Sleep of 6 depressed patients with hypersomnia was studied during their depressed phase and their remitted phase using 24-h polygraphic recording. Nine normal subjects were studied as the controls. The latency to sleep onset of the depressed patients was significantly shorter than that of the remitted patients and that of the control subjects. The total sleep time of the depressed patients was significantly longer than that of the remitted patients as well as that of the controls. This increase in sleep time of the depressed patients was mainly due to the increased sleep in day time. The intervals between sleep onset and start of each sleep stage, the relative percentage of individual sleep stages, REM latency and REM density of the depressed patients were not significantly different from those of the remitted patients. 相似文献

Although menopausal insomnia is of clinical significance, the essential features of this form of disrupted sleep are poorly understood. The aim of the present study was to identify the sleep characteristics of menopausal insomnia by using overnight polysomnography (PSG). Twenty-one subjects with menopausal insomnia (MI) and 13 sex- and age-matched normal control (NC) subjects without sleep complaints took part in the present study. All MI and NC subjects underwent PSG on two consecutive nights. In comparison with NC, MI subjects had non-specific findings such as significantly shorter total sleep time, longer sleep latency, higher wake time after sleep onset, and lower sleep efficiency. As for rapid eye movement (REM) sleep variables, MI subjects had significantly shorter total REM sleep time, fewer numbers of REM sleep periods, longer REM latency, and higher REM density than did the NC subjects. As for the time course of REM density, REM density during the first 3 h period of nocturnal sleep was significantly higher for MI than for NC subjects. Unlike NC subjects, REM density for MI subjects did not tend to rise progressively during nocturnal sleep. The MI subjects had objective evidence of disrupted sleep and the most striking characteristics of this dysfunction were observed in REM sleep variables. The sleep characteristics of MI subjects were found to differ in REM sleep variables from those of patients with major depression (except for REM density). Menopausal insomnia patients appear to be similar to patients with generalized anxiety disorder accompanied by severe sleep disruption. These data lend support to the clinical distinction between menopausal insomnia and insomnia associated with major psychiatric disorders. 相似文献

Overnight polysomnography was performed in 10 subjects with tuberous sclerosis (TS) and partial epilepsy in order to investigate the relationships between sleep organization, sleep disorders and epilepsy. Sleep architecture abnormalities were observed in 9 cases. Compared with ten healthy age-matched controls, the TS group showed a shorter total sleep time, a reduced sleep efficiency, a higher number of awakenings and stage transitions, an increased wake after sleep onset and stage 1 and a decreased REM sleep. Children with seizures showed a more disrupted sleep architecture compared with seizure-free children. Sleep disorders in TS were mainly due to sleep-related epileptic events and were more evident in children who showed large bifrontal or temporal tubers on MRI. 相似文献

Effects of a transdermal nicotine substitution on psychological smoking cessation were investigated in a double-blind prospective study. 131 smokers have been randomly assigned to three treatment conditions: All smokers underwent nine weeks of self-controlled smoking cessation. During 6 weeks one group was additionally treated with nicotine patches continuously releasing nicotine through the skin into the blood circuit. The second group received placebo patches; while the third group was treated with behavioral training alone. Treatment effects were measured by daily cigarette consumption. Follow-up investigations were performed 3, 6 and 12 months after therapy. Nicotine-treated subjects reached significantly higher abstinence rates during and at the end of treatment as well as during the follow-up period, than both placebo- and control-subjects. No severe side effects of plasters have been reported. The results thus indicate good therapeutic effectiveness of transdermal nicotine substitution. 相似文献

Sleep apnoea syndromes have been known since long, and frequently the presenting symptoms are neurological in nature. However, these disorders have not been systematically studied and reported in the Indian literature. Out of 12,000 neurology outpatients seen by authors in 2 years, 60 had primary sleep disturbances. All these 60 patients underwent clinical evaluation and video EEG polysomnography. In 8 out of 60 (13%) patients, sleep apnoea was documented. Five patients had obstructive sleep apnoea, 3 had mixed sleep apnoea and none had pure central sleep apnoea syndrome. Three-fourths of the patients were obese (mean weight 82kg) middle aged males (mean age 46.3 years). The main symptoms encountered were excessive daytime somnolence and snoring. The symptom severity was found to correspond directly with the duration of symptoms as well as obesity. Sleep apnoea syndromes must be seriously considered and documented in all patients complaining of excessive daytime somnolence. 相似文献

Electroencephalogram sleep measures over a 4-week period were obtained on 35 inpatients with major depression (unipolar) who received either fluvoxamine or desipramine in a randomized double-blind trial. Fluvoxamine showed immediate rapid eye movement (REM) sleep suppression and an alerting effect on sleep continuity measures. In contrast, desipramine administration was associated with REM suppression and sleep continuity improvement. The "alerting" quality of fluvoxamine, similar to other serotonergic antidepressants, appears to be unrelated to a lack of clinical efficacy, but may be related to persistent REM sleep suppression. However, it is premature to comment on the serotonin specificity for REM sleep. 相似文献

