Summary

This study compared the sense of smell (odor threshold, discrimination, and identification) between 240 people with bipolar disorder and healthy volunteers. Researchers also looked at brain scans to see if smell performance was linked to brain differences. The goal was to better understand bipolar disorder, not to test a new treatment.
