Our Mission

Circadian Sleep Disorders Network is an independent nonprofit organization dedicated to improving the lives of people with chronic circadian rhythm disorders.

We aim to increase awareness within the medical community and among the general public, to provide emotional support and practical ideas for people living with these disorders, to inform patients and health care providers about treatment options, to encourage research into circadian rhythms, and to advocate for accommodations in education and employment for people with circadian rhythm sleep disorders.

Note that Circadian Sleep Disorders Network is not affiliated with any pharmaceutical, medical device, or other company.

What Are Circadian Rhythm Sleep Disorders?

Circadian Rhythm Sleep Disorders (CRSDs or CSDs) are neurological disorders in which the sleep-wake cycle is out of sync with the day-night cycle. These include in particular Delayed Sleep Phase Disorder and Non-24-Hour Sleep-Wake Disorder. Also included are Advanced Sleep Phase Disorder, Irregular Sleep Wake Disorder, and Shift Work Disorder, which are defined here.

Delayed Sleep Phase Disorder (DSPD), also called Delayed Sleep Phase Syndrome (DSPS), is characterized by an inability to fall asleep until very late at night, with the resulting need to sleep late in the morning or into the afternoon. Questions? See our DSPS Q&A.

Non-24-Hour Sleep-Wake Disorder (Non-24), also called Free-Running Disorder (FRD), is a condition in which a person's day length is significantly longer than 24 hours, so that sleep times get later each day, cycling around the clock in a matter of days or weeks. Questions? See our Non-24 Q&A.

Some people use the term reverse sleep, referring to the fact that sometimes people with DSPD and Non-24 end up sleeping during daylight and being awake at night.

Please refer to our descriptions, definitions, and treatments pages for more details, and print out our brochure, fact sheet, and/or Q&A documents to give to others.

Become a Member! or Renew Now!

We can progress toward our mission of promoting awareness and accommodation only if we can demonstrate that we represent a community of people who suffer from these disorders. Please join now, so we can better help you and the CSD community in achieving our common goals. Together we have a voice! More details are on the Join page.

Last year's members: if you haven't renewed yet, please do so now. Renew now!

We are a 501(c)(3) organization based in the U.S., serving the global circadian sleep disorders community. We are a patient organization, entirely supported by member dues and contributions. We are all unpaid volunteers.

Help Us Spread Awareness

image of brochure cover We are asking our members and followers to give our brochure, and/or our Q&A booklets, to their sleep doctor and their general doctor on their next visits. It is vital to all of us suffering from circadian disorders that more doctors and their support staff understand these disorders and how disruptive they can be. The more doctors who know about us, the more patients we can reach, inform, and support. And the larger our membership, the more credible our voice on behalf of all people with circadian sleep disorders.

You can print out the brochure on US letter paper (8½x11) or on A4 paper (non--US). Booklets can be printed for DSPS or for Non-24 (the same file can be printed on either US or A4 paper). Alternatively you can email us at to request a printed copy of any or all these documents (please specify which). Be sure to include your name and full postal address. We will send these at no charge to you.

CSD-N Board Events now on Google Calendar

The calendar of regular CSD-N Board events has been migrated to a Google Calendar. Members can view the calendar here. You can also add it to your own Google calendar by clicking on the blue "+" sign at the bottom of the page.

Election of Officers

The Board of Directors of Circadian Sleep Disorders Network has elected its officers:

Officers are elected to serve a two-year term. We appreciate the work these volunteers do.

Elections for the Board of Directors concluded in December. The board welcomes newly elected board member Lily Style. Re-elected were Asli Kumcu, Beth Macdonald, and Peter Mansbach. Thanks to all who ran and all who voted.

3-Minute Video Introductions to CRSDs

day-night circle We created and posted a series of 3-minute videos introducing Circadian Rhythm Sleep Disorders:

  1. What Are Circadian Rhythms?
  2. What Are Circadian Rhythm Sleep Disorders?
  3. What Is Delayed Sleep Phase Disorder?
  4. What Is Non-24-Hour Sleep-Wake Disorder?
  5. Urgent Need For Awaraeness And Accommodation
These are also collected into a single playlist.

