Premenstrual Dysphoric Disorder: How to Alleviate Her Suffering Premenstrual dysphoric disorder: How to alleviate her suffering Accurate diagnosis, tailored treatments can greatly improve women’s quality of life pproximately 75% of women experience a premen- strual change in emotional or physical symptoms Acommonly referred to as premenstrual syndrome (PMS). These symptoms—including increased irritability, tension, depressed mood, and somatic complaints such as breast tenderness and bloating—often are mild to moder- ate and cause minimal distress.1 However, approximately 3% to 9% of women experience moderate to severe premen- strual mood symptoms that meet criteria for premenstrual dysphoric disorder (PMDD).2 PMDD includes depressed or labile mood, anxiety, irri- tability, anger, insomnia, difficulty concentrating, and other © IMAGES.COM/CORBIS symptoms that occur exclusively during the 2 weeks before menses and cause significant deterioration in daily func- Laura Wakil, MD tioning.

Welker2, Lindsey A. Beck3, Katherine R. Thorson4, and Richard B. Slatcher5 Abstract Socially anxious people report less closeness to others, but very little research has examined how social anxiety is related to closeness in real-time social interactions. The present study investigated social anxiety, closeness, and cortisol reactivity in zero-acquaintance interactions between 84 same-sex dyads (168 participants). Dyads engaged in either a high or low self-disclosure discussion task and completed self- report measures of closeness and desired closeness post-task. Salivary cortisol was collected before, during, and after the self-disclosure task. Multilevel models indi- cated that in the high self-disclosure condition, individuals higher in social anxiety displayed flatter declines in cortisol than those lower in social anxiety; cortisol declines were not significantly related to social anxiety in the low self-disclosure condition. Further, across both conditions, individual’s social anxiety was associated with decreased levels of closeness and desired closeness, particularly when indi- viduals were paired with partners higher in social anxiety. These findings are dis- cussed in relation to previous work on hypothalamic–pituitary–adrenal function, social anxiety, and interpersonal closeness.

ABSTRACT Insomnia is highly prevalent among asthmatics; however, few studies have investigated insomnia symptoms and asthma development. We aimed to investigate the association between insomnia and the risk of incident asthma in a population-based cohort. Among 17927 participants free from asthma at baseline we calculated odds ratios and 95% confidence intervals for the risk of incident asthma among those with insomnia compared to those without. Participants reported sleep initiation problems, sleep maintenance problems and nonrestorative sleep. Chronic insomnia was defined as those reporting one or more insomnia symptom at baseline and 10 years earlier.

The clinical relevance of such a differentiation is highlighted by findings which suggest distinct responses to pharmacological treatments. Moreover, it has been reported that female patients respond better to selective serotonin re-uptake inhibitors (SSRI) than tricyclic antidepressants. Interestingly, the female predominance among patients with depression seems to be restricted to the atypical subtype. Besides HPA axis activity, distinct alterations of the serotonergic system may also play a critical role for the melancholic and atypical phenotypes, namely a reduced restrained via 5-HT1A autoreceptors in the former and primarily reduced serotonin synthesis in the latter. Moreover, there is evidence for an immune activation in patients with depression, the extent and duration of which may be distinguishable for the melancholic and the atypical subtype.

This progression is associated with worse clinical outcomes and biological changes. Molecular pathways and biological markers of clinical progression have been identified and may explain the progressive changes associated with this disorder. The biological basis for clinical progression in BD is called neuroprogression. We propose that the following intertwined pathways provide the biological basis of neuroprogression: inflammation, oxidative stress, impaired calcium signaling, endoplasmic reticulum and mitochondrial dysfunction, and impaired neuroplasticity and cellular resilience. The nonlinear interaction of these pathways may worsen clinical outcomes, cognition, and functioning. Understanding neuroprogression in BD is crucial for identifying novel Citation: Wollenhaupt-Aguiar, B.; therapeutic targets, preventing illness progression, and ultimately promoting better outcomes.

Recent studies support the notion that metabolic processes correlate with sleep. The study of metabolite biomarkers (metabolomics) in a large-scale manner offers unique opportunities to provide insights into the pathology of diseases by revealing alterations in metabolic pathways. This review aims to summarize the status of metabolomic analyses-based knowledge on sleep disorders and to present knowledge in understanding the metabolic role of sleep in psychiatric disorders. Overall, findings suggest that sleep-wake disorders lead to pronounced alterations in specific metabolic pathways, which might contribute to the association of sleep disorders with other psychiatric disorders and medical conditions. These alterations are mainly related to changes in the metabolism of branched-chain amino acids, as well as glucose and lipid metabolism. In insomnia, alterations in branched-chain amino acid and glucose metabolism were shown among studies. In obstructive sleep apnea, biomarkers related to lipid metabolism seem to be of special importance.

Despite decades of basic and clinical research, our understanding of how benzodiazepines tend to lose their efficacy over time (tolerance) is at least incomplete. In appears that tolerance develops relatively quickly for the sedative and anticonvulsant actions of benzodiazepines, whereas tolerance to anxiolytic and amnesic effects probably does not develop at all. In light of this evidence, we review the current evidence for the neuroadaptive mechanisms underlying benzodiazepine tolerance, including changes of (i) the GABAA receptor (subunit expression and receptor coupling), (ii) intracellular changes stemming from transcriptional and neurotrophic factors, (iii) ionotropic glutamate receptors, (iv) other neurotransmitters (serotonin, dopamine, and acetylcholine systems), and (v) the neurosteroid system.
