Childhood Trauma and Risk for Chronic Fatigue Syndrome: Association with Neuroendocrine Dysfunction." Heim, C., Nater, U.M., Maloney, E., Boneva, R., Jones, J.F., & Reeves, W.C.
What did the researchers want the study to determine?
The researchers wanted to determine if there was a correlation between childhood trauma and the eventual development of chronic fatigue syndrome (CFS) by examining neuroscience and looking for evidence related to the pathophysiology of the disease.
Health Outcome of Interest: What health condition did the researchers study?
The researchers studied chronic fatigue syndrome.
Exposure(s) of Interest: What factors did the researchers investigate to determine an association with the outcome listed above? There may be more than one.
Researchers looked at patients with childhood trauma and those with CFS. They looked at the neuroendocrine system including the hypothalamic-pituitary-adrenal axis and other neurodendocrine dysfunctions.
5. Participants: Whom did the researchers study? How many?
113 patients with CFS and 124 control patients were surveyed from a population of 19,381 Georgian resident adults.
6. Study design: What type of epidemiological study design -- observational or experimental -- does the study describe? Why?
This was an experimental study in that measurements of saliva were taken but also observational based upon the surveys returned by the patients.
7. Type(s)/Method(s) of Data Collection: What type(s) or method(s) were used to collect the data for the study? (E.g. questionnaire, medical records)
The study was a survey where participants either with or without CFS were questioned about their current lives as well as past traumas they experienced. This was coupled with examination of the individuals' endocrine systems including taking samples of salvia and testing for cortisol.
8. Results/Main Findings of Study: What were the results of the study? What were the conclusions of the researchers?
Researchers found that those with CFS largely reported having experienced childhood trauma. At the same time, children with concurrent trauma were found to be more likely to develop the condition due to developmental issues relating to the endocrine system.

Enforcement of Psychology Treatment for the Mentally Ill
Psychology Treatment For most of U.S. history up to the time of the Community Mental Health Act of 1963, the mentally ill were generally warehoused in state and local mental institutions on a long-term basis. Most had been involuntarily committed by orders from courts or physicians, and the discharge rate was very low. Before the 1950s and 1960s, there were few effective treatments for mental illnesses like depression, anxiety disorders and

Bipolar Disorder in Children and Adolescents for Education
Juvenile/Child Onset Bipolar Disorder
Diagnoses of bipolar disorder in childhood are rare, even among adolescent populations. One of the reasons why bipolar disorder is infrequently diagnosed is the “symptomatic overlap with attention deficit hyperactivity disorder (ADHD),” (Wozniak, Biederman, Kiely, et al., 1995). Diagnoses are likely dependent on contextual variables, as the psychologist or psychiatrist has leeway when assessing the child. Research on child onset bipolar disorder has evolved, though, to

Stress is one term most people use synonymously with negative experiences they get in life. Negative events in life which confer depression risks, suicide thoughts and behavior, involve interpersonal, traumatic childhood and occupational events. Trauma, mostly childhood trauma, has important
