Prenatal alcohol exposure: An assessment strategy for the legal context.

Studies over the last two decades have shown that people with fetal alcohol spectrum disorders (FASD) have the kind of brain damage that increases risk of criminal behavior. Thus, it is generally accepted that FASD is likely to affect a sizable minority of individuals involved in the justice system. Most of these defendants have never been diagnosed because they lack the facial abnormalities and severe intellectual deficiency that would have improved identification and diagnosis in childhood.

Implementation of a shared data repository and common data dictionary for fetal alcohol spectrum disorders research.

Many previous attempts by fetal alcohol spectrum disorders researchers to compare data across multiple prospective and retrospective human studies have failed because of both structural differences in the collected data and difficulty in coming to agreement on the precise meaning of the terminology used to describe the collected data. Although some groups of researchers have an established track record of successfully integrating data, attempts to integrate data more broadly among different groups of researchers have generally faltered. Lack of tools to help researchers share and integrate data has also hampered data analysis.

Alcohol use before and during pregnancy in western Washington, 1989-2004: implications for the prevention of fetal alcohol spectrum disorders.

Objective: We examined trends in rates of self-reported pregnancy alcohol use among women in western Washington.

Study Design: Between 1989 and 2004, we conducted 3 studies in western Washington State on problems that are associated with maternal prenatal alcohol or drug abuse (n = 12,526). To determine study eligibility, we screened hospitalized postpartum women for alcohol and drug use in the month before and during pregnancy.

Many infants prenatally exposed to high levels of alcohol show one particular anomaly of the corpus callosum.

Introduction: Effects of prenatal alcohol exposure on the brain are seen at every age. The earlier they can be quantified, the better the prognosis for the affected child. Here we show measurable alcohol effects at birth on a structure currently used for nosology only much later in life.

Three-year developmental outcomes in children with prenatal alcohol and drug exposure.

Purpose: The purpose of this study was to describe the performance of children whose mothers abused alcohol and drugs heavily during pregnancy, using the Bayley Scales of Infant Development Second Edition (BSID-II) at three years, and to examine the effects of study group, prenatal binge alcohol exposure, and prematurity on developmental outcome.

Methods: Children were born to mothers recruited from two large hospitals or through community referral. Hospital recruits were randomly assigned to either a three-year paraprofessional home visitation intervention program (n = 30) or a control group (n = 31).

Damage to the human cerebellum from prenatal alcohol exposure: the anatomy of a simple biometrical explanation.

Since 1973, it has become clear that exposure of otherwise normal human fetuses to high levels of alcohol damages a substantial number of the exposed brains in a wide variety of ways nowadays referred to collectively as the fetal alcohol spectrum disorders (FASDs). Averages of images and measurements of brains with these disorders are quantitatively different from normal, and the cerebellum is one of the structures at which differences are typically noted. The present article extends these techniques to a simple, practical, and enlightening detection rule for fetal alcohol damage in adolescents and adults known to have been heavily exposed.

Binge drinking during pregnancy as a predictor of psychiatric disorders on the Structured Clinical Interview for DSM-IV in young adult offspring.

Objective: This study explored the extent to which the high frequency of psychiatric problems reported in clinical groups with fetal alcohol spectrum disorders might also be observed in a nonclinical group of young adults and the psychiatric conditions that are related to prenatal alcohol exposure in this group.

Method: From a longitudinal prospective study beginning with interviews of 1,529 pregnant women, a birth cohort of about 500 newborns was chosen to include all of the most heavily alcohol exposed plus a sampling of the continuum of alcohol exposures from total abstinence through heavy drinking. At an average age of 25.

Preliminary evidence that prenatal alcohol damage may be visible in averaged ultrasound images of the neonatal human corpus callosum.

Brain damage consequent to prenatal alcohol exposure can be detected by measurements of the corpus callosum in the midline magnetic resonance (MR) brain image in adolescents and adults. The present article extends this finding into the neonatal period, when the power of detection to ameliorate the quality of the child's future life is greatest. The midline corpus callosum of the very young infant can be located reliably in multiple frames of clinical transfontanelle ultrasound.

Preventing alcohol and drug exposed births in Washington state: intervention findings from three parent-child assistance program sites.

