A controlled social skills training for children with fetal alcohol spectrum disorders

Children with fetal alcohol spectrum disorders (FASD) have significant social skills deficits. The efficacy of a child friendship training (CFT) versus a delayed treatment control (DTC) was assessed for 100 children ages 6 to 12 years with FASD. Children in the CFT showed clear evidence of improvement in their knowledge of appropriate social behavior, and according to parent report, CFT resulted in improved social skills and fewer problem behaviors compared with DTC. Gains were maintained at 3-month follow-up. After receiving treatment, the DTC group exhibited similar improvement. Teachers did not report improvement as a function of social skills treatment. The findings suggest that children with FASD benefit from CFT but that these social skills gains may not be observed in the classroom.

Mapping White Matter Integrity and Neurobehavioral Correlates in Children with Fetal Alcohol Spectrum Disorders

Brain structural abnormalities and neurocognitive dysfunction have been observed in individuals with fetal alcohol spectrum disorders (FASDs). Little is known about how white matter integrity is related to these functional and morphological deficits. We used a combination of diffusion tensor and T1-weighted magnetic resonance imaging to evaluate white matter integrity in individuals with FASDs and related these findings to neurocognitive deficits. Seventeen children and adolescents with FASDs were compared with 19 typically developing age-and gender-matched controls. Lower fractional anisotropy (FA) was observed in individuals with FASDs relative to controls in the right lateral temporal lobe and bilaterally in the lateral aspects of the splenium of the corpus callosum. White matter density was also lower in some, but not all regions in which FA was lower. FA abnormalities were confirmed to be in areas of white matter in post hoc region of interest analyses, further supporting that less myelin or disorganized fiber tracts are associated with heavy prenatal alcohol exposure. Significant correlations between performance on a test of visuomotor integration and FA in bilateral splenium, but not temporal regions were observed within the FASD group. Correlations between the visuomotor task and FA within the splenium were not significant within the control group, and were not significant for measures of reading ability. This suggests that this region of white matter is particularly susceptible to damage from prenatal alcohol exposure and that disruption of splenial fibers in this group is associated with poorer visuomotor integration.

Brief Intervention for Alcohol Use by Pregnant Women

OBJECTIVES We examined the efficacy of brief intervention as a technique to help pregnant women achieve abstinence from alcohol. A second aim was to assess newborn outcomes as a function of brief intervention. METHODS Two hundred fifty-five pregnant women who were participants in the Public Health Foundation Enterprises Management Solutions Special Supplemental Nutrition Program for Women, Infants, and Children and who reported drinking alcohol were assigned to an assessment-only or a brief intervention condition and followed to their third trimester of pregnancy. Brief intervention consisted of 10- to 15-minute sessions of counseling by a nutritionist, who used a scripted manual to guide the intervention. Newborn outcomes of gestation, birth-weight, birth length, and viability were assessed. RESULTS Women in the brief intervention condition were 5 times more likely to report abstinence after intervention compared with women in the assessment-only condition. Newborns whose mothers received brief intervention had higher birthweights and birth lengths, and fetal mortality rates were 3 times lower (0.9%) compared with newborns in the assessment-only (2.9%) condition. CONCLUSIONS The success of brief intervention conducted in a community setting by nonmedical professionals has significant implications for national public health policies.

Psychiatric conditions associated with prenatal alcohol exposure

Since the identification of fetal alcohol syndrome (FAS) over 35 years ago, mounting evidence about the impact of maternal alcohol consumption during pregnancy has prompted increased attention to the link between prenatal alcohol exposure (PAE) and a constellation of developmental disabilities that are characterized by physical, cognitive, and behavioral impairments. These disabilities include a continuum of developmental disorders known as fetal alcohol spectrum disorders (FASDs). Longitudinal studies suggest that individuals with FASDs are at a greatly increased risk for adverse long-term outcomes, including mental health problems and poor social adjustment. This review summarizes the existing literature on mental health outcomes for individuals with PAE across the lifespan, including findings in infancy and early childhood, middle childhood, and adolescence and early adulthood. Research on the psychiatric disabilities suffered by individuals with FASDs throughout development highlights the need for training of mental health professionals in the identification and the provision of specific treatments to address the unique features of this developmental disability since early identification and treatment have been demonstrated to be protective against more serious secondary disabilities. It is hoped that with greater awareness of the mental health problems experienced by individuals with FASDs, these individuals can receive appropriate and early treatment resulting in more adaptive and rewarding lives.

Executive functioning predicts social skills following prenatal alcohol exposure.

Adverse sequelae of prenatal alcohol exposure include executive function and social skills impairments, although these two domains have not been empirically linked in alcohol-exposed individuals. This study investigated this relationship using the BRIEF and the SSRS in 98 children aged 6 to 11 years. Executive functions explained a significant percentage of variance in parent and teacher rated social skills. No differences were found among children with diagnoses of FAS, partial FAS, or alcohol-related neurodevelopmental disorder. It may be helpful to consider executive functioning in designing social skills interventions for alcohol-exposed children whether or not they have full FAS.

