Zespół alkoholowy płodu
Etiologia i przyczyny
Zespół alkoholowy płodu (ZAP, FAS) jest najcięższą formą zaburzeń ze spektrum poalkoholowych (FASD), wywołaną wyłącznie prenatalną ekspozycją na alkohol. Alkohol przenika przez łożysko do płodu, gdzie jego stężenie we krwi jest wyższe niż u matki z powodu wolniejszego metabolizmu, co wydłuża toksyczne działanie. Alkohol działa teratogennie, powodując uszkodzenia komórek, zaburzenia migracji neuronów, apoptozę w OUN oraz zwężenie naczyń łożyskowych, co ogranicza dostęp tlenu i składników odżywczych. Uszkodzenia OUN są trwałe i obejmują deficyty poznawcze, motoryczne i behawioralne. Ryzyko ZAP jest zależne od dawki, częstotliwości i czasu ekspozycji na alkohol w ciąży, przy czym picie w pierwszym trymestrze zwiększa ryzyko FASD 12-krotnie, w pierwszym i drugim trymestrze 61-krotnie, a we wszystkich trzech trymestrach 65-krotnie. Genetyczne polimorfizmy dehydrogenazy alkoholowej (ADH) mogą modyfikować podatność na ZAP, a czynniki takie jak wiek matki, stan odżywienia, stres, palenie tytoniu i wcześniejsze urodzenie dziecka z ZAP również wpływają na ryzyko.

