Those who are Ultradians

I recognized myself as a very ultra rapid cycler, able to swing one way, then another, sometimes multiple times a day. This is the first time I have seen the term Ultradian. Just stumbled upon it. I am on Lamictal (best mood stabilizer ever - also a low-side effect anti-convusant) and various antidepressants from time to time. The best AD I've ever been on was Desipramine. Curious. I slept very little (5-6 hours a night) and was easily rousable (every time I turned over, I woke up, smiled happily, and went back to sleep in what seemed seconds). I was always well-rested in the morning. However, it causes a lot of of unrelenting dry mouth which is a positive environment for caries. I am Kiwi 22:48, 10 September 2006 (UTC)

Ultra Ultra Rapid Cycling Bipolar Disorder

This term, including the qualifiers "ultra ultra," is not an accidental doubling of words, but how this ultradian manifestation of bipolar disorder is described and defined in the neuropsychiatric and psychiatric literature.

nasal dilatation

i think this should be changed to nasal cycle. Oakleysmith (talk) 02:38, 14 April 2008 (UTC)

Ultradian bipolar disorder

I think that most of the section entitled Ultradian bipolar disorder should be moved to Bipolar disorder. I will probably do that one of these days, if there's no good reason not to. --Hordaland (talk) 17:52, 4 May 2008 (UTC)

The more I think about it, the more I see that so much detail about bipolar does not belong in an article entitled Ultradian. I'm removing these bits, and putting them here, so that others may move them to appropriate articles:

• All forms of bipolar disorder have a defined biological nature, apparently stemming from a common genetic factor that leads to generational morbidity. Twins studies and general population studies show that there is an increased chance of developing a bipolar Disorder when either a general mood disorder or a specific bipolar disorder is present in family members. Further research is being conducted to discriminate any environmental factors that may also play a role in onset and severity of bipolar disorder.
• These oscillations or cycles may last a few days, or even weeks. While current understanding looks to the presence of both states simultaneously, there are anecdotal cases where situational factors can produce distinct and separate periods of depression or mania/hypomania, switching back and forth. Because there is very little research into this particular form of cycling, the terminology is borrowed from the more established research into the formal Bipolar I or Bipolar II categories.
• Ultradian Bipolar Disorder is productively treated by the same mood-stabilizing medications used with Bipolar I and II, though dosing may be difficult due to situational stress and other environmental factors.
• Researchers are working to understand the brain chemistry basis of mood states in an effort to better diagnose and treat bipolar disorder. This research shows the promise of finding biological determinants for Ultradian mood states.

Clarification on correct usage of terms needed

According to both a dictionary of psychology and a dictionary of biology I looked in today (May 16 2009), ultradian rhythms have a longer period than 24 hours, as opposed to infradian rhythms. This information is in Coleman, A. (2001). Dictionary of Psychology. Oxford University Press. Can some one please settle this dispute - after all the article on infradian rhythm has what is almost an edit war going on there. ACEOREVIVED (talk) 20:42, 16 May 2009 (UTC) If you go to this website:

http://www.highbeam.com/doc/1O6-ultradianrhythm.html

You will see that this source also says that ultradian rhythms are those that last longer than a day. ACEOREVIVED (talk) 21:40, 16 May 2009 (UTC)

It is annoying that sources can't agree on what is ultra and what is infra!

Personally, I believe chronobiologist Bora Zivkovic (aka Coturnix) on ScienceBlogs who says in a ClockTutorial: "Seasons of the year, phases of the moon, high and low tides, and alternation between night and day are examples of cyclic changes in the environment. (...) Types of cycles can be circadian (about a day), long-period/low-frequency cycles are infradian (e.g., circalunar, circannual), and short-period/high-frequency cycles are ultradian (e.g., circatidal, circahoral = about an hour)." [8] Thus:

• Infradian cycles have a period longer than a 24-hour day.
• Ultradian cycles have a period shorter than a 24-hour day.

If you'll read the rest of the page you gave the URL for, you'll find these quotes:

• ...Wistar rats, as assessed by in vivo microdialysis, show an ultradian rhythm with a pulse frequency of 1.2 pulses/h.
• The nasal cycle is an ultradian rhythm characterized by alternating patency of the left and right nostrils, with a periodicity of two to eight hours.
• Additionally, an ultradian rhythm of a approximately 12-h period was observed for both rhythms.
• If you're like most people, you're less energetic once every 90 minutes or so for about 10-15 minutes. This 90minute ultradian rhythm (referring to a much shorter cycle than the 24-hour circadian rhythm) influences cognitive function, respiration and movement...

Strangely the definition at the top of the page doesn't agree with the examples given! - Hordaland (talk) 03:12, 17 May 2009 (UTC)

That's an interesting page, thanks. All of its text is from Wikipedia and that is made clear at each section with a (W) button as well as by the attribution at the bottom of the page. --Hordaland (talk) 03:25, 16 February 2015 (UTC)