BACKGROUND: Sleep complaints are common in posttraumatic stress disorder (PTSD) and are included in the DSM criteria. Polysomnographic studies conducted on small samples of subjects with specific traumas have yielded conflicting results. We therefore evaluated polysomnographic sleep disturbances in PTSD. METHODS: A representative cohort of young-adult community residents followed-up for 10 years for exposure to trauma and PTSD was used to select a subset for sleep studies for 2 consecutive nights and the intermediate day. Subjects were selected from a large health maintenance organization and are representative of the geographic area except for the extremes of the socioeconomic status range. The subset for the sleep study was selected from the 10-year follow-up of the cohort (n = 913 [91% of the initial sample]). Eligibility criteria included (1) subjects exposed to trauma during the preceding 5 years; (2) others who met PTSD criteria; and (3) a randomly preselected subsample. Of 439 eligible subjects, 292 (66.5%) participated, including 71 with lifetime PTSD. Main outcomes included standard polysomnographic measures of sleep induction, maintenance, staging, and fragmentation; standard measures of apnea/hypopnea and periodic leg movement; and results of the multiple sleep latency test. RESULTS: On standard measures of sleep disturbance, no differences were detected between subjects with PTSD and control subjects, regardless of history of trauma or major depression in the controls. Persons with PTSD had higher rates of brief arousals from rapid eye movement (REM) sleep. Shifts to lighter sleep and wake were specific to REM and were significantly different between REM and non-REM sleep (F(1,278) = 5.92; P =.02). CONCLUSIONS: We found no objective evidence for clinically relevant sleep disturbances in PTSD. An increased number of brief arousals from REM sleep was detected in subjects with PTSD. Sleep complaints in PTSD might represent amplified perceptions of brief arousals from REM sleep. 相似文献

OBJECTIVE: To evaluate sleep in children with autistic spectrum disorder (ASD) by means of sleep questionnaires and polysomnography; moreover, to analyze their cyclic alternating pattern (CAP). METHODS: Thirty-one patients with ASD (28 males, 3 females, aged 3.7-19 years) and age-matched normal controls were included. ASD children were evaluated by a standard sleep questionnaire that consisted of 45 items in a Likert-type scale covering several areas of sleep disorders and by overnight polysomnography in the sleep laboratory after one adaptation night. RESULTS: The questionnaire results showed that parents of ASD children reported a high prevalence of disorders of initiating and maintaining sleep, enuresis, repetitive behavior when falling asleep, and daytime sleepiness. Polysomnographically, ASD children showed reduced time in bed, total sleep time, sleep period time and rapid eye movement (REM) latency. ASD subjects had a CAP rate during slow-wave sleep (SWS) lower than normal controls, together with a lower percentage of A1 subtypes. CONCLUSIONS: ASD children questionnaires showed a higher percentage of disorders of initiating and maintaining sleep than normal controls; this was not completely confirmed by sleep staging. CAP measures showed subtle alterations of NREM sleep which could be detected with an appropriate methodology of analysis. The reduction of A1 subtypes during SWS might play a role in the impairment of cognitive functioning in these subjects. 相似文献

Twenty-four-hour ambulatory polysomnography was performed in 20 patients with PD who were having visual hallucinations (12 men and 8 women, mean age 70 +/- 6 years). Visual hallucinations were clearly related to daytime NREM sleep or nocturnal REM sleep in 33% of the instances. The data reinforce the hypothesis that neural mechanisms implicated in generating sleep and, in particular, in dream imagery play a role in the occurrence of visual hallucinations in PD. 相似文献

There have been many studies of smoking cessation using nicotine replacement therapy (NRT) with schizophrenic patients, but none exploring the smoking-reduction effects of varying doses of NRT in long-stay patients with schizophrenia. This study aimed to examine the effect of different doses of the nicotine transdermal patch on smoking-reduction and cessation outcomes in long-term hospitalized schizophrenic patients. A total of 184 subjects participated in a randomized, controlled, double-blind 8-week clinical trial. Participants were randomized into two groups using two different doses of NRT: a high-dose NRT group (31.2 mg for the first 4 weeks, then 20.8 mg for 4 weeks, n = 92) or a low-dose NRT group (20.8 mg for 8 weeks, n = 92). The 7-day point prevalence of abstinence was 2.7 % (5/184). Participants in the low-dose NRT group reduced smoking by 3.1 more cigarettes on average than those in the high-dose group (p = 0.005). However, a repeated measures analysis of variance revealed that the main effect of changes in the number of cigarettes smoked, comparing the two types of treatment across periods, was not significant (p = 0.35, partial eta square = 0.018). In summary, among a cohort of chronic institutionalized schizophrenic patients, smoking cessation and reduction outcomes were not correlated with NRT dose, and the cessation rate was much lower than rates in similar studies. It indicates that long-term hospitalized schizophrenic patients have more difficulties with quitting smoking. More effective integrative smoking cessation programs should be addressed for these patients. 相似文献