Etiologia zespołu alkoholowego płodu (ZAP)
Zespół alkoholowy płodu (ZAP), znany również jako Fetal Alcohol Syndrome (FAS), jest najcięższą formą zaburzeń ze spektrum poalkoholowych (Fetal Alcohol Spectrum Disorders – FASD). Jest to stan spowodowany wyłącznie przez ekspozycję płodu na alkohol w czasie ciąży.12 ZAP stanowi jeden z najczęstszych możliwych do zapobieżenia powodów wad wrodzonych i niepełnosprawności intelektualnej w Stanach Zjednoczonych i na świecie.34
Mechanizm przenikania alkoholu do płodu
Mechanizm powstawania ZAP jest związany z bezpośrednim przeniknięciem alkoholu z krwiobiegu matki do płodu. Kiedy kobieta ciężarna spożywa alkohol, substancja ta szybko przedostaje się do jej krwiobiegu, a następnie przez łożysko dociera do rozwijającego się płodu.56 W łonie matki łożysko dostarcza tlen i składniki odżywcze rozwijającemu się dziecku, ale również umożliwia przenikanie szkodliwych substancji, w tym alkoholu.7
Co istotne, poziom alkoholu we krwi płodu jest wyższy niż we krwi matki, ponieważ organizm płodu rozkłada i eliminuje alkohol znacznie wolniej niż organizm dorosłego człowieka.89 To oznacza, że alkohol pozostaje w organizmie płodu dłużej, zwiększając czas narażenia tkanek i organów na jego toksyczne działanie.10
Bezpośrednie działanie toksyczne alkoholu
Alkohol działa jako teratogen, czyli substancja powodująca wady wrodzone u rozwijającego się płodu.11 Jego toksyczność wobec komórek płodu przejawia się na wielu poziomach:
- Alkohol jest toksyczny dla komórek płodu i może prowadzić do zniszczenia komórek w różnych częściach ciała rozwijającego się dziecka12
- Powoduje zaburzenia migracji komórek do odpowiednich części mózgu i tworzenia połączeń między neuronami13
- Aktywuje apoptozę (programowaną śmierć komórkową) w komórkach ośrodkowego układu nerwowego14
- Zaburza rozwój tkanek i narządów, powodując trwałe uszkodzenia mózgu płodu15
- Przez zwężenie naczyń krwionośnych spowalnia przepływ krwi do łożyska, tymczasowo ograniczając dostęp tlenu i składników odżywczych do płodu1617
Wpływ na centralny układ nerwowy
Ekspozycja na alkohol przed urodzeniem może poważnie zakłócić rozwój ośrodkowego układu nerwowego (OUN), w tym mózgu i rdzenia kręgowego.18 Choć dokładny mechanizm, w którym alkohol powoduje swoje teratogenne skutki, nie jest w pełni poznany, z badań na modelach zwierzęcych wiemy, że prenatalna ekspozycja na alkohol wpływa na wszystkie etapy rozwoju mózgu poprzez różne mechanizmy.19
Skutki działania alkoholu na OUN obejmują zaburzenia strukturalne, neurologiczne oraz funkcjonalne, które mogą prowadzić do trwałych zaburzeń poznawczych, motorycznych i behawioralnych.2021 Uszkodzenia OUN spowodowane prenatalną ekspozycją na alkohol są trwałe i nieodwracalne – nie istnieje lek na FASD.2223
Czynniki ryzyka i podatność na rozwój ZAP
Wystąpienie i nasilenie zespołu alkoholowego płodu zależy od wielu czynników, które mogą modyfikować ryzyko jego rozwoju. Choć spożywanie alkoholu przez matkę w czasie ciąży jest jedyną konieczną przyczyną ZAP, istnieje wiele czynników, które mogą wpływać na stopień uszkodzenia płodu.2425
Ilość, częstotliwość i czas spożycia alkoholu
Kluczowymi czynnikami ryzyka rozwoju ZAP są:
- Ilość spożywanego alkoholu – im większa ilość alkoholu, tym większe ryzyko2627
- Częstotliwość spożywania – regularne picie zwiększa ryzyko2829
- Epizodyczne upijanie się (binge drinking) – stanowi najbardziej ryzykowny wzorzec spożycia3031
- Czas ekspozycji podczas ciąży32
Badania wykazały, że ryzyko pojawienia się skutków związanych z alkoholem wzrasta wraz ze wzrostem spożycia alkoholu przez matkę w sposób zależny od dawki.33 Ponadto, picie alkoholu w poszczególnych trymestrach ciąży różnie wpływa na prawdopodobieństwo wystąpienia ZAP:34
- Picie w pierwszym trymestrze zwiększa prawdopodobieństwo FASD 12-krotnie
- Picie w pierwszym i drugim trymestrze zwiększa prawdopodobieństwo FASD 61-krotnie
- Picie we wszystkich trzech trymestrach zwiększa prawdopodobieństwo FASD 65-krotnie
Czynniki genetyczne i metaboliczne
Podatność genetyczna na ZAP została sugerowana w niektórych badaniach, z polimorfizmami dehydrogenazy alkoholowej (ADH) jako czynnikiem ryzyka.35 W szczególności, allele ADH 2*2 i 2*3, które skutkują szybkim metabolizmem alkoholu do aldehydu octowego, wykazywały działanie ochronne przeciwko ZAP.36
Mechanizm tego ochronnego działania nie jest w pełni poznany. Niektórzy sugerują, że szybki metabolizm alkoholu do aldehydu octowego obniża szczytowy poziom alkoholu we krwi, co zmniejsza ekspozycję płodu.37 Alternatywnie, szybki metabolizm może zwiększać poziom aldehydu octowego, powodując nieprzyjemne efekty u matki, a tym samym zmniejszać poziom spożycia alkoholu, co obniża ekspozycję płodu.38
Badacze z Uniwersytetu Louisville prowadzą badania nad genetycznymi czynnikami ryzyka FASD, wykorzystując ryby danio pręgowane (zebrafish), które dzielą 82% takich samych genów jak ludzie.3940 Wczesne badania wskazują, że mogą istnieć stosunkowo proste sposoby ochrony przed FASD, takie jak modyfikacja składu witamin prenatalnych w celu zmniejszenia ryzyka.41
Czynniki środowiskowe i demograficzne
Na ryzyko rozwoju ZAP wpływają również inne czynniki:
- Wiek matki – kobiety powyżej 30 roku życia i/lub z długą historią spożywania alkoholu mogą być bardziej narażone na urodzenie dziecka z ZAP42
- Stan odżywienia matki – zły stan odżywienia może zwiększyć prawdopodobieństwo posiadania dziecka dotkniętego alkoholem4344
- Posiadanie już jednego dziecka z ZAP dodatkowo zwiększa ryzyko urodzenia kolejnych dzieci z tym zespołem45
- Czynniki stresu46
- Palenie tytoniu lub używanie innych substancji47
Wpływ alkoholu na różne etapy rozwoju płodu
Działanie alkoholu na płód zależy od etapu rozwoju prenatalnego, w którym następuje ekspozycja. Alkohol może uszkodzić płód na każdym etapie ciąży, w tym w pierwszych tygodniach, kiedy kobieta może jeszcze nie wiedzieć, że jest w ciąży.4849
