Subcallosal Brodmann's Area 25 (Cg25) Deep Brain Stimulation (DBS) is a new promising therapy for treatment resistant major depressive disorder (TR-MDD). While different DBS stimulating parameters may have an impact on the efficacy and safety of the therapy, there is no data to support a protocol for optimal stimulation parameters for depression. Here we present a prospective multi-center double-blind randomized crossed-over 13-month study that evaluated the effects of High (130 Hz) vs Low (20 Hz) frequency Cg25 stimulation for nine patients with TR-MDD. Four out of nine patients achieved response criteria (≥40% reduction of symptom score) compared to mean baseline values at the end of the study. The mean percent change of MADRS score showed a similar improvement in the high and low frequency stimulation groups after 6 months of stimulation (-15.4 ± 21.1 and -14.7 ± 21.1 respectively). The mean effect at the end of the second period (6 months after cross-over) was higher than the first period (first 6 months of stimulation) in all patients (-23.4 ± 19.9 (n = 6 periods) and -13.0 ± 22 (n = 9 periods) respectively). At the end of the second period, the mean percent change of the MADRS scores improved more in the high than low frequency groups (-31.3 ± 19.3 (n = 4 patients) and -7.7 ± 10.9 (n = 2 patients) respectively). Given the small numbers, detailed statistical analysis is challenging. Nonetheless the results of this study suggest that long term high frequency stimulation might confer the best results. Larger scale, randomized double blind trials are needed in order to evaluate the most effective stimulation parameters.

Parents of children with ADHD often experience low marital satisfaction, since the child’s increased susceptibility to maladjustment can affect family dynamics as a whole. Objectives: To explore this association by examining parental stress and parental self-efficacy as two possible mediators. Method: Totally, 182 Israeli parents of children in the first to ninth grades (63 parents of children with ADHD and 119 without) completed parental self-efficacy, marital satisfaction, and parental stress questionnaires. Results: As expected, parents of children with ADHD reported higher parental stress, and lower self-efficacy and marital satisfaction than non-ADHD parents. The association between ADHD parents and marital satisfaction was fully explained by parental stress and self-efficacy, suggesting that personal characteristics and situation appraisal are tapped when facing strain and hardship. Conclusion: These findings provide a window of hope for an otherwise deterministic view of the ADHD-marital dissolution relationship and propose individual and familial interventions that may minimize these damaging effects.

Background: Illness, surgery, and surgical hospitalization are significant stressors for children. Children exposed to such medical events may develop post-traumatic medical syndrome (PMTS, pediatric medical traumatic stress) that could slow their physical and emotional recovery. Objective: This study examined the relationship between the level of parental psychological resilience and the development of PMTS in young children. Method: We surveyed 152 parents of children aged 1–6 who were admitted to the pediatric surgery department. Parents completed questionnaires in two phases. In the first phase, one of the parents completed the Acceptance and Action Questionnaire (AAQ-ll) and the Parental Psychological Flexibility (PPF) Questionnaire. In the second phase, about three months after discharge, the same parent completed the Young Child PTSD (Post Traumatic Stress Disorder) Checklist (YCPC) and the UCLA (Los Angeles, CA, USA) PTSD Reaction Index for DSM-5 Parent/Caregiver Version for Children Age 6 Years and Younger Evaluating Post-traumatic Disorder. In addition, the parent completed a Posttraumatic Stress Diagnostic Scale (PDS) questionnaire to assess the existence of post-traumatic symptoms in the parents. Results: The findings indicate that (1) a parent’s psychological flexibility is significantly associated with the level of personal distress (r = −0.45, p < 0.001), (2) a parents’ level of distress is significantly correlated with the child’s level of PTMS, and (3) a parent’s level of psychological flexibility is a significant mediating factor between the level of parental post-traumatic distress and the child’s level of PTMS. Conclusions: A parent’s psychological flexibility may act as a protective factor against the development of the child’s mental distress after hospitalization or surgery.

After a traumatic medical event, such as surgery or hospitalization, a child may develop a phobia of medical care, sometimes preventing future medical adherence and impairing recovery. This study examined the correlation of Pediatric Medical Traumatic Stress (PMTS) on the development of Medical Phobia (MP) and subsequent treatment adherence. We enrolled 152 parents of children aged 1–6 hospitalized in a surgical ward. During hospitalization, parents completed questionnaires that identified post-traumatic stress symptoms. Four months post hospitalization, parents completed questionnaires on post-traumatic stress, medical phobia, psychosocial variables and medical adherence. We found a positive correlation between PMTS and MP and low adherence to medical treatment. In addition, MP mediated the relationship between PMTS severity and adherence, indicating that PMTS severity is associated with stronger medical phobia, and lower pediatric adherence to medical treatment. Our findings suggest that medical phobia serves as an essential component of PMTS. It is important to add medical phobia to medical stress syndrome definition. In addition, as MP and PMTS are involved in the rehabilitation and recovery process and subsequent success, it is an important aspect of treatment adherence.
