There are very few physicians who are trained, or inclined, to diagnose Fetal Alcohol Spectrum Disorders (FASD) and there is no national diagnostic data collection mechanism for FASD or mandatory reporting of FASD and its subset diagnoses. As such, the true incidence of FASD is not precisely known and appears to be grossly under-diagnosed. Therefore, it is necessary to approach the subject from other avenues.
Inability to predict consequences, impulsivity, high potential for alcohol addiction and a hormone driven twitch in the kilt are a dangerous combination. These individuals are less likely to get proper prenatal care, admit to alcohol consumption (let alone accurately admit the quantity and frequency), or maintain proper nutrition during pregnancy. Many of these babies with FASD will never be diagnosed but will continue the cycle.
