Aberrant cerebro-cerebellar functional connectivity and minimal self-disturbance in individuals at ultra-high risk for psychosis and with first-episode schizophrenia.

Schizophrenia Research December 1, 2018 Minji Bang, Hae-Jeong Park, Chongwon Pae et al. 23 citations

Minimal self-disturbance, a core feature of schizophrenia, is linked to altered connectivity between the cerebellum and the brain's default mode network. In a resting-state fMRI study, individuals at ultra-high risk for psychosis and first-episode schizophrenia patients showed reduced cerebellar functional connectivity with the presupplementary motor area, anterior prefrontal cortex, and precuneus compared to healthy controls. Ultra-high-risk individuals exhibited intermediate reductions. Minimal self-disturbance severity, similar in both clinical groups, correlated with these connectivity patterns, though the associations differed between groups. Aberrant cerebro-cerebellar connectivity may offer insights into schizophrenia's core pathology and help predict psychosis in at-risk individuals.

Interplay of Subjective Symptoms Across the Stages of the Schizophrenia Spectrum.

Psychiatry Investigation May 1, 2026 Hye Yoon Park, Minji Bang, Suk Kyoon An

People with schizophrenia spectrum disorders and those at ultra-high risk for psychosis both report elevated levels of disturbed self-experience, cognitive complaints, and schizotypy compared to healthy controls. Healthy controls scored significantly lower on the Examination of Anomalous Self-Experience (EASE), the Frankfurt Complaint Questionnaire (FBF), and the Chapman Psychosis Proneness Scales (CPPS). Differences between the ultra-high risk and schizophrenia groups on these measures were not statistically significant. Stronger associations among the three measures were observed in the schizophrenia group. The findings indicate a continuous spectrum of shared experiential anomalies and support integrated assessment approaches for early psychosis detection.
