Which condition is defined by impairments in social interactions, communication, and restricted interests?

The condition characterized by impairments in social interactions, communication, and restricted interests is Autism Spectrum Disorder (ASD). ASD is a neurodevelopmental disorder that manifests in a range of symptoms and severity. Individuals with ASD often struggle with understanding social cues, engaging in reciprocal conversations, and may have difficulties interpreting nonverbal communication. This can lead to challenges in forming and maintaining relationships.

Additionally, restricted interests are a hallmark of ASD, where individuals may focus intensely on specific topics or hobbies, sometimes to the exclusion of developing other skills or interests. This combination of symptoms creates a distinct profile that sets ASD apart from other neurodevelopmental and mental health disorders.

While neurodevelopmental disorders is a broader category that includes ASD, it does not specifically capture the unique features of social interaction difficulties and restricted interests. Attention Deficit Hyperactivity Disorder (ADHD) is focused primarily on attention regulation and hyperactivity, and does not encompass the social and communication deficits seen in ASD. Anxiety Disorders involve excessive fear and anxiety but do not specifically highlight the communication and social interaction impairments that are core to ASD. Therefore, ASD is the most accurate response to the question.
