Electrocortical Profiles in Relation to Childhood Adversity and Depression Severity: A Preliminary Report.

Assessment of electroencephalographic (EEG) activity in depression has provided insights into neural profiles of the illness. However, there is limited understanding on how symptom severity and risk factors, such as childhood adversity, influence EEG features. Eyes-closed EEG was acquired in N = 28 depressed individuals being treated in a tertiary psychiatric setting.

Auditory P50 Sensory Gating Alterations in Major Depressive Disorder and their Relationship to Clinical Symptoms.

Cognitive deficits in depression are pervasive and include impairments in attention and higher-order functions but the degree to which low-level sensory processes are affected is unclear. The present work examined event-related potential (P50 and N100) features of auditory sensory gating (i.e.

Single, Repeated, and Maintenance Ketamine Infusions for Treatment-Resistant Depression: A Randomized Controlled Trial.

Objective: Subanesthetic ketamine doses have been shown to have rapid yet transient antidepressant effects in patients with treatment-resistant depression, which may be prolonged by repeated administration. The purpose of this study was to evaluate the antidepressant effects of a single ketamine infusion, a series of repeated ketamine infusions, and prolongation of response with maintenance infusions.

Methods: Forty-one participants with treatment-resistant depression completed a single-site randomized double-blind crossover comparison of single infusions of ketamine and midazolam (an active placebo control).

Weight Status and DSM-5 Diagnoses of Eating Disorders in Adolescents From the Community.

Objective: To estimate jointly the point prevalence of weight and eating disorders in a community sample of adolescents; to investigate psychosocial correlates of thinness, overweight, and obesity, and of full- and subthreshold eating disorders (EDs); and to examine the relationships between weight status and prevalence of EDs.

Method: A total of 3,043 Canadian adolescents (1,254 males and 1,789 females; mean age = 14.19 years, SD = 1.
