Intellectual disability (ID) is a developmental disability that affects a person’s ability to learn, think, and reason. People with ID have a lower IQ than most people, and they may also have difficulty with adaptive behavior, which is the ability to perform everyday tasks such as self-care, communication, and independent living.
Causes of Intellectual Disability
The causes of intellectual disability are varied and can be genetic, environmental, or a combination of both. Some of the most common causes of ID include:
Fragile X syndrome
Autism spectrum disorder
Infections during pregnancy or childbirth
Exposure to toxins
Signs and Symptoms of Intellectual Disability
The signs and symptoms of intellectual disability can vary depending on the severity of the disability. Some common signs and symptoms include:
Slow development of language and motor skills
Difficulty learning new things
Difficulty with problem solving

Diagnosis of Intellectual Disability
A diagnosis of intellectual disability is made by a team of professionals, including a doctor, a psychologist, and a special education teacher. The team will assess the person’s IQ, adaptive behavior, and other factors to make a diagnosis.
Treatment for Intellectual Disability

Supportive services such as respite care and homemaking assistance
