OBJECTIVE: DNA methylation has been proposed as an epigenetic mechanism by which early-life experiences become "embedded" in the genome and alter transcriptional processes to compromise health. The authors sought to investigate whether early-life victimization stress is associated with genome-wide DNA methylation. METHOD: The authors tested the hypothesis that victimization is associated with DNA methylation in the Environmental Risk (E-Risk) Longitudinal Study, a nationally representative 1994-1995 birth cohort of 2,232 twins born in England and Wales and assessed at ages 5, 7, 10, 12, and 18 years...

OBJECTIVE: The antidepressant escitalopram is predominantly metabolized by the polymorphic CYP2C19 enzyme. The authors investigated the effect of CYP2C19 genotype on exposure and therapeutic failure of escitalopram in a large patient population. METHOD: A total of 4,228 escitalopram serum concentration measurements from 2,087 CYP2C19-genotyped patients 10-30 hours after drug intake were collected retrospectively from the drug monitoring database at Diakonhjemmet Hospital in Oslo...

OBJECTIVE: To understand the role of depressive symptoms in preclinical Alzheimer's disease, it is essential to define their temporal relationship to Alzheimer's proteinopathies in cognitively normal older adults. The study objective was to examine associations of brain amyloid beta and longitudinal measures of depression and depressive symptom clusters in a cognitively normal sample of older adults. METHOD: A total of 270 community-dwelling, cognitively normal elderly individuals underwent baseline Pittsburgh compound B (PiB) positron emission tomography (PET) measures of cortical aggregate amyloid beta and annual assessments with the 30-item Geriatric Depression Scale (GDS)...

OBJECTIVE: The authors assessed the efficacy of trauma memory reactivation performed under the influence of propranolol, a noradrenergic beta-receptor blocker, as a putative reconsolidation blocker, in reducing symptoms of posttraumatic stress disorder (PTSD). METHOD: This was a 6-week, double-blind, placebo-controlled, randomized clinical trial in 60 adults diagnosed with long-standing PTSD. Propranolol or placebo was administered 90 minutes before a brief memory reactivation session, once a week for 6 consecutive weeks...

OBJECTIVE: Genetic variation within the hypothalamic-pituitary-adrenal (HPA) axis has been linked to risk for depression and antidepressant response. However, these associations have yet to produce clinical gains that inform treatment decisions. The authors investigated whether variation within HPA axis genes predicts antidepressant outcomes within two large clinical trials. METHOD: The test sample comprised 636 patients from the International Study to Predict Optimized Treatment in Depression (iSPOT-D) who completed baseline and 8-week follow-up visits and for whom complete genotyping data were available...

Kenneth S Kendler, Eric J Engstrom
Emil Kraepelin's psychiatric nosology, proposed in the 5th and 6th editions of his textbook published in 1896 and 1899, did not quickly gain worldwide acceptance, but was instead met with substantial and sustained criticism. The authors review critiques of Kraepelin's work published in his lifetime by Adolf Meyer, Friedrich Jolly, Eugenio Tanzi, Alfred Hoche, Karl Jaspers, and Willy Hellpach. These critics made six major points. First, Kraepelin's new categories of dementia praecox and manic-depressive insanity were too broad and too heterogeneous...

OBJECTIVE: Research in both animals and humans indicates that cannabidiol (CBD) has antipsychotic properties. The authors assessed the safety and effectiveness of CBD in patients with schizophrenia. METHOD: In an exploratory double-blind parallel-group trial, patients with schizophrenia were randomized in a 1:1 ratio to receive CBD (1000 mg/day; N=43) or placebo (N=45) alongside their existing antipsychotic medication. Participants were assessed before and after treatment using the Positive and Negative Syndrome Scale (PANSS), the Brief Assessment of Cognition in Schizophrenia (BACS), the Global Assessment of Functioning scale (GAF), and the improvement and severity scales of the Clinical Global Impressions Scale (CGI-I and CGI-S)...

