Book excerpt: Understanding Fetal Alcohol Spectrum Disorder (FASD) is a useful introduction to the most common non-genetic learning disability, which is caused by alcohol consumption during pregnancy. Written by two FASD experts, it describes how alcohol can harm the foetus and disrupt development, and explains how FASD affects individuals at different stages of their lives. With the aid of simple, illustrative diagrams, photographs and charts, it shows how you can identify FASD and gives guidance on how mothers at risk can be helped. It also provides advice for parents or carers on how children, young people and adults with FASD can be best supported. Accessible and informative, this is the essential guide to FASD for social workers, family placement teams, child protection workers, foster carers, adoptive parents, midwives and teachers.
