1/2. Physical symptoms under forced-phase advance treatment in a patient with delayed sleep phase syndrome: a case report.The physical symptoms that are observed with forced waking in patients with delayed sleep phase syndrome (DSPS) often prevent the successful treatment of patients. Better understanding of these symptoms will assist in providing appropriate treatment in such patients. Herein, a 19-year-old female patient with DSPS is described, in whom headache, fatigue, and dizziness were observed under forced-phase advance treatment. Statistical analysis showed that her headache was dependent on the therapeutic week, and her fatigue was dependent on the period of the day. There was no association between dizziness and either factor. Experience with this patient indicates that the fatigue observed with forced waking is related to the circadian system. This relationship should be explored for other physical symptoms as well.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/2. association between delayed sleep phase and hypernyctohemeral syndromes: a case study.STUDY OBJECTIVE: We investigated whether the hypernyctohemeral syndrome (non-24-hour sleep-wake syndrome) may show a clinical association with the delayed sleep phase syndrome (DSPS) in a 39-year-old woman who developed sleep disturbances following a traumatic brain injury. MEASUREMENTS AND RESULTS: sleep-wake log documentation and wrist-activity recordings for more than 6 consecutive months confirmed the patient's tendency to live on longer-than-24-hour "days." Episodes of relative coordination to the 24-hour day were also noted, suggesting that the patient was transiently in and out of phase with environmental synchronizers too weak to fully entrain her to the geophysical environment. Interestingly, we noted a tendency to initiate sleep between 3:00 am and 5:00 am and wake up from sleep between noon and 1:00 pm. CONCLUSIONS: These results support an association between the hypernyctohemeral syndrome and the DSPS. This association may carry implications for the treatment of circadian rhythms disorders.- - - - - - - - - - ranking = 0.5keywords = physical (Clic here for more details about this article) |
