Iodine deficiency in child is one of the factors that diminish his/her mental and intellectual development. The impact of the severity of iodine deficiency on both intellect and memory has been studied. It has been established that reproduction of verbal information diminishes and visual memory and other mental activity deteriorate in iodine deficiency. The number of accentuated personalities increases in the groups of children with decreased iodine levels. Self-overestimation occurs more frequently in these groups than that in a group of children with normal levels of this trace element. The manifestation of egocentrism and aggression increases in proportion with the more severity of iodine deficiency.
