Children prenatally expos to alcohol may exhibit a number of developmental deficits.

Children prenatally expos to alcohol may exhibit a number of developmental deficits. The period of times applied to these children vary depending in succession the severity of the deficits; they include fetal alcohol syndrome fetal alcohol results alcohol-related birth defects, and alcohol-related neurodevelopmental disorder. Dr Joseph L Jacobson and Sandra W Jacobson review these conditions and ready research findings on the cognitive and behavioral powers of prenatal exposure to alcohol, which include hyperactivity and riddles with attention, learning, memory, and social and emotional unravelling (pp. 282-286)

Maternal alcohol use during pregnancy contributes to a range of drifts in exposed children, including hyperactivity and attention question s learning and memory deficits, and question s with social and emotional development

Fetal Alcohol Syndrome

The mostly serious consequence of maternal drinking during pregnancy is fetal alcohol syndrome (FAS). FAS was first described in the United States by the agency of Jones and Smith (1973), who identified a distinctive wager of facial anomalies--short eyelid openings (palpebral fissures), flat midface, thin upper lip, and a flat or plane groove between nose and upper lip (philtrum)--in children whose mothers drank to a high degree heavily during pregnancy. These children also exhibit shooting retardation as well as significant cognitive and/or behavioral problems

In contrast with Down syndrome patients, who exhibit impairment in virtually all aspects of intellectual function, FAS patients repeatedly perform relatively well on language trials (e.g., Kodituwakku et al. 1995) although they protect to have difficulty with complexus language tests, especially those tapping the pragmatic aspect of language. The mostly consistent deficits are in arithmetic (Streissguth et al. 1991; Clarren et al. 1994) and attentional function (Kodituwakku et al. 1995) Although many FAS patients are mentally retarded (i.e., have an IQ les than 70) a substantial proportion perform in the gentle average to average range in succession IQ tests (Streissguth et al. 1991)

It is particularly instructive to consider studies comparing children with FAS with children not expos to alcohol who have similar soft IQ scores. In one similar study, FAS children had reading scores similar to those of IQ-matched manage subjects, but they performed significantly les well upon arithmetic and certain aspects of attention (eg executive function, which is the ability to coordinate, plan, and do appropriate responses and to modify behavior flexibly in answer to feedback) (Carmichael Olson et al. 1998) Children with FAS have poorer socioemotional disclosure (i.e., emotional, personality, social, and moral development) than would be look forward toed based on their IQ scores (Thomas et al. 1998; Carmichael Olson et al. 1998)

Fetal Alcohol imports and Alcohol-Related Neurodevelopmental Disorder

The limit "fetal alcohol effects" (FAE) is applied to children whose mothers are known to have soaked heavily during pregnancy and who exhibit an but not all, of the characteristics of FAS (Streissguth et al. 1991; cabbages et al. 1997). The IQ scores of FAE patients are also saddened but tend to be somewhat higher than those set up in FAS children.

In an attempt to increase precision in diagnosis, an Institute of Medicine panel has approveed distinguishing among three forms of FAE (Stratton et al. 1996) The expression "partial FAS" applies to children with confirmed heavy prenatal alcohol frontage some components of the characteristic alcohol-related facial dysmorphology, and physical produce or neurodevelopmental abnormalities. "Alcohol-related birth defects" (ARBD) is applied to those with confirmed heavy prenatal alcohol exposing and one or more congenital abnormalities, usually cardiac, skeletal, renal, ocular, or auditory.

"Alcohol-related neurodevelopmental disorder" (ARND) is applied to children with confirmed heavy. prenatal alcohol outlook who exhibit measurable, albeit generally subtler neurobehavioral deficits than are seen with FAS. Although reduc IQ scores are not usually raise (Goldschmidt et al. 1996; Jacobson et al. 1998a; if it be not that see Streissguth et al. 1990) ARND children exhibit developmental deficits in the domains that are greatest in number severely affected by FAS. That is, the principally consistent deficits are in arithmetic (Goldschmidt et al. 1996; Streissguth et al. 1993) attention (Streissguth et al. 1994; Jacobson et al. 1998a), and socioemotional function (Carmichael Olson et al. 1998; Jacobson et al. 1998b) In comparison with FAS, ARND affects a plenteous larger number of children, nevertheless the effects, although clinically important, are les inexorable Most recently, the term "feral alcohol image disorders" (FASD) has emerged to belong collectively to FAS, partial FAS, ARBD, and ARND.

The following sections examine in more detail the cognitive and behavioral forces of prenatal exposure to alcohol.

Hyperactivity and Attention

Data onward the relationship between FAS and hyperactivity are inconsistent. Although hyperactivity has been reported in several studies of clinic patients (Steinhausen et al. 1982; Nanson and Hiscock 1990) it was rated as least plain among the problems reported by way of parents of FAS children in a fresh study (Roebuck et al. 1999) cabbages and colleagues (1997) found little evidence of hyperactivity or impulsivity in a sample of FAS/FAE children recruited when their mothers sought prenatal care. These authors remind of that studies drawing participants from medical and psychiatric referrals, in contrast with longitudinal samples in the same state [i]or[/i] condition as their own, may be more likely to include patients living in unstable family situations. As a end the hyperactivity reported in studies of clinic-referred patients may have been caused by dint of social and environmental factors, as it is as co-occurring attachment disorders, anxiety, and post-traumatic stres disorder. Clinic-referred samples may also be affected by means of selection bias. For example, FAS children who are also hyperactive are more likely to be referr for treatment because their behavior is disruptive in family and indoctrinate settings.
