Fetal Alcohol Spectrum Disorder (FASD) is a spectrum of life-long disorders caused by prenatal alcohol exposure. The adverse effects of FASD include cognitive, behavioral, emotional, physical, and adaptive functioning deficits. Since the deficits and symptoms of FASD can have a deleterious impact on the individual's overall daily functioning over the lifespan, assistance from a qualified mental health professional is often required. While FASD can be potentially debilitating, long-term positive outcomes have been associated with early intervention and diagnosis provided by adequately trained mental health professionals. This article provides the reader with an introductory overview of FASD and its implications for mental health treatment professionals, training recommendations, and suggestions for future research.
