Frontostriatal Dysconnectivity in adolescent Onset Schizophrenia and its Associations with Cognition: An MRI Volumetric and Diffusion Tensor Imaging Study
Published online by Cambridge University Press: 23 March 2020
Abstract
Adolescent-onset schizophrenia (AOS) is associated with cognitive impairment and poor clinical outcome. Cognitive dysfunction is thought to reflect functional dysconnectivity between the frontal cortex and the striatum, Previous work [1] has shown frontostriatal dysconnectivity in large WM tracts explain core cognitive deficits, with processing speed, which is affected by alterations in WM connectivity, being an intermediary variable.
To undertake a follow-up MRI study using whole-brain structural connectomics to track topological changes in the follow-up (1st episode versus follow-up), in order to characterize the early stages (evolution of the first two years) of the disorder.
A follow-up study of 25 AOS subjects and 25 age and sex-matched healthy subjects.
Network theory will be applied to identify topological alterations in structural networks, including frontostriatal white matter (WM) tracts in relation to cognition and outcome measures.
