“…Researchers have proposed a link between prenatal alcohol exposure and infant irritability (Burd, Klug, Martsolf, & Kerbeshian 2003;Clifford, Campbell, Speechley, & Gorodzinsky, 2002;Coles & Platzman, 1993;Scher, Richardson, Coble, Day, & Stoffer, 1988) mediated by subtle neuronal dysfunctions (Kelly, Day, & Streissguth, 2000). In the most severe cases, maternal drinking leads to fetal alcohol syndrome, which is diagnosed when three criteria are met: (a) growth deficiency in both the prenatal and postnatal periods, (b) structural anomalities and/or functional deficits in the central nervous system associated with mental retardation and behavioral problems, and (c) a distinctive pattern of abnormal facial features (Sokol & Clarren, 1989).…”
