Elaine, have you had multi day EEGs, either ambulatory or in hospital? Luckily our child's negative myoclonics* and atypical absences are controlled with lamotrigine. Nothing completely controlled partials but those have tapered off for the most part. Having the generalized seizures show up after partials had our epileptologist surmise it was probably genetic but generally only ~30% of those with epilepsy are given a cause. And seeing how a fair number of those are going to be genetic or from injury or known infections, don't have high expectations there.

if you ask for a dna test, your doc may be confused. Sue is referring to getting your enzymes checked (not epilepsy genetic testing) which affects only some AEDs but is not a factor for all possible epilepsy drugs.

* these were generalized, not all are generalized from what I've read
