[Course of epilepsy and its population constants].

A study of the population constants in 499 patients with unfavorable forms of epilepsy demonstrated a relative autonomy in the development of the epileptic process. This process is demonstrated by the frequency of seizures rather than by the age periods. Some important parameters of the population characteristics of the epileptic disease involve the character of the development of the convulsive process, correlation of convulsive and nonconvulsive forms, and correlation between the frequency of seizures and duration of the epileptic process.
