Altered cortical thickness development in 22q11.2 deletion syndrome and association with psychotic symptoms

Maude Schneider, Marie Schaer, Daniela Maria Zöller, Maria Carmela Padula

Schizophrenia has been extensively associated with reduced cortical thickness (CT), and its neurodevelopmental origin is increasingly acknowledged. However, the exact timing and extent of alterations occurring in preclinical phases remain unclear. With a h ...

Long-term effects of early treatment with SSRIs on cognition and brain development in individuals with 22q11.2 deletion syndrome

Maude Schneider, Marie Schaer, Karin Bortolin

Cognitive deficits in individuals at risk of psychosis represent a significant challenge for research, as current strategies for symptomatic treatment are often ineffective. Recent studies showed that atypical cognitive development predicts the occurrence ...

Structural control energy of resting-state functional brain states reveals less cost-effective brain dynamics in psychosis vulnerability

Dimitri Nestor Alice Van De Ville, Marie Schaer

How the brain's white-matter anatomy constrains brain activity is an open question that might give insights into the mechanisms that underlie mental disorders such as schizophrenia. Chromosome 22q11.2 deletion syndrome (22q11DS) is a neurodevelopmental dis ...

WILEY2021

Dynamic spatiotemporal patterns of brain connectivity reorganize across development

Alessandra Griffa, Patric Hagmann, Marie Schaer, Emeline Mullier

Late human development is characterized by the maturation of high-level functional processes, which rely on reshaping of white matter connections, as well as synaptic density. However, the relationship between the whole-brain dynamics and the underlying wh ...

Identifying neurodevelopmental anomalies of white matter microstructure associated with high risk for psychosis in 22q11.2DS

Maude Schneider, Marie Schaer, Daniela Maria Zöller, Maria Carmela Padula

Disruptions of white matter microstructure have been widely reported in schizophrenia. However, the emergence of these alterations during preclinical stages remains poorly understood. 22q11.2 Deletion Syndrome (22q11.2DS) represents a unique model to study ...

Abnormal Development and Dysconnectivity of Distinct Thalamic Nuclei in Patients With 22q11.2 Deletion Syndrome Experiencing Auditory Hallucinations

Maude Schneider, Marie Schaer

BACKGROUND: Several studies in patients with schizophrenia have demonstrated an abnormal thalamic volume and thalamocortical connectivity. Specifically, hyperconnectivity with somatosensory areas has been related to the presence of auditory hallucinations ...

Large-Scale Brain Network Dynamics Provide a Measure of Psychosis and Anxiety in 22q11.2 Deletion Syndrome Daniela

Dimitri Nestor Alice Van De Ville, Marie Schaer, Fikret Isik Karahanoglu, Maria Carmela Padula

BACKGROUND: Prodromal positive psychotic symptoms and anxiety are two strong risk factors for schizophrenia in 22q11.2 deletion syndrome (22q11DS). The analysis of large-scale brain network dynamics during rest is promising to investigate aberrant brain fu ...

Robust Recovery of Temporal Overlap Between Network Activity Using Transient-Informed Spatio-Temporal Regression

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Marie Schaer, Fikret Isik Karahanoglu, Daniela Maria Zöller

Functional magnetic resonance imaging is a non-invasive tomographic imaging modality that has provided insights into system-level brain function. New analysis methods are emerging to study the dynamic behavior of brain activity. The innovation-driven co-ac ...
