Wouldn't the additional production of serotonin because of the lack of reuptake account for hypomanic or mixed state episodes of BPII's on SSRI's and other AD's?

Thanx for reply.

> AM - Here is a good, basic article on the HPA axis role in depression. Keep in mind that several other of the body's systems also interact wiith the HPA axis in modfying mood. As you read the following article, keep in mind this is only one set of chemical reactions and it is linked to several other systems. If you change one component of one system, all of the other systems all respond to this change. We haven't figured out all of the systems that come into play, let alone the ways that these systems can impact on the body's stress system.

This may happen, but I am not sure if it has been proven, especially when taken in the context of all of the other physiological systems involved in such a change.
