Childhood adversities are different in Schizophrenic Spectrum Disorders, Bipolar Disorder and Major Depressive Disorder

Abstract

BackgroundResearch has shown that a history of childhood adversities is common in patients with psychiatric disorders but few studies have investigated links between specific types of adversity and specific psychiatric disorders.MethodsWe investigated the frequency of early childhood adversities in a sample consisting of 91 patients with diagnosis of schizophrenic spectrum disorders (SSD), 74 patients with bipolar disorder (BD), 83 patients with major depressive disorder (MDD) and 85 healthy controls and sought to identify adverse early childhood life events that predict the development of major psychiatric disorders. The Childhood Experiences of Care and Abuse questionnaire was used to collect data on traumatic experiences occurring before the age of 17 years and comprehensive demographic data were also collected. The data were analyzed with chi-squared tests, t-tests, post-hoc and logistic regression.ResultsMaternal absence/loss and economic difficulties in the early life were more prevalent in the BD group than other groups. Escape from home, cannabis abuse, psychological abuse, physical abuse and loneliness were more frequent in the SSD group than in other groups. Paternal absence, neglect of core needs, serious familial tension and absence of adult and peer confidants were all less common in the HC group than in the other groups. The regression model confirmed that different types of adversities play a crucial role in the development of the three investigated disorders.ConclusionsOur results support that SSD, BD and MDD are associated to different childhood adversities. This suggests that psychosocial interventions that reduce the incidence of these early life adversities might reduce the incidence of severe and disabling psychiatric disorders.Electronic supplementary materialThe online version of this article (10.1186/s12888-018-1972-8) contains supplementary material, which is available to authorized users.

The process of stigma experience in the families of people living with bipolar disorder: a grounded theory study

“…Some changes occur in the families of people living with bipolar disorder that cause other family members to be unable to reach their maximum potential in different areas. Stigma experienced in these families can have adverse consequences, such as feelings of shame and frustration, distance from others, and being exposed to injustice and discrimination [21,22]. Numerous studies have shown that 40% of families hide their patients' hospitalization from others, and the fear of being stigmatised is considered the most critical and significant obstacle for patients and their families to benefit from medical services and social support [23][24][25].…”

Clinical Severity and Calcium Metabolism in Patients with Bipolar Disorder

“…Fourth, the CTQ total score is also associated with higher PTH levels. Childhood traumas increase the lifetime risk to develop BD [ 47 ] and are associated with a greater clinical severity [ 48 ] and a more severe clinical course (i.e., rapid cycling, early age of onset, suicide attempts and more depressive episodes) [ 49 ]. In BD patients, a history of childhood trauma leads to difficulties in affective regulation, impulse control, cognitive functioning and neurobiological modifications due to the epigenetic consequences of early trauma.…”

How Does the Parents-related Factors Exacerbate and Improve Schizophrenia?

“…Frontiers in neuroscience [29], found that patients with schizophrenia had higher scores for emotional neglect and physical neglect, and lower utilization scores for physical abuse and subjective support. Bruni [30] refined the types of childhood trauma, and proposed that among the types of childhood trauma suffered by schizophrenia patients, cannabis abuse, loneliness, running away from home, mental abuse, physical abuse and schizophrenia are more related.…”
