Abstract |
Polysomnographic studies in hypersomniac patients with mood disorders are rare. Previous studies investigated patients with a severe mood disorder, but our study was done in patients with dysthymia, who complained of sleepiness. Mean sleep latency test (MSLT) and continuous polysomnographic recording ( CPR) were done in 12 dysthymic patients, in comparison with 12 idiopathic hypersomnia patients, and 12 normal controls. In dysthymic patients mean sleep latency on the MSLT (13 +/- 1) was normal, and when CPR was done during 24 hours, no hypersomnia was found (553 +/- 24). Dysthymic patients showed an abnormal macrostructure of sleep (characterised by an excess of sleep stage I and a decrease of stages 3 and 4), which could be related to their complaint of hypersomnia.
