If your baby does not have a fever but has convulsions for no apparent reason, it is likely that epilepsy is the cause. There are many causes of epilepsy, and some of them are caused by organic lesions in the brain, so you need to take your child for a cranial MRI to confirm the diagnosis. The other cause may be primary epilepsy, there is no organic lesion in the brain, but the EEG can often be detected, but the phenomenon of convulsions, ordinary EEG may not be enough, it is best to take the baby to do video EEG, but also long-range monitoring video EEG, is more important to find out the cause of the convulsions. If the cause is epilepsy, it may be benign epilepsy or malignant epilepsy. If it is benign epilepsy, the child can often recover on his or her own after puberty. But more severe epilepsy requires that the baby be given medication to treat it, and that the medication not be stopped at random, as stopping it can trigger seizures.
