Statement of the Problem:
Age of onset has a significant influence on the course and overall outcome in schizophrenia. However,
the similarities and differences in the pathophysiology of early-onset (EOS) and adult-onset schizophrenia (AOS) remain elusive.
The purpose of this study was to characterize the convergent neurobiological abnormalities in EOS and AOS as compared to their
respective healthy controls by using a multimodal MRI approach; combined VBM, DTI and fMRI techniques.
Methodology &Theoretical Orientation:
Using Magnetic Resonance Imaging, we investigated the gray matter morphometry, white
matter integrity and functional connectivity in 73 participants; 17 patients with EOS and 20 with AOS were compared with age-, sex-,
and educational status - matched healthy controls (HC) (n=16 and 20, respectively).
Findings:
The superior temporal gyrus (STG) showed convergent structural and functional impairment in in both EOS and AOS
as compared to their respective HC. In a direct comparison between EOS and AOS, we found the EOS group to exhibit wider and
increased FC of the STG, especially with the sensorimotor areas, default mode, visual recognition, subcortical and the auditory
networks. The functional connections that exhibited hypo-connectivity in the EOS group were found to be correlated with clinical
symptoms.
Conclusion & Significance:
The variations in the structural and functional connectivity of this region in EOS and AOS subjects may
explain the differences in psychopathology and treatment outcomes between these patients groups.
