The aim of the authors in this study was to evaluate the relationships between perceived perinatal stress and social support to psychological health outcomes in mothers. A longitudinal, quantitative study was conducted in Geneva, Switzerland on 235 primiparous mothers from September 2010 to January 2012. Data were collected between gestational weeks 37 and 41 (T1), 2 days post-delivery (T2), and at 6 weeks postpartum (T3). Perinatal stress was associated with depressive symptoms (R(2) = 0.223), anxiety (R(2) = 0.242), and a low sense of parental self-efficacy (R(2) = 0.21). However, satisfaction with social support moderated the relationship of stress to the health of mothers. In particular, the authors noted that the more women were provided with support from their partners, the less depressive symptoms and elevated levels of anxiety they reported, even under stressful conditions, while the satisfaction of support from their mothers boosted their sense of competency. Furthermore, satisfaction with emotional support from professionals tempered the stress during the post-partum period (∆R(2) = 0.032; p

Objective: The aim of the present study was to identify disease parameters, defensive styles and ego strength measurements associated with various forms of psychiatric complications in patients with multiple sclerosis (MS). Methods: Seventy-nine patients with MS participated in the study and 158 healthy subjects matched for age and sex served as controls. A wide range of clinical information was collected and the following self-report instruments were used: General Health Questionnaire, Symptom Distress Check List, Defense Style Questionnaire, MMPI Ego Strength Scale and Hostility and Direction of Hostility Questionnaire. Results: The odds of being assessed with a psychiatric diagnosis upon interview were 6.7 times greater among patients compared to controls and 9.3 times greater among patients with recent-onset MS compared to patients with long-term disease. Psychiatric complications of MS were closely associated with age of the disease onset and the degree of disability due to MS. Additionally, higher rates of introverted hostility, adoption of maladaptive ego defenses and weakened ego strength were also closely associated with several forms of psychological distress, especially depressive symptoms. Conclusions: MS patients experience elevated symptoms of psychological distress, especially depressive symptoms, which are most closely associated with disease parameters. However, the crucial role of various personality traits such as ego defenses and hostility features in the psychiatric symptom formation also appear to contribute to the development of depressive symptoms. Clinicians involved in the clinical management of patients with MS should identify and modify treatment if these specific personality markers that indicate the exhaustion of the patient's resources to cope with the physical and psychological stress of the illness are present.

Neuroimaging methods can be used to investigate whether sleep disorders are associated with specific changes in brain structure or regional activity. However, it is still unclear how these new data might improve our understanding of the pathophysiology underlying adult sleep disorders. Here we review functional brain imaging findings in major intrinsic sleep disorders (i.e., idiopathic insomnia, narcolepsy, and obstructive sleep apnea) and in abnormal motor behavior during sleep (i.e., periodic limb movement disorder and REM sleep behavior disorder). The studies reviewed include neuroanatomical assessments (voxel-based morphometry, magnetic resonance spectroscopy), metabolic/functional investigations (positron emission tomography, single photon emission computed tomography, functional magnetic resonance imaging), and ligand marker measurements. Based on the current state of the research, we suggest that brain imaging is a useful approach to assess the structural and functional correlates of sleep impairments as well as better understand the cerebral consequences of various therapeutic approaches. Modern neuroimaging techniques therefore provide a valuable tool to gain insight into possible pathophysiological mechanisms of sleep disorders in adult humans.