Home visitation interventions show promise for helping at-risk mothers, yet few programs have been developed and evaluated specifically for alcohol and drug-abusing pregnant women. This study examines outcomes among 216 women enrolled in the Washington State Parent-Child Assistance Program, a three-year intervention program for women who abuse alcohol and drugs during an index pregnancy. Pretest-posttest comparison was made across three sites: the original demonstration (1991-1995), and the Seattle and Tacoma replications (1996-2003).

Effects of prenatal alcohol exposure on fine motor coordination and balance: A study of two adult samples.

Motor coordination was assessed in two samples of adult subjects: one sample (n = 90) included adults previously diagnosed with one of a number of Fetal Alcohol Spectrum Disorders (FASD) and comparison peers, the second was a prospective longitudinal study of adults who were exposed to varying levels of alcohol as fetuses (n = 402). This comparative analysis sought to determine whether motor effects seen in both clinical and nonclinical children persist into adulthood, whether any individual motor tasks show significant effects of prenatal alcohol exposure across the age range, and whether motor assessments of adults have any role in diagnostic strategies for adults suspected of FASD. Motor tests included balance and unilateral, bilateral, finger, hand and foot coordination.

A pilot community intervention for young women with fetal alcohol spectrum disorders.

Fetal Alcohol Syndrome, a permanent birth defect caused by maternal alcohol use during pregnancy, is a leading preventable cause of mental retardation. Neuropsychological deficits have been well documented, however interventions developed have not been evaluated. We describe a successful 12-month community pilot intervention with 19 young women with Fetal Alcohol Spectrum Disorders (FASD).

Risk factors for adverse life outcomes in fetal alcohol syndrome and fetal alcohol effects.

Clinical descriptions of patients with Fetal Alcohol Syndrome (FAS) and Fetal Alcohol Effects (FAE) suggest major problems with adaptive behavior. Five operationally defined adverse outcomes and 18 associated risk/protective factors were examined using a Life History Interview with knowledgeable informants of 415 patients with FAS or FAE (median age 14 years, range 6-51; median IQ 86, range 29-126). Eighty percent of these patients were not raised by their biological mothers.

A 21-year longitudinal analysis of the effects of prenatal alcohol exposure on young adult drinking.

Background: Prenatal alcohol exposure may be a risk factor for the development of alcohol problems in humans.

Methods: We use data beginning with interviews of women in prenatal care at midpregnancy to predict alcohol use and alcohol-related problems in their offspring now aged 21 years. Maternal drinking during pregnancy was assessed from November 4, 1974, through October 2, 1975, along with measures of maternal smoking, use of caffeine and other drugs, and demographic factors.

Midline corpus callosum is a neuroanatomical focus of fetal alcohol damage.

Prenatal exposure to high levels of alcohol often induces birth defects that combine morphological stigmata with neurological or neuropsychological deficits. But it has proved problematic to diagnose these syndromes in adolescents and adults, in whom the morphological signs are absent or attenuated, the behavioral deficits nonspecific, and the exposure history often difficult to reconstruct. Localizing the associated brain abnormalities might circumvent most of these difficulties.

Corpus callosum shape and neuropsychological deficits in adult males with heavy fetal alcohol exposure.

Persons with brain damage consequent to prenatal alcohol exposure have typically been diagnosed with either fetal alcohol syndrome (FAS) or fetal alcohol effects (FAE), depending on facial features. There is great variability of behavioral deficits within these groups. We sought to combine neuroanatomical measures with neurocognitive and neuromotor measures in criteria of greater sensitivity over the variety of consequences of alcohol exposure.

Geometric morphometrics of corpus callosum and subcortical structures in the fetal-alcohol-affected brain.

Background: Although experienced clinicians have been diagnosing fetal alcohol syndrome (FAS) for nearly 30 years, the rest of the spectrum of fetal alcohol damage is not being classified effectively. This article describes a quantification of neuroanatomical structure that may supply a useful discriminator of prenatal brain damage from alcohol. It is demonstrated in a data set of adults of both sexes.

Direct and indirect effects of prenatal alcohol damage on executive function.

Patients with Fetal Alcohol Syndrome (FAS) and Fetal Alcohol Effects (FAE) often have difficulty functioning appropriately in everyday life and seem to employ poor problem-solving strategies. Tests of executive function are relevant for quantifying the functional deficits and underlying real-life problems associated with prenatal alcohol exposure. This study considers two pathways for the effects of prenatal alcohol on executive function: a direct effect and an indirect effect through prenatal alcohol's effect on IQ.

