Brochures and Other Handouts

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

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    
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.

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

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

Once you've signed up for the list, you post by sending an email to 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

Once you've signed up for the list, you can also browse previous posts in the archive at

There is also a mirror of the archive on Yahoo at 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.

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.

Several members have contributed letters which they or their doctors have written in support of accommodation for CSDs. We include them here in case they can be of use to others.
