Intellectual Disability (I.D.), generally known as ID, refers to substantial limitations in present functioning.
It begins before the age of 18 and is characterized by significantly below-average intellectual functioning, existing together with related limitations in adaptive skills.
Intellectual Disability (formerly known as mental retardation) is a neurodevelopmental disorder characterized by:
Below-average intellectual functioning (IQ ≤ 70)
Deficits in adaptive behavior (social, conceptual, practical skills)
Onset before age 18
It affects a person's ability to reason, learn, solve problems, and live independently.
These affect mental functioning and adaptive behavior (learning, communication, and daily skills).

Hemophilia – Blood doesn’t clot properly
Thalassemia – Genetic blood disorder
Sickle Cell Disease – Red blood cells become sickle-shaped and block flow
When a person has two or more disabilities together, such as intellectual disability with blindness or cerebral palsy with hearing loss.
Example: Multiple Disabilities including Deafblindness.
