Abstract
Olfaction impairment is one of the earliest nonmotor symptoms of Parkinson’s disease. Olfaction disorders in patients with Parkinson’s disease can range from hyposmia, a reduction in smell ability, to anosmia, a complete loss of smell. Regardless of severity, olfaction loss can result in decreased well-being and mood disorders. However, there is no approved management for anosmia or hyposmia secondary to Parkinson’s disease. Insulin is hypothesized to modulate olfactory neuron regeneration in patients with post-infectious hyposmia, but its effects have not been studied in Parkinson’s patients. Using a randomized controlled trial design, we seek to determine whether eight weeks of daily application of intranasal insulin results in a significant improvement in olfaction performance over baseline in Parkinson’s patients with a 6-month minimum history of anosmia or hyposmia. The results from this study could provide an evidence-based treatment option for this bothersome non-motor symptom, for which there are no treatment options.