Pierwszy trymestr ciąży
Pierwszy trymestr ciąży jest kluczowym okresem dla rozwoju organów i tkanek:5051
- Mózg, serce i naczynia krwionośne zaczynają się rozwijać we wczesnych tygodniach ciąży
- W pierwszych trzech miesiącach ciąży zachodzą ważne etapy rozwoju twarzy oraz narządów, takich jak serce, kości, mózg i nerwy
- Według wielu badań, spożywanie alkoholu wydaje się być najbardziej szkodliwe właśnie w tym okresie
- Narażenie na działanie alkoholu w tym okresie może powodować uszkodzenia fizyczne w rozwoju ciała płodu
W pierwszym trymestrze najbardziej narażone na działanie alkoholu są ośrodkowy układ nerwowy, narządy wzroku, słuchu, nerki, wątroba i serce.52 Alkohol przedostaje się przez łożysko do organizmu płodu już w drugim tygodniu życia.53
Drugi i trzeci trymestr ciąży
Mimo że najwrażliwszym okresem na działanie alkoholu jest pierwszy trymestr, ekspozycja w drugim i trzecim trymestrze ciąży również może mieć poważne konsekwencje:5455
- Mózg nadal rozwija się w tych okresach, a nawet umiarkowane ilości alkoholu mogą zakłócić ten proces
- Ekspozycja na alkohol w późniejszym okresie ciąży może prowadzić do problemów z koncentracją, krótkotrwałą pamięcią, trudnościami w przyswajaniu nowych informacji oraz trudnościami z planowaniem i przewidywaniem konsekwencji działań56
- W ostatnim trymestrze alkohol opóźnia przyrost masy ciała i rozwój płuc, może również powodować przedwczesny poród57
Picie w każdym z trzech trymestrów stanowi zagrożenie.58 W konsekwencji kobiety mogą zmniejszyć ryzyko związanych z alkoholem skutków dla płodu poprzez zmniejszenie dawki lub zaprzestanie spożywania alkoholu jak najszybciej w czasie ciąży.59
Brak bezpiecznej dawki alkoholu w ciąży
Obecne dowody naukowe jednoznacznie wskazują, że nie istnieje bezpieczna ilość alkoholu, którą można spożywać w czasie ciąży.6061 Wszystkie główne organizacje medyczne, w tym Amerykańska Akademia Pediatrii, Amerykańskie Kolegium Położników i Ginekologów, Amerykańska Akademia Lekarzy Rodzinnych oraz Główny Chirurg USA, zgodnie twierdzą, że najlepszą radą jest całkowite powstrzymanie się od picia alkoholu podczas ciąży lub planowania ciąży.62
Aktualne stanowisko organizacji medycznych
Niskie do umiarkowanych poziomy spożycia alkoholu przez matkę nie zostały dobrze zbadane w ludzkiej ciąży, ale dowody nie wskazują na istnienie dawki progowej, poniżej której nie obserwuje się wpływu na funkcje poznawcze lub zachowanie.63 W świetle braku wystarczających danych, żaden poziom spożycia alkoholu w ciąży nie jest uznawany za bezpieczny.64
Centra Kontroli i Prewencji Chorób (CDC), Amerykańska Akademia Pediatrii i Amerykański Kongres Położników i Ginekologów nie uznają żadnej bezpiecznej ilości spożycia alkoholu podczas ciąży i zalecają całkowitą abstynencję.65 Biorąc pod uwagę, że około połowa wszystkich ciąż w Stanach Zjednoczonych nie jest planowana, Główny Chirurg USA zaleca, aby kobiety, które są w ciąży, mogą być w ciąży lub planują zajść w ciążę, w ogóle nie piły alkoholu.66
Wzorce spożycia związane z najwyższym ryzykiem
Badania pokazują, że picie nadmierne (tzw. binge drinking) i regularne spożywanie dużych ilości alkoholu podczas ciąży stanowią największe ryzyko dla rozwijającego się płodu.6768 Jednak nawet mniejsze ilości mogą powodować szkody.69
Ryzyko ZAP wzrasta wraz z ilością spożywanego alkoholu, częstotliwością spożycia i dłuższym czasem spożywania alkoholu w czasie ciąży.70 Stężenie alkoholu we krwi zostało zidentyfikowane jako istotny czynnik. Wszystkie formy alkoholu, takie jak piwo, wino i mocne alkohole, stwarzają podobne ryzyko.71
U kobiet, które spożywają jakąkolwiek ilość alkoholu podczas ciąży, ryzyko urodzenia dziecka z FASD wynosi około 15%, a z FAS około 1,5%. Picie 2 standardowych drinków dziennie lub 6 standardowych drinków w krótkim czasie wiąże się z 4,3% ryzykiem urodzenia dziecka z FAS (czyli jedna na 23 kobiety w ciąży, które piją dużo alkoholu, urodzi dziecko z FAS).72
Zapobieganie zespołowi alkoholowemu płodu
Zespół alkoholowy płodu jest w 100% możliwy do zapobieżenia.7374 Jedynym skutecznym sposobem zapobiegania ZAP jest całkowite unikanie spożywania alkoholu przez kobiety w ciąży.7576
Kluczowe zalecenia dla kobiet w ciąży
Najważniejsze zalecenia dotyczące zapobiegania ZAP obejmują:7778
- Całkowite unikanie alkoholu w czasie ciąży – nie ma bezpiecznej ilości, rodzaju ani czasu spożycia alkoholu podczas ciąży
- Zaprzestanie picia alkoholu przy planowaniu ciąży – zapobiega to narażeniu płodu na alkohol we wczesnych tygodniach ciąży, zanim kobieta dowie się o ciąży
- Natychmiastowe zaprzestanie picia alkoholu po stwierdzeniu ciąży – może to zmniejszyć ryzyko dla płodu
- Poszukiwanie pomocy w przypadku problemów z alkoholem – leczenie uzależnienia od alkoholu u matki może pomóc w lepszym rodzicielstwie i zapobiec narażeniu przyszłych ciąż
Ponieważ wszystkie FASD są spowodowane ekspozycją na alkohol przed urodzeniem, jedynym sposobem na uniknięcie tych zaburzeń jest całkowite powstrzymanie się od picia alkoholu podczas całej ciąży, od poczęcia do porodu.79
Edukacja i świadomość społeczna
Zwiększanie świadomości i edukacja na temat ryzyka związanego z piciem alkoholu w czasie ciąży są kluczowe dla zmniejszenia występowania ZAP.80 Wielu badaczy uważa, że przypadki FASD są szeroko niedoszacowane z powodu słabej świadomości społecznej i błędnych przekonań na temat tego, co jest bezpieczne do picia w czasie ciąży.81
Według szacunków, zaburzenia ze spektrum poalkoholowego mogą dotykać nawet 5% całej populacji USA, co czyni to zaburzenie równie lub bardziej powszechnym niż inne niepełnosprawności rozwojowe, takie jak autyzm.82
Biorąc pod uwagę, że około 10% kobiet zgłasza spożywanie alkoholu podczas ciąży, konieczne jest dalsze podnoszenie świadomości społecznej na temat ryzyka związanego z alkoholem w czasie ciąży.83

