What physical feature is associated with fetal alcohol syndrome in children?

Children with fetal alcohol syndrome (FAS) often exhibit smaller than average brain size, which is a critical characteristic linked to the condition. This brain size reduction is associated with various structural abnormalities in the brain that can lead to cognitive impairments and developmental delays. The smaller brain size is a direct result of prenatal exposure to alcohol, which disrupts normal brain development during critical periods.

In addition to the reduced brain size, children with this syndrome may also exhibit a range of other physical and neurological issues, including facial abnormalities, growth deficiencies, and potential learning difficulties. However, the defining feature of reduced brain size makes it a central focus when diagnosing fetal alcohol syndrome in children. Understanding this relationship helps healthcare providers recognize the implications of prenatal alcohol exposure on child development and the importance of prevention strategies.
