Impaired sense of taste or smell
There are many nerves involved in transmitting taste and smell information to the brain. Taste receptors are found within taste buds, not only on the tongue, but also on the soft palate, pharynx, larynx, epiglottis, uvula, and the top third of the oesophagus.
Complete loss of taste is very rare, even in multiple sclerosis, but impaired taste or distorted taste may occur with demyelisation of any of the nerves involved. In particular, the Trigeminal Nerve or 5th Cranial Nerve plays an important part in the taste and smell process.
I have experienced the distorted taste sensation, where everything you eat or drink has an unexpected taste. In fact, most everything tasted pretty disgusting. This persisted for about a month and during this time eating was most definitely not a pleasure.

I am not aware of any specific treatments to help overcome impaired taste or smell.
