Explain The Timing Of Prenatal Exposure To The Teratogen

The science behind FAS is quite simple; as it is known that alcohol has a damaging effect on the body, it has similar consequences on the fetus. Since the fetus is constantly developing, the alcohol causes more serious defects to the unborn child. Alcohol exposure to a fetus is known as a teratogen. “Teratogens are substances or conditions that disrupt typical development in offspring as a result of gestational exposure and cause birth defects.” (Wilson & Fraser, 1977). Although the exposure to alcohol causes problems in the fetus, studies have shown that it may not accurately be the alcohol in the mother’s system that causes these defects, rather the byproducts that form when the body metabolizes the alcohol. This can lead to a decrease in brain cells, abnormal location of neurons, and gross malformation to the brain. Since alcohol causes this central nervous system damage, it is classified as a neurobehavioral teratogen, which is a group of teratogens that cause brain damage and modify behaviors. (Riley & Vorhees, 1986). The CNS damage is the primary defect due to alcohol and it is quite common to have these damages without any physical abnormalities. The more alcohol that is consumed the more birth defects that will arise in the

Fetal alcohol spectrum disorder (FASD) is a concise, uniform definition for conditions caused by prenatal alcohol exposure. FASD is a broad term used to describe the range of effects that can occur in an individual whose mother drank alcohol during pregnancy (Caley, Kramer, & Robinson, 2005). Fetal alcohol spectrum disorder can also cause growth retardation, birth defectscomma and deficits in cognitive, languagecomma and motor development (Coles et al., 2015). Fetal alcohol spectrum disorder is a teratogenic effect, which is caused by daily, chronic, heavy and frequent alcohol use while in utero. Chances of an infant diagnosed with FASD are 0.5 to 3 in 1,000 live births (Cone-Wesson, 2005). Fetal alcohol spectrum disorder has many different diagnoses. There is fetal alcohol syndrome (FAS), partial fetal alcohol syndrome (PFAS)comma and alcohol-related neuro-developmental disorder (ARND)comma all under the fetal alcohol spectrum disorder umbrella (Brown et al., 2015). Maternal alcohol use is correlated to the timing, frequencycomma and quantity of the consumption of alcohol during pregnancy. Drinking during the first trimester may not be as detrimental as drinking during the second or third trimester. The frequency of alcohol consumed is also a key factor in FASD, such as how often per day drinks are consumed, the quantity of alcohol consumed, and how many glasses or cans per day the mother consumes

The quality of life for these children is unfortunately not the best. They can have limb, facial, and organ defects, and will have stunted physical growth throughout young adult life. Prenatal exposure can also have a negative effect on motor skills, especially fine motor tasks such as writing and balancing. The disabilities depend on the mother and her drinking habits. The children of heavy drinkers while pregnant, have many more developmental problems than of those whose mother was a light drinker. The most common problems among these children with alcohol exposure are with balance, coordination, and how they are able to play and handle a ball.

The term “Fetal Alcohol Spectrum disorders” (FASDS) is used to describe the numerous problems associated with exposure to alcohol before birth. Each year in the United States, up to 40,000 babies are born with “Fetal Alcohol Spectrum disorders” (FASDs) (Substance Abuse and Mental Health Services Administration). Additionally, Fetal Alcohol Spectrum disorders (FASDs) comes with effects that range from mild to severe. These effects include mental retardation; learning, emotional and behavioral problems; and defects involving the heart, face and other organs. According to the U.S. Surgeon General, the patterns of drinking that place a baby at greatest risk for FASDS are binge drinking and drinking seven or more drinks per week (Surgeon General). However, FASDS can occur in babies of women who drink less. There is no way of measuring how much alcohol one can consume before defects occur, and no proof that small amounts of alcohol are safe. As little as one drink a day can cause a baby some degree of harm and interfere with their normal development.

As stated earlier, alcohol has its greatest effect on the developing embryo during the first trimester of pregnancy with its teratogenic effect causing mental retardation as well as characteristic craniofacial abnormalities that are characteristic of the disease. It has also been demonstrated with experimental animal models that there is a clear "dose-response" effect between the amount of alcohol consumed by the mother and the risk that is associated with developing FAS symptoms (Walpole, p. 875). It has been proposed by Walpole and associates that there are various degrees to which the fetus An be effected. Walpole uses the term "fetal alcohol syndrome" to refer to serious effects due to heavy maternal drinking and "fetal alcohol effect" to refer to those effects thought to occur with lower maternal alcohol intake (Walpole, p. 875). Regardless of the degree to which

