  • Brain structure
    • Enlarged ventricles
    • meta - analysis by Raz and Raz found that over 1/2 of individuals tested with scz had increased ventricle size compared to control group.
    • Enlarged ventricles are associated with damage to central brain areas and pre-frontal cortex, this damage is associated with negative symptoms
  • Brain structure A03
    RTS comes from Suddath et al. Used MRI scans to investigate the brain structure of MZ twins in which one twin was scz. They found the scz twin generally had more enlarged ventricles. Suggesting enlarged ventricles do play a role in determining the likelihood of schizophrenia developing.
