Neurobehavioral sequelae of the anatomical bleeding pattern
Several authors stress the great prognostic relevance of the presence of intraventricular and/or intracerebral blood for the neurological result after SAH, even if the amount of further subarachnoid blood is small (Gerber et al., 1993; Auer, Schneider and Auer, 1986; Adams, Kassell and Torner, 1985; Gurusinghe and Richardson, 1984; Fisher, Kistler and Davis, 1980). From a neuropsychological point of view, Odgen, Mee and Henning (1993a) reported that SAH patients with intracerebral hemorrhage exhibited a significantly worse memory performance 10 weeks after the acute event which persisted at follow-up 12 months later. However, Tidswell et al. (1995) could not find any correlation between the bleeding pattern on CCT and the cognitive deficits of the patients. It does not become clear from the study of Tidswell et al. (1995) according to which criteria the CCT scans had been evaluated and which aspects of the bleeding pattern were investigated by the authors.
