In this book the author explores the impact of various genetic syndromes on children's lives. She describes conditions such as Down's Syndrome, Williams Syndrome, Angelman Syndrome and Prader-Willi Syndrome, discussing their practical implications for daily life and the physical and behavioural symptoms associated with them. An accessible introduction to genetics precedes detailed investigations of the ways in which young people are affected by genetic conditions: the extent to which their behaviour is determined, the difficulties they face and the ways in which they can achieve independence and fulfilment. Case studies of individuals the author has worked with add to the personal approach of this book and help to ensure 'the child behind the syndrome' is always visible. Health and education professionals, parents and carers will find this readable and informative book invaluable in understanding the worlds of those who live with a genetic syndrome linked to an intellectual disability.
