Abstract:
We report sudden unexpected death in epilepsy (SUDEP) following resective epilepsy surgery in two patients who had been documented as seizure free. One patient had been weaned off of anticonvulsants and was leading a normal life. The other patient had discontinued only one anticonvulsant but had recently started working night shifts. Following resective epilepsy surgery, one of the major objectives among patients, caregivers, and the healthcare team is to safely wean patients off anticonvulsant medications. The main concern regarding anticonvulsant withdrawal is seizure recurrence. While SUDEP following surgical resection has been reported, to our knowledge, there have been no confirmed cases in patients who have been seizure free. Considering the patients reported here, and given that there are no concrete guidelines for the safe withdrawal of anticonvulsants following epilepsy surgery, the discontinuation of anticonvulsants should be considered carefully and must be accompanied by close monitoring and counseling of patients regarding activities that lower seizure threshold, even after successful epilepsy surgery.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
