Myelin hypoplasia can lead to delayed development of neural information transmission and analysis in the brain, which can manifest as poor motor, language, cognition or physical coordination, and requires timely examination and evaluation in the child health department or rehabilitation department. When abnormalities exist, appropriate rehabilitation training should be given in a timely manner. Rehabilitation training includes gross motor, language, fine motor, intelligence, as well as hydrotherapy, waxing and physical therapy. Drugs such as rat nerve growth factor, brain protein hydrolysate, and pediatric intelligence syrup can also be applied when necessary. However, drugs are generally less effective in myelin dysplasia, and rehabilitative training is preferred, and the precursor must be evaluated.
