Abstract

Objective

We aimed to explore the role of hyperventilation (HV) during routine EEG recordings in the diagnosis of adults with epilepsy.

Methods

During the COVID-19 pandemic we removed HV from routine EEG recordings due to the transmission risks. Routine EEGs conducted in the year before and after the COVID-19 pandemic were re-evaluated.

Results

A total of 167 HV + and 199 HV - EEGs were analyzed. To ensure comparability between the two groups with respect to age and conditions that could contraindicate HV, patients ≥ 55 years and with any conditions contraindicating HV were excluded from both groups. In patients with a diagnosis of epilepsy the prevalence of epileptiform abnormalities was 26.7 % in the HV + and 24.5 % in the HV - group (p = 0.727).

Conclusions

This study did not reveal any evidence indicating that HV improves the diagnostic sensitivity of routine EEG in adults with epilepsy. In adults, hyperventilation during routine EEG recordings may be most useful in incre in patients with a history of absence seizures or seizures triggered by hyperventilation.

期刊介绍： Neurophysiologie Clinique / Clinical Neurophysiology (NCCN) is the official organ of the French Society of Clinical Neurophysiology (SNCLF). This journal is published 6 times a year, and is aimed at an international readership, with articles written in English. These can take the form of original research papers, comprehensive review articles, viewpoints, short communications, technical notes, editorials or letters to the Editor. The theme is the neurophysiological investigation of central or peripheral nervous system or muscle in healthy humans or patients. The journal focuses on key areas of clinical neurophysiology: electro- or magneto-encephalography, evoked potentials of all modalities, electroneuromyography, sleep, pain, posture, balance, motor control, autonomic nervous system, cognition, invasive and non-invasive neuromodulation, signal processing, bio-engineering, functional imaging.
