Summary

This study looked at how allopregnanolone, a natural brain chemical, affects mood and thinking in perimenopausal women with depression. Researchers gave participants either the drug brexanolone (a form of allopregnanolone) or a placebo to see how it changed their tendency to ruminate. The study was terminated early and only enrolled 2 women, so the findings are very limited.
