Epilepsy is a persistent, noncommunicable brain condition that impacts people of any ages and is one of the most prevalent neurological conditions worldwide, impacting roughly 50 million individuals. Nearly 80 percent of epileptics reside in low- and middle-income countries. If properly detected and dealt with, it is approximated that up to 70 percent of people with epilepsy could live seizure-free lives. Epileptics face a risk of early death up to three times that of the general population.
Now, new findings come from a cooperation between the Institut de Neurosciences des Systèmes (France), the IRCCS E.Medea– La Nostra Famiglia (Italy) and the Department of General Psychology of Padua University (Italy) make detection a less agonizing procedure.
The group made giant strides towards a different method of finding seizures. When no seizure is taking place, New research found that modifications in large-scale neuronal activations can be detected in the brains of epileptic patients throughout periods. The study, released in the journal Epilepsia, compared the high-density EEGs of 37 clients with temporal lobe epilepsy to those of 37 healthy controls.
Results also revealed a correlation in between modifications in the neuronal avalanches spread and memory loss, a typical symptom of epilepsy. Memory processing takes place mostly in the temporal lobe, and epilepsy might change normal patterns of neural propagation throughout rest.

” Even while a seizure is not taking place, the brain of a patient with epilepsy provides some alterations in its network dynamics at the whole-brain scale. We thought it would be possible to take a look at the characteristics by looking at aperiodical, spontaneous neuronal avalanches”.
Even at rest, the brain is constantly producing waves of neuronal activation. The studys authors showed that irregularities in the proliferation patterns of massive neuronal avalanches can be spotted even in the “resting state,” a finding that could one day be used as a diagnostic tool for epilepsy. These neuronal avalanches start with the spontaneous activation of a cluster of neurons and waterfall throughout large regions of the brain.
For patients with epilepsy, its not a lot of fun identifying the specific areas of the brain causing seizures. Currently, the only method to find where a seizure originates from is to catch it while its occurring. To induce a seizure, epileptics are frequently kept in the medical facility for a number of hours or even days being weaned off of their medications with electrodes connected to their heads in the hopes that they will finally have a seizure. As quickly as that happens, the electroencephalographic (EEG) scans can identify the exact place of the seizures origin in the brain. Its an useful diagnostic tool for identifying a patients kind of seizure, which assists medical professionals determine the best treatment options.

” We discovered that the alteration of the dispersing of neuronal avalanches in temporal lobe epilepsy is clustered around those brain areas which are essential for seizure initiation and diffusion” state Duma and Sorrentino. “This opens up the possibility to a brand-new preliminary diagnostic technique, especially crucial for the difficult cases where scalp EEG stops working to find seizures and extra investigations are required.”.
New research found that changes in massive neuronal activations can be spotted in the brains of epileptic patients during durations when no seizure is taking place.
” Our new technique is capable of identifying appropriate features of epilepsy by just considering the basal practical organization of the brain” said Gian Marco Duma and Pierpaolo Sorrentino, respectively researchers at IRCCS E.Medea and the Institut de Neurosciences des Systèmes in Marseille, who collaborated on this research study.
