Must I consider surgery for my temporal lobe epilepsy at 27?

Question

Hello doctor,

I am 27 and have drug-resistant temporal lobe epilepsy that is destroying my life despite being on maximum tolerated doses of multiple medications. My EEG shows continuous epileptiform activity in the left mesial temporal region, and my MRI revealed hippocampal sclerosis consistent with mesial temporal sclerosis.

I am currently on Levetiracetam 2500mg twice daily, Lamotrigine 400mg twice daily, and Topiramate 200mg twice daily, but I am still having four to six complex partial seizures monthly. My recent drug levels were therapeutic: Levetiracetam 35 μg/mL, Lamotrigine 14 μg/mL, and Topiramate 12 μg/mL.

The seizures involve auras of rising epigastric sensation followed by staring, oral automatisms, and confusion lasting two to four minutes with 30 to 45 minutes of postictal confusion. Last week, I had a secondary generalized tonic-clonic seizure at work and was hospitalized overnight. I lost my job as a graphic designer because I cannot function reliably. The medications are causing severe cognitive side effects; my memory is terrible, I have word-finding difficulties, and I feel mentally dull all the time. My neurologist referred me for epilepsy surgery evaluation since I have a clear seizure focus.

Should I pursue temporal lobectomy?
Are there any less invasive options, such as laser ablation?
What are the realistic risks of memory loss from surgery?
I am scared of brain surgery, but these seizures are preventing me from having any kind of normal life or career.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

So your situation is incredibly challenging, and your concerns are completely valid. Drug-resistant temporal lobe epilepsy (seizures originating in the brain's temporal lobe persist despite trials of two or more appropriately chosen and tolerated anti-seizure medications), especially with confirmed mesial temporal sclerosis (a common, chronic condition characterized by scarring (gliosis) and neuronal loss in the hippocampus and surrounding deep (mesial) structures of the temporal lobe) on MRI (magnetic resonance imaging) and localized epileptiform activity on EEG (electroencephalogram), is one of the most well-studied and surgically treatable forms of epilepsy.

Given your ongoing seizures despite high therapeutic levels of multiple antiepileptic medications, you are a strong candidate for surgical intervention. Temporal lobectomy (a neurosurgical procedure that removes a portion of the brain's temporal lobe, commonly performed to treat drug-resistant epilepsy), particularly anterior medial temporal lobectomy, has shown high success rates in reducing or even eliminating seizures in patients like you. However, surgery does come with risks, especially when it involves the dominant hemisphere, where language and memory functions may be localized. Memory impairment, especially verbal memory, is a potential risk, particularly if the seizure focus is on the left side. That said, many patients report improved overall cognitive functioning after surgery because the seizure burden and medication side effects often lessen postoperatively. Less invasive options such as laser interstitial thermal therapy (LITT) or stereotactic radiosurgery offer alternatives with shorter recovery times and may carry a lower risk of cognitive side effects, though seizure control rates may be slightly lower than open surgery.

A comprehensive presurgical evaluation, including neuropsychological testing, high-resolution imaging, and possibly intracranial EEG (intracranial electroencephalography) monitoring, will help define the safest and most effective approach for you. Given how profoundly your seizures are affecting your independence, career, and quality of life, pursuing surgical evaluation is a reasonable and potentially life-changing next step

I hope this answers your query.

Please let me know if I can assist you further.

Thank you.
