A girl with normal milestones spend her time seeing her own hand, do not interact with others, what is the diagnosis
**Core Concept**
The question describes a child who is exhibiting self-directed behavior, lack of social interaction, and is preoccupied with her own hand, indicating a possible developmental disorder. This behavior is characteristic of a child with autism spectrum disorder (ASD), a neurodevelopmental disorder that affects communication, social interaction, and behavior.
**Why the Correct Answer is Right**
This child's behavior is consistent with the diagnostic criteria for ASD, particularly the symptoms of restricted and repetitive patterns of behavior, interests, or activities. The child's preoccupation with her own hand may be a stereotypic behavior, which is a common feature of ASD. The lack of social interaction and eye contact further supports this diagnosis. The child's normal milestones suggest that the disorder may have manifested later in development.
