Patient's question:
How is mental retardation treatedDoctor's answer:
Analysis of the Condition: The causes of mental retardation can be broadly categorized into the following groups.(1) Genetic factors:
① Chromosomal abnormalities, such as Turner syndrome, pseudoathetoid dementia, and cri-du-chat syndrome;
② Genetic metabolic disorders, such as phenylketonuria, galactosemia, and familial black tapetum dementia;
③ Tuberous sclerosis, such as neurofibromatosis;
④ Craniofacial malformations, such as primary microcephaly and hydrocephalus.
(2) Prenatal factors:
① Infections, such as various viral infections in early pregnancy (e.g., rubella, cytomegalovirus), which can cause harm to the fetus and affect its normal development;
② Toxins, such as the effects of smoking and alcohol, certain drug side effects, and poisoning from carbon monoxide, pesticides, etc.;
③ Physical injuries, such as trauma, hypoxia, and radiation;
④ Endocrine diseases, such as hypothyroidism;
⑤ Maternal diseases, such as malnutrition, pregnancy-induced hypertension, and preeclampsia.
(3) Perinatal factors: Premature birth, asphyxia, kernicterus, intracranial hemorrhage, and birth injuries.
(4) Postnatal factors: Infections, head trauma, toxins, epilepsy, malnutrition, and endocrine diseases.
(5) Psychosocial factors: Primarily refers to situations where children are deprived of educational opportunities due to various reasons during their early years. Some studies suggest that adverse psychosocial factors can lead to mental retardation, such as children raised in unusual environments, like feral children.
Guidance on Treatment: The treatment methods for mental retardation include:
(1) Etiological treatment: In some cases of mental retardation, the cause is clear, and effective treatment can be targeted. For example:
① Phenylketonuria: A low-phenylalanine diet can be adopted, including rice, cornstarch, vegetables, fruits, and lamb, while limiting the intake of foods rich in phenylalanine (e.g., wheat, protein, fish, shrimp, dairy products). Low-phenylalanine hydrolyzed protein can also be used, with a typical daily dosage of 3–10 grams.
② Galactosemia: Dairy products should be avoided, and early consumption of rice flour, wheat flour, or formula foods is recommended, supplemented with multiple vitamins and inorganic salts.
③ For endemic cretinism, early thyroid hormone treatment and iodine supplementation should be administered.
④ For congenital hypogonadism, testosterone propionate 25 mg can be administered intramuscularly twice a week.
⑤ For children with congenital hydrocephalus, ventriculoperitoneal shunting may be performed.
⑥ For mental retardation caused by congenital syphilis, penicillin should be used for treatment.
(2) Symptomatic treatment: Since the cause of many cases of mental retardation is unknown, even if the cause is identified, there are currently no specific treatments. Therefore, symptomatic treatment may sometimes be necessary. Antipsychotic medications such as chlorpromazine, perphenazine, and haloperidol can be given to children with excitement, agitation, hallucinations, or delusions. Antianxiety medications like diazepam and lorazepam can be used for those with anxiety and restlessness. Anticonvulsant medications such as phenytoin, diazepam, and nitrazepam can be administered for seizures. Additionally, drugs such as glutamic acid, vitamins, and phosphatidylcholine can be used to promote brain metabolism and improve intelligence.
(3) Surgical treatment: Surgical intervention may be performed to improve the function of certain organs in cases of disabilities or malformations, such as ankyloglossia, cleft lip, or cleft palate.
(4) Education and training: Education and training for children with mental retardation should be started as early as possible and maintained consistently, with individualized approaches. Specific educational and training goals and plans should be developed based on the degree of retardation and the nature of the deficits. Parents should be patient, helping children to gradually adapt to their surroundings and engage in simple labor. For mildly mentally retarded children, education should be prioritized, along with the development of good habits and the acquisition of basic labor skills to enable independent living. For severely mentally retarded children, care should be the focus, preventing accidents, disabilities, and infections.
Guidelines for Family Life with Mentally Retarded Children:
Key Principles for the Diet of Mentally Retarded Children:
Focusing on the diet of mentally retarded children is a crucial aspect of family life guidance. Increasing foods rich in B1, B6, and C vitamins, as well as trace elements, glutamic acid, and γ-tyrosine, can promote brain cell metabolism and enhance intelligence, benefiting all mentally retarded children. Except in cases where protein or lecithin intake is contraindicated due to specific diseases, a diet rich in protein and lecithin can be encouraged to support brain development. Additionally, for children with congenital nutritional deficiencies, it is important to consciously supplement the deficient nutrients. For example, children with hypothyroidism should be given thyroid hormone, while those with phenylketonuria should limit phenylalanine intake to 15–30 mg per kilogram of body weight per day. Children with galactosemia should completely avoid dairy products and rely on rice flour, wheat flour, or soy milk as their primary food sources. Children with Wilson's disease should limit high-copper foods such as pork, lamb, liver, and shellfish, opting instead for low-copper, high-protein diets.
Ensuring the Safety of Mentally Retarded Children:
Protecting the safety of mentally retarded children is a vital part of family life guidance. Mentally retarded children often lack the ability to distinguish between safety and danger, yet most retain some level of self-movement. Their safety must not be overlooked. For children with excitement or agitation, the living environment should be kept simple, with metal objects, fragile items, sharp-edged items, and small, ingestible objects removed. Their activity range should also be limited to prevent falls, collisions, burns, and other accidents. For children with depression or isolation, they should not be left alone, as these children may develop negative or pessimistic attitudes, leading to potential accidents.
Caring for the Daily Life of Mentally Retarded Children:
Caring for the daily life of mentally retarded children is also a key component of family life guidance. Parents should provide comprehensive care and attention, including diet, clothing, and hygiene, while preventing infections. It is also important to avoid ridicule, discrimination, provocation, or stimulation, as these can lead to impulsive, destructive, or self-injurious behaviors.
Emphasizing the Intellectual Development of Mentally Retarded Children:
Parents must not believe that intellectual development for mentally retarded children is futile. Early training and education in language, motor skills, observation, calculation, imagination, and thinking can significantly improve their abilities. Parents should encourage the development of one or two labor skills, preferably non-intellectual and physical tasks, such as sewing, cutting, or woodworking. This will help them transition smoothly into employment and adapt to social life, achieving self-sufficiency and independence.
