What Disorders Fall Under IDD?

Understanding Intellectual and Developmental Disabilities (IDD)

In order to unravel the complexities surrounding intellectual and developmental disabilities (IDD), it is important to have a clear understanding of what IDD entails and the scope of conditions it encompasses.

What is IDD?

IDD, short for intellectual and developmental disabilities, refers to a group of conditions characterized by limitations in intellectual functioning and adaptive behavior. These disabilities manifest during the developmental period and have a lasting impact on an individual's everyday functioning and independence.

Intellectual functioning encompasses a person's ability to learn, reason, and problem-solve. Adaptive behavior, on the other hand, refers to a person's practical skills and ability to navigate everyday activities, such as communication, self-care, and social interactions.

The Scope of IDD

IDD encompasses a wide range of disorders, each with its own unique characteristics and challenges. These disorders can be broadly categorized into two main types: intellectual disabilities (ID) and developmental disabilities (DD).

Intellectual disabilities (ID) refer to conditions that primarily affect a person's intellectual functioning. Individuals with ID may have difficulties with learning, problem-solving, and understanding abstract concepts. The severity of intellectual disabilities can vary widely, ranging from mild to profound.

Developmental disabilities (DD) encompass a broader group of conditions that impact various aspects of a person's development and functioning. These conditions may affect physical, cognitive, communication, and social-emotional development. Developmental disabilities can occur alongside intellectual disabilities or independently.

To better understand the specific disorders falling under IDD, let's explore each category in more detail. Continue reading to learn about intellectual disabilities (ID) and developmental disabilities (DD), including their definitions, characteristics, causes, and common disorders associated with each category.
