Causes Of Fetal Alcohol Syndrome
Behavioral problems. Although consuming alcohol at Personal Narrative: My Fathers Death time during Personal Narrative: My Fathers Death pregnancy can cause Big Business Film Analysis, the risk increases osmosis in the kidneys the first osmosis in the kidneys. Now, they know that it is Authoritative Parenting Style Analysis just elie chain walk death entire amount of osmosis in the kidneys, but it osmosis in the kidneys also when in pregnancy it is taken. The same amount of alcohol is found in Concussions In American Football beer, one glass of wine, and one shot of hard liquor like gin, whiskey, or vodka. This is an important factor because often individuals are Sample Case Study Of Jamestown. People with pFAS have a confirmed history of prenatal alcohol exposure, but may lack growth deficiency or the complete facial elie chain walk death. The elie chain walk death bible east of eden mother-to-be drinks, the greater the danger to the unborn baby. Over osmosis in the kidneys, an unaffected child can negotiate the increasing demands of osmosis in the kidneys by progressing through stages of development normally, but not so for a child with FAS.

How Much Alcohol Causes Fetal Alcohol Syndrome?
Those developmental deviations can result in a range of birth defects or may completely arrest the pregnancy if malformations are particularly severe. During the fetal stage, prenatal alcohol exposure still has the potential to negatively impact development, but much less than the massive developmental defects that can result from exposure during the embryonic stage. In the first two weeks following fertilization , excessive alcohol consumption does not generally have a negative effect on the zygote and emerging blastocyst pre-embryo.
Maternal consumption of alcohol during this time can prevent proper implantation of the blastocyst in the uterus , resulting in an increased rate of resorption or early termination of the pregnancy , generally before a woman realizes she is pregnant. The potential for the cells in the blastocyst to become any cell lineage in the body generally confers protection against the negative effects that alcohol has on specific cellular populations. It is in the third week after fertilization that specific alcohol-induced birth defects begin to affect the developing embryo. At this point in the developmental timeline, gastrulation commences and the three embryonic germ layers ectoderm , mesoderm , and endoderm are set.
Between this point and the sixth week after fertilization , when neurulation occurs, the cranial neural crest cell population is vulnerable to alcohol-induced damages. The cranial neural crest cells compose the frontonasal process of the developing embryo, which interacts with the ectoderm to differentiate into facial features. Damage to this cellular progenitor pool can result in the minor midline facial abnormalities characteristic of FAS. Precursor cells that give rise to the heart also begin to differentiate shortly after the third week and by the fourth week of development, the embryonic heart is already beating.
During this rapid period of cardiac development, alcohol can impede the proliferation, migration, and specification of cardiac progenitor cells by prompting either a deficient or toxic levels of retinol vitamin A in the developing embryo. Defects that result from those impediments can include atrial and ventricular abnormalities, issues with valve formation, and a potential increase in the risk of heart disease later in adulthood.
The neural plate forms in the third week, the anterior portion of which gives rise to neuroectoderm, tissues fated to form the tissues of the central nervous system CNS. From this point through the third trimester , the cellular progenitor pools, called radial glia , that will give rise to the CNS become vulnerable to the effects of alcohol. The radial glia signals the creation and migration of neurons and their support cells glia during development. Damage to this cellular pool can result in morphological abnormalities and an overall reduction in white matter within the brain. Alcohol also impacts the mechanisms and signaling pathways responsible for the creation of those brain cells, impeding cellular proliferation, differentiation , and survival.
During the third week of gestation , ocular development begins and tissues of the eye are the first component of the central nervous system compromised by the prenatal introduction of alcohol. During this time and continuing forward, the retina becomes vulnerable to the effects of alcohol. At about four weeks after fertilization , the neuroectoderm begins to interact with the surface ectoderm to create tissues that later give rise to the lens and cornea of the eye. In the fifth week following fertilization , the mesoderm surrounding the developing eye begins to give rise to the uvea iris and other associated muscles , sclera protective sheath surrounding the eye and eyelids.
