I. Introduction to Autism
Autism Spectrum Disorder (ASD), also known as autism, is a group of neurodevelopmental disorders that affect normal brain function. These issues lead to abnormalities in speech, communication, social awareness, and imagination, thereby reducing the quality of life for individuals with autism. According to the latest data from the U.S. Centers for Disease Control and Prevention (CDC), the 2020 report indicates that the prevalence of Autism Spectrum Disorder (ASD) in the United States is approximately 1 in every 54 children. This statistic is based on the "Autism and Developmental Disabilities Monitoring Network" (ADDM Network), which conducts surveys among children across multiple states in the U.S. Additionally, the incidence of this condition is higher in boys than in girls. Research shows that symptoms of autism become more apparent by the age of 3, and early intervention can help improve dependency and quality of life for individuals with autism.
II. Common Symptoms
Individuals with autism may exhibit various social, communication, and behavioral characteristics. Below are some common signs and symptoms:
1. Social Interaction Difficulties
• Limited or infrequent eye contact
• Failure to respond to their name
• Avoidance of hugs or discomfort with physical closeness
• Rarely sharing interests or emotions
• Difficulty sustaining conversations
• Trouble adjusting behaviors to social contexts
• Challenges engaging in imaginative play or making friends
2. Communication Challenges
• Delayed speech development or lack of speech
• Unusual tone or rhythm in speaking
• Facial expressions or gestures that mismatch verbal content
• May exhibit echolalia (repeating phrases or words)
• Poor nonverbal communication skills (e.g., gestures, eye contact)
• Delayed speech and communication development in young children
3. Stereotyped and Repetitive Behavioral Patterns
• Repetitive actions, words, or phrases
• Intense, persistent focus on specific topics
• Distress over changes to routines or environments
• Hypersensitivity to sensory input (e.g., light, sound, clothing textures, temperature)
4. Other Associated Features
• Limited expressiveness and possible unawareness of surroundings
• Narrow interests, which may lead to compulsive behaviors
• Neurological impacts (e.g., gross motor skill difficulties)
• Poor response to therapies; some individuals may experience seizures
III. Age-Specific Diagnostic Tool Guidelines (Latest U.S. Version)
Due to potential challenges in accessing face-to-face consultations with licensed therapists, many organizations provide online screening tools to help identify traits associated with Autism Spectrum Disorder. These tools are not substitutes for a formal diagnosis but may serve as preliminary screening methods. Below are testing approaches tailored to different age groups:

Key Symbols
- Gold-standard: ADI-R+ADOS combo >90% accuracy
- Positive screen: M-CHAT requires follow-up within 2 weeks
- Adult threshold: AQ≥32 suggests clinical evaluation
IV. Conclusion
While online assessments may help identify potential autism-related traits, they cannot replace a professional medical diagnosis. If you suspect that you or a family member might be on the autism spectrum, it is essential to seek evaluation from licensed healthcare professionals. Early intervention is critical for improving long-term outcomes, and timely action can lead to better results. We hope this article provides valuable insights and encourages further exploration and understanding of Autism Spectrum Disorder.
