To determine whether a child’s developmental delay can be rehabilitated, we need to analyze the degree of the child’s developmental delay, as follows: 1.Can be rehabilitated: If the developmental delay is very mild and there is no organic lesion in the brain, most of them can be rehabilitated and reach the developmental level of children of the same age after regular rehabilitation training; 2.Can’t be rehabilitated: If the developmental delay is very serious, especially if there is organic brain lesion, it is difficult to be rehabilitated. If the developmental delay is very serious, especially if there are organic brain lesions, such as brain dysplasia, brain gyrus widening and brain tumor, it is difficult to recover from these causes of developmental delay. As we can see above, whether a child with developmental delay can be rehabilitated depends on the specific situation.
