Question

all of the following factors are suggested as potential contributing causes of schizophrenia except?
○ genetic inheritance
○ family violence
○ stress in people predisposed to the disorder
○ excessive dopamine activity

Explanation:

To determine the answer, we analyze each option:

• Genetic inheritance: Research shows a genetic component in schizophrenia, with a higher risk for those with family history.
• Family violence: There's no established link between family violence and schizophrenia causation. Schizophrenia is more related to genetic, neurochemical (like dopamine), and stress in predisposed individuals.
• Stress in predisposed: Stress can trigger schizophrenia in those with a genetic predisposition.
• Excessive dopamine: The dopamine hypothesis suggests excessive dopamine activity is linked to schizophrenia symptoms.

Answer:

B. family violence
