FLT1 and Mental deterioration: Higher expression of FLT1 in endothelial cells and microglia was associated with worse cognitive performance at last visit before death (endothelial–FLT1 [logFC = −0.089, FDR = 0.009] and microglia–FLT1 [logFC = −0.176, FDR = 0.009]) and faster cognitive decline (endothelial–FLT1 [logFC = −0.771, FDR = 0.041] and microglia–FLT1 [logFC = −1.964, p = 0.009]).
