Disturbed Sleep Connects Symptoms of Posttraumatic Stress Disorder and Somatization: A Network Analysis Approach
Posttraumatic stress disorder (PTSD) and physical health problems, particularly somatic symptom disorder, are highly comorbid. Studies have only examined this coâoccurrence at the disorder level rather than assessing the associations between specific symptoms. Using network analysis to identify symptoms that act as bridges between these disorders may allow for the development of interventions to specifically target this comorbidity. We examined the association between somatization and PTSD symptoms via network analysis. This included 349 traumaâexposed individuals recruited through the National Centre for Mental Health PTSD cohort who completed the ClinicianâAdministered PTSD Scale for DSMâ5 and the Patient Health Questionnaireâ15. A total of 215 (61.6%) individuals met the DSMâ5 diagnostic criteria for PTSD. An exploratory graph analysis identified four clusters of densely connected symptoms within the overall network: PTSD, chronic pain, gastrointestinal issues, and more general somatic complaints. Sleep difficulties played a key role in bridging PTSD and somatic symptoms. Our network analysis demonstrates the distinct nature of PTSD and somatization symptoms, with this association connected by disturbed sleep
Consolidation/reconsolidation therapies for the prevention and treatment of PTSD and re-experiencing : a systematic review and meta-analysis
Translational research highlights the potential of novel 'memory consolidation/reconsolidation therapies' to treat re-experiencing symptoms and post-traumatic stress disorder (PTSD). This systematic review and meta-analysis assessed the efficacy of so-called memory consolidation/reconsolidation therapies in randomised controlled trials (RCTs) for prevention and treatment of PTSD and symptoms of re-experiencing in children and adults (PROSPERO: CRD42020171167). RCTs were identified and rated for risk of bias. Available data was pooled to calculate risk ratios (RR) for PTSD prevalence and standardised mean differences (SMD) for PTSD/re-experiencing severity. Twenty-five RCTs met inclusion criteria (16 prevention and nine treatment trials). The methodology of most studies had a significant risk of bias. We found a large effect of reconsolidation interventions in the treatment of PTSD (11 studies, nâ=â372, SMD: -1.42 (-2.25 to -0.58), and a smaller positive effect of consolidation interventions in the prevention of PTSD (12 studies, nâ=â2821, RR: 0.67 (0.50 to 0.90). Only three protocols (hydrocortisone for PTSD prevention, Reconsolidation of Traumatic Memories (RTM) for treatment of PTSD symptoms and cognitive task memory interference procedure with memory reactivation (MR) for intrusive memories) were superior to control. There is some emerging evidence of consolidation and reconsolidation therapies in the prevention and treatment of PTSD and intrusive memories specifically. Translational research should strictly adhere to protocols/procedures describing precise reconsolidation conditions (e.g. MR) to both increase the likelihood of positive findings and more confidently interpret negative findings of putative reconsolidation agents

Can children with developmental coordination disorder adapt to task constraints when catching two-handed?
Purpose. To compare the nature and extent of inter and intralimb coupling during two-handed catching and the effect of manipulating task constraints in children with Developmental Coordination Disorder (DCD) and their typically developing peers (AMC).Method. Twenty children aged 7 â 10 years, ten with DCD and 10 AMC attempted to catch a ball ten times in condition 1 (C1), ball to the midline; condition 2 (C2), ball to the left shoulder and condition 3 (C3), ball to the right shoulder. Both 3D kinematic data and video data were collected.Results. Children with DCD caught fewer balls than the AMC children, regardless of age or condition (p ? 0.001). Children with DCD demonstrated a higher degree of linkage between limbs in C1 and a lower degree of between limb coupling in C2 and C3 when compared to the AMC (p ? 0.05). Differences between the AMC7 â 8 and AMC9 â 10 group were found with respect to interlimb coupling.Conclusions. The influence of manipulating task constraints and the individual nature of children with DCD must be considered by those involved in rehabilitation. By doing so, children with DCD may search for appropriate motor solutions to many functional movement tasks required for everyday life
