Genetic testing is used to diagnose types of epilepsy that are known or suspected to be caused by genetic mutations or variations. It is also used for people who may have an unknown cause of epilepsy.
Genetic tests mostly use DNA taken from a blood sample, but in some cases a saliva (spit) sample, cheek swab, or skin biopsy can be used. There is no one-size-fits-all genetic test, so multiple tests may be recommended. A genetic counselor can help you navigate questions about the types of tests, what they may tell you, and your options. Test results will help your doctor make an accurate diagnosis, develop the right treatment plan (such as effective antiseizure medication), and decide whether more evaluations should be considered.
