Additionally, Schizophrenia does not have a single cause. It arises from a complex interplay of genetic, biological, and environmental factors.

1. Genetic Factors

• People with a family history of schizophrenia are at a higher risk.
• Having a first-degree relative (e.g., parent or sibling) increases risk by 10%.

• Unsafe childhood encounters.
• Brain damage, sexual maltreatment, and awful early encounters

Treatment of Schizophrenia

Although schizophrenia has no cure, effective treatment and management can help individuals lead productive lives.

1. Medications

• Antipsychotics: First-line treatment for reducing psychotic symptoms.
  • First-generation (e.g., Haloperidol)
  • Second-generation (e.g., Risperidone, Olanzapine)
• Side Effects: Weight gain, tremors, and drowsiness.

2. Psychotherapy

• Cognitive Behavioral Therapy (CBT): Helps change negative thought patterns.
• Family Therapy: Educates families and strengthens support systems.
• Social Skills Training: Enhances communication and daily functioning.

3. Community Support Programs
