Hi Welcome to healthcaremagic.com
Witnessing the seizures by a family member is utmost important to make the diagnosis. CT brain and EEG may be normal.
Doctor do treat seizures with Eption when they are having seizures (in hospital).
However, treating first episode of seizures is controversial. Some agree and some do not agree to treat. Risk of seizures is >50% in 2 yrs.
If there are no underlying causes, you can watch.
I also like to know the age of chil/baby who got seizures. If underer 21, phenytoin is not a good choice.
