Research Themes
Research Summary

The development and assessment of novel therapies for the treatment of neonatal seizures.
Co-ordinating and leading a consortium of 14 European Research Teams with over 50 basic scientists and clinicians (including neonatologists, neurophysiologists, paediatric neurologists, pharmacologists and statisticians) and successfully completing the project and clinical trial of "Treatment of Neonatal Seizures with medication off-patent" (NEMO) funded by the EU-FP7 framework.  NEMO has been Europe's first multicentred, controlled trial of antiepileptic drugs for newborn babies (http://nemo-europe.com/).  Unlike in adults, no new antiepileptic drugs have been developed for newborn babies, mainly because of ethical and logistical challenges, including the need for continuous electro-encephalography (EEG) monitoring for drug development.  We assessed whether bumetanide would be an effective novel antieptic drug.  However due to an increased occurrence of hearing loss the trial had to be stopped early.  The results of this study were published and highlighted in Lancet Neurology (Pressler et al, Lancet Neurology 2015), which reflects that NEMO has taken a "major step towards improving the treatment of seizures in neonates" (Glass H, Lancet Neurology 2015).

Epileptiform discharges and cognitive function in children with epilepsy:

Epileptiform EEG discharges are common in children with epilepsy.  However they are not confined to people with epilepsy and the frequency of such discharges is only weakly associated with indices of severity.  Indeed their clinical relevance in highly controversial and a principle of treatment is to avoid over-interpretation of epileptiform activity.  Experimental data shows that interictal spikes and ictal discharges are generated by different populations of neuron through different cellular and network mechanisms and may represent a condition that delays or prevents seizure onset.  Cognitive testing during EEG monitoring has shown disturbances of cognitive function during subclinical discharges.  The latter phenomenon of Transistory Cognitive Impairment (TCI) has been confirmed in some 50 studies, but the impact on daily life is still unclear.  My PhD aimed to study the effect of epileptiform discharges on psychosocial functioning in children with epilepsy.  I performed a randomised controlled clinical trial treating subclinical discharges in children with epilepsy and was able to show for the first time that suppression of discharges was associated with an improvement of behaviour (Pressler et al 2005.  I continued this work with EEG-correlated fMRI (Centeno et al, under peer-review, Choudhary et al HBM 2013) and PET (McGinnity et al 2015) studies, and in our current study on the effect of epileptiform discharges in sleep on memory consolidation in children with focal epilepsy.

Teaching Summary
