CLAIM CARD
Within this outcome class, a significant tension exists between the null primary cognitive findings in the MCI trial (Hajjar 2020) and the positive cerebrovascular reactivity finding from the CEDAR study (Henley 2023). This disagreement highlights a disconnect between a potential mechanistic effect on cerebral perfusion and a lack of demonstrable benefit on standardized cognitive batteries. Furthermore, the severity of the disagreement is amplified when considering that the positive CEDAR finding contrasts with numerous null effects on other vascular aging markers across the corpus, suggesting that any cerebrovascular benefit may be narrow and not broadly anti-aging.
