[Jacksonian seizures in the clinical picture of supratentorial brain tumors].

An analysis of the structure and frequency of Jackson's seizures during the illness in 27 patients with brain tumors displayed correlation of these parameters with a histological type of a neoformation and a degree of the involved mediobasal brain structures. In the process of development of the disease the epileptic activity in the EEG was replaced by a slow activity. The displayed peculiarities of the structure and the course of Jackson's seizures taking into account other clinical manifestations can be used in preoperational diagnosis of a histological nature of a tumor.
