Study Notes
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
Definition and Prevalence of Schizophrenia

Symptoms of Schizophrenia
- Positive symptoms:
- Hallucinations, such as hearing voices or seeing things that are not there.
- Delusions, which are false beliefs.
- Disorganized thinking and speech.
- Negative symptoms:
- Apathy, or a lack of motivation.
- Emotional flattening, or a lack of emotional response.
- Cognitive symptoms:
- Difficulty with attention and processing information.
- Memory problems.
Causes and Risk Factors of Schizophrenia
- Genetic factors: Family history and genetic mutations increase the risk of developing schizophrenia.
- Environmental factors: Prenatal complications, childhood trauma, and social isolation can contribute to the development of the disorder.
- 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.
- Psychosocial therapies, such as cognitive-behavioral and family-focused therapies.
- Electroconvulsive therapy (ECT) in some cases.
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.
