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, Shift Work Disorder, and Jet Lag 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.
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.
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.

We've posted the full presentation on YouTube at youtu.be/21UdTspJyvg. You can also download it from www.circadiansleepdisorders.org/docs/ASBAwebinar.wmv (it's a big file, about 200MB, in .wmv format), and play it on your computer. The text and slides are also posted separately, at www.circadiansleepdisorders.org/docs/ASBAwebinar.pdf (text as a PDF file) and www.circadiansleepdisorders.org/docs/ASBAwebinarSlides.pdf (slides, PDF, 3 MB). And feel free to pass these on to others - we're in the business of raising awareness, after all.
The webinar, by Peter Mansbach (CSD-N president) on Circadian Rhythm Sleep Disorders was broadcast by ASBA (American Sleep and Breathing Academy) on Wednesday, March 19, from 11:30 am - 12:30 pm MDT (Mountain Daylight Time). The talk was targeted for an expected audience of sleep technologists, nurse practitioners, and other medical personnel in hopes of raising awareness of Circadian Rhythm Sleep Disorders, their diagnosis and treatment. Due to technical difficulties on the part of ASBA, the webinar ended just a few minutes after it began, and their attempts to restart it failed.
Circadian Sleep Disorders Network has added its name to the list of organizations supporting the NORD (National Organization of Rare Diseases) position, which opposes the proposed repeal of the orphan drug tax credit. Individuals who wish to support NORD's position may do so here.
Peter Mansbach (CSD-N president - photo at right) attended NORD's Congressional Briefing on this matter on Mar 20, to show support on this issue to the Senate staff members who attended (from the staff of Sen Barrasso and Sen Brown). There were several speakers, including members of the patient community who told their stories.
On January 31, 2014, the FDA approved Hetlioz (tasimelteon) for treatment of non-24 in the blind. Should be available in the spring. I assume it can be used off-label for sighted non-24 people, and possibly even for DSPS. www.hetlioz.com (Vanda Pharmaceuticals). It is supposed to work similarly to melatonin.
NIH has 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 firstname.lastname@example.org, and please copy CSD-N at email@example.com, 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.
Newly elected Board members Asli Kumcu and Andrew Wall joined the CSD-N Board of Directors on Jan 15, 2014. The Board has re-elected Peter Mansbach as president and Beth Macdonald as secretary. Andrew Wall has been elected treasurer. James Fadden remains as interim vice president, until the Board selects a new VP.
Two members are also leaving the Board: James Fadden and Susan Plawsky. We want to thank them for their service. James was a Founding Member, and without his help and encouragement we would not be where we are today. He also wrote the scholarly article on Non-24 that we submitted to NORD and they posted. Susan has been a very responsive Board member, and has helped immeasurably with editing and other advice whenever requested. Both of them will be missed.

Circadian Sleep Disorders Network. Amazon will remeber your selection. But you do have to go to
smile.amazon.com instead of simply amazon.com, for each purchase, if you want 0.5% of that purchase to go to CSD-N. Note that you pay the same amount either way - through Smile the 0.5% goes to us, otherwise it goes to Amazon.

Circadian Sleep Disorders Network has formally affiliated with the Niteowl Email List. What does this mean? CSD-N grew out of this list - the founders of CSD-N "met" on this list, many of our members participate, and we share the same goals. We are also available to assist the list administrator if needed. Nothing about the list's operation will change.

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.)
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:
|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).
|German||DSPS F&A - web||printer|
We also have a one page 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.
We are offering merchandise (mugs, T-shirts, tote bags, bumper stickers, and a messenger bag) with our name and logo through CafePress,
www.cafepress.com/circadiansleepdisordersnetwork. (Note: if you just search CafePress you will find this merchandise, but at a higher price!)
Circadian Sleep Disorders Network is a Coalition Partner of Start School Later. We understand only too well the difficulties many teens have with early school start time, and we support the move to start school later.
We're still getting started!
