What is most important to document in the history of your EEG patient?

Documenting the last seizure is crucial in the history of an EEG patient because it provides specific, pertinent information about the patient's condition and can significantly impact the interpretation of the EEG results. The timing of the last seizure can help clinicians assess the frequency, type, and potential triggers of seizures, which are critical in diagnosing epilepsy or other seizure disorders. Additionally, understanding when the last seizure occurred allows for a more accurate baseline comparison during the EEG study.

While cardiac history, psychiatric history, and head circumference can also be relevant in specific contexts, they do not carry the same immediate relevance as the timing of the last seizure in relation to EEG interpretation and potential seizure activity during the recording. Knowing the last seizure enables the technologist and neurologist to better correlate the electroencephalographic findings with the patient’s clinical history and symptoms.
