Abstract


Purpose- To review the usefulness of short term video EEG (VEEG) recording in children experiencing recurrent paroxysmal neurological events.

Method- We retrospectively reviewed a 2-hour VEEG recording data of 44 children 1 month- 16 years age.

 

Results- Events were detected in 18 children. 15 events were epileptic and 3 were non-epileptic.  The 3 nonepileptic events were tonic posturing, dystonic posturing and pseudo seizure.

In 15 children we classified seizures as generalized in 4 - myoclonic atonic in 3, tonic clonic in 1. 6 children had focal onset seizures; 4 were motor (tonic, clonic, tonic- clonic, myoclonic in 1 each) and 2 were non-motor in the form of behavioural arrest. 5 children had epileptic spasms 3 symmetric and 2  asymmetric.

Ictal EEG showed generalized EA in all children with generalized seizures. In 2 children with focal motor seizures, ictal EEG identified the seizure onset, whereas in 2 movement artefacts were recorded. The ictal EEG was normal in both children with behavioural arrest. In children with epileptic spasm, ictal EEG showed focal predominance in 3.

Inter ictal EEG was abnormal in all children except 1 with behavioural arrest.

The above data confirmed the diagnosis and aided management in children with seizures, whereas in those with non-epileptic event, it helped to taper and omit AEDs.

Conclusion- Short term VEEG recording is an economical and valuable diagnostic tool with recurrent paroxysmal events as event was recorded in 41% children.
