Are these seizures? The EEG is not conclusive but the CFM is suggestive of seizures. Normal CFM and continuous EEG. Trace from infant with non ketotic hyperglycinaemia – note very amplitude CFM and frequent high voltage EEG bursts.

Are these seizures? The EEG is not conclusive but the CFM is suggestive of seizures
Trace from infant with non ketotic hyperglycinaemia – note very amplitude CFM and frequent high voltage EEG bursts
Severe suppression of CFM with low voltage EEG bursts but no clear EEG seizure pattern
Repetitive seizures – CFM hard to classify – often changes to severe suppression after treatment with anticonvulsants
Probable seizure but EEG not characteristic – CFM has normal amplitude
Variation in CFM amplitude possibly due to change in sleep/awake state; EEG moderately discontinuous
Artefact – CFM/EEG cannot be classified – initial part of trace appears normal
Probable movement artefact rather than seizure - CFM otherwise normal
Exaggerated sleep wake cycling pattern – common during recovery phase – note movement artefact with nursing care
Gross artefact - Note abnormal impedance in lower half of slide – CFM trace cannot be interpreted
Gross artefact probably due to detached electrodes Note abnormal high impedance in lower half of slide – CFM trace cannot be interpreted
CFM suspicious of frequent brief seizures but EEG not characteristic – full EEG exam needed
Rapidly recovering CFM trace – EEG initially moderately discontinuous
Initial very suppressed CFM – sudden increase in amplitude probably due to seizures
Severely suppressed CFM with some low voltage bursts on EEG and artefact due to handling of infant
Probable pulse artefact which is abolished by change of position of head
Seizure on severely suppressed background with frequent low voltage bursts
Frequent high voltage sharp waves on EEG causing seizure like elevation of CFM
Normal continuous EEG activity and normal CFM with some sleep/wake pattern
Moderately abnormal trace with burst suppression pattern improving initially
