As per IDEA, name a serious emotional disturbance.

Under the Individuals with Disabilities Education Act (IDEA), a serious emotional disturbance is specifically defined, and schizophrenia is included within this definition. Serious emotional disturbances encompass various conditions that significantly impact a student's functioning in educational settings, and schizophrenia is characterized by profound disruptions in thought processes, perceptions, emotional responsiveness, and behavior.

In contrast, while attention-deficit/hyperactivity disorder (ADHD), anxiety disorder, and obsessive-compulsive disorder (OCD) can also affect a student's emotional and social functioning, they do not fall under the same classification as serious emotional disturbances by the IDEA guidelines. ADHD is primarily a neurodevelopmental disorder, whereas anxiety disorders and OCD are classified under anxiety and obsessive-compulsive and related disorders, respectively.

In summary, schizophrenia is specifically acknowledged as a serious emotional disturbance in the context of IDEA, highlighting the severity and specific nature of its impact on educational performance and emotional health.
