Speech and Language Development and Intervention in Down Syndrome and Fragile X Syndrome (CLI)

Spotlighting two of the most prevalent and most researched genetically based disabilities--Down syndrome and Fragile X syndrome--this cutting-edge text clarifies the distinct speech and language issues associated with each disorder and helps readers conduct individualized assessment and intervention. An essential upper-level textbook and an invaluable professional reference, this book gives readers the up-to-date research and clinical insight they need to

• fully understand both disabilitiesâ "the behaviors, characteristics, genetics, and treatments associated with each
• see how speech and language develop across the lifespan, from infancy to adulthood
• apply principles of effective assessment with people from every age group
• use specific interventions to support key aspects of speech and language development
• tailor assessment and intervention to an individual's communicative needs and abilities
• tune into the family's perspective and encourage their ongoing involvement
• examine other disorders by using this research as a model for future practice

Authoritative contributions from more than 15 leading experts prepare readers for effective clinical practice, and the "directions for research" sections throughout the book help researchers shape future studies and move the field forward.

A necessary resource for SLPs, pediatricians, AAC specialists, and early interventionists, this definitive volume is key to supporting the communicative competence of people with Down syndrome and Fragile X syndrome at every stage of life.

In Memory of Marc E. Fey

The field of communication sciences lost a remarkable leader when Marc Fey passed away on September 12, 2023. At Brookes, we will remember him as the dedicated Co-Series Editor of the Communication and Language Intervention (CLI) book series, which he helped direct and expand for many years. Marc was not only a series editor but also a volume editor/author. One of those titles, Treatment of Language Disorders in Children, now in its second edition and slated for a third, has become a classic text for speech-language pathologists, for its balanced examination of interventions for emerging communication and language as well as more advanced language and literacy. A strong supporter of evidence-based practice, Marc brought his passion for research and commitment to well-designed intervention studies to the selection process for the CLI series. Those books benefited from his keen editorial and writing skills. Our staff who had the pleasure of working with him will remember many enjoyable moments at CLI Board meetings and his collaborative, encouraging leadership. His legacy will live on in the volumes he helped to envision and create for the field, and the difference he made in the lives of so many children with speech and language disorders.
