Intellectual Disability
People with intellectual disabilities have learning dif-
fi culties and develop at a slower than normal rate. The 
condition is usually identifi ed at birth or in early child-
hood. Intellectual disability is not a mental illness and

fered by mental health services. However, people with 
intellectual disabilities can also experience a mental 
illness. Formerly called “mental retardation”.
Intellectualization 
A mental mechanism in which the person engages 
in excessive abstract thinking to avoid confrontation 
with confl icts or disturbing feelings.
