Asperger's syndrome is a developmental disorder that was previously considered a distinct diagnosis but is now classified under autism spectrum disorder (ASD). It is characterized by difficulties in social interaction and nonverbal communication, alongside restricted and repetitive patterns of behavior and interests. People with Asperger's typically have average or above-average intelligence and do not have significant delays in language development, but they may struggle with understanding social cues, body language, humor, and sarcasm. They often have intense, narrow interests and may display repetitive behaviors or routines

. The term Asperger's syndrome has been retired in diagnostic manuals like the DSM-5 and ICD-11, and individuals who would have previously been diagnosed with Asperger's are now diagnosed with level 1 ASD, which is considered a "high-functioning" form of autism without intellectual or language impairment

. Common symptoms include:

• Difficulty with social interactions and understanding emotions
• Challenges in nonverbal communication such as gestures and facial expressions
• Speech that may sound unusual (e.g., flat, monotone)
• Obsessive focus on specific topics or interests
• Sensory sensitivities (to lights, sounds, textures)
• Clumsiness or motor coordination difficulties
• Resistance to changes in routine

Asperger's syndrome affects how individuals perceive and interact with the world and others, often leading to social isolation or challenges in employment and relationships. The exact causes are not fully known but likely involve genetic and neurological factors
