Be alert to the symptoms of mild developmental delay!

For mild developmental delay, the symptoms are not obvious in infancy, but learning difficulties may gradually appear during school age. Although language development is slightly behind, general social language is sufficient. Treatment of mild developmental delay must be discovered and started as early as possible.

1. Mild: IQ is 50-69 (accounting for 80%-85%). In the preschool period, except for the delayed development of speaking and walking, other abnormalities are not easy to find. In infancy, language and motor function development may be delayed, and there are no obvious abnormal signs of physical and nervous system development. During school age, learning difficulties may gradually appear. Although language development is slightly delayed, social language is still acceptable, and the child can still take care of himself and engage in simple labor and technical operations. Difficulty calculating, reading, writing, applying abstract thinking, lack of flexibility and dependence on others.

2. In terms of personality traits, there are mainly stable type (stable type) and unstable type (excitable type). Stable people are generally quiet and obedient, can master certain labor skills, work and study honestly, and are easy to get sympathy and care from others. The unstable type often talks incessantly, keeps moving around, lacks self-awareness, and is easily disliked or teased. The more severe cases of mild mental retardation are equivalent to what we usually call "stupidity", and the cause of this type of patient is often difficult to find. If you find that your child has the above symptoms, you should see a doctor immediately and receive timely treatment.

3. Infancy is the period of fastest brain, psychological and physical development. From newborns to 7 years old, brain weight is close to that of adults. The differentiation of cerebral cortical cells begins in the fifth month of fetal development and is basically completed by the age of 7 (with exceptions for some individuals with certain physical conditions). After birth, the number of nerve cells in the cerebral cortex no longer increases, and the increase in brain weight is mainly related to the increase in the volume of nerve cells, the increase in the number and length of synapses, and the myelination of nerve fibers.

4. According to relevant data: within three months after birth, there is a 100% cure rate; within three years, there is only a 65% cure rate; at six to seven years old, the cure rate is less than 12%, or it cannot be cured at all, so mild mental retardation must be discovered and treated early to avoid regrets; however, prenatal examinations are now popular, which is a blessing!
