Posterior Parolfactory Sulcus Dysfunction

Posterior parolfactory sulcus dysfunction might sound like a mouthful, but it’s essentially a condition where the groove at the back of your brain, responsible for processing smells, isn’t working as it should. In simpler terms, it affects your sense of smell. Let’s delve into what this means, what causes it, and how it can be managed.

Posterior parolfactory sulcus dysfunction refers to impairment in the functioning of the groove in the posterior part of the olfactory sulcus, leading to a diminished or altered sense of smell.

Treatments:

Non-Pharmacological:

1. Olfactory Training: Exercises to stimulate and improve the sense of smell.