OBJECTIVE: Although patients with schizophrenia exhibit impaired suppression of the P50 event-related brain potential in response to the second of two identical auditory stimuli during a paired-stimulus paradigm, uncertainty remains over whether this deficit in inhibitory gating of auditory sensory processes has relevance for patients' clinical symptoms or cognitive performance. The authors examined associations between P50 suppression deficits and several core features of schizophrenia to address this gap...

OBJECTIVE: Pharmacotherapy to rapidly relieve suicidal ideation in depression may reduce suicide risk. Rapid reduction in suicidal thoughts after ketamine treatment has mostly been studied in patients with low levels of suicidal ideation. The authors tested the acute effect of adjunctive subanesthetic intravenous ketamine on clinically significant suicidal ideation in patients with major depressive disorder. METHOD: In a randomized clinical trial, adults (N=80) with current major depressive disorder and a score ≥4 on the Scale for Suicidal Ideation (SSI), of whom 54% (N=43) were taking antidepressant medication, were randomly assigned to receive ketamine or midazolam infusion...

Recent research has linked age-related hearing loss to impaired performance across cognitive domains and increased risk for dementia diagnosis. The data linking hearing impairment to incident late-life depression are more mixed but suggest that diminished hearing does increase risk for depression. Behavioral mechanisms may explain these associations, such as the withdrawal of older adults from situations in which they may have difficulty hearing and communicating, which may contribute to the development of social isolation, loneliness, and consequent cognitive decline and depression...

OBJECTIVE: The authors sought to characterize the symptoms of patients later hospitalized for psychotic disorders in primary mental health outpatient settings, and to investigate whether these symptoms can be used to predict later onset of psychotic illness. METHOD: This was a population-based historical prospective cohort study using national registers of clinical psychiatric services. The sample (N=114,983) comprised 18- to 21-year-olds serving in the Israeli military and examined in military mental health outpatient clinics across 72 consecutive months...

OBJECTIVE: Depression is associated with an increased risk of Alzheimer's disease. Research has shown that the selective serotonin reuptake inhibitor (SSRI) citalopram decreases amyloid-β generation and plaque load. The authors evaluated the impact of SSRI treatment on CSF biomarkers and progression from mild cognitive impairment (MCI) to Alzheimer's dementia. METHOD: Data sets from 755 currently nondepressed participants from the longitudinal Alzheimer's Disease Neuroimaging Initiative were evaluated by Kaplan-Meier analysis and analyses of variance and covariance with ApoE4 status and age as covariates...

OBJECTIVE: Neuroimaging studies show structural differences in both cortical and subcortical brain regions in children and adults with autism spectrum disorder (ASD) compared with healthy subjects. Findings are inconsistent, however, and it is unclear how differences develop across the lifespan. The authors investigated brain morphometry differences between individuals with ASD and healthy subjects, cross-sectionally across the lifespan, in a large multinational sample from the Enhancing Neuroimaging Genetics Through Meta-Analysis (ENIGMA) ASD working group...

The arrival of the Journal's 175th anniversary occurs at a time of recent advances in research, providing an ideal opportunity to present a neurodevelopmental roadmap for understanding, preventing, and treating psychiatric disorders. Such a roadmap is particularly relevant for early-childhood-onset neurodevelopmental conditions, which emerge when experience-dependent neuroplasticity is at its peak. Employing a novel developmental specification approach, this review places recent neurodevelopmental research on early childhood disruptive behavior within the historical context of the Journal...

OBJECTIVE: Adolescence is a developmental stage in which the incidence of psychiatric disorders, such as anxiety disorders, peaks. Selective serotonin reuptake inhibitors (SSRIs) are the main class of agents used to treat anxiety disorders. However, the impact of SSRIs on the developing brain during adolescence remains unknown. The authors assessed the impact of developmentally timed SSRI administration in a genetic mouse model displaying elevated anxiety-like behaviors. METHOD: Knock-in mice containing a common human single-nucleotide polymorphism (Val66Met; rs6265) in brain-derived neurotrophic factor (BDNF), a growth factor implicated in the mechanism of action of SSRIs, were studied based on their established phenotype of increased anxiety-like behavior...
