: Sleep disturbances are found in a majority of individuals diagnosed with posttraumatic stress disorder (PTSD). The purpose of this literature review is to provide information about PTSD, in addition to assessing sleep quality. Current research observes that the lifetime prevalence of PTSD diagnosis in women is increasing. Although there are several studies that have been conducted to assess PTSD and sleep, there is a gap in the research that pertains to women, PTSD, and sleep quality. The current study will compile information on the subject to aid in decreasing the gender disparity in PTSD research, which is important for treating the entire PTSD population. Using the PubMed and PsycINFO databases, a comprehensive search was conducted to find relevant research about sleep difficulties and PTSD. Sleep disturbances such as insomnia, re-current nightmares, REM sleep dysfunction, and obstructive sleep apnea (OSA) affect sleep quality in PTSD patients. The implications of this study suggest that more research should be conducted pertaining to women and PTSD with sleep difficulties. This research is needed to decrease both PTSD symptoms and sleep-related disorders....

: There is now evidence that depression, as characterized by melancholic symptoms, anxiety, and fatigue and somatic (F&S) symptoms, is the clinical expression of peripheral cell-mediated activation, inflammation and induction of oxidative and nitrosative stress (IO&NS) pathways and of central microglial activation, decreased neurogenesis and increased apoptosis. This review gives an explanation for the multiple "co-morbidities" between depression and a large variety of a) brain disorders related to neurodegeneration, e.g. Alzheimer's, Parkinson's and Huntington's disease, multiple sclerosis and stroke; b) medical disorders, such as cardiovascular disorder, chronic fatigue syndrome, chronic obstructive pulmonary disease, rheumatoid arthritis, psoriasis, systemic lupus erythematosus, inflammatory bowel disease, irritable bowel syndrome, leaky gut, diabetes type 1 and 2, obesity and the metabolic syndrome, and HIV infection; and c) conditions, such as hemodialysis, interferon-α-based immunotherapy, the postnatal period and psychosocial stressors. The common denominator of all those disorders/conditions is the presence of microglial activation and/or activation of peripheral IO&NS pathways. There is evidence that shared peripheral and / or central IO&NS pathways underpin the pathophysiology of depression and the previously mentioned disorders and that activation of these IO&NS pathways contributes to shared risk. The IO&NS pathways function as a smoke sensor that detect threats in the peripheral and central parts of the body and signal these threats as melancholic, anxiety, and fatigue and somatic (F&S) symptoms. The presence of concomitant depression is strongly associated with a lower quality of life and increased morbidity and mortality in medical disorders. This may be explained since depression contributes to increased (neuro)inflammatory burden and may therefore drive the inflammatory and degenerative progression. It is concluded that the activation of peripheral and / or central IO&NS pathways may explain the co-occurrence of depression with the above disorders. This shows that depression belongs to the spectrum of inflammatory and degenerative disorders....
