Fetal alcohol syndrome in adults is more common than most people realize. Usually, the condition is never diagnosed during childhood, and that is exactly what makes it challenging to navigate. If you, or someone you know are dealing with this syndrome, don’t worry, you’re not alone. For families, caregivers, and healthcare providers in Los Angeles and across California, understanding what fetal alcohol syndrome looks like in adulthood is a critical first step toward getting the right help.
What Is Fetal Alcohol Syndrome (FAS)?
Fetal alcohol syndrome (FAS) is a permanent neurological and developmental disorder caused by exposure to alcohol. It occurs when a pregnant woman consumes alcohol while pregnant. This can affect the development of the baby and result in physical and mental defects of the child. FAS is a chronic condition that can affect people well into adulthood.
Prenatal alcohol exposure is a leading preventable cause of birth defects and neurodevelopmental deficits in the United States, and the effects can appear at any time during childhood and last a lifetime. According to the NIAAA, recent prevalence studies estimate that approximately 1 to 5 percent of U.S. first-grade children have FASD, which suggests that many adults are left undiagnosed.
Physical Signs and Symptoms of Fetal Alcohol Syndrome in Adults
FAS Facial Features in Adults
One of the most recognizable features of fetal alcohol syndrome in adults is the physical appearance, especially the face. Some of the facial features of FAS may become less noticeable with age, but many are clearly apparent in adults and may be important clues to a late diagnosis. Classic fas facial characteristics include:
- Smooth philtrum (no or flattened ridges between the nose and upper lip)
- Thin upper lip
- Small eye openings (short palpebral fissures)
- flat midface and flat cheekbones
- Microcephaly (a small head size)
- Small stature
Fetal Alcohol Syndrome Eyes in Adults
The eyes are one of the most clinically important physical markers of FAS. In adults, fetal alcohol syndrome eyes are usually the result of restricted orbital growth during prenatal development, which causes small eye openings. In adults, poor vision can also lead to problems such as tracking moving objects and sensitivity to light. The eye effects are caused by alcohol disrupting early development of the eye and brain, and can last a lifetime, even getting worse if not properly managed.
Some adults with FAS have strabismus (crossed eyes) or problems with visual processing that are neurological, not structural, beyond the eye openings themselves.
Other Physical Features
Signs of fetal alcohol syndrome in adults may also include organ abnormalities affecting the heart, kidneys and bones in addition to the face. They are collectively known as alcohol-related birth defects (ARBD). Adults may have joint problems, hearing problems and be shorter and lighter than average.
Psychological and Behavioral Symptoms of Fetal Alcohol Syndrome in Adults
Exposure to alcohol during pregnancy leads to various cognitive and behavioral symptoms. Common symptoms of fetal alcohol syndrome in adults are:
- Learning and memory problems
- Poor impulse control
- Difficulty with abstract thinking
- Attention difficulties
What Causes Fetal Alcohol Syndrome?
FAS has one cause: alcohol consumed during pregnancy. Alcohol is passed through the bloodstream to the fetus through the umbilical cord, and the baby does not metabolize alcohol in the same way an adult does. It interferes with the normal development of the fetus, particularly the brain and central nervous system.
Critically, there is no safe amount of alcohol that can be consumed during pregnancy. Damage to a developing baby can happen at any point, and all alcohol can cause FAS. Risk factors that increase the risk of a child being born with FAS include heavy or binge drinking during the first trimester, poor maternal nutrition, lack of prenatal care and co-use of tobacco or other substances.
Prenatal alcohol exposure
FAS can occur with any level of alcohol use during pregnancy. All alcohol types, whether beer, wine, ciders or hard liquor carry the same risk. The risk is greater in the first trimester, when the brain and face are developing most rapidly, but any alcohol exposure can cause permanent harm.
Alcohol use disorder
For women living with alcohol use disorder, the risk of prenatal alcohol exposure is particularly high. In California, state public health campaigns have long emphasized complete alcohol abstinence during pregnancy, yet alcohol use disorder among women of childbearing age remains a significant concern in communities across Los Angeles County. If you are a woman struggling with alcohol dependence and planning a pregnancy, seeking alcohol addiction treatment in Los Angeles before or during pregnancy is one of the most impactful steps toward preventing FAS in future children.