Fetal Alcohol Syndrome (FAS) is a disorder that occurs when a mother consumes alcohol while pregnant. Individuals with FAS may face many problems such as, bad vision, hearing impairments, memory difficulty, communicative hurdles, and much more (Bergen & Yu, 2012). In began in 1981 when expecting mothers were advised not to drink while pregnant (Alcohol Policies Project, n.d). However, is 1995 4 times more mothers were consuming alcohol in comparison to a few years earlier in 1991 (Alcohol Policies Project, n.d). In addition, 52 percent of women ages 18-34 claimed to have been consuming alcohol while pregnant (Alcohol Policies Project, n.d). The reason for a mothers decision to drink is unknown, it could possibly be that mothers have read reports

Whenever a mother drinks, her baby is at risk for Fetal Alcohol Syndrome or Fetal Alcohol Effect. When a pregnant women drinks alcohol, her baby does too. It is not clear whether there is a threshold amount of alcohol that must be consumed before damage to the baby occurs. There is also no proof that small amounts of alcohol are safe.

Alcohol consumption during pregnancy can cause fetal alcohol syndrome. The severely effected victims of the syndrome have a variety of congenital defects: mental retardation, coordination problems, and heart, eye, and genitourinary malformations, as well as low birth weight and slowed growth rate. Most apparent are characteristic facial abnormalities.

Fetal alcohol spectrum disorder (FASD) is a general term consist disabilities when a mother consumes alcohol during her pregnancy. The medical prognosis of FASD includes: Fetal Alcohol Syndrome (FAS), Partial Fetal Alcohol Syndrome (PFAS), Alcohol Related Neurodevelopmental Disorder (ARND) and Alcohol Related Birth Defects (ARBD). Moreover, teratogen is a harmful agent that can interrupt the development of an embryo. For instance, alcohol is teratogen. As per Health Canada, FASD is a leading cause of a completely avertable developmental disability but it still affects approximately one percent of the Canadian population (Batshaw, Roizen & Lotrecchiano, 2012). However, there are many alterations to the disabilities and the development of sub-groups. Thereby, the term FASD is introduced to ensure the incidence of all the characteristics (mental, behavioral and physical) associated with prenatal exposure to alcohol. The exposure to alcohol during the pregnancy places the infant at the risk of developing problems such as abnormal appearance, low body weight, poor coordination, low intelligence, facial abnormalities, neuropsychological deficits, central nervous system deficits and growth delays (Riley, Infante & Warren, 2011). As the paper progress, we will discuss the characteristics, causes and the epidemiology of FASD. In addition we will all focus on the mental disorder such as Attention Deficit Hyperactivity Disorder (ADHD) associated with FASD and a

pregnancy. FAS is unique in that effects on the children are directly linked to maternal drinking

The results of drinking alcohol with a baby in the womb can be very serious. There are a range of effects that can occur to the child exposed. The most serious result of drinking during pregnancy is Fetal Alcohol Syndrome (FAS). Some of the effects of FAS are hyperactivity, short attention span, learning problems, behavioral issues, delayed development, and abnormal facial features. The abundance of problems the child will have all depends on the amount of alcohol consumed by the mother during pregnancy.

Fetal Alcohol Syndrome (FAS) refers to a group of physical and mental birth defects resulting from a women’s drinking alcohol heavily or at crucial stages during pregnancy. Fetal Alcohol Syndrome was first named and treated in the late 1960's. This condition results from the toxic effect of alcohol and its chemical factors on the developing fetus. FAS is the leading cause of mental retardation occurring in 1 out of every 750 births. The frequency of FAS occurs about 1.9 times out of every 1000 births according to the latest figures, and minor effects can be seen in up to 20% of pregnancies per year. This number changes drastically for women who are clearly alcoholics. As high as 29 children out of every 1000 births will suffer from FAS

Fetal Alcohol Spectrum Disorders describes the wide range of effects that can occur if a mother drank alcohol during pregnancy. These effects include physical abnormalities, mental problems, and/or learning disabilities with possible lifelong implications. The child affected is more likely to have trouble in school, problems with the law, participate in high risk behaviors and/or problems with drugs or alcohol. The most severe form of Fetal Alcohol Spectrum Disorders is known as fetal alcohol syndrome (FAS).

Today in class we talked about Fetal Alcohol Syndrome, and it is caused when a pregnant mother drinks heavily. It can be a physical or cognitive disease (Myers, 2014).

Alcohol is a type of teratogen, which is an agent that can caused birth defects to occur. The timing and the amount of exposure to a teratogen is crucial when it comes to a pregnancy. A mother’s use of alcohol can greatly affect an unborn child. The timing at which the effect of teratogens varies from person to person, but the time when the teratogens have the largest effect typically occurs during the periods of rapid prenatal development. Mothers who are pregnant, or who wish to become pregnant, should avoid consuming alcohol because the teratogens can affect the mother’s eggs. It is true that there are certain stages in the pregnancy where a certain amount of exposure to teratogens will only have little impact, but there is still some form of result. When
