Non-invasive scalp stimulation shows promise for drug-resistant epilepsy
A doctoral researcher studied transcranial direct current stimulation as a home-based therapy for epilepsy patients who don't respond to medication. The method uses electrodes on the scalp to deliver weak electrical currents, avoiding surgery. The research was conducted with neurologists at Ghent University Hospital.
The research was conducted within the PerStim project, pairing Beumer with neurologists at Ghent University Hospital. Observing surgeries firsthand gave him direct exposure to patients living with epilepsy. His thesis examined how personalized transcranial electric neurostimulation could offer an alternative for those who don't respond adequately to medication.
A key finding emerged from experiments with healthy participants: stimulation's effects appear to involve scalp nerve activation alongside direct brain influence, suggesting the mechanism is more complex than previously assumed. Beumer stressed that engineers and clinicians must improve communication to translate findings into practical treatments, and he hopes future work will develop more refined stimulation approaches.
This research could eventually offer epilepsy patients a home-based treatment alternative to invasive surgery, which carries risks and uncertain outcomes. If the method proves effective in further trials, it may reduce hospital visits and give patients greater autonomy in managing their condition. However, the findings also indicate the underlying mechanisms remain incompletely understood, meaning widespread clinical adoption could still be years away. Patients with drug-resistant epilepsy, who currently face limited options, may be the primary beneficiaries if these personalized stimulation techniques mature into reliable therapies.
