I googled schizophrenia + detecting odors
I'll put down what one site said.
Behavioral studies of olfaction have demonstrated impairments in the ability to detect and identify odors in patients w/schizophrenia.
Conclusion of test: These data (which I didn't write down , too long) indicate the presence of a primary physiologic impairment in the olfactory cortex underlying behavioral olfactory deficits seen in patients with schizophrenia.
This is consistent with postmortem and in vitro studies suggesting abnormalities in olfactory receptor neurons. Understanding the nature of these physiologic olfactory impairments could offer clues to the basic neuropathology of this disorder.
I just found it interesting. Maybe the dr at CC had it with me thinking I had parkinsons and let me smell some nasty doggy poo poo smell!!
