The American Sleep Association is an organization linking people interested in sleep health and sleep disorders, with a goal to be a complete source of information on sleep.
Their website lets you download a number of lecture videos on subjects like apnea, jetlag and others. It also has a list of sleep centers all across the country and lots of other useful information on support groups, clinical trials and specific disorders.
I found an article about American Sleep Disorder Association - Groups That Are Available To Help.Check it
