What is the reason for the baby's fever and convulsions?

We parents nowadays take good care of our children, because the health of our children is our greatest wish. Sometimes children will have convulsions when they have a severe fever. We think that many times it is because we do not take good care of our children that they get sick. However, sometimes we fail to take care of them. There are reasons for children's illness. Every disease has a reason. So what is the reason for the baby's fever and convulsions? Let’s learn more about it!

Because infants and young children's nervous systems are not fully developed, such as poor inhibitory function of the cerebral cortex and incomplete formation of nerve myelin sheaths, once they are stimulated by external stimuli, excitement can easily spread and cause convulsions. Generally speaking, infants and young children between 6 months and 4 years old, especially those who often catch colds and fevers, are more likely to suffer from febrile convulsions.

Convulsions usually occur when the baby has a high fever, such as a body temperature of 39℃-40℃, and last for a relatively short time, about 2-3 minutes, and generally do not exceed 10 minutes. After the convulsion stopped, the child woke up.

Clinically, children's fever convulsions (febrile seizures) are divided into simple febrile seizures and complex febrile seizures. Among them, simple febrile convulsions are more common in children with good physique between 6 months and 3 years old after birth. The convulsions are systemic, lasting from several seconds to several minutes, generally not more than 10 minutes, and only occur once a day. The child wakes up quickly after the convulsion and becomes drowsy after regaining consciousness, but there is no abnormality in the nervous system. The EEG results within two weeks of the convulsion are normal.

Complex febrile seizures are more common in children under six months old or over four years old. They occur multiple times a day, lasting more than 15 minutes, and there have been more than four febrile seizures. A small number of people have non-systemic seizures, but partial seizures (such as unilateral limb convulsions). After the attack, there are neurological abnormalities such as temporary paralysis.

Now we know the reasons why babies have fever and convulsions. Many people think that parents will be in a good mood only when their children are healthy. Many people also think that if a child is sick, just go to the hospital directly and there is no need to investigate the reasons. However, we should still understand the reasons why the baby is sick so that we can avoid these problems in life.
