About Fetal Alcohol Spectrum Disorders

Alcohol can harm your baby at any stage during a pregnancy. That includes the earliest stages, before you even know you are pregnant. Drinking during pregnancy can cause a group of conditions called fetal alcohol spectrum disorders (FASDs). Children who are born with FASD can have a mix of problems, such as medical, behavioral, educational, and social problems. The kinds of problems they have depend on which type of FASD they have. The problems could include :

  • Abnormal facial features, such as a smooth ridge between the nose and upper lip
  • Small head size
  • Shorter-than-average height
  • Low body weight
  • Poor coordination
  • Hyperactive behavior
  • Difficulty with attention and memory
  • Learning disabilities and difficulty in school
  • Speech and language delays
  • Intellectual disability or low IQ
  • Poor reasoning and judgment skills
  • Sleep and sucking problems as a baby
  • Vision or hearing problems
  • Problems with the heart, kidneys, or bones

Fetal alcohol syndrome (FAS) is the most serious type of FASD. People with fetal alcohol syndrome have facial abnormalities, including wide-set and narrow eyes, growth problems and nervous system abnormalities.

Diagnosing FASD can be hard because there is no medical test, like a blood test, for it. The health care provider will make a diagnosis by looking at the child's signs and symptoms and asking whether the mother drank alcohol during pregnancy.

FASDs last a lifetime. There is no cure for FASDs, but treatments can help. These include medicines to help with some symptoms, medical care for health problems, behavior and education therapy, and parent training. A good treatment plan is specific to the child's problems. It should include close monitoring, follow-ups, and changes when needed.

Certain "protective factors" can help reduce the effects of FASDs and help people who have them reach their full potential. They include:

  • Diagnosis before 6 years of age
  • Loving, nurturing, and stable home environment during the school years
  • Absence of violence around them
  • Involvement in special education and social services

There is no known safe amount of alcohol during pregnancy. To prevent FASDs, you should not drink alcohol while you are pregnant, or when you might get pregnant.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Fetal Alcohol Spectrum Disorders

68 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
