    Psychiatric Iowa Neuroimaging Consortium, The University of Iowa Carver College of Medicine, Iowa City, Iowa 52242, USA
    Biol Psychiatry 70:672-9. 2011
    ..Structural magnetic resonance studies indicate that brain abnormalities are present at onset, but longitudinal studies to assess neuroprogression have been limited by small samples and short or infrequent follow-up intervals...

    Nancy C Andreasen
    Department of Psychiatry, Roy J and Lucille A Carver College of Medicine, The University of Iowa, Iowa City, Iowa, USA
    Biol Psychiatry 64:81-8. 2008
    ..Evidence indicating that cerebellar abnormalities occur in schizophrenia is also reviewed. These suggest interesting directions for future research...
