A new treatment for drug-resistant epilepsy with the potential to suppress seizures 'on demand' with a pill, similar to how you might take painkillers when you feel a headache coming on, has been developed by UCL researchers funded by the Wellcome Trust. The treatment, described in Nature , combines genetic and chemical approaches to suppress seizures without disrupting normal brain function. The technique was demonstrated in rodents but in future we could see people controlling seizures on-demand with a simple pill. Epilepsy affects around 50 million people worldwide including 600,000 in the UK and around a quarter of cases are resistant to conventional treatments. Many of these cases could be addressed by the new treatment method, which relies on genetic modification of brain cells to make them sensitive to a normally inactive compound. "First, we inject a modified virus into the area of the brain where seizures arise," explains Professor Dimitri Kullmann of the UCL Institute of Neurology, senior author of the research. "This virus instructs the brain cells to make a protein that is activated by CNO (clozapine-N-oxide), a compound that can be taken as a pill.
