Recent studies have used fMRI to explore specific brain networks, such as the salience network and default mode network, to understand their roles in schizophrenia-related symptoms. Alterations in these networks may affect self-referential thoughts and responses to external stimuli, potentially contributing to symptoms like hallucinations and ...
Brain imaging, such as CT and MRI scans, are currently only used to rule out brain abnormalities, and their benefit is very limited at that. [46] Structural alterations have, however, been identified in schizophrenia, most commonly enlarged ventricles, and decreased grey matter volume in the cortex and hippocampus. [47]

People with schizophrenia are commonly exploited and victimized by violent crime as part of a broader dynamic of social exclusion. [25] [26] People diagnosed with schizophrenia are also subject to forced drug injections, seclusion, and restraint at high rates. [31] [32] The risk of violence by people with schizophrenia is small.
