Purpose: Early-life stress (ELS) has a long-lasting effect on affective function and may entail an increased risk for major depressive disorder (MDD). However, resilience can play a protective role against developing psychopathology. In this study, we investigated the relationships of depressive symptoms with ELS and resilience in MDD.
Materials And Methods: Twenty-six patients with MDD as well as age- and gender-matched healthy controls were included in this study. Each subject was assessed concerning ELS, resilience, and depressive symptom severity with self-report questionnaires. Independent samples t-test and Mann-Whitney test were performed to compare ELS and resilience between the patient and control groups. Spearman correlation analyses and linear regression analysis were conducted to investigate significant ELS and resilience factors associated with depressive symptoms.
Results: In the MDD patient group, subjects reported greater exposure to inter- parental violence, and five factor scores on the resilience scale were significantly lower in comparison to the control group. In linear regression analysis, in regards to resilience, depressive symptom score was significantly associated with self-confidence and self-control factors; however, ELS demonstrated no significant association with depressive symptoms.
Conclusion: Among resilience factors, self-confidence and self-control may ameliorate depressive symptoms in MDD. ELS, including inter-parental violence, physical abuse and emotional abuse, might be a risk factor for developing depression. Assessment of early-life stress and intervention programs for increasing resilience capacity would be helpful in treating MDD.

Background: Mounting evidence suggests that mitochondria respond to psychosocial stress. Recent studies suggest mitochondrial DNA (mtDNA) deletions may be increased in some psychiatric disorders, but no studies have examined early-life stress (ELS) and mtDNA deletions. In this study, we assessed mtDNA deletions in peripheral blood mononuclear cells of medically healthy young adults with and without ELS.

Early life stress (ELS) significantly influences mental health in later stages of life. Yet it is unclear whether recent life events lessen or intensify the effects of ELS on present wellbeing and distress. We addressed this question in 1064 healthy community adults with a normative range of wellbeing and distress.

Purpose: To analyze and interpret why some individuals are resilient to ELS while others are susceptible, resulting in psychiatric outcome later in life, with a focus on the role of DNAm of the gene as a mediating mechanism between ELS and the risk of psychiatric outcomes. We hypothesized that a high level of mental resilience to ELS, expressed as lower incidence of psychiatric outcomes, was associated with attenuated DNAm levels.

Early life stress (ELS) can negatively impact health, increasing the risk of stress-related disorders, such as post-traumatic stress disorder (PTSD). Importantly, PTSD disproportionately affects women, emphasizing the critical need to explore how sex differences influence the genetic and metabolic neurobiological pathways underlying trauma-related behaviors. This study uses the limited bedding and nesting (LBN) paradigm to model ELS and investigate its sex-specific effects on fear memory formation.

Article Synopsis
- Early life stress (ELS) is linked to adult mental disorders like PTSD, with varying effects based on gender and resilience factors.
- The study investigated emotional and cognitive behaviors in rats subjected to different durations of maternal separation (MS) and subsequent prolonged stress (SPS) in adulthood, noting anxiety, depression, and memory deficits.
- Key findings showed that maternal separation affects behaviors differently based on stress exposure duration, with observed changes in telomere length and protein expression that could relate to mechanisms of PTSD.
