Does mental retardation need EEG

summary

Mental retardation is a kind of mental retardation, which is caused by incomplete brain development or organic damage. Now let's see if mental retardation needs EEG.

Does mental retardation need EEG

First of all: mental retardation requires EEG. Laboratory examination included biochemical examination of blood, urine, brain and spinal fluid, head X-ray and CT examination, cerebral angiography, electroencephalogram, evoked potential, audiometry, chromosome analysis, pituitary, thyroid, gonad and adrenal function test, virus (such as cytomegalovirus, rubella virus), protozoa (such as Toxoplasma) and antibody test, etc. The relevant items should be determined according to the diagnosis.

Secondly, intelligence test is often used in mild Mr, but it is difficult to use intelligence test in severe MR, so we must rely on behavior rating scale, which is less reliable than intelligence test in differentiating mild Mr. Therefore, the two methods should be used together, and the inspection results must be analyzed comprehensively.

Finally: the intelligence of children with mental retardation is significantly lower than that of normal people. The average IQ of normal people is 100. When a child's IQ is 100, it means that his intelligence is normal. If a child's IQ is below 70, his intelligence is said to be significantly lower than the average level (simplified as "IQ below 70"). Only two out of 100 children of the same age have IQ scores below 70.

matters needing attention

If it is found that the motor development is backward, the response to the outside world is slow, the language development is poor, the expression is dull or has a special face, this time should go to the regular hospital for examination as soon as possible, make the correct diagnosis and corresponding treatment.
