Children with mental retardation may have motor, language, adaptive, and social deficits. Children with Mental Retardation are typically behind in two or more areas of development, including gross motor, fine motor, language, adaptive, and social skills. Mental retardation can be characterized by lagging behind in these areas, such as poor fine motor skills in the hands, weak muscle strength, less speech, and poorer interaction with others. If your child has mental retardation, you need to go to the hospital in time for examination and evaluation, and then carry out comprehensive rehabilitation training in time.
