Polysomnography (PSG) and body temperature were examined in a patient with non‐24 h sleep–wake syndrome who responded to phototherapy. The patient was a 17‐year‐old male who had been suffering from a free‐running sleep–wake rhythm for 2 months. Phototherapy was administered to the patient while he was admitted to our hospital. This treatment immediately changed the free‐running sleep–wake and body temperature rhythm of the patient to the environmental 24‐h rhythm. On a polysomnography, total…

Low-dose valproic acid appears to be one of the effective means of entraining circadian rhythms in patients with non-24-hour sleep–wake syndrome, which in turn likely improves associated depressive symptoms.

The very low “normalization” rate and the large number of patients with ongoing free-run who dropped out suggest that N24SWD is extremely refractory.

Control trials of light or melatonin are lacking in the treatment of non-24 among the sighted, but the use of both may be effective when the patients’ self-selected light/dark schedules are taken into account.

Vitamin B12 (VB12) was administered to two patients suffering for many years from different sleep-wake rhythm disorders, one of which was a 15-year-old blind girl suffering from a free-running sleep- wake rhythm (hypernychthemeral syndrome), and after administration of VB12 at the daily doses of 1.5 mg, the man suffering from delayed sleep phase syndrome was improved.
