Patient's question:
My child often speaks some words unclearly and doesn't listen to the teacher's lessons in kindergarten. He doesn't learn Pinyin well from children's songs and always forgets after learning. Is there a problem with his intelligence? He seems quite normal in other aspects. I want to know what are the symptoms of intellectual disability. What are the symptoms of intellectual disability?Doctor's answer:
Mental retardation (MR) refers to a condition where a child's intellectual and motor development during the growth period is significantly higher than that of normal children of the same age, making it difficult to adapt to the objective environment. Infants with mental retardation may exhibit the following symptoms: ① Abnormal crying: It may take repeated or sustained stimulation to elicit crying, or the crying may be sharp or weak. ② Excessive deep sleep that is difficult to awaken. ③ Infants who cannot hold their heads up at 100 days or have difficulty turning their heads; their eyes may continuously turn inward or outward. ④ Smiling only at 3–4 months, with stiff expressions that lack natural smiles by 6 months. ⑤ Continued fixation on and playing with hands at 6 months.
