A.R.O.S. (Anosmia Recovery Opal System): Proposed Mechanisms of Action in Long-Term Olfactory Dysfunction

Long-term anosmia is traditionally considered refractory due to degeneration of peripheral receptors and central olfactory maps. Here we propose A.R.O.S. (Anosmia Recovery Opal System) as a multimodal mineral–neuromodulatory framework capable of re-engaging olfactory function even after prolonged sensory deprivation. The system integrates intranasal mineral stimulation, auricular neuromodulation, trigeminal activation, and bioactive phytochemical signaling to influence peripheral regeneration and central neuroplasticity simultaneously.

We hypothesize that structured mineral–silica interfaces, combined with targeted trigeminal and autonomic modulation, create permissive conditions for reactivation of horizontal basal cells, enhancement of local microcirculation, and restoration of sensory afferent input. This renewed peripheral signaling may drive reorganization within the olfactory bulb, orbitofrontal cortex, and limbic networks through activity-dependent plasticity mechanisms, including BDNF-mediated synaptic remodeling.

A.R.O.S. represents a conceptual shift from single-target olfactory training toward systems-level sensory reactivation, offering a novel, testable model for anosmia rehabilitation and interdisciplinary research at the interface of neurobiology, bio-mineral science, and neuromodulation.

The schematic illustrates the multimodal interaction between intranasal mineral stimulation, trigeminal sensory activation, auricular neuromodulation, and central olfactory–limbic pathways. The model highlights potential roles of basal cell activation, trigeminal–olfactory coupling, and neuroplastic reorganization following long-term olfactory deprivation. This figure represents a conceptual framework and does not depict a validated clinical pathway.
