Summary

Artifacts in electroencephalograms (EEGs) can mimic seizures, leading to incorrect diagnoses. Prompt artifact correction is crucial for accurate patient monitoring and avoiding unnecessary medical interventions.

Area of Science:

Clinical Neurophysiology
Neurology

Background:

Continuous 24-hour EEG and video monitoring is essential for diagnosing frequent seizures.
Intensive care admission with intubation and ventilation may be required for seizure management.

Observation:

A patient presented with frequent seizures requiring intensive care.
Electroencephalogram (EEG) recordings displayed artifactual changes mistaken for electrographic seizures.
Correction of artifacts revealed normal background brain activity.

Findings:

Artifactual EEG changes can be misidentified as true electrographic seizures.
Prompt identification and correction of EEG artifacts are critical.

Implications:

Awareness of EEG artifacts is vital for EEG technologists.
Accurate artifact management prevents misdiagnosis and unnecessary patient interventions.
Improved EEG interpretation enhances patient safety and care outcomes.
