If you are not mentally retarded before adulthood, will you become mentally retarded after adulthood?
No, as long as it's not an adult and not injured, then in the end, it won't be mentally retarded, so don't worry. The following is extended information about mental retardation.

cause

(1) →→→→→ ① Brain hypoxia caused by prolonged amniotic fluid retention during clinical delivery can lead to mild mental retardation; ② Children's brain trauma (especially coma, including birth injury); ③ Children's lead poisoning and mercury poisoning (including lead dust) lead neurotoxicity → 1: The blood-brain barrier is underdeveloped. 2. Effect of lead on intracellular second messenger → Lead affects the function of brain cells by affecting adenylate cyclase and calcium ion. 3. The influence of lead on nerve cell adhesion molecules → It is found that chronic low-level lead exposure can delay the transformation of nerve cell adhesion molecules in brain tissue from fetal type to adult type, so that the development of various components in brain tissue can not be synchronized, leading to abnormal nervous system structure, electric shock (which may damage nerves, but this is rare), carelessness in practicing Qigong (which will cause continuous psychological damage) and long-term isolation from society (such as the phenomenon of "wolf child").

⑦ Mother was exposed to electromagnetic radiation, and some drugs were poisoned during pregnancy (such as sedatives and marijuana). ), 9) overuse of anesthetics during delivery, 10) malnutrition, 10) mental stimulation during pregnancy, 13) drinking and smoking in pregnant women, 13) iodine deficiency in infants (causing cretinism), 13) mother. (2 1) Child's cerebral hemorrhage, (22) Child's bilirubin encephalopathy (neonatal bilirubin concentration is too high, it is easy to be complicated with bilirubin encephalopathy, namely "nuclear jaundice" [also called "severe jaundice"]. There are many complicated reasons, such as ABO blood group or Rh blood group between mother and fetus. Causes hemolysis) (23) Children's rhinitis (including sinusitis) [can be treated with drugs such as Huodan Pill], (24) Children's metabolic disorder, (25) Old age delivery, (26) Umbilical cord (knotted, entangled, too long, too short ...) caused by various reasons (
