In families with two or more relatives with subarachnoid hemorrhage (SAH), other first-degree relatives have an increased risk of SAH. We studied the presence of unruptured intracranial aneurysms in 125 members of 23 families with familial SAH, defined as two or more affected first-degree relatives, in a cross-sectional design. ⋯ Because the yield is high, screening is recommended in first-degree members of families with familial SAH. Repeated screening should be considered in relatives who have been treated for familial intracranial aneurysms.

To demonstrate the effects of cerebral lateralization and temporal dynamics on somatosensory perception. ⋯ The findings demonstrate clearly that left/right perceptual thresholds for simple somatosensory stimuli are asymmetric in healthy right-handed subjects. Both central and peripheral asymmetries exist. The central asymmetry and gaze effects are consistent with right cerebral dominance for externally directed attention. Access of somatosensory stimuli to conscious awareness is delayed and particularly vulnerable to disruption at 50 to 100 msec after onset of the stimulus.

To determine the presence of chronic traumatic brain injury in professional soccer players. ⋯ Participation in professional soccer may affect adversely some aspects of cognitive functioning (i.e., memory, planning, and visuoperceptual processing).
