Which of the following disabilities is covered by IDEA 2004?

IDEA 2004, or the Individuals with Disabilities Education Improvement Act, specifically outlines the categories of disabilities that qualify children for special education services. Autism is one of the recognized categories under this act, which provides guidelines for educational support for children with this developmental disorder.

Autism can significantly impact social communication and behavior, which can hinder a child's ability to thrive in a traditional educational setting. As such, under IDEA, schools are mandated to create an Individualized Education Program (IEP) for qualified students with autism, ensuring that they receive tailored educational supports and resources to facilitate their learning.

On the other hand, options like Social Media Disorder and Substance Abuse Disorder are not recognized as educational disabilities under IDEA, primarily because they do not fit within the established categories that qualify for special education services. Post-Traumatic Stress Disorder, while it can have significant implications for a child's functioning, is also not explicitly categorized as a disability under IDEA, though accommodations may be made under general educational laws or Section 504 of the Rehabilitation Act if it substantially limits a child's educational performance.
