Which condition is characterized by impaired social skills and communication abilities?

The condition characterized by impaired social skills and communication abilities is Autism Spectrum Disorder (ASD). This developmental disorder is marked by challenges in social interaction, verbal and nonverbal communication, and repetitive behaviors or restricted interests. Individuals with ASD often find it difficult to interpret social cues, engage in typical back-and-forth conversations, and understand the social dynamics of various situations. This can lead to difficulties in forming relationships and participating in social activities, which are core aspects of the impairment associated with this disorder.

In comparison, Attention Deficit Hyperactivity Disorder primarily affects attention and impulse control, and while it can influence social interactions, it does not inherently impair social communication skills in the same way as ASD. Asperger's Syndrome, which is considered a part of the Autism Spectrum, has more specific characteristics and generally implies higher functioning with less pronounced communication challenges, though it still shares some traits with ASD. Generalized Anxiety Disorder involves excessive worry and anxiety that can affect social situations, but it does not directly pertain to the impairment of social skills and communication abilities as seen in ASD. Therefore, Autism Spectrum Disorder is the most appropriate choice for this question.
