How can we screen for autism early? We can use a tool called the Clancy Behavior Scale (CBS). Simply put, if a child exhibits 7 or more of the following 14 behaviors, parents need to take the child to a professional facility immediately. These 14 items are: 1. not easy to mix and play with others; 2. hear but not hear, as if deaf; 3. teach him to learn something, he strongly resists such as refusing to imitate, talk or do actions; 4. ignore the danger; 5. can not accept changes in daily habits; 6. gesture to express needs; 7. inexplicable laugh; 8. do not like to be hugged; 9. constantly move, can not sit, too much activity; 10. Does not look at each other’s faces and avoids eye contact; 11. Excessive preference for certain objects; 12. Prefers to spin things; 13. Repeatedly and repeatedly does some strange movements or plays; 14. Is indifferent to the surrounding. As more and more is known about autism, some early signs have been identified, such as: the child does not look at others’ faces and smile at 4 months of age; at 6 months of age, there is no obvious expression of laughter or happiness; at 12 months of age, there is no response to calling the child’s name, no yapping, no interactive gestures (pointing, waving, showing you things, etc.); at 16 months of age, the child does not pronounce single sounds. At 24 months of age, he does not speak more than 2 words. Any regression in language development at any age, where a child does not say what he or she used to say, should be of great concern to parents.
