Final answer:
The false statement about schizophrenia and ventricular changes is that ventricular changes are not associated with schizophrenia. Enlargement of ventricles is commonly observed, and changes in ventricular size can be markers of disease progression or improvement.
Step-by-step explanation:
The correct answer is option b: Ventricular changes are not associated with schizophrenia. This statement is false. Research on brain abnormalities in patients with schizophrenia has frequently found an enlargement of the ventricles, which is supported by volumetric magnetic resonance imaging studies. This enlargement is sometimes used as a marker for the progression of the disease. Furthermore, there is some evidence to suggest that a reduction in ventricular size could be linked to improvement in schizophrenia symptoms, although more research is needed to fully understand this relationship.
