One-Year Developmental Outcomes for Infants of Mothers With Bipolar Disorder.

ABSTRACT: OBJECTIVE:Few data about the development of infants born to women with bipolar disorder have been published. We hypothesized that infants of women with bipolar disorder (by DSM-IV criteria) treated with psychotropics (BD+) or untreated with psychotropics (BD-) would demonstrate poorer cognitive and behavioral development than infants of controls. On the basis of previous studies, we expected that psychotropic-exposed infants of women in the BD+ group would have poorer neuromotor performance during infancy. METHODS:This longitudinal study included 197 mother-infant dyads recruited to participate between July 2006 and March 2011: 81 with prenatal maternal bipolar disorder without psychotropic treatment (BD-, n = 27) or bipolar disorder with psychotropic exposure (BD+, n = 54) and 116 in which infants were exposed to neither bipolar disorder nor psychotropics. Maternal psychopathology and pharmacotherapy exposure assessments were completed at 20, 30, and 36 prenatal weeks and 12, 26, and 52 weeks postpartum. Infants were evaluated with the Bayley Scales of Infant Development, Second Edition, which included the psychomotor (Psychomotor Development Index [PDI]), cognitive (Mental Development Index [MDI]), and behavioral (Behavioral Rating Scale [BRS]) components. RESULTS:Neither prenatal exposure to BD- or BD+ significantly impacted overall PDI (P = .2449), MDI (P = .7886), or BRS (P = .6072) scores. However, we observed a significant effect of BD+ exposure-by-time interaction for the BRS Motor Quality index (F??? = 3.16, P = .0441), with BD+ exposed infants less likely to be above the 75th percentile at the 52-week assessment (mean = 11.5%) compared with BD- (mean = 40.0%) and nonexposed infants (mean = 48.4%). CONCLUSIONS:We found no significant impact of prenatal BD- or BD+ exposure on infant PDI, MDI, or overall BRS scores at 12, 26, or 52 weeks of age, with most scores remaining within normal limits. Consistent with previous studies, we found a specific effect of prenatal BD+ exposure on quality of motor functioning at 1 year. However, the majority of infants were within normal limits on this developmental outcome. TRIAL REGISTRATION:ClinicalTrials.gov identifier: NCT00585702.

Project description:ImportanceBipolar disorder (BD) is a debilitating mental illness associated with high costs to diagnosed individuals and society. Within the past 2 decades, increasing numbers of children and adolescents have been diagnosed as having BD. While functional magnetic resonance imaging (fMRI) studies have begun to investigate the neural mechanisms underlying BD, few have directly compared differences in youths with BD and adults with BD (hereafter BD-youths and BD-adults, respectively).ObjectiveTo test the hypothesis that BD-youths (<18 years old) would show greater convergence of amygdala hyperactivation and prefrontal cortical hypoactivation vs BD-adults.Data sourcesPubMed and PsycINFO databases were searched on July 17, 2013, for original, task-related coordinate-based fMRI articles.Study selectionIn total, 21 pediatric studies, 73 adult studies, and 2 studies containing distinct pediatric and adult groups within the same study met inclusion criteria for our ALE analyses.Data extraction and synthesisCoordinates of significant between-group differences were extracted from each published study. Recent improvements in GingerALE software were used to perform direct comparisons of pediatric and adult fMRI findings. We conducted activation likelihood estimation (ALE) meta-analyses directly comparing the voxelwise convergence of fMRI findings in BD-youths vs BD-adults, both relative to healthy control (HC) participants.ResultsAnalyses of emotional face recognition fMRI studies showed significantly greater convergence of amygdala hyperactivation among BD-youths than BD-adults. More broadly, analyses of fMRI studies using emotional stimuli showed significantly greater convergence of hyperactivation among BD-youths than BD-adults in the inferior frontal gyrus and precuneus. In contrast, analyses of fMRI studies using nonemotional cognitive tasks and analyses aggregating emotional and nonemotional tasks showed significantly greater convergence of hypoactivation among BD-youths than BD-adults in the anterior cingulate cortex.Conclusions and relevanceOur data suggest that amygdala, prefrontal, and visual system hyperactivation is important in the emotional dysfunction present in BD-youths, as well as that anterior cingulate cortex hypoactivation is relevant to the cognitive deficits in BD-youths. Future studies are required to determine if the developmental fMRI differences between BD-youths and BD-adults identified by our ALE meta-analyses are useful as brain-based diagnostic or treatment markers of BD, including either longitudinal neuroimaging studies of BD-youths as they become adults or cross-sectional imaging studies directly comparing BD-youths with BD-adults.