Fetal alcohol syndrome is one of the five disorders that comprise fetal alcohol spectrum disorders (FASD). […] All of the conditions that comprise fetal alcohol spectrum disorders stem from one common cause, which is prenatal exposure to alcohol. Alcohol is extremely teratogenic to a fetus. Its effects are wide-ranging and irreversible. […] In summary, any amount of alcohol consumed at any point during pregnancy has the potential cause of irreversible damage that can lead to a fetal alcohol spectrum disorder. […] Prenatal alcohol exposure is the leading cause of preventable congenital disabilities. […] The exact mechanism by which alcohol causes its teratogenic effects is not known. […] We do know that alcohol is a teratogen that causes irreversible damage to the central nervous system (CNS).

Alcohol exposure during pregnancy can result in FASD by interfering with development of the babys brain and other critical organs and physiological functions. […] Research shows that binge drinking and heavy drinking during pregnancy put a developing baby at the greatest risk for severe problems. […] However, even lesser amounts can cause harm. […] In fact, there is no known safe amount of alcohol consumption during pregnancy. […] Given that approximately half of all pregnancies in the United States are not planned, the U.S. Surgeon General recommends that women who are pregnant, might be pregnant, or are thinking about getting pregnant should not drink alcohol at all.

Fetal alcohol syndrome (FAS) is the most severe fetal alcohol spectrum disorder. These are a group of conditions present at birth that can happen when a pregnant person drinks alcohol. […] Alcohol — including wine, beer, and liquor — is the leading preventable cause of birth defects in the U.S. […] In the womb, a baby doesn’t have a fully developed liver that can process or break down alcohol, so it can easily get to and damage the baby’s organs. […] Some of the most severe problems happen when a pregnant person drinks in the first trimester, when the baby’s brain starts to develop. But the second and third trimesters aren’t safe either. The brain is still developing then, and even moderate amounts of alcohol can disturb this process. […] There is no „safe” amount of alcohol you can drink during pregnancy. And there is no time during pregnancy when it’s considered safe to drink alcohol.
- #5 About Fetal Alcohol Spectrum Disorders (FASDs) | Fetal Alcohol Spectrum Disorders (FASDs) | CDChttps://www.cdc.gov/fasd/about/index.html
FASDs can occur when a person is exposed to alcohol before birth. Alcohol in the mother’s blood passes to the baby through the umbilical cord. […] There is no known safe amount of alcohol during pregnancy or when trying to get pregnant. There is also no safe time to drink during pregnancy. Alcohol can cause problems for a developing baby throughout pregnancy, including before a woman knows she’s pregnant. All types of alcohol are equally harmful, including all wines and beer.

FASD is caused when a mother drinks alcohol during pregnancy. FASD is not hereditary. […] Alcohol is known to harm the normal development of cells. If you’re pregnant and drink alcohol, it passes into your developing fetus. This can cause harm to the baby’s brain and body. […] The impact of alcohol on a developing fetus is influenced by the: amount (how much you drink at once), frequency (how often alcohol was consumed), timing (when alcohol was consumed in pregnancy).
- #8 Fetal alcohol syndrome – Symptoms and causes – Mayo Clinichttps://www.mayoclinic.org/diseases-conditions/fetal-alcohol-syndrome/symptoms-causes/syc-20352901
Alcohol causes a higher blood alcohol level in your developing baby than in your body. That’s because a baby breaks down and gets rid of alcohol slower than an adult does. […] Alcohol is toxic to the baby’s cells. Exposure to alcohol before birth can harm how the body develops and cause permanent brain damage in the developing baby. […] The more you drink while pregnant, the greater the risk to your unborn baby. But any amount of alcohol puts your baby at risk. Your baby’s brain, heart and blood vessels begin to develop in the early weeks of pregnancy, before you may know you’re pregnant. […] During the first three months of pregnancy, important stages of development happen with the face and organs such as the heart, bones, brain and nerves. Drinking alcohol during this time can cause damage to how body parts develop. And as the baby continues to develop in the womb, it’s damaging to drink at any time during pregnancy.

Fetal alcohol syndrome (FAS) refers to a set of physical and mental defects that are caused by a mother consuming alcohol during pregnancy. […] No amount of alcohol has been shown to be safe to consume during pregnancy and anyone who drinks during this time places their baby at risk of developing FAS. […] FAS is caused by alcohol in the mothers bloodstream crossing the placenta and reaching the fetus. […] The blood alcohol concentration in the developing fetus is much higher than in the mothers blood because the fetus metabolizes alcohol much more slowly than the mother does. […] In the fetus, alcohol impairs the delivery of oxygen and nutrients to developing tissues and organs. […] Damage to the baby may also be caused by drinking at any other point throughout the pregnancy.

What Causes Fetal Alcohol Syndrome? Fetal alcohol syndrome (FAS), also commonly referred to as fetal alcohol spectrum disorders (FASDs), is a syndrome and spectrum of disorders that occur in babies who were exposed to alcohol while they were in utero. Exposure to alcohol in the womb can cause a number of problems in babies and children, including brain damage, growth problems, intellectual disabilities, developmental delays, and behavioral problems. […] Fetal alcohol syndrome is caused by a pregnant mother consuming alcohol, which then spreads to the fetus through the umbilical cord. Unlike an adult, a fetus is unable to metabolize alcohol, and it will stay in the system longer than is safe. Alcohol will interfere with the normal development of a fetus, particularly the brain and nervous systems. Alcohol can kill cells in various parts of the fetus, resulting in abnormal physical development. Alcohol will also interfere with the way nerves develop, including how they travel throughout the body and how they communicate. Alcohol can constrict the blood vessels, slowing blood flow to the placenta and temporarily limiting the oxygen and nutrients that can reach the fetus. This restriction, even if temporary, can have terrible effects on the fetusâ development. […] A baby in utero exposed to alcohol can experience a number of detrimental developmental effects, all of which are preventable by a pregnant mother avoiding alcohol consumption during pregnancy.

