Schizophrenia symptoms are categorized into positive (abnormal additions to behavior), negative (loss of normal functions), and cognitive:

• Positive Symptoms:
  • Hallucinations: Auditory (hearing voices) or visual disturbances.
  • Delusions: Fixed false beliefs (e.g., paranoia, grandiosity).
  • Disorganized Thinking/Speech: Incoherent or tangential language.
  • Abnormal Motor Behavior: Agitation, catatonia, or repetitive movements.
• Negative Symptoms:
  • Affective Flattening: Reduced emotional expression.
  • Avolition: Lack of motivation or goal-directed behavior.
  • Alogia: Poverty of speech.
• Cognitive Symptoms:
  • Impaired memory, attention, or executive functioning (Mayo Clinic).

Red Flags:

• Suicidal ideation, self-harm, or complete social withdrawal require urgent intervention (Lippincott Review of Pathology).

Schizophrenia arises from a complex interplay of genetic, neurobiological, and environmental factors:

1. Genetic Predisposition:
   • Family history increases risk; over 100 gene variants implicated (e.g., COMT, DISC1).
2. Neurochemical Imbalances:
   • Dysregulation of dopamine, glutamate, and serotonin pathways.
3. Environmental Triggers:
   • Prenatal Factors: Maternal infections, malnutrition, or stress.
   • Childhood Adversity: Trauma, abuse, or urban upbringing.
   • Substance Use: Cannabis use in adolescence (linked to earlier onset).
4. Brain Abnormalities:
   • Enlarged ventricles, reduced gray matter volume (WHO).

While schizophrenia cannot be fully prevented, early intervention may mitigate severity:

1. Early Psychosis Intervention:
   • Address prodromal symptoms (e.g., social withdrawal, odd beliefs) with counseling.
2. Avoid Substance Abuse:
   • Discourage cannabis use, particularly in high-risk adolescents.
3. Prenatal Care:
   • Ensure maternal nutrition and infection control (Lippincott Textbook of Pharmacology).

1. Antipsychotic Medications:

• First-Generation (Typical): Haloperidol, chlorpromazine (block dopamine D2 receptors).
• Second-Generation (Atypical):
  • Risperidone, olanzapine, quetiapine (target dopamine and serotonin receptors).
  • Clozapine: For treatment-resistant cases (requires blood monitoring for agranulocytosis) (BNF).
• Long-Acting Injectables (LAIs): Aripiprazole or paliperidone to improve adherence.

2. Psychosocial Therapies:

• Cognitive Behavioral Therapy (CBT): Challenges delusions and improves coping.
• Family Therapy: Educates caregivers and reduces relapse risk.
• Social Skills Training: Enhances communication and daily living skills (WHO).

3. Rehabilitation Programs:

• Vocational training and supported employment to promote independence.

4. Monitoring & Side Effect Management:

• Metabolic Syndrome: Monitor weight, blood glucose, and lipids (common with olanzapine).
• Extrapyramidal Symptoms (EPS): Treat with anticholinergics (e.g., benztropine) (Lange Textbook of Clinical Pharmacology).

• Worsening Symptoms: Increased frequency of psychotic episodes.
• Social Isolation: Loss of relationships or housing.
• Suicide: 5–10% lifetime risk (Mayo Clinic).

Schizophrenia requires lifelong, multidisciplinary management combining antipsychotics, psychosocial support, and community resources. Early diagnosis and tailored treatment plans can improve functional outcomes and quality of life. Patients and families should work closely with mental health professionals to navigate challenges and reduce stigma.
