Abstract
Chromosome 22q11.2 deletion is among the strongest known genetic risk factors for neuropsychiatric disorders, including autism and schizophrenia. Brain imaging studies have reported disrupted large-scale functional connectivity in people with 22q11 deletion syndrome (22q11DS). However, the significance and biological determinants of these functional alterations remain unclear. Here, we use a cross-species design to investigate the developmental trajectory and neural underpinnings of brain dysconnectivity in 22q11DS. We find that LgDel mice, an established mouse model of 22q11DS, exhibit age-specific patterns of functional MRI (fMRI) dysconnectivity, with widespread fMRI hyper-connectivity in juvenile mice reverting to focal hippocampal hypoconnectivity over puberty. These fMRI connectivity alterations are mirrored by co-occurring developmental alterations in dendritic spine density, and are both transiently normalized by developmental GSK3β inhibition, suggesting a synaptic origin for this phenomenon. Notably, analogous hyper- to hypoconnectivity reconfiguration occurs also in human 22q11DS, where it affects hippocampal and cortical regions spatially enriched for synaptic genes that interact with GSK3β, and autism-relevant transcripts. Functional dysconnectivity in somatomotor components of this network is predictive of age-dependent social alterations in 22q11.2 deletion carriers. Taken together, these findings suggest that synaptic-related mechanisms underlie developmentally mediated functional dysconnectivity in 22q11DS.

Abstract
OBJECTIVE Previous research has uncovered relationships between religion/spirituality and depressive disorders. Proposed mechanisms through which religion may impact depression include decreased substance use and enhanced social support. Little investigation of these topics has occurred with adolescent psychiatric patients, among whom depression, substance use, and social dysfunction are common. METHOD 145 subjects, aged 12-18, from two psychiatric outpatient clinics completed the Beck Depression Inventory-II (BDI-II), the Fetzer multidimensional survey of religion/spirituality, and inventories of substance abuse and perceived social support. Measures were completed again six months later. Longitudinal and cross-sectional relationships between depression and religion were examined, controlling for substance abuse and social support. RESULTS Of thirteen religious/spiritual characteristics assessed, nine showed strong cross-sectional relationships to BDI-II score. When perceived social support and substance abuse were controlled for, forgiveness, negative religious support, loss of faith, and negative religious coping retained significant relationships to BDI-II. In longitudinal analyses, loss of faith predicted less improvement in depression scores over 6 months, controlling for depression at study entry. LIMITATIONS Self-report data, clinical sample. CONCLUSIONS Several aspects of religiousness/spirituality appear to relate cross-sectionally to depressive symptoms in adolescent psychiatric patients. Findings suggest that perceived social support and substance abuse account for some of these correlations but do not explain relationships to negative religious coping, loss of faith, or forgiveness. Endorsing a loss of faith may be a marker of poor prognosis among depressed youth.
