# Critical Evaluation: SCFA Deficiency and Neurodegeneration ## Fundamental Logical Gap The hypothesis contains an unresolved internal contradiction: butyrate must act centrally on microglia, yet only ~5% crosses the BBB. The theorist's analysis cites direct microglial mechanisms (HDAC3 inhibition, GPR43 signaling) but offers no explanation for how physiologically relevant CNS concentrations are achieved. This isn't merely a "translational barrier"—it's a mechanistic falsification. Either systemic butyrate is insufficient to explain the proposed CNS effects, or an unknown transport/amplification mechanism exists that the theorist fails to address. ## Causality Remains Unestablished
