OBJECTIVE: Family caregivers of people with dementia often report high levels of stress and depression, but little is known about those who contemplate suicide or self-harm. This study explores thoughts of suicide, self-harm and death in dementia caregivers and investigates the characteristics that distinguish them from those without such thoughts. METHODS: Data were collected every 3 months, for 24 months, from 192 family caregivers of people with dementia living in the Netherlands...

Mindfulness is an increasingly popular therapeutic approach. Mindfulness-based interventions have been tried out in a wide range of mental disorders, with the strongest evidence for use in depression and anxiety. Mindfulness operates by changing the person's relationship with unhelpful thoughts and emotions. The need for home practice is both a strength and a weakness. Some find home practice too demanding and a barrier to effective utilisation of mindfulness. Others discover a set of practical tools that, once learnt, can be applied to ongoing life difficulties; in this way mindfulness may have a place in promoting recovery beyond the acute treatment of a disorder...

PURPOSE: To investigate predictors of conduct problem (CP) treatment in an outpatient child psychiatry clinic. DESIGN AND METHODS: Medical records (N = 78) of youth with CPs (71% male; mean age = 9.9 years) were analyzed to determine how treatment history, race, gender, travel distance, aggression symptoms, internalizing disorder symptoms, and age of diagnosis influenced initial treatment decisions. FINDINGS: Severity of aggression symptoms and travel distance significantly increased the likelihood that initial treatments included psychotropic medication...

Despite being the object of a thriving field of clinical research, the investigation of intrinsic brain network alterations in psychiatric illnesses is still in its early days. Because the pathological alterations are predominantly probed using functional magnetic resonance imaging (fMRI), many questions about the electrophysiological bases of resting-state alterations in psychiatric disorders, particularly among mood disorder patients, remain unanswered. Alongside important research using electroencephalography (EEG), the specific recent contributions and future promise of magnetoencephalography (MEG) in this field are not fully recognized and valued...

BACKGROUND: The lipidome is rapidly garnering interest in the field of psychiatry. Recent studies have implicated lipidomic changes across numerous psychiatric disorders. In particular, there is growing evidence that the concentrations of several classes of lipids are altered in those diagnosed with MDD. However, for lipidomic abnormalities to be considered potential treatment targets for MDD (rather than secondary manifestations of the disease), a shared etiology between lipid concentrations and MDD should be demonstrated...

Psychiatry and neuroscience research need novel approaches to indirectly investigate brain function. As the retina is an anatomical and developmental extension of the central nervous system (CNS), changes in retinal function may reflect neurological dysfunctions in psychiatric disorders. The last and most integrated retinal relay before visual information transfer to the brain is the ganglion cell layer. Here, based on collected arguments, we argue that these cells offer a crucial site for indirectly investigating brain function...

Children who have suffered early abuse or neglect may later present with significant health and behavior problems that may persist long after the abusive or neglectful environment has been remediated. Neurobiological research suggests that early maltreatment may result in an altered psychological and physiologic response to stressful stimuli, a response that deleteriously affects the child's subsequent development. Pediatricians can assist caregivers by helping them recognize the abused or neglected child's emotional and behavioral responses associated with child maltreatment and guide them in the use of positive parenting strategies, referring the children and families to evidence-based therapeutic treatment and mobilizing available community resources...

ZNF804A (zinc-finger protein 804A) has been recognized as a schizophrenia risk gene across multiple world populations. Its intronic single-nucleotide polymorphism (SNP) rs1344706 is among one of the strongest susceptibility variants that have achieved genome-wide significance in genome-wide association studies (GWAS) for schizophrenia and has been widely and intensively studied. To elucidate the biological mechanisms underlying the genetic risk conferred by rs1344706, we retrospectively analyzed the progresses in brain gene expression quantitative trait loci (eQTL) analyses, ZNF804A-induced pathway alterations in neural cells and changes in synaptic phenotypes associated with ZNF804A expression...

