Factors Moderating the Association between Cannabis Use and Psychosis Risk: A Systematic Review
Brain Science, 2020 Increasing evidence indicates a relationship between cannabis use and psychosis risk. Specific factors, such as determinants of cannabis use or the genetic profile of cannabis users, appear to moderate this association.

Community Detection in Weighted Multilayer Networks with Ambient Noise [PDF]
arXiv, 2021 We introduce a novel model for multilayer weighted networks that accounts for global noise in addition to local signals. The model is similar to a multilayer stochastic blockmodel (SBM), but the key difference is that between-block interactions independent across layers are common for the whole system, which we call ambient noise.

How Predictable are Symptoms in Psychopathological Networks? A Reanalysis of 18 Published Datasets [PDF]
arXiv, 2016 Background Network analyses on psychopathological data focus on the network structure and its derivatives such as node centrality. One conclusion one can draw from centrality measures is that the node with the highest centrality is likely to be the node that is determined most by its neighboring nodes. However, centrality is a relative measure: knowing

Nature Communications, 2018 Understanding the fundamental alterations in brain functioning that lead to psychotic disorders remains a major challenge in clinical neuroscience. In particular, it is unknown whether any state-independent biomarkers can potentially predict the onset of

Quantifying word salad: The structural randomness of verbal reports predicts negative symptoms and Schizophrenia diagnosis 6 months later [PDF]
arXiv, 2016 Background: The precise quantification of negative symptoms is necessary to improve differential diagnosis and prognosis prediction in Schizophrenia. In chronic psychotic patients, the representation of verbal reports as word graphs provides automated sorting of schizophrenia, bipolar disorder and control groups based on the degree of speech ...
