A learning disability (LD) is a neurological disorder that affects the brain's ability to receive, process, store and respond to information. The term learning disability is used to describe the seeming unexplained difficulty a person of at least average intelligence has in acquiring basic academic skills. These skills are essential for success at school and work and for coping with life in general. LD is not a single disorder. It is a term that refers to a group of disorders. LD is a disorder that affects people's ability to either interpret what they see and hear to link information from different parts of the brain. These limitations can show up in many ways: as specific difficulties with spoken and written language, co-ordination, self control or attention. Typical learning difficulties include dyslexia, dyscalculia and dysgraphia -- often complicated by associated disorders such as attention deficit/hyperactivity disorder. This book brings together leading research in the field.
