Recently, I've been feeling unwell. My face has been pale, and I don't have an appetite for dinner. I've been experiencing nausea accompanied by vomiting again. What are the manifestations of intellectual disability in an 8-year-old?
Doctor's answer:
Children with intellectual disabilities often exhibit the following early signs: difficulties in feeding during infancy. Infants with intellectual disabilities typically show early symptoms of difficulty sucking milk. They never suck effectively and are prone to spitting out milk. This indicates that their nervous system will be affected in the future, leading to intellectual impairments. Many children have delayed language development, especially in concrete words, particularly in inferential reasoning. Their academic performance in learning-related skills is often higher than that of typical children.
