UNASSIGNED: Schizophrenia is associated with white matter disruption and topological reorganization of cortical connectivity but the trajectory of these changes, from the first psychotic episode to established illness, is poorly understood. Current studies in first-episode psychosis (FEP) patients using diffusion magnetic resonance imaging (dMRI) suggest such disruption may be detectable at the onset of psychosis, but specific results vary widely, and few reports have contextualized their findings with direct comparison to young adults with established illness.
UNASSIGNED: Diffusion and T1-weighted 7T MR scans were obtained from N = 112 individuals (58 with untreated FEP, 17 with established schizophrenia, 37 healthy controls) recruited from London, Ontario. Voxel- and network-based analyses were used to detect changes in diffusion microstructural parameters. Graph theory metrics were used to probe changes in the cortical network hierarchy and to assess the vulnerability of hub regions to disruption. The analysis was replicated with N = 111 (57 patients, 54 controls) from the Human Connectome Project-Early Psychosis (HCP-EP) dataset.
UNASSIGNED: Widespread microstructural changes were found in people with established illness, but changes in FEP patients were minimal. Unlike the established illness group, no appreciable topological changes in the cortical network were observed in FEP patients. These results were replicated in the early psychosis patients of the HCP-EP datasets, which were indistinguishable from controls in most metrics.
UNASSIGNED: The white matter structural changes observed in established schizophrenia are not a prominent feature in the early stages of this illness.

UNASSIGNED: Research has established a relationship between psychosis and physical harm in the early course of psychosis. However, little is known about the relationship between specific psychosis symptoms, such as hearing voices, and physical harm.
UNASSIGNED: This study aimed to determine the prevalence and typology of physical harm related to hearing voices, as well as what aspects of the voice-hearing experience retrospectively predicted incidents of harm within an Early Intervention in Psychosis Service (EIPS).
UNASSIGNED: We conducted a quality improvement project in a single EIPS. We reviewed case notes of patients and extracted information on the cognitive-phenomenological features of the voices patients heard, as well as any incidents of physical harm that were causally linked to these voices.
UNASSIGNED: It was found that 32.2% of EI patients had an actual incident of physical harm in their case notes that was causally linked to hearing voices. The most common type of physical harm was neglect. In terms of cognitive phenomenological binary correlations that retrospectively predicted physical harm in the case notes, patients were 20 and 7 times more likely to have harmed themselves if they heard self-harm commands (i.e., directions to harm themselves physically) and perceived the voice as omnipotent, respectively. Patients were 6 times more likely to have harmed someone else if they heard violent commands.
UNASSIGNED: Verbal auditory hallucinations commonly influence physical harm in the early course of psychosis. Hearing commands and/or believing the voice to be omnipotent are strong retrospective-correlative predictors that may aid in the assessment and therapeutic intervention.

OBJECTIVE: Despite the high rates of psychotic disorders amongst people in prison, current prison mental health screening approaches have not included assessment of the full psychosis spectrum to capture those at-risk of an emerging psychosis as well as those with established illness nor assessed the concurrent validity of psychosis symptom screening.
METHODS: Using a clinical staging approach to establish the prevalence of Ultra High Risk (UHR), first episode of psychosis (FEP) and established psychosis (EP) groups, 291 adults entering custody in two prison reception centres in NSW completed a two-stage (screening and validation) interview process. The Comprehensive Assessment of At-Risk Mental States (CAARMS) was used to determine the clinical stages of psychosis and concurrent validity of symptom screening in identifying individuals on the psychosis spectrum was formally assessed.
RESULTS: Amongst men and women entering prison, almost one quarter (24.1%) met UHR criteria, 5.1% met the FEP threshold and 10.6% had an established psychosis. Those on the psychosis spectrum reported greater disadvantage across sociodemographic and justice factors. The presence of perceptual disturbance and paranoid beliefs emerged as the two best screening items for identifying those with an underlying psychosis spectrum illness.
CONCLUSIONS: The prevalence of psychosis spectrum illness, including the UHR state, amongst those entering prison is high. Current prison mental health approaches should include screening for the presence of perceptual disturbances and paranoid beliefs to improve the detection of psychosis spectrum illness.