A developing baby is exposed to the same concentration of alcohol as the mother during pregnancy. […] Alcohol crosses the placenta within minutes, resulting in similar blood concentration in the baby as is present in the mother. […] As a teratogenâan agent that causes birth defectsâalcohol is a toxic substance to a developing baby, and can cause: […] Prenatal exposure to alcohol can cause damage to a developing baby at any time. […] The extent of alcoholâs effect on a developing baby may also depend on the motherâs genetic make-up, her childâs genetic make-up, and changes in gene activity caused by prenatal alcohol exposure.

- #12 Preventing Fetal Alcohol Syndrome: Understanding the Causes, Symptoms, and Riskshttps://browntrialfirm.com/birth-injury-lawyer/fetal-alcohol-syndrome/
Fetal alcohol syndrome is the most severe type of FASD, characterized by physical, mental, and behavioral problems in children that can last into adulthood. […] As mentioned, FAS can occur if a pregnant woman drinks alcohol during pregnancy, which affects the developing babys brain, heart and other organs, resulting in physical and mental issues. […] The severity of FAS depends on the amount of alcohol and the stage of pregnancy when the alcohol was consumed. […] It is known, however, that the more alcohol a pregnant woman drinks, the higher the risk of FAS for her baby. […] Alcohol can affect a growing baby in a number of ways: It destroys cells in the fetus, leading to abnormal physical growth. […] It produces toxic byproducts that concentrate in the fetuss brain and lead to brain damage. […] It interferes with nerve cell development, which can affect brain function. […] The frequency and amount of alcohol a mother drinks before and during pregnancy, the stage of fetal development when alcohol is consumed, and the genetics of mother and baby are factors that influence the risk of FAS.

Fetal Alcohol Syndrome (FAS) is a serious health condition arising from prenatal alcohol exposure, leading to lifelong physical, cognitive, and behavioral difficulties. […] The primary cause of FAS is the consumption of alcohol by a pregnant woman. […] Alcohol’s effect on the developing fetus is profound; it constricts blood vessels, reducing blood flow to the placenta and leading to a shortage of oxygen and nutrients. […] The condition is entirely preventable by abstaining from alcohol during pregnancy. […] Alcohol exposure during pregnancy is widely recognized as a significant risk factor for fetal development, leading to a range of conditions collectively known as fetal alcohol spectrum disorders (FASDs). […] Alcohol is a teratogen, which means it can disrupt the normal development of the embryo or fetus. […] The severity of the effects can vary, depending on factors such as the amount and timing of alcohol exposure, maternal health, and genetic vulnerability of the fetus to alcoholism.
- #18 Fetal Alcohol Spectrum Disorders (FASD) | CAMHhttps://www.camh.ca/en/health-info/mental-illness-and-addiction-index/fetal-alcohol-spectrum-disorder
Fetal Alcohol Spectrum Disorder (FASD) is a lifelong disability that affects the brain and body of individuals who were exposed to alcohol in the womb. […] When a woman consumes alcohol while pregnant, her fetus is exposed directly to alcohol through her bloodstream. Alcohol can interfere with the growth and development of all fetal body systems; however, the developing central nervous system (the brain and spinal cord) is especially vulnerable to the damaging effects of alcohol. […] FASD is preventable. There is no safe amount or type of alcoholic beverage, and no safe time to drink alcohol during pregnancy. Pregnant women are advised not to drink any alcohol during pregnancy.
- #19 Fetal Alcohol Syndrome – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK448178/
From animal models, we know that prenatal alcohol exposure affects all stages of brain development through a variety of mechanisms, the most significant of which result in cognitive, motor, and behavioral dysfunction. […] Given that the CNS damage from prenatal alcohol exposure is permanent, there is no cure for fetal alcohol spectrum disorders.

The diagnosis of FAS is predominantly clinical and is based on the presence of the 3 key signs: growth retardation (pre or postnatal), presence of characteristic facial dysmorphisms, abnormalities in the central nervous system, as well as the presence of suspected or confirmed intrauterine exposure to alcohol. […] Children with FAS exhibit central nervous system dysfunction of varying degrees, which may include structural, neurological, or functional abnormalities or combinations thereof. […] There is no treatment for FAS and the therapies implemented are only supportive. However, it has been shown that early diagnosis can reduce the occurrence of secondary disabilities such as isolation, lack of independent life and problems with work. […] This category includes all those subjects who do not fully meet the FAS criteria, but have a history of exposure to alcohol, peculiar dysmorphisms and alterations of the central nervous system.

