FAS indicators in adults are similar to those in children, although they are often more pronounced in adults.

1. What Are the Signs and Symptoms of FAS in
Adults?
The signs and symptoms of Fetal Alcohol Syndrome in adults can
range from mild to severe. FAS indicators in adults are similar to
those in children, although they are often more pronounced in
adults.
Signs and symptoms of FAS in adults can include:
Growth Deficiencies
Adults with Fetal Alcohol Syndrome may have a smaller head
circumference than average, as well as height and weight below
the normal range.
Facial Abnormalities
Those with Fetal Alcohol Syndrome often have distinctive facial
features, including small eyes, a thin upper lip, or a smooth groove
between the nose and upper lip, which is called the philtrum.
Someone with FAS may have all or none of these signs, as well as
other irregularities in their facial features.
Intellectual Disabilities
Fetal Alcohol Syndrome often results in intellectual disabilities.
These disabilities can affect cognition as well as overall academic
or occupational achievement due to challenges with learning and
memory. Those with Fetal Alcohol Syndrome often experience
difficulties learning and retaining new information, facts, details,
and applying knowledge to practical situations.

2. Behavioral and Emotional Problems
Adults with Fetal Alcohol Syndrome may experience difficulties with
social interactions as well as challenges with emotional and
behavioral regulation. FAS may cause problems with impulse
control and poor judgment which can lead to interpersonal,
occupational, or legal ramifications.
Increased Risk for Mental Health Disorders
Individuals with FAS are at increased risk for mental health
conditions such as depression, anxiety, substance abuse, or other
mental health disorders. Early intervention is recommended for
children with FAS, but adults who have not been diagnosed or
treated benefit from interventions as well.
Treatment for Adults With Fetal Alcohol Syndrome
Adults with Fetal Alcohol Syndrome are at higher risk for addiction
and co-occurring disorders. If you or a loved one with FAS is
experiencing signs or symptoms of addiction as well as mental
health disturbances, help is available.
