Electroclinical seizure
An EEG pattern with a definite time-linked clinical correlate, or both EEG and clinical improvement after parenteral antiseizure medication.
Criteria & assessment
- An EEG pattern with a definite time-locked clinical correlate, OR EEG AND clinical improvement after parenteral antiseizure medication.
- A definite correlate must accompany the pattern and be absent when that pattern is absent; subtle signs can qualify.
- Duration <10 s qualifies only with a definite clinical correlate. An ECSz need not meet ESz; report both when both qualify.
