Once a child suffers from mental retardation, it not only affects the future of the child, but also causes a heavy blow to the parents. Studies have shown that a conservative estimate of the number of people with mental retardation in China is over 12 million. Mental retardation is a group of disorders that occur during the developmental period when general intellectual functioning is significantly lower than that of the same age and is also accompanied by adaptive behavior deficits. The main manifestations of mental retardation are as follows: 1. Difficulty in breastfeeding. The earliest symptom of infants with mental retardation in infancy is that they have difficulty feeding themselves, they do not suck, and they are particularly prone to vomiting, which means that there is neurological damage and their intelligence will be affected later. 2. Backward language development. Normal infants will imitate sounds at 7-8 months, call mom and dad at about one year old, say about ten words at one and a half years old, understand simple instructions at about 2 years old, ask simple questions at about 3 years old, and basically express their thoughts at about 4-5 months or even 1-2 years behind in these performances, should be regarded as a signal of intellectual backwardness. 3, motor development is delayed. Low-intelligence baby than normal baby obvious motor development delayed, prone head, sitting, standing, walking and other movements of the starting age than normal children of the same age to late, especially walking more obvious. Often not until 3-4 years old or 4-5 years old will walk on their own, and walking unstable. 4. Abnormal facial and physical appearance. Some babies with congenital mental retardation have abnormal facial and physical appearance, for example, children with congenital stupidity have wide eye spacing, slanted eyes, collapsed nose, tongue often dragged outside the mouth, drooling, etc., which is often referred to as “international face”, children with hydrocephalus have a particularly large head circumference, children with microcephaly have a particularly small head, and children with thyroid The child with hydrocephalus has an unusually large head circumference, the child with microcephaly has an unusually small head, the child with hypothyroidism has an unusually short stature, the child with phenylketonuria has abnormal skin, and the child with white hair is particularly light. The treatment of mental retardation in children should not be delayed! As long as timely detection, scientific and formal treatment, children with mental retardation is not terrible. One of the most important treatment methods is the “Jin San Zhen” therapy in acupuncture. The “Jin’s Three Needles” therapy was founded by Professor Jin Rui, a famous acupuncture expert and academic leader of the Guangzhou University of Traditional Chinese Medicine, and a doctoral supervisor of the School of Acupuncture and Tuina. In the 1980s, Professor Jin was appointed by the Guangdong Children’s Welfare Association as a medical consultant for mentally handicapped children, and conducted research focusing on the treatment of mentally handicapped children, a world problem. Since its inception, the “Jin’s Three Needles” therapy has cured many difficult diseases, especially in the prevention and treatment of retarded children, cerebral palsy and other difficult brain diseases. At present, there are more than eighty “Jin San Zhen” treatment centers for mentally retarded children in China, spreading all over the country. In order to inherit and promote the “Jin San Zhen” therapy, the American Institute of Traditional Chinese Medicine established the “Jin San Zhen Research Center” and the “Jin’s Research Center for Mentally Retarded Children” in California, and set up a corresponding research group. A research group has been established for this purpose. The Chinese American Association for Families with the Disabled calls them the “saviors of the mentally handicapped”.
