Short review highlights the benefits of olfactory and visual training for neurodegenerative conditions, suggesting innovative rehabilitation strategies.
Post-COVID-19, olfactory and visual training have demonstrated health benefits, particularly for individuals with visual impairments and neurodegenerative conditions such as Parkinson’s and glaucoma. Integrating olfactory training with essential oils and developing multisensory technologies could improve the quality of life for those with sensory deficits, underscoring the brain’s adaptability and the therapeutic potential of herbal ingredients. This short review commentary proposes that the neuroplastic interplay between the olfactory and visual pathways, including their demonstrated anatomical and functional convergence, may provide a conceptual foundation for integrating olfactory stimulation into future visual rehabilitation strategies.
