ANNOUNCING UPCOMING SLEEP STUDIES
IN TOTALLY BLIND INDIVIDUALS

Are you blind with no light perception? Do you have problems sleeping or trouble with daytime sleepiness?

Non-24-hour sleep-wake disorder occurs in some individuals who are totally blind and lack the photic sensitivity necessary to reset the body clock via light exposure. This can lead to problems with sleep and/or daytime excessive sleepiness.

You can help researchers understand non-24-hour sleep-wake disorder by taking a brief phone survey. In addition, you will have the opportunity to be informed of upcoming clinical studies recruiting in your area.

Survey participants need to:

be over 18 years of age

be blind with no light perception

have sleep problems and/or daytime sleepiness

Collected information will be kept strictly confidential.

For each completed survey, a donation of $25 (for a total of up to $50,000) will be made to the American Council of the Blind.

If you want to participate in the survey, please call 1-877-314-5002 Monday-Friday between 9 a.m. and 5 p.m. Eastern time. Thank you!
