Alterations of cerebral white matter structure in psychosis and their clinical correlations: a systematic review of Diffusion Tensor Imaging studies

Year: 2017

Type: review

Abstract: Schizophrenia is a common, severe and chronically disabling mental illness. Most of MRI studies in schizophrenia suggest the involvement of white matter (WM) pathology in multiple cerebral regions in the neurobiology of this condition. White matter fiber tracts connecting numerous cortical regions have been the focus of a number of studies using a magnetic resonance technique called “Diffusion Tensor Imaging” (DTI). A literature search of published DTI studies was conducted using the major database National Centre for Biotechnology information (NCBI) PubMed (MEDLINE). Our review covers 95 published papers. We summarise the main DTI findings involving the different brain regions in patients affected by or at high-risk for psychosis; we discuss clinical implications of these white matter disruptions and the limitations of current studies, listing the potential confounds and suggesting potential future research directions.
