It remains unclear whether cognitive impairments in haematological cancers are associated with biological vulnerabilities reflected in these parameters. We examined whether cognitive and psychological morbidity correlated with blood cell parameters before, during, and after chemotherapy in individuals with aggressive lymphoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Neuropsychological testing and self-reported questionnaires were administered at diagnosis, mid-chemotherapy, and 6\u20138\u00a0weeks post-treatment (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200930). Regression models assessed associations between cognition and blood cell parameters. Bootstrapped Pearson correlations examined relationships between NLRs, SIIs, PLRs, and psychological symptoms. To test specificity, similar analyses were conducted in healthy controls (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200972).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In individuals with aggressive lymphoma, NLRs, SIIs, and PLRs correlated with impairments in inhibitory control, cognitive flexibility, delayed recall, and working memory across time points (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). A disconnect emerged between these parameters and subjective self-reports.