The western diet is known to have detrimental effects on cognition and the gut microbiota, but few studies have investigated how these may be related. Here, we examined whether a probiotic could prevent diet-induced memory deficits. Rats were pre-exposed to vehicle, low or high doses of VSL#3 for 2 weeks before half were switched from chow to a cafeteria diet (Caf) for 25 days; VSL#3 treatment continued until death. High-dose VSL#3 prevented the diet-induced memory deficits on the hippocampal-dependent place task, but the probiotic caused deficits on the perirhinal-dependent object task, irrespective of diet or dose...

Imaging genetics and genomics research has begun to provide insight into the molecular and genetic architecture of neural phenotypes and the neural mechanisms through which genetic risk for psychopathology may emerge. As it approaches its third decade, imaging genetics is confronted by many challenges, including the proliferation of studies using small sample sizes and diverse designs, limited replication, problems with harmonization of neural phenotypes for meta-analysis, unclear mechanisms, and evidence that effect sizes may be more modest than originally posited, with increasing evidence of polygenicity...

Mounting evidence indicates that Wnt signaling is relevant to pathophysiology of diverse mental illnesses including schizophrenia, bipolar disorder, and autism spectrum disorder. In the 35 years since Wnt ligands were first described, animal studies have richly explored how downstream Wnt signaling pathways affect an array of neurodevelopmental processes and how their disruption can lead to both neurological and behavioral phenotypes. Recently, human induced pluripotent stem cell (hiPSC) models have begun to contribute to this literature while pushing it in increasingly translational directions...

This study assessed brain structural and functional alterations in patients with Parkinson's disease and impulsive-compulsive behaviours (PD-ICB) compared with controls and PD no-ICB cases. Eighty-five PD patients (35 PD-ICB) and 50 controls were recruited. All subjects underwent three-dimensional T1-weighted, diffusion tensor (DT), and resting state functional magnetic resonance imaging (RS fMRI). We assessed cortical thickness with surface-based morphometry, subcortical volumes using FIRST, DT MRI metrics using region of interest and tractography approaches, and RS fMRI using a model free approach...

This article recounts the case of a patient with schizophrenia engaged in time-limited psychodynamic psychotherapy with a psychiatry resident-the first case history of its type to the author's knowledge. This patient suffered from chronically debilitating schizophrenia with persistent positive and negative symptoms at the time of treatment, despite usual psychiatric management. He benefited significantly from 18 weekly sessions of weekly dynamic therapy, achieving symptom reduction, increased social involvement, and improved functioning-gains that were sustained at 9-month follow-up...

Many cigarette smokers express a desire to quit smoking, but ~85% of cessation attempts fail. In our attempt to delineate genetic modulators of smoking persistence, we have earlier shown that a locus within an ~250 kb haplotype block spanning the 5' untranslated region region of insulin-degrading enzyme is associated with serum cotinine levels; the study's measure of smoking quantity. Based on our findings, and coupled with recent preclinical studies showing the importance of multiple neuropeptides in reinstatement of drug use, we formulated intranasal insulin to evaluate its efficacy during acute abstinence from smoking...

Felice N Jacka
The nascent field of 'Nutritional Psychiatry' offers much promise for addressing the large disease burden associated with mental disorders. A consistent evidence base from the observational literature confirms that the quality of individuals' diets is related to their risk for common mental disorders, such as depression. This is the case across countries and age groups. Moreover, new intervention studies implementing dietary changes suggest promise for the prevention and treatment of depression. Concurrently, data point to the utility of selected nutraceuticals as adjunctive treatments for mental disorders and as monotherapies for conditions such as ADHD...

OBJECTIVES: The first objective of this article is to summarize the history of electroconvulsive therapy (ECT) in psychiatry in order to highlight the transition from clinical level of evidence based on phenomenological descriptions to controlled trial establishing causal relationship. The second objective is to apply the criteria of causation for ECT, to focus on the dose-effect relationship criteria, and thus to analyze the conditions of application of these criteria for ECT. METHODS: A literature review exploring the use of electricity, ECT and electroencephalography (EEG) in psychiatry was conducted...
