This third edition of Disorders of Development and Learning builds upon the superb foundation established by the previous editions while maintaining its basic text format. The first section provides information on various assessments and general management procedures. Theories of development and learning are described to provide a theoretical system for a scientific method of management. Commonly used assessment procedures from such professionals as psychologists and speech and language clinicians are examined in addition to providing information on developmental screening and early intervention. The second section of the book provides specific information about the most common developmental and learning disorders likely to be seen by the primary care clinician. Each chapter has been revised to include the most recent information available, particularly for attention deficit hyperactivity disorder. Several chapters have been added to cover some additional common causes of mental retardation.
