The causes of 1382 readmissions of 156 patients with traumatic epilepsy were studied with regard to the seasonal and pathogenic factors. It was established that readmissions of patients with traumatic epilepsy directly correlated with the spring and autumn seasons and 8 pathogenic factors (no maintenance therapy, psychogenias, dysphorias, intoxication with antiepileptic drugs, alcoholization, infectious diseases and inadequate rehabilitative measures). The data obtained will help neuropathologists and psychiatrists to time repeated prophylaxis of traumatic epilepsy under outpatient conditions.
