The study was conducted with more than 2,500 patients from France, Belgium, and Italy.
It concluded that the majority eventually regained their senses back within two months.
Here’s what the experts think
Experts have a theory that the virus disrupts the pathway for neurons to get to their destination in the brain.
Each olfactory neuron has one odor receptor. Microscopic molecules released by substances around us, like flowers or coffee, stimulate these receptors.
Once the neurons detect the molecules, they send messages to your brain, which identifies the smell and taste.
These support cells are covered in a receptor called ACE-2 which is Covid-19’s primary target in human cells and dulls those senses.
When these pathways get disrupted or crossed, people lose their sense of smell and taste.
Although researchers are not quite sure why the adverse “chemical” taste they actually think that those nerve endings are trying to grow and repair themselves and are hopeful that at least some reaction is occurring.
