Intellectual disability is a condition that affects a person’s cognitive abilities and adaptive functioning. People with intellectual disabilities may have difficulty learning and processing information, communicating effectively, and performing daily tasks independently. There are several different types of intellectual disabilities, each with their own unique characteristics.

In this blog, we’ll explore some of the most common types of intellectual disabilities.

1. Down Syndrome

Down syndrome is one of the most well-known types of intellectual disabilities. It is caused by an extra copy of chromosome 21 and affects approximately 1 in 700 babies born in the United States. People with Down syndrome typically have distinct physical features and may have developmental delays and intellectual disabilities of varying degrees.

2. Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects social interaction, communication, and behavior. People with ASD may have difficulty with verbal and nonverbal communication, have trouble understanding social cues, and engage in repetitive behaviors. The severity of ASD can vary widely from person to person.

3. Fetal Alcohol Spectrum Disorder

Fetal Alcohol Spectrum Disorder (FASD) is a group of conditions that can occur in a person whose mother drank alcohol during pregnancy. It can cause intellectual disabilities, as well as physical and behavioral problems. The severity of FASD can vary depending on the amount and timing of alcohol exposure during pregnancy.

4. Intellectual Disability of Unknown Cause

In some cases, the cause of intellectual disability is not known. These cases are referred to as intellectual disability of unknown cause. It is estimated that up to 50% of cases of intellectual disability fall into this category.
