Abstract
The clinical data of 86 cases of primary circadian rhythm sleep disord er (primary CRSD) were retrospectively examined and compared to 40 cas es of secondary circadian rhythm sleep disorder (secondary CRSD), who had presented with some kind of psychiatric or medical disorder, and h ad exhibited sleep-wake rhythm disorders that were judged to be second ary CRSD based on sleep logs. The comparison of cases found that: (i) the mean age at first presentation to the clinic was significantly you nger for primary CRSD compared to secondary CRSD; (ii) more secondary CRSD cases were unemployed than were Primary CRSD cases; (iii) more ca ses in the secondary CRSD group had a clear trigger for sleep-wake rhy thm disorder onset than cases in die primary CRSD group; and (iv) the types of sleep-wake rhythm disorders in the primary CRSD group consist ed of delayed sleep phase syndrome (DSPS), 72 (83.7%), non-24 pattern, 11 (12.8%), and irregular, 3 (3.5%), In the secondary CRSD group ther e were 25 (62.5%) cases of DSPS pattern, 1 (2.5%) of non-24 pattern an d 14 (35.0%) with irregular pattern. The 56 (65.1%) cases with primary CRSD showed good response to vitamin B12 and bright light therapy, ho wever, 28 (70.0%) cases with secondary CRSD did not respond to such th erapies.
