Asperger Syndrome

Asperger syndrome is a neurodevelopmental disorder characterized by marked deficits in social interaction and restricted, repetitive patterns of behavior. This syndrome emerges in early childhood and persists throughout the individual’s life. It was first described by Hans Asperger in 1944 and later classified within the group of pervasive developmental disorders. Previously recognized as a distinct diagnosis in DSM-IV, Asperger syndrome is now evaluated within the broader category of autism spectrum disorder under DSM-5.

In Asperger syndrome, language development does not show clinically significant delay. Speech is fluent, but individuals experience difficulties with the pragmatic aspects of communication, such as sustaining reciprocal interaction and using social cues during conversation. These individuals typically have narrow and intense areas of interest and frequently exhibit repetitive behaviors. Clumsiness, coordination difficulties, and motor awkwardness are common. Additionally, lack of eye contact and limited use of gestures and facial expressions stand out as nonverbal communication impairments.

Asperger syndrome shares many features with high-functioning autism. However, unlike autism, language development is normal and intellectual functioning is typically above average. Nevertheless, establishing clear diagnostic boundaries between the two conditions is challenging. Asperger syndrome may also be confused with clinical presentations such as social communication disorder, attention deficit hyperactivity disorder, and obsessive-compulsive disorder. In differential diagnosis, particular attention should be paid to pronounced motor clumsiness and the presence of specialized interests.

Asperger syndrome is more frequently observed in males than in females, with a male-to-female ratio reported at approximately 10:1. The prevalence in the general population ranges from 3.6 to 7 per 1,000. Although symptoms typically emerge in early childhood, diagnosis is most often made during school age or later.
