Why is my epilepsy uncontrolled despite taking medicines?

Question

Hello doctor,

I am 33 and have refractory focal epilepsy that is not responding to multiple antiepileptic medications despite therapeutic levels. My EEG shows frequent epileptiform discharges in the left temporal region, and my MRI revealed mesial temporal sclerosis.

I am currently on Levetiracetam 2000 mg twice daily, Lamotrigine 300 mg twice daily, and Lacosamide 200 mg twice daily, but I am still having three to four complex partial seizures monthly.

My recent drug levels were all therapeutic: Levetiracetam 28 μg/mL, Lamotrigine 12 μg/mL, and Lacosamide 18 μg/mL. The seizures involve staring, lip smacking, and automatisms lasting one to three minutes, followed by 20 to 30 minutes of confusion.

Last month, I had my first generalized tonic-clonic seizure in two years and was taken to the ER by ambulance. My driver’s license was suspended again, and I lost my job because I cannot reliably commute to work.

The medications are causing significant cognitive side effects; my memory is terrible, and I feel mentally foggy all the time.

My neurologist mentioned an epilepsy surgery evaluation since I have a clear focus in the temporal lobe. Should I pursue surgical options like temporal lobectomy? Are there newer medications, such as Cenobamate, that might help? I am scared of brain surgery, but these seizures are destroying my independence and future. What are the realistic risks and benefits of surgical intervention?

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Your case of refractory focal epilepsy with confirmed mesial temporal sclerosis and persistent seizures despite high-dose, therapeutic levels of multiple antiepileptic drugs clearly qualifies you as a strong candidate for epilepsy surgery evaluation.

Temporal lobe epilepsy, particularly with evidence of mesial temporal sclerosis on MRI (magnetic resonance imaging) and a consistent seizure focus on EEG (electroencephalogram), has one of the highest rates of surgical success.

A standard anterior temporal lobectomy or selective amygdalohippocampectomy can offer long-term seizure freedom in up to 60 to 80 percent of carefully selected patients.

Given your continued seizures, cognitive decline, medication side effects, and serious life consequences such as job loss and driving restrictions, surgery could significantly improve your quality of life and reduce the risk of future injuries or status epilepticus.

While surgery carries inherent risks such as language or memory deficits depending on the side of the brain involved, these are thoroughly assessed during presurgical evaluation, including video-EEG monitoring, neuropsychological testing, and possibly functional MRI or intracranial EEG to precisely localize seizure onset and map eloquent cortex.

Newer medications like Cenobamate have shown promise for focal seizures in drug-resistant epilepsy and may be considered, especially if surgery is delayed or not feasible, but they can also carry risks such as drug interactions and cardiac side effects.

Ultimately, the decision between further medical therapy and surgical intervention depends on a detailed evaluation by a comprehensive epilepsy center, but based on your history, surgery may offer your best chance at regaining independence and cognitive stability.

It is completely valid to feel afraid of brain surgery, but living with uncontrolled epilepsy at your age carries its own serious and escalating risks.

I hope this has helped you.
