Q

delirium generally manifests as ____________________ on electroencephalography (EEG). An exception is delirium tremens, which is associated with ___________. EEG lacks sensitivity and specificity for the diagnosis of delirium but it is useful for ruling out ____________________.

A

delirium generally manifests as diffuse background slowing on electroencephalography (EEG). An exception is delirium tremens, which is associated with fast activity. EEG lacks sensitivity and specificity for the diagnosis of delirium but it is useful for ruling out non-convulsive seizures
