Diseases Treatment

Anosmia is the technical term for a loss of the sense of smell and taste that persists even when there is no obvious cause such as a head cold. Most commonly, a chronic condition like allergic rhinitis or nasal polyps causes anosmia. It may be a symptom of a tumor of the brain , but this is very rare. It may also occur because of a head injury. This is because such an injury sometimes damages the olfactory nerves. These are the nerves that carry smell sensations, as electrical impulses, from the nose to the brain.

What should be done?

If you notice that you have lost your sense of smell or taste, consult your physician. You will probably find that you have a nasal condition that your doctor can treat, and thus cure the anosmia. If there is no sign of abnormality in your nose, your physician may refer you to a neurologist for some diagnostic tests. It is unlikely that your olfactory nerves have been damaged.
