About EEG-Features in Cases with Brain Tumors in the Area of the 3-rd Ventricle and a Clinical Picture Characterized by Pronounced Somnolence. Об изменениях ЭЭГ при опухолях в области 3-го желудочка, сопровождающихся гиперсомническим синдромом.

: In the majority of patients with brain tumors in the area of the third ventricle and a clinical picture characterized by pronounced somnolence, the background EEG showed, along with typical delta-waves, the spindle-shaped theta-activity in the form of bilaterally synchronized bursts. It was most prominent on the parietal leads. This activity increased sharply during sleep and in the state of sopor. This data may be of interest in relation to the problem of sleep pathophysiology. It is suggested that the presence of such activity in combination with delta-waves may be a bad prognostic sign for the patients with tumors in the area of the third ventricle. : In the majority of patients with brain tumors in the area of the third ventricle and a clinical picture characterized by pronounced somnolence, the background EEG showed, along with typical delta-waves, the spindle-shaped theta-activity in the form of bilaterally synchronized bursts.
