The Limits between Schizophrenia and Bipolar Disorder: What Do Magnetic Resonance Findings Tell Us?

State of the art in psychological therapies for psychosis: Family interventions for psychosis

PURPOSE

It is a half-century since the coalescence of social psychiatry and systemic family therapy approaches started to inform condition-specific therapeutic work with families to reduce relapse and hospital readmission for people with schizophrenia. Today, family interventions are a cornerstone of international guidelines for the treatment of psychosis, and of workforce development initiatives. Effect sizes for clinical and economic outcomes are large, and the evidence base is robust and reliable, not only for outcomes but also for the underpinning theoretical models, which are coherent and consistent. Few, if any, psychological therapies, have so powerful a framework to drive widespread implementation. Nevertheless, delivery in clinical services is variable, often lagging behind that of individual cognitive behavioural therapy, notwithstanding its considerably weaker implementation framework. Our aim in this article is to formulate this translation failure and offer potential solutions.

METHOD

We summarise the model/intervention and supporting evidence, then consider why delivery remains problematic.

RESULTS

We highlight the inter-linked issues of conceptual confusion between and conflation of, different approaches to working with families; of addressing diagnostic uncertainty, complex comorbidity and adapting interventions for specific populations; and of translation from gold-standard research trial practice, through educational curricula and training programmes, to routine delivery in frontline services.

CONCLUSION

We present our view of clinical, research and workforce development priorities to address these issues and continue the collective effort, moving into the next half-century, to work more effectively with people with psychosis and their families, to further improve outcomes.

Factors associated with suicide attempts in the antecedent illness trajectory of bipolar disorder and schizophrenia

BACKGROUND

Factors associated with suicide attempts during the antecedent illness trajectory of bipolar disorder (BD) and schizophrenia (SZ) are poorly understood.

METHODS

Utilizing the Rochester Epidemiology Project, individuals born after 1985 in Olmsted County, MN, presented with first episode mania (FEM) or psychosis (FEP), subsequently diagnosed with BD or SZ were identified. Patient demographics, suicidal ideation with plan, self-harm, suicide attempts, psychiatric hospitalizations, substance use, and childhood adversities were quantified using the electronic health record. Analyses pooled BD and SZ groups with a transdiagnostic approach given the two diseases were not yet differentiated. Factors associated with suicide attempts were examined using bivariate methods and multivariable logistic regression modeling.

RESULTS

A total of 205 individuals with FEM or FEP (BD = 74, SZ = 131) were included. Suicide attempts were identified in 39 (19%) patients. Those with suicide attempts during antecedent illness trajectory were more likely to be female, victims of domestic violence or bullying behavior, and have higher rates of psychiatric hospitalizations, suicidal ideation with plan and/or self-harm, as well as alcohol, drug, and nicotine use before FEM/FEP onset. Based on multivariable logistic regression, three factors remained independently associated with suicidal attempts: psychiatric hospitalization (OR = 5.84, 95% CI 2.09-16.33, p < 0.001), self-harm (OR = 3.46, 95% CI 1.29-9.30, p = 0.014), and nicotine use (OR = 3.02, 95% CI 1.17-7.76, p = 0.022).

CONCLUSION

Suicidal attempts were prevalent during the antecedents of BD and SZ and were associated with several risk factors before FEM/FEP. Their clinical recognition could contribute to improve early prediction and prevention of suicide during the antecedent illness trajectory of BD and SZ.

Brain Hemispheric Asymmetry in Schizophrenia and Bipolar Disorder

BACKGROUND

This study aimed to compare brain asymmetry in patients with schizophrenia (SCZ), bipolar disorder (BPD), and healthy controls to test whether asymmetry patterns could discriminate and set boundaries between two partially overlapping severe mental disorders.

METHODS

We applied a fully automated voxel-based morphometry (VBM) approach to assess structural brain hemispheric asymmetry in magnetic resonance imaging (MRI) anatomical scans in 60 participants (SCZ = 20; BP = 20; healthy controls = 20), all right-handed and matched for gender, age, and education.

RESULTS

Significant differences in gray matter asymmetry were found between patients with SCZ and BPD, between SCZ patients and healthy controls (HC), and between BPD patients and HC. We found a higher asymmetry index (AI) in BPD patients when compared to SCZ in Brodmann areas 6, 11, and 37 and anterior cingulate cortex and an AI higher in SCZ patients when compared to BPD in the cerebellum.

CONCLUSION

Our study found significant differences in brain asymmetry between patients with SCZ and BPD. These promising results could be translated to clinical practice, given that structural brain changes detected by MRI are good candidates for exploration as biological markers for differential diagnosis, besides helping to understand disease-specific abnormalities.
