Someone in r/BipolarReddit asked: How many do you sleep when stable vs (hypo)manic? Depressed?
While this is interesting analysis, I wonder if it's close to the best data we have on this.
Personally as a bipolar person, I can say this definitely correlates with my experience! You could maybe add my experience to the data: + Severe mania - 0-3 hours avg (often in involuntary naps) + Hypomania - 1-5 hours avg (w/ all-nighters) + Elevated/sub-hypomania - 5 hours avg + Stable - 6-8 hours avg + Depressive - 8-10 hours avg + Severe depression - 10-16 hours avg

They defined a Polarity Index value greater than 1.0 as having a relative greater antimanic prophylactic efficacy, whereas a value less than 1.0 would have a relative greater antidepressive efficacy.

Using this data, a large international team was able to pinpoint 114 specific loci – locations in the human genome – that contribute to risk of both schizophrenia and bipolar disorder, and four genome regions that contribute to differences in the biology of the two disorders.
This is exactly what I expected. In fact, I would have been extremely surprised if this weren't the case. I just google "schizophrenia bipolar genes" expecting this result.
I had the thought a few minutes ago, and google it right away. This means that I wasn't able to write it down as a prediction. Nonetheless, I think this points in favor of my prediction abilities. My confidence was inordinately high (i.e. on the order of 90%) even before collecting any evidence. Compare that to other high confidence beliefs (e.g. CFS is caused partly by blood volume), for which I have confidence on the order of 95%, but I have good evidence for that belief. Thus, this instance provides data that my confidence meter is reliable. I'll continue to make an effort to write down predictions ahead of time (to eliminate publication bias).
There are several reasons I suspected this would be the case. Firstly, personal subjective experience; that's what gave me the first inkling. Secondly, the connection of mania with long periods of sleeplessness. If the sleep deprivation causes the mania, then bipolar may be a sleep disorder. This is backed up by the sleep deprivation therapy for depression. Additionally, the connection of depression to sleep disturbance implies that sleep may also be causal in low mood. Furthermore, given that schizophrenia is associated with disrupted sleep spindles, it follows that the two sleep disorders, namely schizophrenia and bipolar, may be closely related genetically (via sleep regulating genes). Moreover, I knew that schizophrenia and bipolar were two of the most heritable psychological conditions; given that both are highly genetic and both involve sleep, it follows that they would likely be closely linked. Finally, I know mania can be associated with delusions, so there are several symptom crossovers. All in all, it is highly surprising that I have not seen this discussed before. Neither documentaries on schizophrenia nor documentaries on manic depression/bipolar have mentioned a link. Nor have studies I've read (admittedly few on this particular topic) mentioned anything of the sort. I shall have to look through the literature to see if this idea has been around for long.