A longitudinal study of the long-term consequences of drinking during pregnancy: heavy in utero alcohol exposure disrupts the normal processes of brain development

Exposure to alcohol in utero can cause birth defects, including face and brain abnormalities, and is the most common preventable cause of intellectual disabilities. Here we use structural magnetic resonance imaging to measure cortical volume change longitudinally in a cohort of human children and youth with prenatal alcohol exposure (PAE) and a group of unexposed control subjects, demonstrating that the normal processes of brain maturation are disrupted in individuals whose mothers drank heavily during pregnancy. Trajectories of cortical volume change within children and youth with PAE differed from those of unexposed control subjects in posterior brain regions, particularly in the parietal cortex. In these areas, control children appear to show a particularly plastic cortex with a prolonged pattern of cortical volume increases followed by equally vigorous volume loss during adolescence, while the alcohol-exposed participants showed primarily volume loss, demonstrating decreased plasticity. Furthermore, smaller volume changes between scans were associated with lower intelligence and worse facial morphology in both groups, and were related to the amount of PAE during each trimester of pregnancy in the exposed group. This demonstrates that measures of IQ and facial dysmorphology predict, to some degree, the structural brain development that occurs in subsequent years. These results are encouraging in that interventions aimed at altering “experience” over time may improve brain trajectories in individuals with heavy PAE and possibly other neurodevelopmental disorders.

Abnormal Cortical Thickness Alterations in Fetal Alcohol Spectrum Disorders and Their Relationships with Facial Dysmorphology

Accumulating evidence from structural brain imaging studies on individuals with fetal alcohol spectrum disorder (FASD) has supported links between prenatal alcohol exposure and brain morphological deficits. Although global and regional volumetric reductions appear relatively robust, the effects of alcohol exposure on cortical thickness and relationships with facial dysmorphology are not yet known. The structural magnetic resonance imaging data from 69 children and adolescents with FASD and 58 nonexposed controls collected from 3 sites were examined using FreeSurfer to detect cortical thickness changes across the entire brain in FASD and their associations with facial dysmorphology. Controlling for brain size, subjects with FASD showed significantly thicker cortices than controls in several frontal, temporal, and parietal regions. Analyses conducted within site further revealed prominent group differences in left inferior frontal cortex within all 3 sites. In addition, increased inferior frontal thickness was significantly correlated with reduced palpebral fissure length. Consistent with previous reports, findings of this study are supportive of regional increases in cortical thickness serving as a biomarker for disrupted brain development in FASD. Furthermore, the significant associations between thickness and dysmorphic measures suggest that the severity of brain anomalies may be reflected by that of the face.

Predictors of Stress in Parents of Children with Fetal Alcohol Spectrum Disorders

ABSTRACT This study examined child characteristics and family factors as predictors of stress in the biological or adoptive parents of 6- to 12-year-old children with fetal alcohol spectrum disorders (FASDs). Impaired executive functioning, poorer adaptive functioning, externalizing and internalizing behavior problems, and adoptive parent status all made significant and independent contributions to the prediction of higher levels of child domain stress, as reported by parents on the Parenting Stress Index. Biological parent status and fewer family resources were associated with higher levels of parent domain stress. Teacher ratings of the childs executive functioning impairments and externalizing and internalizing behavior problems also were associated with parent reports of child domain stress. Findings highlight the need to provide support not only to children with FASDs, but to their caregivers as well.

Intervention for Individuals with Fetal Alcohol Spectrum Disorders: Treatment Approaches and Case Management.

Exposure to alcohol in utero is considered to be the leading cause of developmental disabilities of known etiology. The most severe consequence of such exposure, fetal alcohol syndrome (FAS), is characterized by a distinct constellation of characteristic facial anomalies, growth retardation, and central nervous system (CNS) dysfunction. Some individuals with prenatal alcohol exposure (PAE) do not meet the full criteria for FAS, but instead are diagnosed with partial FAS, alcohol related neurodevelopmental disorder (ARND), or alcohol related birth defects (ARBD). The entire continuum of effects from PAE is increasingly being referred to under the umbrella term of fetal alcohol spectrum disorders (FASDs). An extensive body of research has documented major cognitive, behavioral, adaptive, social, and emotional impairments among individuals with FASDs. Although FAS was identified in the U.S. over 35 years ago, the development, evaluation, and dissemination of evidence-based interventions for individuals with FASDs have lagged behind significantly. Encouragingly, however, in recent years there has been a marked increase in efforts to design and test interventions to remediate the impairments associated with prenatal alcohol exposure. This article will review treatment needs and considerations for individuals with FASDs and their families, current empirically tested treatment approaches, case management issues, and suggestions for future directions in research on the treatment of FASDs.

Outcomes of home visits for pregnant mothers and their infants: a cluster randomized controlled trial.

Objective:To evaluate the effect of home visits by community health workers (CHWs) on maternal and infant well being from pregnancy through the first 6 months of life for women living with HIV (WLH) and all neighborhood mothers. Design and methods:In a cluster randomized controlled trial in Cape Town townships, neighborhoods were randomized within matched pairs to either standard care, comprehensive healthcare at clinics (n = 12 neighborhoods; n = 169 WLH; n = 594 total mothers); or Philani Intervention Program, home visits by CHWs in addition to standard care (PIP; n = 12 neighborhoods; n = 185 WLH; n = 644 total mothers). Participants were assessed during pregnancy (2% refusal) and reassessed at 1 week (92%) and 6 months (88%) postbirth. We analyzed PIPs effect on 28 measures of maternal and infant well being among WLH and among all mothers using random effects regression models. For each group, PIPs overall effectiveness was evaluated using a binomial test for correlated outcomes. Results:Significant overall benefits were found in PIP compared to standard care among WLH and among all participants. Secondarily, compared to standard care, PIP WLH were more likely to complete tasks to prevent vertical transmission, use one feeding method for 6 months, avoid birth-related medical complications, and have infants with healthy height-for-age measurements. Among all mothers, compared to standard care, PIP mothers were more likely to use condoms consistently, breastfeed exclusively for 6 months, and have infants with healthy height-for-age measurements. Conclusion:PIP is a model for countries facing significant reductions in HIV funding whose families face multiple health risks.
