One-and-a-half-year-old children, MRI detection, abnormal signals near the posterior horn of bilateral lateral ventricles, considering the possibility of myelination, please combine clinical dynamic observation. what's the meaning This abnormal signal at this position is the manifestation of myelin sheath disease. Generally speaking, there are three common reasons, the first is poor myelination, the second is demyelination, and the third is "slow" myelination (this word is not used well).

Simply explain to you, myelin sheath is a layer of fatty tissue wrapped around some nerve axons, which has insulation effect, improves the conduction speed of nerve impulses and protects axons.

For example, it is like clothes worn by some neurons.

Demyelination change means that this dress was originally good, but later it "rotted" for other reasons, so the neurons look naked, so there must be problems, and the specific problems should be considered in detail.

The so-called poor myelination means that the "clothes" of this neuron are not "made" for some reason, but the result is the same as before, "still no clothes to wear"

The so-called slow myelination is because the child's myelin sheath is in the process of forming before the age of three. At present, it may be that "this dress" is made slowly and not ready yet, which does not mean that there is something wrong with the dress.

Therefore, your child's condition is mainly that the second situation is entangled with a third party, and it is impossible to judge whether it is poor or slow, so it is necessary to observe whether it meets the performance of poor myelination.
