New PCS symptom - lost sense of smell.
 

I take it that losing sense of smell is a PCS symptom? Has anyone else had this. I just noticed it now, because the farmers are spraying the fields next to me and I can't smell it, and this is something you normally wouldn't miss!

It could also be direct trauma to the cranial nerve. As I recall, the olfactory nerve is routed through a "strainer" kind of structure, and a sharp impact, especially to the rear of the skull, can cause some or all of the nerves to actually shear.

This is the classic drunk falling backwards off his barstool and losing his sense of smell. Not saying this happened to you, but wanted to rule it out.

No, I hit my forehead. I do have some smell, but its greaty reduced, also have had a lot of sinus pain.

My sense of smell was quite reduced. I think it goes along with damage to the brain stem area (balance, vision, sound, etc.).

Lost sense of smell
 

Yes my sense of smell is almost gone and sometimes I smell things nobody else does like something is burning etc.
I agree with all the above posts. This is definately a symptom of PCS. My dad also has lost his sense of smell and he has Parkinson's disease. Apparently this is a fairly common symptom with neurological conditions.
It has affected my appetite and the way food tastes. I am surprised I have not lost more weight than I have.
Brain

PCS can cause certain sensations to change. You may become more sensitive to certain smells or tastes and less sensitive to other smells or tastes.

At Brain Injury Support Group last night, there were three people with decreased or no sense of smell.

If anyone has a "sudden" change in smell or taste or other senses, it would be worth calling a doctor to be seen. If is is combined with any other loss of function or motor control, get to the Emergency right away.

mouse1, It sounds like you may have lost that smell sense but not realized it until the spraying started.

My best to you all.

I would say it is reduced rather than lost.
