Mindfulness-based cognitive therapy for persistent insomnia: a pilot study.

188 gic antidepressant aminpetine, 55% still had at least some type of sexual dysfunction after 6 months compared to 4% in the control group treated with aminpetine alone [13] . More studies are needed to address the frequency, severity and nature of this problem before its neurochemical etiology can be addressed. These case studies have important clinical implications. They suggest that when patients develop sexual dysfunction as a side effect of SSRIs, clinicians should be alert to the possibility that restoration of sexual function may not correlate temporally with medication cessation. Patients are often willing to continue taking SSRIs despite sexual side effects, but the possibility of increasing the probability of dysfunction remaining after discontinuance should be taken into consideration. Such persistent side effects could even worsen the long-term prognosis of depression [14] .

Prevalence, correlates, and predictors of depersonalization experiences in the German general population.

The survey aimed to investigate the prevalence of depersonalization (DP) experiences, its sociodemographic characteristics and its associations with medical conditions, illness behavior, and potential etiologic factors. A representative face-to-face household survey was conducted. The sample consists of n = 1,287 participants aged 14 to 90 years. Sociodemographic variables, medical conditions, current mental disorders, health care utilization, and childhood adversities were assessed. A total of 1.9% participants scored in the range of clinically significant DP (DP-C) and 9.7% reported at least some impairment through DP (DP-I). DP-C/DP-I were strongly associated with depression and anxiety. After adjustment for depression and anxiety, DP-C and DP-I were independently associated with hypertension, diabetes mellitus, chronic pulmonary disease, severe pain, and childhood adversities. We conclude that DP is common, it can not be reduced to a negligible variant of depression or anxiety and that more awareness about DP with respect to detection and research is urgently required.

Sleep Disorders in Spinocerebellar Ataxia Type 2 Patients

Background: Sleep disturbances are common features in spinocerebellar ataxias (SCAs). Nevertheless, sleep data on SCA2 come from scarce studies including few patients, limiting the evaluation of the prevalence and determinants of sleep disorders. Objective: To assess the frequency and possible determinants of sleep disorders in the large and homogeneous SCA2 Cuban population. Methods: Thirty-two SCA2 patients and their age- and sex-matched controls were studied by video-polysomnography and sleep interviews. Results: The most striking video-polysomnography features were rapid eye movement (REM) sleep pathology and periodic leg movements (PLMs). REM sleep abnormalities included a consistent reduction of the REM sleep percentage and REM density as well as an increase in REM sleep without atonia (RWA). REM sleep and REM density decreases were closely related to the increase in ataxia scores, whereas the RWA percentage was influenced by the cytosine-adenine-guanine (CAG) repeats. PLMs were observed in 37.5% of cases. The PLM index showed a significant association with the ataxia score and disease duration but not with CAG repeats. Conclusions: REM sleep pathology and PLMs are closely related to SCA2 severity, suggesting their usefulness as disease progression markers. The RWA percentage is influenced by the CAG repeats and might thus be a sensitive parameter for reflecting polyglutamine toxicity. Finally, as PLMs are sensible to drug treatment, they represents a new therapeutic target for the symptomatic treatment of SCA2.

Waking and dreaming: Related but structurally independent. Dream reports of congenitally paraplegic and deaf-mute persons

Models of dream analysis either assume a continuum of waking and dreaming or the existence of two dissociated realities. Both approaches rely on different methodology. Whereas continuity models are based on content analysis, discontinuity models use a structural approach. In our study, we applied both methods to test specific hypotheses about continuity or discontinuity. We contrasted dream reports of congenitally deaf-mute and congenitally paraplegic individuals with those of non-handicapped controls. Continuity theory would predict that either the deficit itself or compensatory experiences would surface in the dream narrative. We found that dream form and content of sensorially limited persons was indifferent from those of non-handicapped controls. Surprisingly, perceptual representations, even of modalities not experienced during waking, were quite common in the dream reports of our handicapped subjects. Results are discussed with respect to feedforward mechanisms and protoconsciousness theory of dreaming.

[Screening for depersonalization-derealization with two items of the cambridge depersonalization scale].

Depersonalization (DP) and derealization (DR) are considered to be highly underdiagnosed. Therefore the development of screening instruments is important. From the Cambridge Depersonalization Scale (CDS) two items were extracted discriminating best patients with clinical significant DP from patients without DP. These two Items were assembled to a short version of the CDS. This short version (CDS-2) was tested in a sample of 38 patients with clinical significant DP-DR and 49 patients without or only mild DP-DR. Scores were compared against clinical diagnoses based on a structured interview (gold standard). The CDS-2 was able to differentiate patients with clinical significant DP well from other groups (cut-off of CDS-2>or=3, sensitivity=78.9%, specifity=85.7%) and also showed high reliability (Cronbachs alpha=0.92). Therefore the CDS-2 can be considered as a useful tool for screening and identification of DP-DR.

Integration of immigrants into a new culture is related to poor sleep quality.

