The people epylepsy-suffering were divided into native people and non-native people in the researched population. Among epileptics the percentage of tyvans was 75,47%, from which the percentage of men was 56,09% and the percentage of women was 43,91%. General spread of epilepsy among native people was 2,54 ± 0,28 in the researched population which corresponds to the level of spread of epilepsy in the population without taking in the account ethnic characteristic. The measures of average debut of epilepsy, average age on the moment of research, average duration of epilepsy among tyvans, didn’t differ from measures of non-native people. The ethiological spectre of epilepsy among natives and non-natives corresponded to the one in the rest og regions of Russia and world.
