Abstract
Objectives- To investigate the association between APOE genotypeand cognitive and emotional outcome following spontaneoussubarachnoid haemorrhage (SAH). Materials and methods-Neuropsychological assessments were conducted with 70 SAHsurvivors derived from a consecutive series of neurosurgicaladmissions. Outcomes, including cognitive tests, health questionnairesand Glasgow Outcome Scale at a mean of 16 months after SAH, werecompared with presence or absence of the e4 allele. Results- There wasno evidence that SAH survivors possessing the e4 allele had pooreroutcome. The only suggestion of an association between the e4 alleleand outcome was in a subgroup of patients with a Fisher grade 4haemorrhage, although this trend did not reach statisticalsignificance. Conclusions- Overall, possession of the APOE e4 allele isnot significantly associated with neuropsychological outcomefollowing SAH. However, there may be an effect amongst those with aFisher grade 4 haemorrhage.
