Retrospective study of sensitivity and specificity of EEG in the elderly compared with younger age groups

► Some authorities state the EEG is of limited value in the elderly. ► Sensitivity and specificity of EEG was similar in a cohort aged 65 and over compared to two younger cohorts. ► EEG in elderly revealed unsuspected cases of non convulsive status. ► EEG in the elderly is useful in studying confusion and reduced GCS rather than paroxysmal disorders.
