There is always a concern about the false alarms and unneeded electrical jolts in the imminent epileptic seizures. Seizures cannot be treated with medication in about a ~17 million epilepsy patients worldwide. Usually a short pulse of electricity is sent to the brain to stamp out a seizure just as it begins to erupt, the drawback is that brain implants trigger too many false alarms.
A new software by Associate Professor of Biomedical Engineering, Sridevi V. Sarma and her group passed the test on real-time brain activity recordings collected from four patients with drug-resistant epilepsy who had experienced seizures while being monitored.
Here is a video…
This detection technique reports that the system yielded superior results, including flawless detection of actual seizures and up to 80 percent fewer alarms when a seizure was not occurring. The main principle behind this is significantly cutting the number of unneeded pulses of current that would be sent to the brain.
In early testing using brain wave recordings rather than live patients, the upgraded system significantly cuts the number of unneeded pulses of current that would be sent to the brain, an important improvement. If you introduce electric current to the brain too often, we don’t know what the health impacts might be. Also, too many false alarms can shorten the life of the battery that powers the device, which must be replaced surgically.- Sridevi Sarma, assistant professor of biomedical engineering at The Johns Hopkins University.
