Schizophrenia Overview

Definition and Prevalence

• Schizophrenia is a chronic and severe mental disorder characterized by distortions in thinking, perception, and emotions.
• Affects approximately 1% of the global population.
• Typically develops in late adolescence or early adulthood.

Symptoms

• Positive symptoms:
  • Hallucinations (hearing voices, seeing things that are not there)
  • Delusions (false beliefs)
  • Disorganized thinking and speech
• Negative symptoms:
  • Apathy
  • Lack of motivation
  • Emotional flattening
• Cognitive symptoms:
  • Difficulty with attention, memory, and processing information

Causes and Risk Factors

• Genetic factors: Family history, genetic mutations
• Environmental factors: Prenatal complications, childhood trauma, social isolation
• Brain structure and function: Abnormalities in brain regions, neurotransmitter imbalances

Diagnosis and Treatment

• Diagnostic criteria: Meeting certain symptoms for a specified duration (e.g., 6 months)
• Treatment options:
  • Antipsychotic medications
  • Psychosocial therapies (cognitive-behavioral, family-focused)
  • Electroconvulsive therapy (ECT) in some cases

Complications and Prognosis

• Co-occurring disorders: Depression, anxiety, substance abuse
• Social and occupational impairment: Difficulty maintaining relationships, holding a job
• Prognosis: Varied, ranging from significant improvement to chronic disability
• Suicide risk: Elevated in individuals with schizophrenia, particularly during acute episodes

Causes and Risk Factors of Schizophrenia

• Genetic factors: Family history and genetic mutations increase the risk of developing schizophrenia.

• Brain structure and function: Abnormalities in brain regions and neurotransmitter imbalances can also play a role.

Diagnosis and Treatment of Schizophrenia

• Diagnostic criteria: Meeting certain symptoms for a specified duration, typically 6 months.
• Treatment options:
  • Antipsychotic medications to reduce symptoms.

Complications and Prognosis of Schizophrenia

• Co-occurring disorders: Depression, anxiety, and substance abuse are common comorbidities.
• Social and occupational impairment: Difficulty maintaining relationships and holding a job are common complications.
• Prognosis: Varied, ranging from significant improvement to chronic disability.
• Suicide risk: Elevated in individuals with schizophrenia, particularly during acute episodes.
