The most common, most easily recognized and probably the most researched single condition causing learning disability is Down's syndrome. Dr. Carr has followed the lives of a population-based cohort of Down's syndrome subjects from birth to early adulthood. This volume, based on extensive interviews and questionnaires that focus on fundamental issues of development and upbringing, details particularly the development of study groups between the ages 11 and 21 with a longitudinal perspective reference to earlier years as appropriate. Dr. Carr investigates a wide range of factors from behavior, discipline and independence to effects on the family and the provision of help from services. The collection of this unique data spanning the first twenty-one years of life enables Dr. Carr to offer discussion and advice that will be of international relevance and an invaluable reference for clinical psychologists, social workers and all others concerned with the care, health and well-being of Down's syndrome individuals and their families.
