Final answer:
Brain scans show enlarged ventricles in individuals with schizophrenia, which can affect brain function and contribute to symptoms of the disorder.
Step-by-step explanation:
Brain scans have found enlarged fluid-filled areas, specifically in the ventricles, in people with schizophrenia. These scans, often involving techniques such as magnetic resonance imaging (MRI), reveal structural abnormalities that are associated with certain mental health conditions. The enlargement of these areas can lead to disruptions in normal brain function, which may partly explain the symptoms experienced by individuals with schizophrenia.
