Your competent? doctor is already aware of the nose to brain axis and diligently working on solutions for survivor recovery, right? OH NO! Knows nothing AND does nothing! You really picked the worst of the lot. And your board of directors is so incompetent they can't recognize incompetence in their hospital!

Abstract: The nose-brain axis (NBA) is a crucial bidirectional deliverypathway between the nasal cavity and the central nervous system (CNS) that influences both neurophysiology and disease progression. In addition to serving as a route for drug delivery, the NBA plays an active role in neurological disorders by mediating inflammatory responses, microbial interactions, and environmental exposure. Emerging evidence suggests that the NBA may be mechanistically relevant to CNS disorders, particularly within neurodegeneration frameworks such as the Braak and dual-hit hypotheses, which emphasize early olfactory or other peripheral involvements. This review explores how micro/nanoparticles interact with the NBA, not only as therapeutic carriers but also as factors contributing to neuroinflammation and neurodegeneration. Pathogenic micro/nanoparticles, including environmental pollutants and industrial nanoparticles, have been implicated in the exacerbation of CNS disorders by triggering oxidative stress and immune activation in both nasal and brain tissues. Conversely, therapeutic micro/nanoparticles such as biomimetic, synthetic, and cell-derived formulations represent promising strategies for modulating neuroinflammation, enhancing neuroprotection, and restoring CNS function through nasal-targeted interventions. However, substantial gaps remain in the existing understanding of the influences of nasal immune responses, microbiota, and barrier integrity on CNS health through the NBA. Addressing these challenges is critical for leveraging micro-/nanoparticles for the prevention and treatment of CNS diseases.
