What is the most common developmental disorder that results in limitations of mental functioning?

The choice of Intellectual Developmental Disorder is accurate because it specifically refers to a range of conditions characterized by limitations in adaptive functioning, intellectual functioning, and overall cognitive abilities that emerge during the developmental period. This disorder can manifest through challenges in areas such as reasoning, problem-solving, planning, abstract thinking, and academic learning.

Intellectual Developmental Disorder is commonly diagnosed in childhood and has an impact on daily living skills, making it distinct from other developmental disorders which may not necessarily involve limitations in intellectual functioning. For instance, Attention Deficit Hyperactivity Disorder primarily involves attention and impulse control issues rather than cognitive limitations. Autism Spectrum Disorder encompasses a broader range of challenges related to social communication and behavior but does not inherently involve intellectual impairment, as individuals can possess various cognitive capabilities. Learning Disabilities, on the other hand, affect specific areas of learning (like reading or math) without necessarily impacting overall intellectual functioning.

Thus, Intellectual Developmental Disorder stands out as the most prevalent condition directly linked to limitations in mental functioning during development.
