Examining eye blinks can identify children with probable fetal alcohol syndrome in alcohol-exposed children, U.S. researchers said.
The study, published in Alcoholism: Clinical & Experimental Research, found children lacking the distinctive facial effects linked to fetal alcohol syndrome could still be identified as having alcohol-related neurodevelopmental disorder using a test called eyeblink conditioning.

The link between eyeblink conditioning impairment by alcohol exposure during pregnancy has already been found in animal studies, Jacobson explained.
