[Vestibular disorders in contusions of the temporal lobe of the brain].

An analysis of the caloric test results in 30 victims of a severe contusion-crush of the temporal lobe of the brain showed that to this type of pathology the common significant changes in the vestibular-oculomotor reflex which, more often than not, found their expression in the prevalence of an experimental nystagmus in the direction toward the affected hemisphere. The victims, in whom contusions of the temporal lobe were attended by lesions of the brain stem of the primary or dislocation genesis, demonstrated the presence of vestibular areflexia or dissociaton of the quick nystagmus phase. Against the background of a continual tonic component there would become evident gross functional disruptions of the oculomotor elements which in a number of cases proved unrecognizable with an ordinary clinical observation.
