Mild mental retardation

Introduction Mental retardation is classified into four categories: mild, moderate, severe, and extremely severe in the international classification. The manifestations of mild mental retardation are: IQ is 50 to 70, which is not much different from normal children in preschool age and is not easy to be found. After entering school, the performance is difficult, the grades are not good, and some knowledge can be obtained after receiving special education. When you are an adult, you can eat your own food, and some can build a family. Lack of flexibility, predictability, and need help in special circumstances, otherwise it is nervous and uncomfortable to adapt to society. Responding to less serious mental factors, prone to reactive psychosis, schizophrenia. No obvious language barriers. This disease generally does not have physical deformities and nervous system dysfunction. 80% of mental retardation is this type.

Cause

The etiology of mental retardation is complex and involves a wide range of factors, such as biological factors, psychosocial factors and other factors, which may lead to brain function development blockage or brain tissue damage. With the development of modern medical science, some cases can be found, but many cases have not yet found the cause of the disease.

Diagnostic criteria for mild mental retardation: 1 IQ 50 to 70; 2 no obvious speech disorder; 3 low learning ability can not successfully complete primary education, can learn certain life skills.

Differential diagnosis

Differential diagnosis of mild mental retardation:

(1) Temporary delay in mental development: children with chronic physical illness, post-illness state, malnutrition, taking calming drugs or poor environment, lack of learning conditions, etc., can cause children to be sluggish, lack of thinking, and easily mistaken for intelligence Low and mental retardation. If you improve your living conditions and learning conditions or physical recovery, your intelligence can recover quickly.

(2) Epilepsy: Frequent seizures and taking phenobarbital, carbamazepine, and valproic anti-epileptic drugs can all cause drowsiness, sluggishness, and similar mental retardation.

(3) Children with schizophrenia: There may also be low academic performance, apathy, contact with the surrounding environment and maladaptation, but most children do not have real mental retardation.

(4) Visual and auditory obstacles, so as to adapt to the environment and learning difficulties: In the early years, people with severe deafness often have language development disorders, and do not mistake these situations for mental retardation. Aphasia, misuse, and loss of writing caused by certain encephalopathy also affect learning and language skills, but their general intelligence is good.

(5) Children with ADHD: lack of concentration, poor academic performance, lack of discipline, and poor social ability, similar to mental retardation, but the intelligence is often within the normal range, and the academic performance can be significantly improved. The medication can be improved, and these manifestations can be differentiated from mental retardation.

(6) Some normal children also have a slow development of speech ability and exercise ability, but their ability to understand and adapt to the environment is still normal. Once the function is developed, they can quickly catch up with normal children, and they are not significantly backward in all aspects, and mental development. The delay is different.
