“…Moreover, the effects of anaesthetic agents on the ERG are only partially understood and also it is difficult to obtain the necessary normative data with these protocols. For these reasons corneal-contact electrodes are not uniformly used in paediatric studies [8,9,10,11,12,13]. In addition, the use of non-disposable corneal electrodes may now be precluded in some countries because of the risk of contamination.…”

Early diagnosis of herpes simplex encephalitis in childhood

et al. 1982

In the initial phase of HSE the clinical symptomatology is more variable and insidious in babies and young children than in older children and adults. Combined clinical, neurophysiological and neuroradiological studies have been carried out in 12 children with proven HSE. Ten patients had the first EEGs taken during the acute phase of the illness and all showed large amplitude irregular slow activity, sharp waves and often spikes with variable distribution; in 7 cases periodic phenomena were recognisable. At a later stage localised low amplitude EEG activities were found in children with focal neurological symptoms. Areas of low attenuation were seen in the CT scans of the 7 children who had this investigation done at an early stage of their illness. Such low density regions persisted at follow-up and eventually cerebral atrophy with irregular features became obvious. Prompt EEG investigations combined with CT scans provide an early diagnostic clue for treatment. Follow-up EEG studies (including VEP) and CT scans may help assess the severity of residual cerebral damage in the survivors.

Neurophysiological studies in GM1, gangliosidosis

Neurophysiological studies (EEG, ERG, VEP) have been carried out on 8 children with proven GM1 gangliosidosis (3 of Type I and 5 of Type II). All the EEGs were abnormal showing an increasing amount of irregular slow activity as the disease progressed. Around 2 to 3 years of age, Type II patients often showed a fluctuating 4-5 c/s rhythmic activity especially prominent in the temporal regions. Paroxysmal activity was not a conspicuous feature in any of the patients. The ERG was normal in all cases but the VEP was variably altered. The EEG/ERG/VEP findings in GM1 gangliosidosis differ from those seen in most other neurometabolic disorders of childhood.