Circadian Rep Attends SDRAB

Thanks to Susan Plawsky for representing Circadian Rhythm Sleep Disorders at today's (Dec 11) meeting of the NIH Sleep Disorders Research Advisory Board (SDRAB). Susan was formerly on the Board of Directors of the Circadian Sleep Disorders Network. The SDRAB will be revising the NIH Sleep Disorders Research Plan. Susan volunteered to co-chair the working group on Sleep and Circadian Disorders, focusing on treatment.

A DSPD Story Publicized

Our president's story with DSPD was recently featured in the Re-Timer blog, . Re-Timer also included a link to the CSD-N website. Re-Timer is an Australian company that makes a visor for light therapy. (Note: CSD-N makes no recommendations for or against specific companies or devices, but simply lists several on our Treatments page.)

Can Chronotherapy Cause Non-24?

James Fadden, our vice president, has written up the arguments supporting our concern that chronotherapy (delaying the clock) may lead to Non-24-Hour Sleep-Wake Disorder. www.circadiansleepdisorders.org/info/N24chrono.php.

Non-24 Calculator

We've created a new calculator, that predicts both wake times and sleep times into the future, for people with non-24 with a consistent delay. It's at www.circadiansleepdisorders.org/info/N24calc.php.

calculator Let us know ( ) immediately if there are any errors. Suggestions for improvements are also welcome. (Note: the third-party calculator we previously linked to had some serious bugs)

CSD-N Maintains List of Doctors

Find a Doctor! Circadian Sleep Disorders Network is now hosting the "Find a Doctor" page, a list of doctors that patients with DSPD or Non-24 found knowledgeable and helpful. www.circadiansleepdisorders.org/info/doctors.php.

The information was originally assembled in a wiki by several of our members, from comments sent in by patients. CSD-N was invited to take over maintenance of this page. We believe this can be a useful resource for people looking for a doctor knowledgeable about DSPD and Non-24.

Note that we simply post recommendations we receive from patients. We do not have first-hand knowledge of these doctors, and cannot be held responsible for bad recommendations or errors in posted information.

Let us know if you have additional doctors whom you feel are knowledgeable and helpful regarding CRDs.

Write NIH To Add CRSDs To Their Website

NIH has still not included DSPD or Non-24 on their website!

The U.S. National Institutes of Health (NIH) has a number of web pages which talk about sleep disorders. In all these pages we see sleep apnea, narcolepsy, and restless legs; but we do not see any Circadian Rhythm Sleep Disorders - no Delayed Sleep Phase Disorder, no Non-24-Hour Sleep-Wake Disorder. It's no wonder people haven't heard of these disorders, and many doctors still don't recognize how serious they are....

Instructions and sample email are at www.circadiansleepdisorders.org/docs/campaigns/NIHWeb.php . Send email to twerym@nhlbi.nih.gov, and please copy CSD-N at csd-n-news@csd-n.org, so we can follow up, possibly including contacting higher ups.


I received this email from the NIH NHLBI Health Information Center in response to the above campaign. It represents good progress. Dr Twery took action in response to our emails by raising the issue with the Information Center. He passed the emails on to them, and they are aware of our issues. He did advise me that it's a slow process, and will take a long time. In my opinion, it would still help if more people wrote to him, since we are competing for very limited funds. Together we have a voice! Thank you.

More About Us

Niteowl Email List

This is a free mailing list support group for people with DSPS and Non-24 to share their experiences. It's a good place for people just discovering these disorders to hear how others deal with them, as well as for long-time participants to get support and to provide support to others. There are often discussions of evolving treatment, useful to all. For further information, and to sign up, go to www.circadiandisorders.org/list.

Note that membership in Circadian Sleep Disorders Network and membership on this email list are completely separate.

Affiliation

Circadian Sleep Disorders Network is affiliated with this email list, and our volunteers assist the list administrator with some chores. CSD-N was formed by participants on this list, and many of our members post regularly. But we have no control over what appears or who can join, and list membership is completely separate from membership in CSD-N.