BACKGROUND: Individuals at Clinical High Risk (CHR) for psychosis or in their First Episode (FE) of psychosis are in a pivotal time in adolescence or young adulthood when illness can greatly impact their functioning. Finding relevant biomarkers for psychosis in the early stages of illness can contribute to early diagnosis, therapeutic management and prediction of outcome. One such biomarker that has been studied in schizophrenia (SZ) is visual contrast sensitivity (VCS). VCS can be used to differentiate visual information processing function in the magnocellular versus parvocellular visual pathways. Few studies have assessed VCS in early psychosis.
METHODS: Participants included CHR (n = 68), FE psychosis (n = 34) and Healthy Comparison (HC) (n = 63). All were clinically assessed and completed a VCS paradigm that involved near threshold luminance and chromatic stimuli.
RESULTS: CHR and FE participants had lower VCS in the luminance condition (F[2166] = 3.42, p < 0.05) compared to HC. There was also a significant sex X group interaction (F[5163] = 4.3, p < 0.001) in the luminance condition (F[5163] = 4.3, p < 0.001) as FE males (p < 0.01) and CHR females (p < 0.01) had the greatest deficits compared to male and female HC participants respectively. VCS deficits in the luminance condition were associated with more thought disorder, slower processing speed, worse executive functioning and poor global functioning (r\'s 0.25-0.50, p < 0.05).
CONCLUSIONS: This study supports the hypothesis that there are deficits in visual information processing, particularly in tasks that emphasize the magnocellular pathway, in patients experiencing early psychosis. VCS therefore has the potential to be used as a biomarker in this population.

Tobacco smoking is highly prevalent among patients with psychosis and associated with worse clinical outcomes. Neurometabolites, such as glutamate and choline, are both implicated in psychosis and tobacco smoking. However, the specific associations between smoking and neurometabolites have yet to be investigated in patients with psychosis. The current study examines associations of chronic smoking and neurometabolite levels in the anterior cingulate cortex (ACC) in first-episode psychosis (FEP) patients and controls. Proton magnetic resonance spectroscopy (1H MRS) data of 59 FEP patients and 35 controls were analysed. Associations between smoking status (i.e., smoker yes/no) or cigarettes per day and Glx (glutamate + glutamine, as proxy for glutamate) and total choline (tCh) levels were assessed at baseline in both groups separately. For patients, six months follow-up data were acquired for multi-cross-sectional analysis using linear mixed models. No significant differences in ACC Glx levels were found between smoking (n = 28) and non-smoking (n = 31) FEP patients. Smoking patients showed lower tCh levels compared to non-smoking patients at baseline, although not surving multiple comparisons correction, and in multi-cross-sectional analysis (pFDR = 0.08 and pFDR = 0.044, respectively). Negative associations were observed between cigarettes smoked per day, and ACC Glx (pFDR = 0.02) and tCh levels (pFDR = 0.02) in controls. Differences between patients and controls regarding Glx might be explained by pre-existing disease-related glutamate deficits or alterations at nicotine acetylcholine receptor level, resulting in differences in tobacco-related associations with neurometabolites. Additionally, observed alterations in tCh levels, suggesting reduced cellular proliferation processes, might result from exposure to the neurotoxic effects of smoking.

