with schizophrenia are not any more dangerous or violent than people in the general population. While limited mental health resources in the community may lead to homelessness and frequent hospitalizations, it is a misconception that people with schizophrenia end up homeless or living in hospitals.

Schizophrenia involves a range of problems with thinking (cognition), behavior, and emotions. Symptoms are typically divided into three categories:

Cognitive Symptoms

• Poor executive functioning: Inability to understand information and use it to make decisions
• Trouble focusing: Difficulty paying attention
• Working memory problems: Trouble using information immediately after learning it
• Difficulty with "processing speed"
• Problems with learning and applying new information

Early Warning Signs

The prodromal phase may include:

• Social withdrawal and isolation
• Decline in academic or work performance
• Unusual thoughts or perceptions
• Difficulty concentrating
• Deterioration in personal hygiene
• Flat affect (lack of emotion)
• Inappropriate emotional responses
• Suspiciousness of others

While the DSM-5 no longer uses subtypes, understanding these historical categories can help describe symptom patterns:

Historical Subtypes

• Paranoid: Prominent delusions or hallucinations, relatively intact cognitive functioning
• Disorganized: Disorganized speech and behavior, flat or inappropriate affect
• Catatonic: Disturbances in movement and behavior
• Undifferentiated: Meeting general criteria but not fitting other subtypes
• Residual: History of schizophrenia but current absence of prominent symptoms

Related Psychotic Disorders

• Schizoaffective Disorder: Schizophrenia symptoms with major mood episodes
• Schizophreniform Disorder: Schizophrenia symptoms lasting 1-6 months
• Brief Psychotic Disorder: Sudden onset lasting less than 1 month
• Delusional Disorder: Delusions without other schizophrenia symptoms
• Substance-Induced Psychotic Disorder: Due to drugs or medications

The exact causes of schizophrenia are unknown, but research suggests a combination of genetic, brain chemistry, and environmental factors contributes to development of the disorder.

Genetic Factors

• Having a family history increases risk significantly
• If one parent has schizophrenia: 13% chance
• If both parents: 40% chance
• Identical twin: 45-50% chance
• Multiple genes involved, not a single "schizophrenia gene"

Brain Structure and Chemistry

• Neurotransmitter imbalances: Dopamine, glutamate, GABA
• Brain structure differences: Enlarged ventricles, reduced gray matter
• Connectivity issues: Problems with brain networks
• Developmental abnormalities: Issues during brain development

Environmental Factors

• Prenatal exposure: Infections, malnutrition, stress
• Birth complications: Oxygen deprivation, low birth weight
• Psychosocial factors: Childhood trauma, stress
• Drug use: Cannabis, especially in adolescence
• Urban environment: Higher rates in cities
• Migration: Increased risk in immigrants

The Stress-Vulnerability Model

This model suggests that people inherit different levels of vulnerability to schizophrenia, and environmental stressors can trigger the disorder in vulnerable individuals.

Diagnosing schizophrenia involves ruling out other mental health disorders and determining that symptoms are not due to substance abuse, medication, or a medical condition. Diagnosis may include:

Diagnostic Process

• Psychiatric evaluation: Assessment of symptoms, thoughts, and behavior
• Medical history: Including family psychiatric history
• Physical exam: To rule out other problems
• Tests and screenings: May include MRI, CT scan, blood tests
• Substance screening: To rule out drug-induced psychosis
• DSM-5 criteria: Must meet specific diagnostic criteria

DSM-5 Diagnostic Criteria

Two or more of the following for at least 1 month:

1. Delusions
2. Hallucinations
3. Disorganized speech
4. Grossly disorganized or catatonic behavior
5. Negative symptoms

Plus:

• Significant functional decline
• Signs persist for at least 6 months
• Other disorders ruled out

Challenges in Diagnosis

• Symptoms overlap with other conditions
• Substance use can complicate diagnosis
• Cultural factors may influence presentation
• People may lack insight into illness
• Stigma may delay help-seeking

Schizophrenia requires lifelong treatment, even when symptoms have subsided. Treatment with medications and psychosocial therapy can help manage the condition. In crisis periods or times of severe symptoms, hospitalization may be necessary.

Medications

Antipsychotic Medications

The primary treatment for schizophrenia:

Second-Generation (Atypical) Antipsychotics

• Risperidone (Risperdal)
• Olanzapine (Zyprexa)
• Quetiapine (Seroquel)
• Aripiprazole (Abilify)
• Clozapine (Clozaril) - for treatment-resistant cases
• Paliperidone (Invega)
• Lurasidone (Latuda)

First-Generation (Typical) Antipsychotics

• Haloperidol (Haldol)
• Chlorpromazine
• Fluphenazine
• Often have more neurological side effects

Long-Acting Injectable Medications

• Given every 2-4 weeks or monthly
• Improves medication adherence
• Reduces relapse rates

Psychosocial Interventions

Individual Therapy

• Cognitive Behavioral Therapy (CBT): Helps normalize thought patterns
• Cognitive Enhancement Therapy: Improves cognitive functioning
• Personal therapy: Focuses on social skills and stress management
