Intellectual Disability Overview

Intellectual Disability Overview 

In this course, you will learn the definition of intellectual disability (ID) how a person with ID is diagnosed and evaluated, and some of the causes and signs of ID. You will learn how to distinguish between facts and myths, find out about the range of educational and employment opportunities for individuals with ID, and learn some tips and strategies that you can use in your own career. This course is appropriate for professionals that work in the field of developmental disabilities and anyone who provides services to individuals with ID. Intellectual disability (ID) as it is defined in the Diagnostic and Statistical Manual of Mental Disorders – Fifth Edition or DSM-5™ (the International Classification of Diseases or ICD-10 uses the term, “intellectual developmental disorder”) was formerly known as mental retardation, and is characterized both by below-average cognitive ability and significant limitations in the ability to adapt to and carry out everyday tasks. Many myths and stereotypes abound - even in the 21st century - that reinforce cause for ridicule and bullying, present individuals as forever children, accentuate negative social behavior, and emphasize disparity. These prejudicial beliefs create barriers for individuals with intellectual disability to be viewed as valued members of our communities, as well as to pursue and lead fulfilling lives.
