The co-occurrence of insomnia and mental disorders constitutes the most prevalent diagnosis pattern found in sleep disorder clinics. Yet, there remains a paucity of epidemiological information regarding comorbidity of mental disorders and sleep disorder symptomatology in the general population. The present study showed results based on a large(More)
OBJECTIVE This study aims to examine the association between the chronotype (morningness/eveningness) and specific mental disorders. METHODS Cross-sectional epidemiological study conducted in three in-patient clinical settings. A total of 1468 consecutive in-patients who gave their written consent were enrolled. On the admission day, patients filled sleep(More)
INTRODUCTION Irregular work schedules often results in a disruption of the normal circadian rhythm that can causes sleepiness when wakefulness is required and insomnia during the main sleep episode. METHOD Two physicians using the Sleep-EVAL system interviewed 817 staff members of a psychiatric hospital. The interviews were done during the working hours.(More)
Unpredictable endometrial bleeding is the major side-effect of levonorgestrel-releasing s.c. implants (Norplant), otherwise a method of choice for long-term contraception. The mechanisms responsible for bleeding are still unknown and no reliable treatment is available. Several matrix metalloproteinases (MMP) are expressed and activated in human endometrium(More)
The effects of 400-600 mg trazodone on the sleep patterns of ten depressed in-patients treated for 5 weeks were studied during the initial (days 1-3) and terminal (days 26-28) treatment periods. The sleep parameters were compared to those obtained from three sleep recordings performed just prior to the initiation of the treatment and after 2 adaptation(More)
BACKGROUND Disturbance of sleep-wake cycles is common in major depressive disorder (MDD), usually as insomnia, but also as hypersomnia or reduced daytime alertness. Agomelatine, an MT(1) and MT(2) receptor agonist and 5-HT(2C) receptor antagonist, represents a novel approach in MDD, with proven antidepressant efficacy and a positive impact on the sleep-wake(More)
In order to determine whether a decrease in the amplitude of heart rate circadian rhythm (HRCR) could represent a chronobiological marker of depression and to answer the question of the possible role of this alteration in the reduction of rapid eye movement sleep latency (REM latency) observed in depression, 22 major depressed patients (DSM III R,(More)
Heart rate (HR) was continuously monitored during successive 24-hr periods in 19 healthy subjects and 26 major depressed patients (DSM III-R). Recordings were performed after a 2-week wash-out period and the morningness or eveningness typology of each subject was determined. The chronobiological parameters and rhythm percentage (RP) were calculated by the(More)
BACKGROUND Prolonged-release melatonin (PRM) 2 mg is indicated for insomnia in patients aged 55 years and older. A recent double-blind placebo-controlled study demonstrated 6-month efficacy and safety of PRM in insomnia patients aged 18-80 and lack of withdrawal and rebound symptoms upon discontinuation. OBJECTIVE To investigate the efficacy, safety, and(More)
UNLABELLED Radiolabeled ligands of monoamine transporters have already been used to visualize cerebral monoamine innervation by tissue autoradiography and by PET or SPECT in vivo. METHODS A sampling technique was developed to allow for both the autoradiographic counting of serotonin (5-HT) axonal varicosities, labeled by uptake and storage of [3H]5-HT,(More)
