There was significant worsening in cognition over time, measured by MMSE, CDR and mPACC in CU and MCI, with more rapid worsening in MCI for all cognitive tests. At baseline, higher levels of PlGF (β=0.156, p<0.001), lower levels of sFlt-1 (β=-0.086, p=0.003), and higher levels of IL-8 (β=0.07, p=0.030) were associated with more WML in CU. In MCI, higher levels of PlGF (β=0.172, p=0.001), IL-16 (β=0.125, p=0.001), IL-8 (β=0.096, p=0.013), IL-6 (β=0.088, p=0.023), VEGF-A (β=0.068, p=0.028), and VEGF-D (β=0.082, p=0.028) were associated with more WML. PlGF was the only biomarker that was associated with WML independent of Aβ status and cognitive impairment. Longitudinal analyses of cognition showed independent effects of CSF inflammatory markers and WML on longitudinal cognition, especially in people without cognitive impairment at baseline.DiscussionMost neuroinflammatory CSF biomarkers were associated with WML in individuals without dementia. Our findings especially highlight a role for PlGF, which was associated with WML independent of Aβ status and cognitive impairment. %U //www.ebmtp.com/content/neurology/early/2023/03/07/WNL.0000000000207113.full.pdf
