If a baby has a delayed myelination, most of them can be cured through early comprehensive rehabilitation intervention. Delayed myelination can manifest in various clinical forms, such as delayed motor development, delayed language or cognitive backwardness, etc. It is necessary to bring the baby to the pediatric rehabilitation department for professional evaluation in a timely manner and to provide appropriate early intervention based on the evaluation results. If abnormalities are found, they must be done early because brain myelination develops most rapidly within one year of age, with full development occurring after 6-7 years of age. And it is most critical within one year of age, so early, regular and comprehensive rehabilitation treatment should be given in a timely manner.
