Abstract
Theoretical psychiatry considers theoretical problems in psychiatry as well as the quality and effectiveness of mental health care. This chapter addresses the idea of predictive, preventive, precision, personalized, and participatory medicine in psychiatry from a theoretical transdisciplinary integrative perspective and systems networking. The aim of the chapter is to bring together some current ideas and concepts such as computational neuroscience, network theory, multi-omics profile, precision medicine, and person-centered psychiatry as a coherent system of theory and practice.

Am J Med Genet B Neuropsychiatr Genet 2019; 180:46-54. [PMID: 30556376 DOI: 10.1002/ajmg.b.32702] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 09/28/2018] [Accepted: 11/09/2018] [Indexed: 12/14/2022]
Abstract
Many genetic conditions can mimic mental health disorders, with psychiatric symptoms that are difficult to treat with standard psychotropic medications. This study tests the hypothesis that psychiatric populations are enriched for pathogenic variants associated with selected inborn errors of metabolism (IEMs). Using next-generation sequencing, 2046 psychiatric patients were screened for pathogenic variants in genes associated with four IEMs, Niemann-Pick disease type C (NPC), Wilson disease (WD), homocystinuria (HOM), and acute intermittent porphyria (AIP). Among the 2046 cases, carrier rates of 0.83, 0.98, and 0.20%, for NPC, WD and HOM, and affected rates of 0.10 and 0.24% for NPC and AIP were seen, respectively. An enrichment of known and predicted pathogenic variants in the genes associated with NPC and AIP was found in the psychiatric cohort and especially in schizophrenia patients. The results of this study support that pathogenic variants in genes associated with IEMs are enriched in psychiatric populations. Underlying undiagnosed IEMs could account for the psychiatric symptomatology in a subset of psychiatric patients. Further studies are warranted to investigate the possibility that carriers for IEMs may have an increased risk for psychiatric disorders, particularly in the context of poor treatment response.

Raouna A, Osam CS, MacBeth A. Clinical staging model in offspring of parents with bipolar disorder: a systematic review. Bipolar Disord 2018; 20:313-333. [PMID: 29446217 DOI: 10.1111/bdi.12604] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2017] [Revised: 12/09/2017] [Indexed: 12/30/2022]
Abstract
OBJECTIVE We sought to systematically review the literature on the psychiatric risk of offspring of parents with bipolar disorder (OPBD) using a developmental psychopathology framework. The review also sought to establish the utility of clinical stage modelling as a framework for identifying precursor disorders to later onset of bipolar disorder (BD) in OPBD. METHODS A systematic search was performed using EMBASE, PsychINFO and Medline. Reference lists of included studies and previous reviews were also searched. Studies were included if they reported diagnostic outcomes for child, adolescent and young adult offspring of parents diagnosed with BD. RESULTS Twenty-six studies were identified representing 21 individual cohorts. The review identified that OBPD present as a high-risk group for a range of mood and non-mood disorders in childhood, adolescence and young adulthood. The trajectory of risk was from non-mood disorders in childhood via non-bipolar mood disorders in early adolescence towards mania/hypomania in late adolescence and early adulthood. From a clinical staging perspective, childhood anxiety disorders were associated with later onset of BD. Recurrent substance use disorder was identified as a risk in OPBD during late adolescence and early adulthood. Quality ratings indicated that studies were methodologically robust. CONCLUSIONS Our review provides evidence for a developmental psychopathology trajectory of precursor risks to BD in OPBD. There is support for clinical stage modelling as a conceptual framework for understanding developmental risk in OPBD and as a tool for developing early and individualized intervention strategies.

Abstract
OBJECTIVE We aimed to review clinical features and biological underpinnings related to neuroprogression in bipolar disorder (BD). Also, we discussed areas of controversy and future research in the field. METHOD We systematically reviewed the extant literature pertaining to neuroprogression and BD by searching PubMed and EMBASE for articles published up to March 2016. RESULTS A total of 114 studies were included. Neuroimaging and clinical evidence from cross-sectional and longitudinal studies show that a subset of patients with BD presents a neuroprogressive course with brain changes and unfavorable outcomes. Risk factors associated with these unfavorable outcomes are number of mood episodes, early trauma, and psychiatric and clinical comorbidity. CONCLUSION Illness trajectories are largely variable, and illness progression is not a general rule in BD. The number of manic episodes seems to be the clinical marker more robustly associated with neuroprogression in BD. However, the majority of the evidence came from cross-sectional studies that are prone to bias. Longitudinal studies may help to identify signatures of neuroprogression and integrate findings from the field of neuroimaging, neurocognition, and biomarkers.
