Background: Mood disorders involve a complex interplay between multifaceted internal emotional states, and complex external inputs. Dynamical systems theory suggests that this interplay between aspects of moods and environmental stimuli may hence determine key psychopathological features of mood disorders, including the stability of mood states, the response to external inputs, how controllable mood states are, and what interventions are most likely to be effective. However, a comprehensive computational approach to all these aspects has not yet been undertaken.

- SSRIs like sertraline are common medications used to treat depression and anxiety, but researchers want to know how they affect thinking and emotions.
- In a study with 655 participants, they tested how well people learned from their actions while taking either sertraline or a placebo.
- The results showed that sertraline didn't improve task performance as expected, but some changes in learning from mistakes were linked to how people felt after treatment, though the initial predictions were not supported.
Objective: Pharmacologic and behavioral interventions that block reconsolidation of reactivated fear memory have demonstrated only limited success in modifying stronger and long-standing fear memories. Given the efficacy of Eye Movement Desensitization and Reprocessing (EMDR) in treating PTSD, pursuit eye movements are a promising and novel intervention for studies of human memory reconsolidation. Here, we examined the efficacy of pursuit eye movements in interfering with reconsolidation of conditioned fear memories.
View Article and Find Full Text PDFPosttraumatic Stress Disorder (PTSD) is a serious and debilitating condition often associated with significant impairments in daily functioning. To date, research on the complexity of functional impairment in individuals with PTSD is scarce and only limited. Yet, a quantitative synthesis and comprehensive review of existing evidence is needed to better characterize the magnitude of functional impairment in PTSD in distinct domains.

Our objective was to assess feasibility of three designs (preference trial [PCT], randomized controlled trial [RCT], partially randomized patient preference trial [PRPPT]) for a trial comparing planned delivery mode in low-risk women.
Methods: A cross-sectional survey of low-risk, nulliparous pregnant women (N = 416) and healthcare providers (N = 168) providing prenatal care and/or labor/delivery services was conducted in Argentina (2 public, 2 private hospitals).
