Sex differences in stress-induced sleep deficits.

This study examined sex differences in sleep measures prior to, during and after repeated restraint stress in adult male and female rats. Our data reveal that repeated stress increased time spent awake and decreased slow-wave sleep (SWS) and REM sleep (REMS) in females, and these effects persisted over 2 days of recovery. In contrast, the effects of stress on males were transient. These insomnia-like symptoms were accompanied by a greater number of exaggerated motor responses to waking from REMS in females, a phenotype similar to trauma-related nightmares. In sum, these data demonstrate that repeated stress produces disruptions in sleep that persist days after stress is terminated in female rats. These disruptions in sleep produced by 5 days of repeated restraint may be due to their lack of habituation. PMID: 33525935 [PubMed - as supplied by publisher]

Health staff are suffering severe mental health problems such as panic attacks and having sleepless nights because of the pandemic, according to a survey published today (Thursday) by UNISON. The findings reveal almost half (48%) of health employees​ including nurses, porters, paramedics, healthcare assistants and A&E staff across the UK have struggled to cope. The union says free 24-hour helplines are urgently needed to support those experiencing burnout​, especially as hospital admissions continue to soar.

Conclusion: There were significant improvements in sleep and other clinical indices (depression, PTSD scores) when comparing pre-and post-intervention scores. FIT-IN may be a feasible and practical option in alleviating sleep disturbance in this population. Further studies will be needed to ascertain FIT-IN’s effectiveness.

Many individuals with posttraumatic stress disorder (PTSD) also suffer from insomnia and nightmares, which may be symptoms of PTSD or constitute partially independent comorbid disorders. Sleep disturbances are resistant to current treatments for PTSD, and those suffering from PTSD, insomnia, and nightmares have worse PTSD treatment outcomes. In addition, insomnia and nightmares are risk factors for depression, substance abuse, anxiety, and suicide. Cognitive-Behavioral Therapy for Insomnia and Nightmares (CBT-I&N) and Cognitive Processing Therapy (CPT) for PTSD are first line treatments of these conditions.

Conclusion Researchers are still exploring potential links between PTSD and learning disabilities, but further studies will likely expand on what we know. Understanding how PTSD affects our ability to learn will help treat people with both conditions and lead to better outcomes for these patients.

As a critical care doctor in New York City, Monica is used to dealing with high-octane situations and treating severely ill patients. But she says the COVID-19 outbreak is unlike anything she’s seen before. Over the past few weeks, operating rooms have been transformed into ICUs, physicians of all backgrounds have been drafted into emergency room work, and two of her colleagues became ICU patients. While Monica is proud of her coworkers for rising to the challenge, she says it’s been hard for them to fight a prolonged battle against a deadly, highly contagious illness with no known cure. To make matters worse,...

A causal relationship between sleep disturbances and suicidal behavior has been previously reported. Insomnia and nightmares are considered as hallmarks of posttraumatic stress disorder (PTSD). In addition, patients with PTSD have an increased risk for suicidality. The present article gives an overview about the existing literature on the relationship between sleep disturbances and suicidality in the context of PTSD. It aims to demonstrate that diagnosing and treating sleep problems as still underestimated target symptoms may provide preventive strategies with respect to suicidality. However, heterogeneous study designs, d...

rno R Abstract While evidence-based interventions can help the substantial number of veterans diagnosed with comorbid PTSD and depression, an emerging literature has identified sleep disturbances as predictors of treatment nonresponse. More specifically, predicting effects of residual insomnia and nightmares on postintervention PTSD and depressive symptoms among veterans with comorbid PTSD and depression has remained unclear. The present study used data from a clinical trial of Behavioral Activation and Therapeutic Exposure (BA-TE), a combined approach to address comorbid PTSD and depression, administered to veter...
