> 'ultradian' really sounds more like a relative of atypical or ADHD than bipolar. i think there is actual chang ein gene expression during switches and buildup of different secondary messangers and chang ein receptor sensitivity. there just isn't time over the course of an hour or two for that.
Still, epidemiologically, ultra-rapid cycling and ultradian cycling between antipodal mood states exist, one of which is mania I can tell you from experience that the switch from one extreme to the other can take as little as 30 minutes. It can be a paroxsymal event. I think we could come up with a few scenarios where whole systems are turned on and off by modulators beginning in the lower brain - where biological clocks reside. Ultra rapid cycling or the rare ultradian cycling are probably phenomena of great complexity including dysregulated feedback loops on several levels.
Don't know.
