Octreotide's effects on delayed story recall in memory-impaired patients. Delayed recall scores are presented as percentage of saline performance: >100% represents octreotide-induced memory enhancement, and <100% represents octreotide-induced memory decline. APOE genotype and DRS score modulated octreotide's effects on delayed recall. For ε4- patients, individuals with the highest DRS scores also had the greatest octreotide-induced memory facilitation (Spearman r=0.7167, p=0.0298). In contrast, ε4+ patients showed a trend for higher DRS scores to be associated with lower octreotide-induced memory facilitation (Spearman r=-0.7537, p=0.0835).
