title: [Syndrome of aspontaneity in frontal lobe tumors].
abstract: The syndrome of aspontaneousity in tumors of the frontal lobes is expressed in a sharp decrease of initiative, spontaneous volitions, crude changes in the emotional sphere and peculiar disorders of thinking. In a "clear" form, i. e. without changed consciousness, the syndrome proceeds with signs of increased distractability and a combination of distrubances of wakefulness with rapid fatigueability. The first variant is more characteristic of bilateral intracerebral tumors, located on the level of the callosum sorpus. The second--for large unilateral tumors, exerting influence on the opposite frontal lobe and frequently on the diencephalic area.