Neuropsychiatric implications and long-term consequences of fetal alcohol spectrum disorders.

Prenatal alcohol exposure can cause a whole spectrum of central nervous system (CNS) sequelae that persist throughout the life span and manifest in a spectrum of effects from clinically indistinguishable to severely impairing. The greatest impact of alcohol as a teratogen is to the brain-the greatest need is for holistic treatment and management of the associated mental disorders. The interaction of this subtle brain damage with the complex psychosocial circumstances surrounding the birth of a child to a mother with alcohol problems can further compound development and result in costly and devastating social consequences.

Identifying maternal self-reported alcohol use associated with fetal alcohol spectrum disorders.

Background: The incidence of Fetal Alcohol Syndrome (FAS) has been estimated at 1 to 3 per 1,000 live births. Fetal Alcohol Spectrum Disorders (FASD) (which include FAS) are estimated to occur in about 1 in 100 births. Cessation of drinking during pregnancy can improve the outcome even if the unborn child is already affected.

On categorizations in analyses of alcohol teratogenesis.

In biomedical scientific investigations, expositions of findings are conceptually simplest when they comprise comparisons of discrete groups of individuals or involve discrete features or characteristics of individuals. But the descriptive benefits of categorization become outweighed by their limitations in studies involving dose-response relationships, as in many teratogenic and environmental exposure studies. This article addresses a pair of categorization issues concerning the effects of prenatal alcohol exposure that have important public health consequences: the labeling of individuals as fetal alcohol syndrome (FAS) versus fetal alcohol effects (FAE) or alcohol-related neurodevelopmental disorder (ARND), and the categorization of prenatal exposure dose by thresholds.

Effects of prenatal alcohol exposure on social behavior in humans and other species.

Alcohol exposure during development causes central nervous system alterations in both humans and animals. Although the most common behavioral manifestation of these alterations is a reduction in cognitive abilities, it is becoming increasingly apparent that deficits in social behavior may be very prevalent sequelae of developmental alcohol exposure. In infancy and early childhood, deficits in attachment behavior and state regulation are seen in both alcohol-exposed people and animals, suggesting that these changes are largely the result of the alcohol exposure rather than maternal behavior.

Prenatal cocaine and neuromotor outcome at four months: effect of duration of exposure.

The effect of prenatal cocaine exposure on the motor development of full-term infants was examined in a prospective study, controlling for maternal characteristics and exposure to other substances. Intrauterine cocaine exposure was determined at birth by maternal self-report and was verified by hair analysis. At 4 months, 120 cocaine-exposed (COC) and 186 non-cocaine-exposed (NON-COC) infants were assessed by blinded examiners using a standard evaluation of neuromotor function, the Movement Assessment of Infants (MAI).

Individual differences in auditory and visual attention among fetal alcohol-affected adults.

Background: Deficits in attention are commonly identified among patients who have been prenatally exposed to alcohol, and they often affect the ability of the patients to function appropriately in society.

Methods: Eleven adult patients with fetal alcohol syndrome (FAS) or fetal alcohol effects (FAE) were compared with nine adult subjects with no history of prenatal alcohol exposure, using four tests of visually and auditorially mediated attention.

Results: In relation to the comparison group, patients with FAS/FAE exhibited substantial deficits in both auditory and visual attention; the auditory deficits were greater.

Neuropsychological deficits in adolescents with fetal alcohol syndrome: clinical findings.

Understanding the nature of cognitive deficits among adolescent patients with fetal alcohol syndrome (FAS) can direct future research on assessment and intervention. In an exploratory study, nine nonretarded teenagers with FAS were administered tests of IQ and adaptive behavior, and neuropsychological tests presumed sensitive to alcohol effects. Their performance was compared with psychometric norms and to data from a sample of 174 adolescents with minimal or no prenatal alcohol exposure.

Prenatal alcohol exposure and family history of alcoholism in the etiology of adolescent alcohol problems.

Objective: To examine the relative importance of prenatal alcohol exposure and family history of alcoholism for the prediction of adolescent alcohol problems.

Method: In 1974-75, a population-based, longitudinal prospective study of alcohol and pregnancy began with self-report of alcohol use by pregnant women. In a 14-year follow-up, 439 parents provided information on the family history of alcohol problems for these adolescent offspring.
