Emotional abuse in childhood is a differential factor for the development of depression in adults.

We evaluate the association between subtypes of early life stress (ELS; sexual abuse, physical abuse, emotional abuse, physical neglect, and emotional neglect) and psychiatric disorders in adults. The sample was composed of 81 adult psychiatric patients treated at the Day Hospital Unit in Brazil. The patients were assessed using the Mini International Neuropsychiatric Interview according to diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The presence of ELS was confirmed by the Childhood Trauma Questionnaire, which investigates abuse and neglect subtypes. The patients were also evaluated for the severity of psychiatric symptoms through self-report questionnaires. A total of 71.6% of the patients experienced some type of severe ELS compared with 28.4% of the patients without ELS. Of these, 55.5% reported having experienced emotional abuse; 48.1%, physical neglect; 45.7%, emotional neglect; 39.5%, physical abuse; and 27.2%, sexual abuse. Our data showed that, among the ELS subtypes, emotional abuse was positively associated with psychopathology in adults, particularly with mood disorders (p < 0.05). The patients with a history of emotional abuse had higher severity scores in all symptoms, such as depression, hopelessness, suicidal ideation, anxiety, and impulsivity. These data demonstrate the impact of ELS, especially in cases of emotional abuse, as a trigger for psychiatric disorders and indicate that the severity of ELS is associated with severity of psychiatric symptoms. Therefore, further studies are needed to assess the importance of emotional abuse as a risk factor of severe psychopathology in adults.

Early Life Stress in Depressive Patients: HPA Axis Response to GR and MR Agonist.

BACKGROUND: Evidence indicates that early life stress (ELS) can induce persistent changes in the hypothalamic-pituitary-adrenal (HPA) axis to respond to stress in the adult life that leads to depression. These appear to be related to the impairment of HPA hormones through binding to glucocorticoid (GR) and mineralocorticoid receptors (MR). The aim of this study was to evaluate the impact of ELS in HPA axis response to challenges with GR and MR agonists in depressed patients. METHODS: We included 30 subjects, 20 patients with current major depression (HAM-D21 ≥ 17). Patients were recruited into two groups according to ELS history assessed by the Childhood Trauma Questionnaire (CTQ). The cortisol measures in the saliva and plasma were evaluated after using (at 10:00 p.m.) placebo, fludrocortisone (MR agonist), or dexamethasone (GR agonist). RESULTS: Depressed patients showed a significantly lower salivary cortisol upon waking after placebo compared with controls. Moreover, cortisol awakening responses (CAR) after MR agonist were found to be lower in depressed patients than in controls. With CTQ scores, HAM-D21, body mass index and CAR after placebo, GR agonist, MR agonist we found in a Linear Regression model that depressive patients with ELS (p = 0.028) show differences between placebo vs. MR agonist (R = 0.51; p < 0.05) but not after GR agonist; in depressive patients, without ELS the data show differences between placebo vs. MR agonist (R = 0.69; p < 0.05); but now as well placebo vs. GR agonist (R = 0.53; p < 0.05). CONCLUSION: Our findings indicate that MR activity is impaired in depressed patients compared with controls. Furthermore, in spite of the previous limitations described, in depressed patients with ELS, there was suppression by MR agonist, indicating that patients with ELS are sensitive to MR agonists. In contrast with depressed patients without ELS, we find suppression after both MR and GR agonist. These data suggested that in ELS an imbalance exists between MR and GR with MR dysfunction.

Analysis of the occurrence of early life stress in adult psychiatric patients: a systematic review

The purpose of the paper was to conduct a systematic review of early life stress and its association with psychiatric disorders in adulthood. The occurrence of early stress has lasting negative consequences on the individual, with psychopathology onset one of the most important consequences. The degree of early life stress is associated with the severity of psychiatric disorders and disability in adulthood. Methodology: We conducted a search of two databases (PubMed and SciELO), limited to the time span 1990-2010, using the following keywords: child abuse, maltreatment, early stress, and psychiatric disorders. Thirty-one papers were selected for this review. Results: We found that the subtypes of early life stress such as emotional and physical neglect and sexual, emotional, and physical abuse have associations with several psychiatric disorders, but the Borderline Personality Disorder and Mood Disorders are more associated with the categories listed. Conclusions: Exposure to adversities in childhood and adolescence is predictive of psychiatric disorders in adulthood. More studies are needed to understand the mechanisms by which early life stress is a risk factor for future psychopathology.

Early life stress, HPA axis, and depression

Considerable evidence from various studies suggests a preeminent role for early adverse experiences in the development of psychopathology, especially depression. The most recent studies reviewed herein suggest that early life stressors are associated with an increased risk for mood disorders in adulthood. This review examines the emerging literature on the relationship between stress, hypothalamic-pituitary-adrenal (HPA) axis function, and depression and the role of early life stress as an important risk factor for HPA axis dysregulation. The most consistent findings in the literature show increased activity of the HPA axis in depression associated with hypercortisolemia and reduced inhibitory feedback. Moreover, HPA axis changes appear to be state-dependent, tending to improve upon resolution of the depressive syndrome. Interestingly, persistent HPA hyperactivity has been associated with higher rates of relapse. These studies suggest that an evaluation of the HPA axis during antidepressant treatment may help identify patients who are at a higher risk for relapse. These findings suggest that this dysregulation of the HPA axis is partially attributable to an imbalance between glucocorticoid and mineralocorticoid receptors. Evidence has consistently demonstrated that glucocorticoid receptor function is impaired in major depression, but few studies have assessed the activity of mineralocorticoid receptors in depression. Thus, more studies are needed to elucidate this issue.
