Researchers seem to have found why a form of epilepsy does not respond to drug treatment.
Researchers seem to have found why a form of epilepsy does not respond to drug treatment.
Dr Mark Cunningham and his team at Newcastle University conducted a test on patients' brain tissue as part of the study.They found seizures were caused by electrical connections between nerve cells rather than chemical ones, which explains the reason why drugs are ineffective.
The research proceeded with experts coaxing brain tissue removed from people with epilepsy, to behave as if it was still part of the living brain.
Electrical signals from individual neurons and networks of neurons in the samples were then recorded.he tissue was compared to with normal brain tissue activity.
The researchers noted an underlying 'noise,' a particular type of brain wave, which occurs in the intact epileptic human brain.
They found that the oscillation or "noise," a precursor to an epileptic seizure, was not controlled by the usual chemical signals which most conventional anti-epileptic drugs fight.nstead, the scientists observed that the oscillation was linked to electrical connections.

He added: "Currently, there is no treatment to cure epilepsy other than surgery, which at the moment is only effective for small numbers.

Also, a spokeswoman for Epilepsy Research UK said the research was "very promising".
The study appears in Proceedings of the National Academy of Sciences.