The symptoms of this condition will be with the person throughout their entire life.
- #24 Fetal Alcohol Syndrome: Background, Pathophysiology, Etiologyhttps://emedicine.medscape.com/article/974016-overview
Although many factors may modify the risk, the primary and only necessary cause of fetal alcohol syndrome (FAS) or fetal alcohol spectrum disorder (FASD) is maternal alcohol consumption. […] The quantity and pattern of maternal drinking and, therefore, the dose and duration of exposure to alcohol are the critical factors in conferring risk. […] Current evidence supports the conclusion that women who drink heavily during pregnancy may produce children with features of fetal alcohol syndrome. […] Low-to-moderate levels of maternal alcohol consumption have not been well studied in human pregnancy, but evidence has not suggested a threshold dose below which no effects on cognitive performance or behavior are seen. […] In the absence of adequate data, no level of alcohol consumption in pregnancy is known to be safe, and the US Surgeon General advises women who are pregnant or who may be pregnant to abstain from alcohol consumption throughout the gestation.

Foetal alcohol spectrum disorders (FASDs) are a leading cause of developmental disability. Prenatal alcohol use is the sole necessary cause of FASD, but it is not always sufficient. […] The aetiology of FASD is multifaceted and complex. FASD risk is determined by a range of lifestyle, sociodemographic, maternal, social, gestational, and genetic factors. […] Maternal alcohol use is the sole necessary cause of FASD, but it is not always sufficient. […] Alcohol interacts with multiple factors in a complex process to determine offspring outcome. […] The term risk factor obscures the distinction between a predictor variable and a cause. […] Causal knowledge is important for identifying effective mechanisms for prevention and intervention programmes. […] The DAG that we have presented provides a summary of the distal and proximal factors that are proposed to causally influence FASD risk, as well as the factors that are proxies for causal factors or (non-causal) risk markers for FASD.

Fetal Alcohol Syndrome (FAS) is an alcohol-related birth disability and is the number one cause of intellectual disability in the United States. It is also the only cause of birth defects that is entirely preventable. The condition occurs from maternal alcohol use during pregnancy. When a pregnant woman drinks alcohol, it passes through the placenta and is absorbed by the unborn baby. […] Prenatal alcohol exposure does not always result in FAS although there is no known safe level of alcohol consumption during pregnancy. […] Alcohol-Related Neurodevelopmental Disorder (ARND) describes the functional or cognitive impairments linked to prenatal alcohol exposure, and Alcohol-Related Birth Defects (ARBD) describes malformations in the skeletal and major organ systems. […] Individuals with FAS have a distinct pattern of facial abnormalities, growth deficiency and evidence of central nervous system dysfunction.

FASD is caused when a mother drinks alcohol during pregnancy. FASD is not hereditary. […] Alcohol is known to harm the normal development of cells. If you’re pregnant and drink alcohol, it passes into your developing fetus. This can cause harm to the baby’s brain and body. […] The impact of alcohol on a developing fetus is influenced by the: amount (how much you drink at once), frequency (how often alcohol was consumed), timing (when alcohol was consumed in pregnancy).

- #31 Fetal alcohol spectrum disorder – Wikipediahttps://en.wikipedia.org/wiki/Fetal_alcohol_spectrum_disorder
The risk of FASD increases with the amount consumed, the frequency of consumption, and a longer duration of alcohol consumption during pregnancy. Blood alcohol concentration has been identified as a relevant factor. All forms of alcohol, such as beer, wine, and liquor, pose similar risk. Binge drinking increases the chances and severity of FASD to such an extent that Svetlana Popova has stated that „binge drinking is the direct cause of FAS or FASD”. Small amounts of alcohol may not cause an abnormal appearance, however, small amounts of alcohol consumption while pregnant may cause behavioral problems and also increases the risk of miscarriage. Quasi-experimental studies provide moderately strong evidence that prenatal alcohol exposure causes detrimental cognitive outcomes, and some evidence of reduced birthweight, although no study was fully rated at low risk of bias and quantity of studies was limited.

FASD can include physical, mental, behavioral, and/or learning disabilities with possible lifelong implications. […] Since there is no known safe amount of alcohol that can be consumed during pregnancy, it is advised by all major medical associations, including the Centers for Disease Control, the American Academy of Pediatrics, and the U.S. Surgeon General, that if a woman is pregnant or could become pregnant, they should abstain from drinking alcohol. […] Prenatal alcohol exposure is the leading preventable cause of birth defects in the United States.

Alcohol causes a higher blood alcohol level in your developing baby than in your body. That’s because a baby breaks down and gets rid of alcohol slower than an adult does. […] Alcohol is toxic to the baby’s cells. Exposure to alcohol before birth can harm how the body develops and cause permanent brain damage in the developing baby. […] The more you drink while pregnant, the greater the risk to your unborn baby. But any amount of alcohol puts your baby at risk. Your baby’s brain, heart and blood vessels begin to develop in the early weeks of pregnancy, before you may know you’re pregnant. […] During the first three months of pregnancy, important stages of development happen with the face and organs such as the heart, bones, brain and nerves. Drinking alcohol during this time can cause damage to how body parts develop. And as the baby continues to develop in the womb, it’s damaging to drink at any time during pregnancy.

[…] As a consequence, women can reduce their risk for alcohol-related birth outcomes by reducing the dose or by discontinuing the consumption of alcohol as soon as possible in the pregnancy.
- #60 About Fetal Alcohol Spectrum Disorders (FASDs) | Fetal Alcohol Spectrum Disorders (FASDs) | CDChttps://www.cdc.gov/fasd/about/index.html
FASDs can occur when a person is exposed to alcohol before birth. Alcohol in the mother’s blood passes to the baby through the umbilical cord. […] There is no known safe amount of alcohol during pregnancy or when trying to get pregnant. There is also no safe time to drink during pregnancy. Alcohol can cause problems for a developing baby throughout pregnancy, including before a woman knows she’s pregnant. All types of alcohol are equally harmful, including all wines and beer.

