Objective To investigate the electrophysiological character,seizure symptomatology and seizure transmission mode of cingulate gyrus epilepsy. Methods 10 patients with cingulate gyrus epilepsy confirmed by stereoelectroencephalography(SEEG)and had good postoperative outcomes in Department of Neurosurgery,the Second Hospital of Lanzhou University from March 2015 to June 2022 were analyzed retrospectively,and their electrophysiological character,seizure symptoms and corresponding propagation patterns were analyzed separately. Results Scalp electroencephalography in 4 cases of anterior cingulate gyrus epilepsy and 2 of middle cingulate gyrus epilepsy could provide valuable information for lateral localization of epileptic foci. The scalp electroencephalogram of 4 cases of posterior cingulate gyrus epilepsy was difficult to provide meaningful lateral localization value and was often misleading. Therefore,10 patients underwent SEEG evaluation,which could clearly identify the epileptic focus. Anterior cingulate gyrus epilepsy was mainly characterized by complex motor symptoms with fear. Middle cingulate gyrus epilepsy manifested as goal-directed motor behavior and rigidity posture. Epilepsy in the posterior cingulate gyrus was a pseudo temporal lobe symptom. The anterior cingulate gyrus mainly involved emotional networks. The middle cingulate gyrus mainly involved the pre-motor area and auxiliary motor area in the motor network. The posterior cingulate gyrus mainly spread to the temporal lobe and inferior parietal lobules,causing temporal lobe symptoms. Conclusions Although cingulate epilepsy has variable clinical symptoms and is difficult to locate and diagnose,there is still a certain pattern to follow. Familiarity with functional connectivity of different subdivisions of the cingulate gyrus is a prerequisite for the correct diagnosis and location of epilepsy in this region. In the diagnosis of cingulate epilepsy,SEEG plays an important role in its location. [ABSTRACT FROM AUTHOR]