How Fetal Alcohol Syndrome Affects Adults
The effects of FAS in adults span nearly every area of daily life. Adults with FAS often need support as they try to navigate housing, employment, transportation, and money management. Many children with fetal alcohol syndrome have problems in school but do receive an education. A major challenge on the job is consistency of employment. There are memory problems, difficulty following multi-step instructions, and problems with impulse control. Socially they are easily manipulated or exploited due to poor social judgment.
Adults with FASDs generally have difficulty sustaining employment or living independently in their communities. Legal troubles are also disproportionately common: teenagers and adults with FASDs are at higher risk for encounters with police, authorities, or the judicial system as they have difficulty controlling anger and frustration, combined with problems understanding the motives of others, result in many people with FASDs being involved in violent or explosive situations.
Mental Health Challenges and Co-Occurring Conditions
Adults with fetal alcohol syndrome have much higher rates of mental health disorders. Studies have demonstrated a higher risk of cognitive disorders such as memory loss, mental illness or psychological disorders in people with FASDs. Attention-deficit/hyperactivity disorder (ADHD), conduct disorder, substance use disorder, depression and anxiety are among the most common co-occurring diagnoses.
The relationship of FAS to substance use disorder has a special importance. Studies suggest that more than one third of people with FASDs have had problems with alcohol or drugs, with over half of them requiring inpatient treatment. The challenges are compounded in a place like Los Angeles where adults with FAS who become addicted need specialized, integrated care. Dual diagnosis treatment that address co-occurring mental health and substance use conditions simultaneously are especially well-suited to this population.
How Is Fetal Alcohol Syndrome Diagnosed in Adults?
Diagnosis in adulthood is possible but challenging. There is no single test for FAS, and because many adults were never flagged as children, their medical history may not include documentation of prenatal alcohol exposure.
Clinicians assessing adults for FAS typically look for a combination of the following:
- Physical features consistent with FAS (particularly the facial triad: smooth philtrum, thin upper lip, small eye openings)
- Evidence or strong likelihood of prenatal alcohol exposure
- Growth deficiencies
- Documented central nervous system impairment: either structural (small head size, brain abnormalities on imaging) or functional (significant deficits in cognition, memory, attention, or behavior)
Treatment and Support for Adults With Fetal Alcohol Syndrome
There is no cure for fetal alcohol syndrome in adults, but targeted treatment and support can greatly improve functioning and quality of life. Good approaches are multidisciplinary and address the entire spectrum of challenges a person is facing.
- Medication management
- Cognitive-behavioral therapy (CBT)
- Occupational therapy
- Case management and supported living
- Substance use treatment
For those whose substance use has become severe, beginning with alcohol detox under medical supervision is an important first step before transitioning into longer-term therapeutic work.
Positive factors that improve outcomes for adults with FASDs include being diagnosed early, involvement in special education and social services, living in a stable and nurturing home, and absence of domestic violence. Even when an early diagnosis was missed, connecting with the right support system in adulthood can still meaningfully change the trajectory of someone’s life.
Can Adults With Fetal Alcohol Syndrome Live Independently?
The level of independence for people with fetal alcohol syndrome varies greatly and depends on the severity of the syndrome and the level of support available. Some people with milder presentations of the FASD spectrum are able to live semi-independently with minimal assistance. Some need constant, structured help with every part of daily life.
For those whose independence is also complicated by addiction, The House of Life – a luxury rehab in Los Angeles – offers a high level of individualized, person-centered care that addresses both the neurological realities of FAS and the challenges of substance use recovery, providing the kind of comprehensive environment where meaningful progress becomes possible.
When to Seek Professional Help
If you or someone you love shows signs of fetal alcohol syndrome in adults it is worth pursuing a formal evaluation. And the same is true if there is known or suspected prenatal exposure to alcohol.
Finding a neuropsychologist, developmental specialist, or addiction medicine provider familiar with FASD is an important first step. The sooner the diagnosis is made, the sooner appropriate accommodations and interventions can be put in place. For those who need more structured, immersive care, The House of Life offers residential treatment in Los Angeles with 24/7 support, particularly useful for FAS adults who struggle to handle daily life independently.
