Learning Disability is a classification including several areas of functioning in which a person has difficulty learning in a typical manner, usually caused by an unknown factor or factors.
While learning disability, learning disorder and learning difficulty are often used interchangeably, they differ in many ways. Learning disability refers to significant learning problems in an academic area. These problems, however, are not enough to warrant an official diagnosis. Learning disorder, on the other hand, is an official clinical diagnosis, whereby the individual meets certain criteria, as determined by a professional (psychologist, pediatrician, etc.) The difference is in degree, frequency, and intensity of reported symptoms and problems, and thus the two should not be confused. When the term “learning disabilities” is used, it describes a group of disorders characterized by inadequate development of specific academic, language, and speech skills. Types of learning disabilities include reading disability (dyslexia), mathematics disability (dyscalculia) and writing disability (dysgraphia).
