Olfactory Nerve Disorders

Olfactory nerve disorders affect our sense of smell. This can impact our ability to enjoy food, detect danger like gas leaks, or even notice warning signs like spoiled food.

17. Olfactory Event-Related Potentials (OERPs): Measures brain responses to odor stimuli.
18. Gustatory Tests: To check taste sensation, which can sometimes be affected alongside smell.
19. Neuropsychological Testing: Assessing cognitive function and psychological well-being.
20. Resonance Rhinometry: Measures nasal cavity dimensions and airflow.

Non-Pharmacological Treatments for Olfactory Nerve Disorders:

1. Nasal Irrigation: Using saline solutions to clear nasal passages.
2. Avoiding Irritants: Such as smoke, strong perfumes, or chemical fumes.
