Mine got worse in the 40's, but now in my 50's it is much improved. Much of that I attribute to successful therapy to deal with comorbid PTSD issues that complicated my bipolar issues and to gain a great many skills for being more proactive about prevention and early intervention on my part that thus far has helped keep my symptoms from becoming full-blown episodes of depression or hypomania.

I grew up around two women who had bipolar disorder who were much more stable in their later years, and I have a good friend who is older than me who is also more stable now than she was even a decade ago. I seem to experiencing the same thing. I wonder what the hormonal changes have to do with changes in bipolar symptoms?
