🎧 A clear, high-yield breakdown of this chronic psychiatric condition with psychotic features – perfect for exam prep and clinical understanding!
🧠 Key Learning Points
📌 Definition
• Schizophrenia is a chronic, severe psychiatric disorder marked by episodes of psychosis, including hallucinations, delusions, and disordered thinking, with functional and social impairment.
📌 Causes & Risk Factors
• Genetic predisposition (e.g. 7.5x risk if parent affected, ~50% if monozygotic twin)
• Neurotransmitter dysregulation – dopamine and glutamate
• Environmental factors – obstetric complications, urban upbringing, social isolation
• Cannabis use (RR ~1.4), trauma, childhood adversity
• Higher prevalence in some ethnic groups and migrants
🧠 Mnemonic: "GENES-DOPE" – Genes, Environment, Neurotransmitters, Early Stress, Drugs (Cannabis), Obstetrics, Psychosocial, Ethnicity
📌 Pathophysiology
• Abnormalities in dopamine and glutamate neurotransmission
• Structural and functional changes in:
– Prefrontal cortex (planning/thinking)
– Hippocampus (memory/emotion)
– Striatum (motivation/reward)
• Disruption in cognitive, emotional, and perceptual regulation
📌 Symptoms
• Positive: hallucinations (commonly auditory), delusions, disorganized speech/behavior, passivity phenomena
• Negative: apathy, social withdrawal, reduced emotional expression, self-neglect
• Cognitive: poor memory, impaired attention
• Prodromal phase may precede full psychosis
🧠 Mnemonic: "HDD-PANS" – Hallucinations, Delusions, Disorganised speech + Passivity, Apathy, Negative affect, Social withdrawal
📌 Differential Diagnosis
• Organic causes: drug-induced psychosis (LSD, amphetamines, cannabis), epilepsy, encephalitis, dementia, delirium, syphilis
• Psychiatric: Bipolar disorder (mania), psychotic depression, dissociative identity disorder
• Comorbidities: Depression, anxiety, substance misuse, physical health issues (DM, CVD)
📌 Diagnosis
• Clinical diagnosis based on DSM-5 or ICD-10/11
• Look for first-rank symptoms (Schneider) – e.g. thought insertion, thought withdrawal, auditory hallucinations (voices commenting)
• PANSS scale for symptom quantification
• Investigations (rule out differentials):
– Bloods: FBC, U&Es, TFTs, calcium
– Urine drug screen
– MRI/CT if organic cause suspected
– ECG and baseline monitoring before antipsychotics
📌 Management
• Antipsychotics (1st line): risperidone, olanzapine
• Treatment-resistant: Clozapine
• Psychological: CBT (offered to all), family therapy, psychoeducation
• Social: housing, vocational training, financial & employment support
• Shared care between GP and psychiatry
• Specialist teams: crisis resolution, home treatment, community mental health
🧠 Mnemonic: "MAPS" – Medication, Assessment, Psychological support, Social care
📌 Complications
• Relapse, social withdrawal, chronic disability
• Substance misuse
• Suicide and self-harm
• Metabolic syndrome, diabetes, CVD (linked to antipsychotics)
• Reduced life expectancy
📌 Prognosis
• Variable course – can be episodic or chronic
• Better prognosis: acute onset, good premorbid function, mood symptoms, early treatment
• Poorer prognosis: early/insidious onset, male sex, negative symptoms, substance use
• Long-term support often required
