Does Epilepsy in Children Have a Genetic Link?

Question

The first child developed epilepsy at the age of two. If they have a second child, is there a risk of this condition being inherited across generations?

Answer

For the vast majority of children with epilepsy, it is most often acquired later in life, but a small percentage of patients may have a genetic link related to inherited conditions. Particularly, some children with this genetic defect may have a significant link to inherited epilepsy. However, for most children with epilepsy, it is caused by acquired factors, such as certain infections, especially those affecting the central nervous system. For instance, some children with hand, foot, and mouth disease may develop brain infections again if the virus infection is severe and if their immunity is very weak.
