ABSTRACT Recent theories suggest that children with pediatric bipolar disorder (PBD) may exhibit more difficult temperaments premorbidly, including traits such as behavioral disinhibition and difficulty with emotion regulation. We investigated temperament characteristics retrospectively during infancy and toddlerhood in subjects with PBD (n=25), attention-deficit/hyperactivity disorder (ADHD; n=25), and healthy controls (n=25). Children with PBD were reported to experience increased difficult temperament in both infancy and toddlerhood compared to children with ADHD. Several characteristics of difficult temperament were associated with residual symptoms of mania and depression. Difficult premorbid temperament characteristics may be a specific indicator of a bipolar diathesis, or might signal underlying dysfunction in affective processes that significantly increase risk for a mood disorder.

    ABSTRACT: Research on pediatric bipolar disorder (PBD) is providing a plethora of empirical findings regarding its comorbidity. We addressed this question through a systematic review concerning the prevalence, clinical impact, etiology and treatment of main comorbid disorders involved. A comprehensive database search was performed from 1990 to August 2014. Overall, 167 studies fulfilled the inclusion criteria. Bipolar youth tend to suffer from comorbid disorders, with highest weighted mean prevalence rate arising from anxiety disorders (54%), followed by attention deficit hyperactivity disorder (ADHD) (48%), disruptive behavior disorders (31%), and substance use disorders (SUD) (31%). Furthermore, evidence indicates that ADHD and anxiety disorders negatively affect the symptomatology, neurocognitive profile, clinical course and the global functioning of PBD. Likewise, several theories have been posited to explain comorbidity rates in PBD, specifically common risk factors, one disorder being a risk factor for the other and nosological artefacts. Lastly, randomized controlled trials highlight a stronger therapeutic response to stimulants and atomoxetine (vs. placebo) as adjunctive interventions for comorbid ADHD symptoms. In addition, research focused on the treatment of other comorbid disorders postulates some benefits from mood stabilizers and/or SGA. Epidemiologic follow-up studies are needed to avoid the risk of nosological artefacts. Likewise, more research is needed on pervasive developmental disorders and anxiety disorders, especially regarding their etiology and treatment. Psychiatric comorbidity is highly prevalent and is associated with a deleterious clinical effect on pediatric bipolarity. Different etiological pathways may explain the presence of these comorbid disorders among bipolar youth. Standardized treatments are providing ongoing data regarding their effectiveness for these comorbidities among bipolar youth. Copyright © 2014 Elsevier B.V. All rights reserved.

    ABSTRACT: Studies have suggested an association between temperament characteristics and adjustment and psychiatric disorders, describing them as different manifestations of vulnerability to psychopathology. The objective of this study was to conduct an integrative review of the literature on temperament traits typical of bipolar patients in relation to the general population. A systematic search was conducted on the MEDLINE, PsycINFO and LILACS databases, using the headings bipolar disorder, temperament and/or personality, between January 2000 and December 2010. The search was performed in January 2011. A total of 199 articles were identified for potential inclusion in the review. After application of the exclusion criteria, a total of 15 articles were selected and their full texts analyzed. Review of the selected studies revealed heterogeneity in terms of sample profile and specific temperament traits assessed with the appropriate instruments. Temperament traits in bipolar patients are identified based on different theoretical models. The results of five studies consistently showed that neuroticism is a distinct personality trait in the temperament profile of bipolar patients. Future reviews should use more specific keywords and limit the search to studies with a longitudinal design.

    ABSTRACT: Previous research has shown that families with a parent who has bipolar disorder (BD) may experience family functioning difficulties. However, the association between family functioning and psychopathology among offspring of parents with BD, and offspring characteristics that may moderate this association, remains poorly understood. This study examined the cross-sectional associations between family functioning (cohesion, expressiveness, and conflict) and psychopathology in 117 offspring (ages 5-18) of 75 parents with BD. We also examined whether age and sex differences moderated these associations. We measured offspring psychopathology by examining current dimensional symptoms and DSM-IV emotional and behavioral disorders. Correlational analyses indicated that higher family conflict and lower cohesion were associated with higher internalizing and externalizing symptoms in offspring. Lower family cohesion was also associated with current offspring mood disorders. Moderation analyses indicated, first, that the link between lower family cohesion and internalizing symptoms was stronger for younger offspring compared to older offspring. Second, higher family conflict and current mood disorder were associated in younger males but not in older males or in females. Results remained the same after controlling for parental anxiety or substance use disorder comorbidity. Our study highlights the importance of accounting for family functioning when working with offspring at risk for BD, while also recognizing that the connections between family functioning and offspring outcomes are complex and differ based on offspring sex and developmental stage.
