ObjectiveTo identify the clinical significance of epileptic eye movement for localization of posterior epileptic seizures. MethodsThere were 12 posterior epileptic patients, who were undertaken the detailed presurgical evaluation and ictal SEEG recording, and the epileptogenic zone of whom was confirmed restricted within posterior cortex through the boarder of epileptic cortical resection and the result of epileptic surgery, included in the research. ResultsThe cluster analysis of posterior cortical area of interest showed that parieto-occipital sulcus (POS) with the adjacent cortical areas belonged to the Medial Group; intraparietal sulcus (IPS) with the adjacent areas belonged to the Intermediate Group; and the Lateral Group included anterior occipital sulcus (AOS) and posterior temporal cortex. Eyes forced stare had the significant correlation with IPS, POS and related cortical group. Contraversive eye deviation had no significant correlation with cortical eye field with the related cortical areas. ConclusionsForced eye stare was significant eye movement in posterior epilepsy, and had significant correlation with IPS and POS. Ipsiversive eye deviation and convergence binocular movement were rare semiology in posterior epilepsy, and AOS had significant correlation with the two type of epileptic eyes movement.
ObjectiveTo study the clinical characteristics of patients onset epilepsy Dentatorubral-pallidoluysian atropy (DRPLA) in Epilepsy Center of Guangdong 999 Brain Hospital and improve understanding of the disease. MethodsCollected five patients from August 2014 to August 2016 in Guangdong 999 Brain Hospital, whom diagnosed through genetic testing of DRPLA, analysed their disease course, family history, video-EEG, brain MRI and treatment data. ResultsDRPLA performed as neurodegenerative diseases, and epilepsy population mainly performed as progressive myoclonic epilepsy (Progressive myoclonus epilepsy, PME). ConclusionDRPLA is autosomal dominant neurodegenerative disease. In patients with cerebellar atrophy, neurological regression, ataxia, drug refractory epilepsy, it is recommended routinely to detect ATN1 gene, so that timely diagnosis and genetic counseling.
