So, I've noticed yet another symptom (that coincides with parkinsons). I seem to have a rather dulled sense of smell as of latelly. I can still smell things, but I need to have the source more or less under my nose. For months I've had this feeling of a stuffy nose, without it actually being so. I can't seem to spontaniously smell things anymore. Can this actually be caused by anxiety/depression/ocd/stress, or is parkinsons actually more likelly to be the cause of it?