BackgroundThis article reports on the relationship between cultural influences on life style, coping style, and sleep in a sample of female Portuguese immigrants living in Germany. Sleep quality is known to be poorer in women than in men, yet little is known about mediating psychological and sociological variables such as stress and coping with stressful life circumstances. Migration constitutes a particularly difficult life circumstance for women if it involves differing role conceptions in the country of origin and the emigrant country.MethodsThe study investigated sleep quality, coping styles and level of integration in a sample of Portuguese (N = 48) and Moroccan (N = 64) immigrant women who took part in a structured personal interview.ResultsSleep quality was poor in 54% of Portuguese and 39% of Moroccan women, which strongly exceeds reports of sleep complaints in epidemiologic studies of sleep quality in German women. Reports of poor sleep were associated with the degree of adoption of a German life style. Women who had integrated more into German society slept worse than less integrated women in both samples, suggesting that non-integration serves a protective function. An unusually large proportion of women preferred an information-seeking (monitoring) coping style and adaptive coping. Poor sleep was related to high monitoring in the Portuguese but not the Moroccan sample.ConclusionSleep quality appears to be severely affected in women with a migration background. Our data suggest that non-integration may be less stressful than integration. This result points to possible benefits of non-integration. The high preference for an information-seeking coping style may be related to the process of migration, representing the attempt at regaining control over an uncontrollable and stressful life situation.

Complaints of Sleep Disturbances Are Associated with Cardiovascular Disease: Results from the Gutenberg Health Study

Background Despite their high prevalence, sleep disorders often remain unrecognized and untreated because of barriers to assessment and management. The aims of the present study were to examine associations of complaints of sleep disturbances with cardiovascular disease, related risk factors, and inflammation in the community and to determine the contribution of sleep disturbances to self-perceived physical health. Method The sample consists of n = 10.000 participants, aged 35 to 74 years of a population based community sample in Germany. Cross-sectional associations of complaints of sleep disturbances with cardiovascular risk factors and disease, biomarkers of inflammation, depression, anxiety, and physical health status were analyzed. Results 19% of our sample endorsed clinically significant sleep disturbances. In the unadjusted analyses severity of sleep disturbances increased with female sex, low socioeconomic status, living without a partnership, cardiovascular disease, depression, anxiety, poor physical health, increased levels of C-reactive protein and fibrinogen. After multivariate adjustment robust associations with coronary heart disease, myocardial infarction and dyslipidemia remained. Complaints of sleep disturbances were strong and independent contributors to self-perceived poor physical health beyond depression, anxiety and medical disease burden. Conclusions Given the high prevalence of complaints of sleep disturbances and their strong impact on health status, increased efforts should be undertaken for their identification and treatment.

Association Between Restless Legs Syndrome and Adult ADHD in a German Community-Based Sample.

Objective: Previous research in clinical samples indicated a significant association between ADHD and restless legs syndrome (RLS). The present study examined the association between adult ADHD and RLS in the German population. Method: Self-rating instruments to assess RLS, childhood ADHD, and adult ADHD were administered to a community-based sample (N = 1,632). In addition, current depression and anxiety, sleep disturbances, weight, and height were assessed by self-report. Results: Adult ADHD was associated with statistically significant increases in the odds of meeting diagnostic criteria for RLS even when adjusting for potential confounding variables such as weight (odds ratio [OR] = 3.18, 95% confidence interval [CI] = [1.29, 7.63], p< .001). However, the association did not hold true after adjusting for the presence of sleep disturbances (OR = 2.02, 95% CI = [0.82, 4.96], p = .13). Conclusion: The findings suggest a strong link between RLS and adult ADHD symptoms. Clinicians should be aware of RLS among adult ADHD patients, especially as there might be a negative interactive effect.

Relationship of sleep quality with coping and life styles in female Moroccan immigrants in Germany.

BACKGROUND Epidemiologic studies conducted in Western societies show poorer sleep quality in women compared with men. Socioeconomic and stress-related psychological variables have been shown to influence sleep, but not much is known about sociological and psychological influences on the sleep of women in general and non-Western women in particular. The present study reports on sociodemographic and coping variables in relation to sleep quality in female Moroccan immigrants living in Germany. METHOD Participants took part in a structured personal interview on Pittsburg Sleep Quality Inventory (PSQI) sleep quality, coping style preferences, and information related to the degree of identification with Western life style. RESULTS Sleep quality was poor (PSQI > 6) in 39% of women. Surprisingly, women who had identified with a more Western lifestyle had poorer sleep quality than women who had retained their traditional Moroccan life style. An unusually large proportion of women preferred monitoring (i.e., information-seeking coping style) and adaptive coping (48% and 19%, respectively), regardless of sleep quality. Monitoring was more frequent in women who were less integrated into German culture. CONCLUSIONS Results on sleep quality suggest that for Moroccan immigrant women in Germany, adopting a Western life style may be more stressful than retaining their native life style. The high preference for an information seeking approach in coping may reflect the desire for information rather than actual coping behavior.

Gestörter Schlaf und Schlaflosigkeit

Die Suche nach Erklarungen, warum wir schlafen und warum das Schlafen zeitweise oder uberhaupt nicht gelingt, reicht nachweislich bis in die Antike zuruck. Denn Schlaflosigkeit und Schlafstorungen sind nicht erst ein Phanomen unserer Zeit. Vielmehr haben der Schlaf und insbesondere die qualend erlebte chronische Schlaflosigkeit mit dem damit einhergehenden Gefuhl von Kontrollverlust und Machtlosigkeit schon immer die Menschen beschaftigt und dazu bewogen, den Schlaf erklaren zu wollen und damit auch die Moglichkeit einer Abhilfe zu finden.