All-night EEG sleep in 20 anorexics, 10 bulimics, 10 endogenous depressives, and in 10 healthy subjects (all age matched) was compared. In addition, the REM sleep-induction-test was performed in 12 patients with an eating disorder, 7 depressives, and 12 controls by application of the cholinergic agent RS 86. During baseline night, EEG-sleep parameters, especially REM latency, did not differ between the patients and the controls, except for the phasic components of REM sleep (REM density) that were increased in the depressive patients. The frequency of shortened REM latencies, however, was significantly higher in the depressed patients. These observations indicate that in some of the young depressives the disturbance of the REM sleep regulating transmitter system is already present to a similar degree as it is assumed in elderly depressives. After the application of RS 86, REM latency was shortened in all groups under investigation. However, the REM sleep inducing effect of RS 86 was significantly more pronounced in the depressives when compared with both the eating disorder patients and the controls. In the latter two samples, the shortening of REM latency was similar. Furthermore, the eating disorder patients with a concomitant major depression reacted similar to RS 86 as the non-depressed eating disorder patients and the control subjects. Whereas baseline EEG-sleep did not differ significantly among eating disorder patients, young depressives, and healthy subjects, the REM sleep inducing effect of the cholinergic agent RS 86 clearly distinguished between the depressives and both the patients suffering from eating disorders and the controls.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: The aim of this study was to evaluate the sleep breathing patterns and to detect the eventual presence of periodic leg movements (PLMs) in patients affected by Angelman syndrome (AS). METHODS: Ten children with AS were recruited to participate in the study; the clinical diagnosis was confirmed by the genetic analysis (maternal 15q deletion, uniparental paternal disomy, or mutation of the UBE3A gene). All patients but two had presented epileptic seizures. Two age-matched groups of patients with mental retardation (MR) associated (MRE+) or not (MRE-) to epilepsy were used as control groups. All subjects underwent one polysomnographic recording, after one adaptation night. Sleep stages were scored according to standard criteria slightly modified in order to take into account the specific EEG patterns of AS, also the apnea/hypopnea index (AHI) was quantified; PLMs were identified and the PLM index (PLMI) was computed. The statistical analysis was carried out by means of the one-way ANOVA, followed by the Fisher LSD post-hoc test, when appropriate, and by means of the linear correlation coefficient between AHI and PLMI. RESULTS: Sleep macrostructure showed only few significant differences between children with AS and the other two groups of subjects: AS patients showed higher percentage of wakefulness after sleep onset and sleep onset latency; moreover, the percentage of REM sleep was reduced in AS and in MRE+ subjects. A tendency for AS subjects to present a higher PLMI than the other two groups was also found. AHI >5 was found in 30% of AS subjects, in 30.8% of MRE+, and only in 20% of MRE- patients (chi(2) = 2.359, NS); 70% of AS patients, 38.5% of MRE+, and 46.7% of MRE- subjects had PLMI >5 (chi(2) = 3.088, NS). CONCLUSIONS: These results confirm our previous questionnaire-based findings of a high prevalence of sleep breathing disorder and important PLMs in AS and allow us to hypothesize that epilepsy, rather than mental retardation, might exacerbate these sleep disorders. SIGNIFICANCE: Sleep breathing disorder and PLMs might contribute to the cognitive impairment and to the worsening of life quality of subjects with AS and with MR (mostly those with epilepsy). Therefore, our findings suggest the need to explore these sleep disorders in children affected by MR and to set up a correct treatment. 相似文献

Objective/BackgroundMachado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is the most common type of autosomal dominant spinocerebellar ataxia (SCA). Sleep disorders have been described as frequent non-motor symptoms in MJD, and with marked impairment on quality of life. However, few studies have evaluated the frequency and characteristics of sleep apnea in MJD.Patients/MethodsThis study analyzed the prevalence of sleep apnea in 47 patients with MJD by using polysomnography. Clinical variables such as age, age at onset of symptoms, duration of symptoms (at time of evaluation), body index mass, ataxia scales severity and CAG repeat length were compared with polysomnographic findings.ResultsThirty four percent of MJD patients had OSAS, and 42.5% had excessive daytime somnolence. There were no differences considering ataxia severity, CAG repetition length or other clinical variable.ConclusionsPatients with MJD have high frequency of obstructive sleep apnea, and this sleep disorder is not correlated with ataxia severity, CAG repetition length or other clinical variable. 相似文献