Posting

Once you've signed up for the list, you post by sending an email to niteowl@circadiandisorders.org. Everyone on the mailing list receives that post as an email, and you receive everyone else's posts as emails. If you don't like to get separate emails, you can opt to receive in digest form, typically one email a day containing all the day's posts. You make that selection (after signing up) by logging in at www.circadiandisorders.org/list.

Rules

There are some rules:
The rules that the list software enforces are

One frequent problem is that people with more than one e-mail account try to send from an address that isn't registered as a member here. An infrequent problem is that a few e-mail providers aren't accepted at all so another e-mail account must be (acquired and) used. gmail generally works well.

An additional rule is PLEASE do not just reply to a message with a subject line containing "Niteowl Digest, Vol xxx, Issue xxx". That is obviously not informative and if you aren't careful you may include the whole list of messages in the Digest, making your message too large for the list.

Digest or not, it is a good idea to trim whatever you are replying to leaving just enough for people to know what you are replying to.

Of course, don't be snippy or insulting, and please take off-topic conversations off-list. And no advertising.

Archives

Once you've signed up for the list, you can also browse previous posts in the archive at
lists.circadiandisorders.org/private.cgi/niteowl-circadiandisorders.org/.

There is also a mirror of the archive on Yahoo at https://groups.yahoo.com/neo/groups/nite-owl/info. This is useful when the primary archives are not working, as sometimes happens. Login to your Yahoo account, or create one (free) - link is at the top right on that page. Then you have to Join the Yahoo copy of the list - this is separate from signing up for the list itself - there is a button on the Yahoo page to do this.

Our Brochure

image of brochure cover Our brochure is geared to the general public, to introduce DSPS and Non-24 to people experiencing symptoms of these disorders, and to their families. Please distribute it to anyone who may be interested. Print on lightly colored paper for some color, if you like. We used ivory.

Brochure - web display     Print on US letter size paper, PDF
Print on A4 size paper, PDF

The web display version shows the brochure panels in easy-to-read order. The print versions are meant to be printed out on both sides of a sheet of paper, then folded in thirds, creating a brochure. (In the print version, the panels will appear out of order on-screen.)

Our Q&A Documents (FAQs)

We have posted documents describing DSPS and Non-24, in an easy to read Question-and-Answer format. These are designed to give to family members, friends, employers, and school personnel, to help them understand these disorders. Feel free to print and distribute these. There are two different (but similar) versions, one for DSPS and the other for Non-24:

DSPS Q&A - web     printer     booklet*
Non-24 Q&A - web     printer booklet*

The web formats display nicely in your browser. The printer versions are formatted by your browser for printing a multi-page document. The booklet forms are pre-formatted PDF files that you can print on two sides of a single sheet of paper, which then folds in half into a booklet.
* When printing the booklet, be sure to flip on the short edge (select this option if you have a double-sided printer).

In Other Languages:

Spanish:     DSPS Preguntas y Respuestas - web     printer    
     No-24 Preguntas y Respuestas - web     printer    
German:     DSPS F&A - web     printer    

Our Basic Fact Sheet

We also have a one page Basic Fact Sheet that introduces DSPS and Non-24 to people who don't know about them. It's a quick and easy read, just the basics.

CSD-N Merchandise

CSD-N mug We are offering merchandise (mugs, T-shirts, tote bags, bumper stickers, and a messenger bag) with our name and logo through CafePress, at

Websites Link to CSD-N

We have asked other sleep- and health-related web sites to add a link to the CSD-N website, so interested people could learn more about circadian sleep disorders. That also helps our search ranking, making it easier for others to find us. Sites which have linked to us include:

In addition, circadiandisorders.org, which was no longer being maintained, now forwards their traffic to us.

You can help: email other websites with a request to link to Circadian Sleep Disorders Network at www.CircadianSleepDisorders.org. Please use this primary address when suggesting links, not the shortcut.
