What are the symptoms of brain development delay?

Symptoms of delayed brain development can also manifest in many aspects, such as slow response to the outside world, especially when the child is six months old and still cannot focus on slowly moving objects in front of them, and often drools and has delayed language development, which are all symptoms.

1. Slow response to the outside world

Some babies are slow to respond to external stimuli. At 6 months old, they still cannot look at slowly moving objects above their faces, cannot turn their heads in the direction of sounds, cannot turn over by themselves, and cannot sit steadily without the help of adults such as their parents. This is also a manifestation of mental retardation in babies.

2. Drooling from July to September

Babies have the habit of drooling, so mothers will put a bib on their babies. This is because when the baby is 4-5 months old, the addition of complementary foods plays a vital role in the baby's growth. The baby's diet gradually begins to be supplemented with foods containing nutrients such as starch. After the salivary glands are stimulated by these foods, saliva secretion increases significantly.

At this time, the baby's mouth is small and shallow, and the swallowing reflex function is not yet perfect. He cannot use swallowing movements to regulate saliva, so as long as there is too much saliva, it will flow out of the mouth. In addition, many babies like to suck their fingers, pacifiers, etc., which also stimulates the secretion of salivary glands and increases saliva.

However, if the baby still drools frequently at 7-9 months old and grinds his teeth when awake, parents should pay attention. This may be caused by sequelae of encephalitis, cretinism, or facial nerve paralysis, which lead to dysfunction in regulating saliva. Although the chances of this happening are very low, you should go to the hospital for diagnosis and treatment.

3. Language development is delayed

Some smart babies will babble and imitate adults' speech at 9 months old, but some babies' language development is relatively backward. By 10 months old, they can't babble and their pronunciation is not clear. At this time, mom and dad should learn some tips on how to teach their baby to speak and train their baby to learn to speak.

4. Lack of interest in surroundings

Some babies lack interest in the people and environment around them, do not like to interact with others, and lack emotional attachment. In this case, parents should not take it lightly, but should care for the baby more, talk to the baby more, and make the baby more cheerful. At the same time, they should also consult some experts to confirm whether the baby has any problems and let the baby receive timely treatment.
