Proposal for electroencephalogram standardization in aircrew selection.

Current diagnostic electroencephalogram (EEG) investigations in aircrew selection and certification lack both standardization and reference to universally applicable criteria for their effective use. Extrapolation from clinical EEG studies may not be appropriate. Recent studies on serial EEGs in aircrew are lacking, whereas follow-up of individuals who failed certification is nonexistent. Population-based EEG studies in healthy subjects are generally underpowered to establish the significance of pathological EEG findings. Advanced digital video/EEG recording, in combination with standardization of data exchange formats and automated detection of pathological grapho-elements, is cost effective when carried out for extended periods, e.g., during flight simulator sessions. Extensive databases of serial video/EEG records in aircrew may thus be easily obtained and validated over time. Prognostic inferences on the significance of pathological EEG discharges may subsequently be derived from these databases.
