ObjectiveTo analyze the types and characteristics of common paroxysmal diseases in order to improve the diagnosis of onset types and to analyze the related factors of epileptic seizures in Tibetan population.Methods510 patients with paroxysmal diseases were enrolled in the Department of Neurology, People's Hospital of Tibet Autonomous Region from June 2013 to December 2018 and the video electroencephalogram (VEEG) data were analyzed.ResultsAmong the 510 patients, there were 35 types of paroxysmal diseases, 335 cases (65.69%) of seizures and 86 cases (16.86%) of psychogenic non-epileptic seizures (PNES). There were significant differences in the incidence of seizures between male and female patients (P<0.05), the incidence of seizures were different at different altitude and the concentration of hemoglobin (P<0.05), the course of seizures was always more than 2 years (P<0.05), and the frequency and age of seizures were higher, but there were no significant difference, and epileptic patients in Tibet were more likely to be young adults (34.51%).ConclusionsThere are many kinds of paroxysmal diseases in Tibetan population, and epileptic seizures are the main type. There was a qualitative relationship between the incidence of epilepsy and altitude. The incidence of epilepsy didn’t increase along with the increase of hemoglobin, and the course of seizures was mostly more than 2 years.
