With sections on diagnosis, symptoms and treatment, as well as discussions of various emotional and behavioural considerations, this guide covers all aspects of Fragile X syndrome, its implications, and the possibilities open to families affected by it. It demonstrates how, with the right therapies, progress can be made and emphasises how music can be used effectively to promote communication, interaction, fine motor skills and responsiveness in children with the condition. This is an essential reference tool for families of individuals with Fragile X syndrome, as well as therapists and healthcare professionals who are unfamiliar with the condition and are looking to find out more.