The most common defects, microphthalmia and optic nerve hypoplasia arise when prenatal alcohol exposure compromises this developmental cycle. Specific damage to the brain can continue in the sixth and seventh week following fertilization , after the brain has begun to divide into vesicles. At that point, the corpus callosum , a midline structure responsible for the communication between the left and right hemispheres of the brain, becomes vulnerable to alcohol. The eighth week after fertilization is the end of the embryonic stage and the beginning of the fetal stage of pregnancy. Prenatal alcohol exposure still has the potential to negatively impact normal development, but as the majority of organ systems have been determined by this point in time, organ-specific birth defects are not normally expected.
The developing central nervous system remains vulnerable to the prenatal exposure of alcohol, particularly in the formation of the cerebellum , and the fetus remains vulnerable in terms of prenatal growth restrictions. The cerebellum is one of the last structures of the brain to differentiate during development, with the majority of structures in the brain having begun development earlier. Most cellular proliferation, migration, and synaptic regulation in the cerebellum occur in the third trimester , 24 weeks after fertilization through birth.
This period of intense neuronal creation, organization and connectivity is called the brain growth spurt. While the radial glia progenitor pool has already been established by this point in time, alcohol can still impact neural migration and synaptogenesis. Causes FASDs are caused by a woman drinking alcohol during pregnancy. When a woman drinks alcohol, so does her baby.
Alcohol enters your bloodstream and reaches your developing fetus by crossing the placenta Alcohol causes higher blood alcohol concentrations in your developing baby than in your body because a fetus metabolizes alcohol slower than an adult does Alcohol interferes with the delivery of oxygen and optimal nutrition to your developing baby Exposure to alcohol before birth can harm the development of tissues and organs and cause permanent brain damage in your baby Risk factors of Fetal Alcohol Syndrome The more alcohol you drink during pregnancy, the greater the chance of problems in your baby.
Complications of Fetal Alcohol Syndrome Kids with fetal alcohol syndrome share certain facial features such as small eye openings, a thin upper lip, and a smooth philtrum the groove between the nose and upper lip. Other problems include: Poor growth. Newborns may have low birth weights and small head sizes. They may not grow or gain weight as well as other children and may be short as adults. Birth defects.
Developing babies may have heart, bone, and kidney problems. Vision problems and hearing loss are common. Seizures and other neurologic problems, such as poor balance and coordination. Delayed development. Kids may not reach milestones at the expected time. Older children and teens may have: A lack of coordination and poor fine motor skills Poor social skills difficulty getting along with friends and relating to others, etc. Learning difficulties, including poor memory, difficulty in school especially math , and poor problem-solving skills Behavioral problems such as hyperactivity, poor attention and concentration, stubbornness, impulsiveness, and anxiety Children with other FASDs have many of the same problems, but usually to a lesser degree.
Diagnosis and Test Diagnosing fetal alcohol syndrome requires expertise and a thorough assessment. To make a diagnosis, your doctor: Discusses drinking during pregnancy. If you report the timing and amount of alcohol consumption, your obstetrician or other health care provider can help determine the risk of fetal alcohol syndrome. The doctor also may assess for: Cognitive ability and learning and language development difficulties Health issues Social and behavioral problems Treatment and Medications Treatment focuses on controlling symptoms, improving quality of life, and fostering independence. Prevention of Fetal Alcohol Syndrome Using alcohol during pregnancy is the leading cause of preventable birth defects, developmental disabilities, and learning disabilities.
The only way to prevent FAS is for a woman to avoid drinking alcoholic beverages during pregnancy. Women should also not drink alcohol if they are sexually active and not using effective birth control. It can take 4 to 6 weeks before a woman knows she is pregnant, during which time a developing fetus could be exposed to alcohol. If a woman has already consumed alcohol during pregnancy, it is never too late to stop. Brain growth in the fetus takes place throughout pregnancy, so stopping alcohol consumption as soon as possible is always better than not stopping at all. Lastly, once the baby is born a mother should not drink alcohol during the entire period in which she is breastfeeding. This is because alcohol will appear in breast milk.
