## TL;DR

This paper discusses the importance of interpreting EEG patterns in epilepsy diagnosis and management, covering normal and abnormal brain activity.

## Contribution

The paper provides an educational curriculum from the ILAE to improve EEG interpretation in epilepsy care.

## Key findings

- EEG interpretation is crucial for diagnosing and managing epilepsy.
- The ILAE curriculum addresses normal and abnormal EEG patterns and includes advances in EEG analysis.
- Understanding ictal and interictal patterns is essential for accurate epilepsy diagnosis.

## Abstract

The accurate interpretation of scalp EEG remains an instrumental diagnostic component of epilepsy care. Knowledge of what constitutes normal EEG findings, non‐epileptiform abnormalities, and epileptiform patterns—both ictal and interictal—is essential for appropriate patient management. The International League Against Epilepsy (ILAE) has developed an educational curriculum containing learning objectives necessary to accurately diagnose and manage people with epilepsy. In this Seminar in Epileptology, we address the learning objectives related to assessment and interpretation of EEG background activity, normal sleep patterns, provocation methods, interictal abnormalities, and ictal patterns, as well as a brief discussion on relevant advances in scalp EEG analysis and future perspectives on this topic.