Alcohol exposure during pregnancy can result in FASD by interfering with development of the babys brain and other critical organs and physiological functions. […] Research shows that binge drinking and heavy drinking during pregnancy put a developing baby at the greatest risk for severe problems. […] However, even lesser amounts can cause harm. […] In fact, there is no known safe amount of alcohol consumption during pregnancy. […] Given that approximately half of all pregnancies in the United States are not planned, the U.S. Surgeon General recommends that women who are pregnant, might be pregnant, or are thinking about getting pregnant should not drink alcohol at all. […] Prenatal alcohol exposure is a leading preventable cause of birth defects and neurodevelopmental disorders in the United States.

There is no safe type of alcoholic beverage to consume while pregnant. […] No, there is no point during pregnancy when drinking alcohol is considered safe. […] FASDs can only happen when a pregnant person consumes alcohol. […] There is no evidence that FASDs are genetic or hereditary. FASDs can only happen if someone consumes alcohol while they are pregnant. […] Every major medical organization in the United States, including the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, the American Academy of Family Physicians, the US Surgeon General, and the CDC, agree and consistently state that the best advice is for people not to drink alcohol while they are pregnant or trying to become pregnant.

Although many factors may modify the risk, the primary and only necessary cause of fetal alcohol syndrome (FAS) or fetal alcohol spectrum disorder (FASD) is maternal alcohol consumption. […] The quantity and pattern of maternal drinking and, therefore, the dose and duration of exposure to alcohol are the critical factors in conferring risk. […] Current evidence supports the conclusion that women who drink heavily during pregnancy may produce children with features of fetal alcohol syndrome. […] Low-to-moderate levels of maternal alcohol consumption have not been well studied in human pregnancy, but evidence has not suggested a threshold dose below which no effects on cognitive performance or behavior are seen. […] In the absence of adequate data, no level of alcohol consumption in pregnancy is known to be safe, and the US Surgeon General advises women who are pregnant or who may be pregnant to abstain from alcohol consumption throughout the gestation.

- #68 Fetal alcohol spectrum disorder – Wikipediahttps://en.wikipedia.org/wiki/Fetal_alcohol_spectrum_disorder
The risk of FASD increases with the amount consumed, the frequency of consumption, and a longer duration of alcohol consumption during pregnancy. Blood alcohol concentration has been identified as a relevant factor. All forms of alcohol, such as beer, wine, and liquor, pose similar risk. Binge drinking increases the chances and severity of FASD to such an extent that Svetlana Popova has stated that „binge drinking is the direct cause of FAS or FASD”. Small amounts of alcohol may not cause an abnormal appearance, however, small amounts of alcohol consumption while pregnant may cause behavioral problems and also increases the risk of miscarriage. Quasi-experimental studies provide moderately strong evidence that prenatal alcohol exposure causes detrimental cognitive outcomes, and some evidence of reduced birthweight, although no study was fully rated at low risk of bias and quantity of studies was limited.

- #72 Fetal alcohol spectrum disorder – Wikipediahttps://en.wikipedia.org/wiki/Fetal_alcohol_spectrum_disorder
Fetal alcohol spectrum disorders are caused by alcohol exposure during gestational development. If an individual was not exposed to alcohol before birth, they will not have FASD. However, not all infants exposed to alcohol in utero will have detectable FAS, FASD, or pregnancy complications. […] No safe level of fetal alcohol exposure has been established. Because alcohol is a known teratogen, it is considered unethical to do randomized controlled trials on pregnant women to determine the precise toxicity effects of alcohol. Among women who consume any quantity of alcohol during pregnancy, the risk of giving birth to a child with FASD is about 15%, and to a child with FAS about 1.5%. Drinking 2 standard drinks a day, or 6 standard drinks in a short time, carries a 4.3% risk of a FAS birth (i.e. one of every 23 heavy-drinking pregnant women will deliver a child with FAS). Furthermore, alcohol-related congenital abnormalities occur at an incidence of roughly one out of 67 women who drink alcohol during pregnancy.

Fetal alcohol syndrome (FAS) is a group of abnormalities in babies born to mothers who consume alcohol during pregnancy. […] Many drugs can pass from the mother’s blood stream through the placenta to the fetus. Alcohol is no exception. Alcohol is broken down more slowly in the immature body of the fetus than in an adult’s body. This can cause the alcohol levels to remain high and stay in the baby’s body longer. […] The full picture of FAS usually occurs in babies born to alcoholic mothers, or those who drink more than four to five drinks/day. However, no amount of alcohol is safe. Even light or moderate drinking can affect the developing fetus. […] In addition to the acute effects of withdrawal, babies often suffer the teratogenic (causing abnormalities in formation) effects of alcohol. Specific deformities of the head and face, heart defects, and intellectual disability are seen with fetal alcohol syndrome (FAS). […] Fetal alcohol syndrome is 100 percent preventable. However, it requires that a mother stop using alcohol before becoming pregnant. Because no amount of alcohol is proven safe, women should stop drinking immediately if pregnancy is suspected.

