What the literature leaves open

  • Vascular contributions to cognitive impairment and dementia (VCID) are thought to arise from distributed neurovascular unit (NVU) dysfunction rather than focal pathology, yet the transcriptional architecture of human VCID brain tissue and the status of endogenous counter-regulatory signaling within it remain incompletely characterized.
