Fetal Alcohol Spectrum Disorders
binäre optionen mit etoro In 1973, researchers began to recognize the harmful effects alcohol had on a developing fetus. Jones and colleagues, of the University of Washington–Seattle, published a report in the Lancet describing both the dysmorphic and developmental effects alcohol had on eight children born to women affected by alcoholism. A later report by Jones and Smith first coined the term “fetal alcohol syndrome” (FAS).

The Seattle 500 Study, an active 30-year research project headed by Dr. Ann Streissguth, examined the full spectrum of effects of alcohol on developing fetuses, specifically targeting the relationship between drinking levels and neurodevelopment.3 However, it was the result of animal research that solidified the relationship between alcohol and dysmorphic and developmental effects on fetuses. As many were skeptical of alcohol’s effects given the substance’s long history of use and the medical field’s late recognition, scientists were able to perform controlled tests to pinpoint whether or not alcohol was the cause.3 The studies of alcohol on pregnant rats, mice, and dogs all produced similar fetus effects as the substance did with humans. Alcohol did, in fact, have harmful effects on a developing fetus.

Tastylia, Tadalafil Oral Strip There are three diagnostic criteria for FAS: facial dysmorphology, pre- and postnatal growth deficiencies, and central nervous system dysfunction.3 However, FAS can produce a wide spectrum of effects, some more apparent than others; therefore, within FAS, the Institute of Medicine describes a number of diagnoses under the term fetal alcohol spectrum disorders (FASD), including partial FAS, fetal alcohol effects, alcohol-related birth defects, and alcohol-related neurodevelopmental disorders.3 Dose, pattern, and timing of alcohol exposure all influence the harmful effects to the fetus, and because the effects vary widely, no amount of alcohol is safe for consumption while pregnant.3 Factors such as prenatal care, nutrition, and genetics all influence the effect the alcohol will have on the fetus.

Behaviorally, alcohol has been linked to impaired intelligence and reflex development, motor coordination deficits, and hyperactivity.3 Kodituwakku found that deficits in learning, memory, and attention, as well as the inability to regulate emotions are also caused by FASDs. Fetal alcohol spectrum disorders may also contribute to psychiatric disorders and addiction vulnerability.3
opcje binarne ropa Identifying those with prenatal alcohol exposure is difficult, as some individuals with FASDs do not fully meet the classifying factors. Therefore, the NIAAA is currently funding research to develop effective methods of diagnosing individuals so correct treatment may be provided.3 Scientists are exploring three-dimensional camera imaging for the detection of facial deformations, and trying to link the deformations with certain brain functions in order to identify a “unique signature” of FASDs.3 Current methods of diagnosis include questionnaire screenings of the mother, as better identifying women who drink during pregnancy will aid in the diagnosis of FASDs. The TACE, TWEAK, AUDIT, and AUDIT-C are all used to screen for alcohol use.

FAEEs can detect alcohol use within the last few weeks of pregnancy.

Therefore, the Institute of Medicine has created a three-level model for prevention. One level targets the general population, a second targets high-risk communities, and a third targets specific individuals.3 It has been found that targeting the general population is not an effective approach; however, targeting high-risk communities and specific individuals has shown success. For high-risk communities, screening has shown to be successful in recognizing and intervening with risky drinking habits; however, it is not always utilized so scientists have begun researching methods of reducing the severity of FASD effects, such as vitamin use.3 In animal studies, vitamins C and E have shown to reduce the potential effects. Scientists are also looking at serotonin agonists and nutrients such as choline, folate, zinc, and nicotinamide.3
