The intelligence quotient (IQ) is 2.0 standard deviations below the average of the population (the average IQ of the population is set to 100, and the IQ of one standard deviation is 15). Generally, the IQ below 70 (or 75) means that the intelligence is significantly lower than the average level. Adaptive behavior includes two aspects: personal living ability and fulfilling social responsibilities. Developmental period generally refers to under 18 years of age. There are various names for mental retardation. "Psychiatry

Diagnose based on

First, the presence or absence of MR should be determined according to IQ, adaptive behavior, and age of onset, and then the cause of MR should be further searched. During the diagnosis process, children's growth and development history should be collected in detail, physical and neuropsychological examinations should be comprehensively performed, and the growth and development indicators of children of different ages at different developmental stages should be compared and compared with normal children of the same age to determine their intelligence level and adaptability. Make a clinical judgment. At the same time, with appropriate intelligence tests, a diagnosis can be made and the severity of MR can be determined.

1. Medical history collection (1) Family history: It should be known whether the parents are married to close relatives, whether there are blind, dumb,

Treatment principles

1. Etiology has been identified, such as chronic disease, poisoning, long-term

1. Primary prevention includes the following: health education and nutrition guidance; prenatal and perinatal health care (high-risk pregnancy management, neonatal intensive care, discouraging pregnant women from drinking and smoking, avoiding or discontinuing drugs that adversely affect fetal development) ); immunization of infectious diseases (virus, bacteria, protozoa); genetic metabolic examination and counseling (avoid marriage between close relatives, find carriers); environmental protection (prevent physical and chemical pollution, poisoning and noise damage); reduce the brain Traumas and accidents, correct treatment of brain diseases, control of seizures; strengthen preschool education and early training; prohibit neglect and abuse of children. The purpose of these measures is to prevent the occurrence of MR.

2. Secondary prevention measures include: Follow-up of high-risk neonates, early detection of disease, and treatment. In particular, attention should be paid to the supply of early nutrition (protein and trace elements such as iron, zinc, etc.) and appropriate environmental stimulation for good intellectual development. Role; regular health checks on preschool children (physical, nutritional, mental and psychological development, vision and hearing); screening for metabolic diseases of newborns (such as hypothyroidism, phenylketonuria); prenatal diagnosis, amniotic fluid Examinations (chromosomal diseases, neural tube defects, metabolic diseases). Secondary prevention mainly consists of early diagnosis and special treatment.

3. Tertiary prevention requires comprehensive prevention from society, school, and family. Early detection of MR, early intervention and stimulation; effective help to the family, keeping the family structure intact, and improving the function of children with MR. The fundamental approach to prevention is to continuously deepen the research on the etiology of MR. Only by taking measures against the cause can prevention be more effective.