[…] The full picture of FAS usually occurs in babies born to alcoholic mothers, or to those who drink regularly or binge-drink. However, no amount of alcohol is safe. Even light or moderate drinking can affect the developing fetus. […] Alcohol use in pregnancy has significant effects on the fetus and the baby. Dependence and addiction to alcohol in the mother also cause the fetus to become addicted.

Alcohol is a „teratogen,” something known to cause abnormalities in a fetus after prenatal exposure. Alcohol consumed by a pregnant person can reach the fetus and interfere with development of the brain and other body organs. A child exposed to alcohol before birth may face a lifetime of challenges from what are called fetal alcohol spectrum disorders. […] The term fetal alcohol spectrum disorders, or FASDs, describes a broad group of conditions that result from prenatal alcohol exposure. […] FASDs are 100% preventable. The only sure way to prevent FASDs is to completely avoid alcohol use while pregnant. […] There is no safe amount of alcohol when a person is pregnant. […] The more alcohol a developing fetus is exposed to, the higher the risk is for the developing fetus to have alcohol-related brain and organ damage.

Fetal alcohol syndrome causes learning problems, difficulty concentrating and even intellectual disability. […] Fetal alcohol syndrome, unfortunately, harms overall life expectancy. […] Fetal alcohol syndrome cannot be treated itself, but the impact of the symptoms that it causes may be lessened with treatment. […] While fetal alcohol syndrome is impossible to treat, it is very easy to prevent. Not drinking alcohol while pregnant makes the risk of fetal alcohol syndrome almost 0%.
- #77 Fetal Alcohol Syndromehttps://www.aapos.org/glossary/fetal-alcohol-syndrome
Fetal Alcohol Syndrome (FAS) happens when a baby is born to a mother who drank alcohol while pregnant. It causes problems that last a lifetime. There is no safe amount of alcohol to drink during pregnancy. Women who are pregnant should not drink any alcohol. […] FAS is part of a bigger group of problems called Fetal Alcohol Spectrum Disorders (FASD). FASD includes any problems to children caused by alcohol during pregnancy. All types of alcohol are harmful, including wine and beer. […] When a pregnant woman drinks, the alcohol gets into her blood. The alcohol in the mothers blood then goes to the babys blood and organs like the heart, brain and kidneys. The baby cant get rid of the alcohol like the mother can. This means the alcohol stays in the baby longer and harms the baby. […] Yes! The best way to prevent FAS is to not drink any alcohol during pregnancy. If someone is trying to get pregnant, it is best not to drink alcohol. If someone finds out that they are pregnant, it is best to stop drinking alcohol right away and speak with their doctor about possible problems from alcohol during pregnancy. Remember: there is no known „safe” amount of alcohol during pregnancy. All types of alcohol, including beer and wine, can harm a baby.

- #80 How Much Drinking Causes Fetal Alcohol Syndrome?https://twilightrecoverycenter.com/how-much-drinking-causes-fetal-alcohol-syndrome/
Studies suggest that binge drinking, which is when someone consumes four or more drinks at a time, is particularly harmful. […] The safest approach is complete abstinence from alcohol during pregnancy to avoid any risk of harm to the developing fetus. […] Fetal Alcohol Spectrum Disorder is a range of conditions that are associated with prenatal alcohol exposure, causing lifelong physical, behavioral, and cognitive impairments. […] FASD is caused by alcohol crossing the placenta and affecting fetal development, particularly the brain, which can happen when a woman engages in alcohol use during pregnancy. […] Prevention is entirely possible by abstaining from alcohol during pregnancy, making awareness and education crucial for reducing the incidence of FASD. […] Any amount of alcohol during pregnancy can potentially cause Fetal Alcohol Syndrome or other Fetal Alcohol Spectrum Disorders. […] The severity of the effects can vary based on factors such as the timing of alcohol exposure, the frequency and quantity consumed, and individual differences in metabolism and genetics, but any amount of alcohol use while pregnant can result in Fetal Alcohol Spectrum Disorders.

Fetal alcohol spectrum disorder can be triggered by both small and large amounts of drinking during pregnancy. […] Currently, the CDC estimates that 1 out of every 1,000 children is affected by FASD. […] Many researchers believe that FASD cases are widely unreported due to poor public awareness and misconceptions about what is safe to drink during pregnancy. […] In fact, it’s estimated that fetal alcohol spectrum disorder could affect up to 5% of the entire U.S. population, making this disorder equal to or more prevalent than other developmental disabilities such as autism. […] The symptoms can vary from child to child, but defects caused by fetal alcohol syndrome or other fetal alcohol-related disorders can only be treated, not reversed.

Drinking during pregnancy causes fetal alcohol syndrome […] Alcohol consumption during pregnancy causes FAS/FASD, and there is no safe level of consumption and no safe time. […] Binge drinking plus the large number of unplanned pregnancies (about half, by some estimates) in this country is a recipe for disaster, Miranda said, since many women may consume alcohol without being aware of their pregnancy. […] We often say that FAS is a completely preventable disease, but while in theory that’s true, the actuality is that it’s not, Miranda added. […] There are a number of other factors that may play a role in decreasing the risk for fetal alcohol syndrome. […] Alcohol consumption by an intimate partner can make it more difficult to quit during pregnancy, particularly if alcohol consumption patterns are associated with domestic violence. […] A more appropriate message is that both men and women should consider abstaining from alcohol before and during pregnancy. […] Considering that about 10 percent of women report drinking during their pregnancies, this number makes sense.
