How is infantile spasms treated?

Patient's question:

Patient gender: Male
Main symptoms: Occasional nodding
Onset time: Before and after sleep
Laboratory test results: Infantile spasms

Doctor's answer:

Hello, your son's symptoms may be myoclonus. There are many factors or causes that can lead to myoclonus. Epilepsy (including infantile spasms), cerebellar ataxia, hypocalcemia, and some metabolic diseases may all cause myoclonus. In infancy, due to the underdeveloped nervous system, transient myoclonus may occur. Normal children may also experience myoclonus during sleep, which is not pathological. Myoclonus caused by epilepsy and infantile spasms, among other conditions, is usually accompanied by epileptic discharges on an electroencephalogram (EEG). The EEG of infantile spasms shows characteristic discharges. If myoclonus frequently recurs and a standard EEG is normal, a 24-hour ambulatory EEG monitoring can be performed to improve the detection rate of epileptic discharges. Video EEG can also be conducted to rule out pseudo-seizures. It is worth mentioning that EEG is a non-invasive test, and parents need not have concerns.
If your child's myoclonus recurs and can be treated with a single dose of vitamin B6, it may be due to vitamin B6 deficiency or vitamin B6 dependency. Children with myoclonus should first have their underlying cause identified, especially whether it is epilepsy. Therefore, if your child experiences myoclonus, it is important to consult a pediatric neurologist. If epilepsy is diagnosed, standard anti-epileptic treatment should be followed as prescribed. If vitamin B6 deficiency or dependency is confirmed, supplementing with vitamin B6 is sufficient, as long-term use has no significant side effects. In some cases, dietary imbalances in children or breastfeeding women may lead to insufficient vitamin B6 intake. Adjusting the diet can correct this issue.
I hope this helps.
