Overview
Intellectual disability (ID) belongs to neurodevelopmental disorders that affect children and adolescents during the developmental period. It is categorized into four subclasses that determine the need for support. This condition is characterized by impairments in both intellectual and adaptive functions. Research involving ID has found that genes that encode cognitive abilities play an essential role in its pathophysiology. An interplay of environment and genetics can cause ID, and comprehensive screening is done in these cases. More importantly, ID has existing co-morbid conditions, which makes treatment and care a challenge.
Historical Perspective
Intellectual disability traces its roots back to ancient civilizations. The Egyptians focused on treating disabilities and other ailments, while Greek and Roman Civilizations negatively viewed disability, killing those with disabilities. During the Middle Ages, intellectual disability revolved around religion and superstitions. The Church became a refuge for the individual with disabilities by providing shelter. The Restoration period associated "idiocy" and mental illness with immortality for which having a disability is a punishment. In the 17th century, John Locke differentiated intellectual disabilities from physical ones, where both mental and emotional deficits characterized intellectual disabilities. Oxford Philosopher Willis pinpointed various etiologies for a mental disability such as heredity, trauma, other diseases, and spirits. [1]
