Dynamic limbic-executive decoupling underpins the reciprocal link between drug-resistant epilepsy and depression in temporal lobe epilepsy

This neuroimaging study of 82 temporal lobe epilepsy patients and 50 controls examined whether disrupted functional connectivity between limbic and executive brain networks explains the bidirectional relationship between drug-resistant seizures and depression. Using resting-state fMRI combined with receptor mapping and gene expression analysis, the researchers identified specific patterns of brain network integration that statistically link drug resistance severity and depression symptoms.
