Introduction:
Despite recent advances in neuroimaging and genetics, electroencephalography (EEG) continues to play a central role in the diagnosis and management of epilepsy. One application of EEG is called pharmaco-EEG. This technique is highly sensitive in detecting the effects of drugs on brain functioning and shows potential in predicting the efficacy and tolerability of anti-seizure medications (ASMs).
Areas Covered:
In this narrative review, the authors discuss the most salient data concerning the effects of different ASMs on EEG. The authors aim to provide a clear and concise overview of the current state of research in this area, while also identifying opportunities for future investigation.
Expert Opinion:
To date, pharmaco-EEG does not appear to be clinically reliable for predicting treatment response in epilepsy, as the literature is limited by underreporting of negative results, a lack of controls in many studies and insufficient direct replication of previous findings. Future research should focus on controlled interventional studies, which are currently lacking.

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...
