Unexplained Seizures in Adults: Could It Be Genetic?
Seizures that don't respond to medication or fit a clear diagnosis? A genetic cause could change your treatment entirely.
How Much Epilepsy Is Genetic?
Genetic factors play a role in the majority of epilepsy. Single-gene causes account for an estimated 30-40% of severe epilepsy and 10-20% overall. A meaningful percentage of adults with epilepsy carry a genetic variant that, if identified, could change their diagnosis and treatment.
When the Genetic Diagnosis Changes Treatment
SCN1A (Dravet syndrome): common sodium channel blockers can actually worsen seizures. GLUT1 deficiency: ketogenic diet is highly effective; standard meds often inadequate. KCNQ2/KCNQ3: specific medications targeting the affected channel. TSC1/TSC2: mTOR inhibitors can reduce seizure frequency. Pyridoxine-dependent epilepsy: responds to vitamin B6. In each case, knowing the gene directly determines the correct treatment.
When to Suspect Genetic Epilepsy
Seizures started in childhood or adolescence. Drug-resistant epilepsy (failed 2+ medications). Associated developmental or cognitive symptoms. Family history of seizures. Unusual EEG patterns. Normal imaging and metabolic workup.
