Introduction: Since only around 10% of people with gambling disorder (GD) seek professional treatment or attend self-help groups, multiple strategies are needed to improve this rate. The proposal of the Behavioral Addictions Centre 'Adcom' (Madrid, Spain) is one of these strategies, a pioneering and innovative program aimed at the general population to identify people with addictions such as GD, in an attempt tp offer them appropriate evidence-based treatments.

Materials And Methods: We analyzed information obtained from the first 305 adults who voluntarily sought attention at Adcom for self-referred gambling, and conducted a descriptive, cross-sectional and observational study of this population.

Objective: Insomnia Disorder is a chronic mental disorder with significant impact on the population across Europe and Canada. While some countries reimburse evidence-based treatments, others fail to recognize insomnia as a chronic condition and do not provide the resources to ensure consistent care for those affected. This document serves as a position paper from sleep and mental health experts across Europe, Switzerland the UK, and Canada, emphasizing the critical need for public health systems to recognize chronic insomnia as a disorder in order to enhance support for patients.

The presence of autoantibodies against myelin oligodendrocyte glycoprotein (MOG) is a hallmark of MOG antibody-associated disease (MOGAD), a recently defined demyelinating disease entity presenting with core clinical features of optic neuritis, myelitis, and acute disseminated encephalomyelitis. Although MOG antibodies have also been described in a small number of patients with other conditions, including mental disorders, their prevalence and clinical specificity in patients with isolated psychotic symptoms remain unclear. Here, we screened sera from 262 patients with at least one psychotic episode and 166 control subjects for the presence of MOG antibodies of the immunoglobulin G (IgG) isotype with a live cell-based assay.

Imaging transcriptomics has become a power tool for linking imaging-derived phenotypes (IDPs) to genomic mechanisms. Yet, its potential for guiding CNS drug discovery remains underexplored. Here, utilizing spatially-dense representations of the human brain transcriptome, we present an analytical framework for the transcriptomic decoding of high-resolution surface-based neuroimaging patterns, and for linking IDPs to the transcriptomic landscape of complex neurotransmission systems in vivo.

Background: The macro-social and environmental conditions in which people live, such as the level of a country's development or inequality, are associated with brain-related disorders. However, the relationship between these systemic environmental factors and the brain remains unclear. We aimed to determine the association between the level of development and inequality of a country and the brain structure of healthy adults.

Extrapyramidal symptoms (EPS) may occur as a primary feature in patients with first-episode psychosis with no or brief exposure to antipsychotics (AP). We aimed to analyse the prevalence of EPS in naïve and quasi-naïve first episode schizophrenia spectrum disorders (FES), their demographic and clinical correlates at baseline, and their association with clinical outcomes during follow-up. We analysed data from the OPTiMiSE trial, Phase 1 (n = 481 participants with FES, aged 18-40).

Background: Prolonged childhood and adolescent loneliness (CAL) is linked to various adverse mental health outcomes, yet its impact on schizophrenia spectrum disorders (SSD) has been understudied. While loneliness is associated with psychosis and worsens symptoms in SSD, few studies have explored the long-term effects of early loneliness on SSD risk. Understanding how CAL interacts with genetic liability to schizophrenia is essential for identification of high-risk individuals.

Individuals at clinical high risk for psychosis (CHR) have variable clinical outcomes and low conversion rates, limiting development of novel and personalized treatments. Moreover, given risks of antipsychotic drugs, safer effective medications for CHR individuals are needed. The Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ) Program was launched to address this need.

Although meta-analytic studies have shown that 25-33% of those at Clinical High Risk (CHR) for psychosis transition to a first episode of psychosis within three years, less is known about estimating the risk of transition at an individual level. Digital phenotyping offers a novel approach to explore the nature of CHR and may help to improve personalized risk prediction. Specifically, digital data enable detailed mapping of experiences, moods and behaviors during longer periods of time (e.

Major depressive disorder (MDD) represents a major global health challenge, with a significant proportion of patients being resistant to drug treatment (TRD). Repetitive transcranial magnetic stimulation (rTMS) has shown promise in the treatment of MDD/TRD, with a single stimulation session per day for five days per week over several weeks (the "standard" protocol). The two main paradigms used are high-frequency rTMS and intermittent theta burst stimulation (iTBS) delivered to the left dorsolateral prefrontal cortex (DLPFC).

Background: Treatment of schizophrenia has traditionally aimed for symptomatic remission without addressing many daily problems patients face. Although no standard definition of functional recovery in patients with first-episode psychosis (FEP) and early-phase (EP) schizophrenia exists in the literature, most clinicians consider it a useful concept in daily practice. We conducted a Delphi panel to develop expert consensus on assessing functional recovery in FEP and EP schizophrenia patients and defining its domains, which we compared with currently available patient- and clinician-reported outcome measures (PROMs, CROMs).

First episode psychosis (FEP) individuals show biological abnormalities preceding antipsychotic treatment. However, it remains unclear whether such alterations are also present before the onset of psychosis. We aim to provide estimates of standardized mean differences for immune, cardiometabolic, prolactin, and HPA axis parameters in individuals at clinical high-risk for psychosis (CHR-P) compared to healthy controls (HC) and FEP individuals, and between CHR-P transitioning to psychosis (CHR-T) compared non-transitioning (CHR-NT).
