Research goal

To understand biological factors contributing to epilepsy, its comorbidities and its outcomes.

Research overview

Epilepsy is one of the most common neurological illness across the lifespan, and is characterised by an enduring predisposition to generate epileptic seizures. The causes and mechanisms implicated in such ‘enduring predisposition to generate epileptic seizures’ are incompletely understood.

Epilepsy is a serious disorder. In addition to experiencing the unpredictability of seizures, people with epilepsy face increased risks of adverse health outcomes, including social and employment restrictions, psychiatric and neuropsychological comorbidities, antiseizure drug toxicity, injuries, and in some cases the possibility of sudden unexpected death in epilepsy (SUDEP). It is also noteworthy that, despite the introduction of several new antiseizure drugs in the past 25 years, the treatment outcomes in epilepsy have not changed substantially, with approximately two-thirds of patients continuing to have seizures on appropriate antiseizure drug therapy.

Our group applies clinical, electrophysiological and molecular approaches to understand the biological factors contributing of epilepsy, its comorbidities and its outcomes. Defining these factors can ultimately lead to identify improved precision-based epilepsy therapies.

Projects

Project title: The genetics of focal epilepsies
Project description: Focal epilepsies are the most common forms of epilepsy, and have traditionally been regarded as disorders related to an 'acquired' brain insult, such as head injury, stroke or tumour. In reality, most cases of focal epilepsy have no identifiable cause. This project aims to assess the extent to which genetic factors account for focal epilepsies of unknown cause, by applying both clinical and genetic testing approaches. This project will allow the prospective student to acquire knowledge on epilepsy and epilepsy genetics, working within a successful collaborative framework which has been at the forefront of advances in epilepsy genetics and treatment at the international level.

Project title: Cardiorespiratory and autonomic changes in epilepsy
Project description: Cardiorespiratory and autonomic changes can occur in people with epilepsy, and their causes are multifactorial. Cardiorespiratory and autonomic changes following a generalised or bilateral tonic-clonic seizure have received much attention, as they can ultimately result in sudden unexpected death in epilepsy (SUDEP). However, the multifaceted aspects of ictal, peri-ictal and interictal cardiorespiratory and autonomic manifestations are not fully understood. This project aims at addressing this knowledge gap by utilising different approaches in the inpatient and outpatient settings. The findings of this project will enhance our understanding of cardiorespiratory and autonomic function in epilepsy, and may shed light into mechanisms underpinning premature mortality in epilepsy, including SUDEP.
