Researchers at the University of California Institute of Neurology have discovered a network of connections in the frontal lobe of the brain involved in frontal epilepsy attacks. The results of the study were published in the journal. magazine brain.
The team analyzed MRI scans of 47 patients who had undergone frontal lobe surgery. The scientists found that participants were less likely to have seizures when the neural pathways in the brain that connect the frontal lobe to the thalamus and striatum (responsible for transmitting sensory and motor signals) were cut. Seizures stopped completely in 88% of patients after three years and in 80% after five years. Typically, seizures stop completely in only 30% of cases.
At the same time, the rupture of the ligaments did not have any adverse effects on speech or executive functions.
“Neurosurgery can be a very effective solution for people with epilepsy. However, some patients have relapses years after surgery and it is not clear why. We now think that this may be due to the connections in the brain that make up the network that causes epileptic seizures. If this is true, this network in the frontal lobe Closing it down can prevent attacks from repeating years later,” he said.
