CLAIM CARD
By contrast, several real-world observational cohorts report null or ambiguous findings on contextual outcomes. The MEMOGAL study's null cognitive findings stand in tension with mechanistic hypotheses linking aggressive LDL-C lowering to neurocognitive harm. These convergent null findings from both observational and RCT-derived analyses suggest that PCSK9 inhibition does not adversely affect cognition, a concern that had been raised in earlier lipid-lowering literature.