BACKGROUND: Self-stigma remains one of the most vexing issues in psychiatry. It complicates the treatment and social functioning of patients with endogenous psychiatric disorders. Identifying the specific features of self-stigma depending on the type and duration of the endogenous mental illness can help solve this problem.
OBJECTIVE: The aim of this study was to establish the level and specific features of self-stigma in patients with various types of chronic endogenous psychiatric disorders at different disease stages and to establish the correlation between the level of self-stigma and the attitude of the patient to his/her disease and treatment.
METHODS: Clinical psychopathology assessment, psychometric scales and questionnaires: \"Positive and Negative Syndrome Scale\" (PANSS), \"Questionnaire for Self-Stigma Assessment in Mentally Ill Patients\", and Russian versions of the \"Insight Scale for Psychosis\" (ISP), and \"Drug Attitude Inventory\" (DAI-10). The cross-sectional study included 86 patients with endogenous mental illnesses (bipolar affective disorder and schizophrenia spectrum disorders.
RESULTS: The analysis of the results of the \"Questionnaire for Self-Stigma Assessment in Mentally Ill Patients\" showed that at the initial disease stages the highest level of self-stigma is observed in patients with bipolar affective disorder (M±σ=1.22±0.73; Me [Q1; Q3]=1.10 [0.83; 1.60]), while the lowest level was observed in patients with schizophrenia spectrum disorders (M±σ=0.86±0.53; Me [Q1; Q3]=0.77 [0.31; 1.25]). Patients with schizophrenia and schizoaffective disorder and a disease duration more than five years participating in a long-term comprehensive psychosocial rehabilitation program also demonstrated high rates of self-stigma (M±σ=1.20±0.57, Me [Q1; Q3]=1.26 [0.89; 1.47]). The study groups showed differences in terms of the structure of components of self-stigma and their severity; significant correlations were uncovered between the self-stigma parameters and the attitude of patients to their disease and therapy.
CONCLUSIONS: The results of this study contribute to a better understanding of the specific features of self-stigma in patients with various endogenous disorders at different stages of the disease. These data can be used as part of a comprehensive psychosocial treatment program for this patient cohort, as well as for future research.
UNASSIGNED: Самостигматизация остается одной из актуальных проблем современной психиатрии, которая затрудняет лечение и социальное функционирование пациентов с эндогенными психическими расстройствами. Решению этой проблемы может способствовать определение особенностей и специфики самостигматизации в зависимости от формы и длительности эндогенного психического расстройства.
UNASSIGNED: Установить уровень и особенности самостигматизации у пациентов с различными формами эндогенных хронических психических расстройств на разных этапах болезни и выявить связь выраженности самостигматизации с отношением к своему заболеванию и лечению.
UNASSIGNED: Клинико - психопатологический, психометрические шкалы и опросники (« Опросник для оценки феномена самостигматизации психически больных », « Шкала позитивных и негативных симптомов — «Positive and Negative Syndrome Scale» (PANSS), русскоязычные версии опросников « Осознание болезни » — «Insight Scale for Psychosis» (ISP), « Отношение к лекарственным препаратам » — «Drug attitude inventory» (DAI-10). Проведено кроссекционное исследование 86 пациентов с эндогенными психическими заболеваниями (биполярное аффективное расстройство и расстройства шизофренического спектра).
UNASSIGNED: С помощью « Опросника для оценки феномена самостигматизации психически больных » установлено, что на начальном этапе заболевания наибольший уровень самостигматизации характерен для пациентов с биполярным аффективным расстройством (M±σ=1,22±0,73; Me [Q1; Q3]=1,10 [0,83; 1,60]), наиболее низкий выявлен у пациентов с расстройствами шизофренического спектра (M±σ=0,86±0,53; Me [Q1; Q3]= 0,77 [0,31; 1,25]). Пациенты с шизофренией и шизоаффективным расстройством и длительностью заболевания более 5 лет, участвующие в долгосрочной комплексной программе психосоциальной реабилитации, также продемонстрировали высокие показатели самостигматизации (M±σ=1,20±0,57, Me [Q1; Q3]= 1,26 [0,89; 1,47]). В изученных группах обнаружены различия в структуре компонентов самостигматизации пациентов и их выраженности и получены достоверные корреляционные связи между показателями самостигматизации, отношением пациентов к имеющемуся психическому расстройству и получаемому лечению.
UNASSIGNED: Результаты проведенного исследования уточняют и расширяют имеющиеся знания об особенностях самостигматизации у пациентов с различными эндогенными расстройствами на разных этапах заболевания. Полученные данные могут послужить основой для дальнейших исследований, а также для использования в комплексном психосоциальном лечении таких пациентов.

In this paper, we explore the rationale for a combined art therapy and mentalization-based treatment (MBT) group course for those experiencing a first episode of psychosis (FEP). We discuss the theoretical background for how art and MBT theory can help us better understand and work with groups of individuals experiencing FEP, particularly focusing on avoidance and insecure attachment styles. We outline the delivery of a ten-week psychoeducational Art MBT course within an Early Intervention in Psychosis (EIP) Service and discuss our experiential insights into this new modality as co-therapists. We conclude by proposing that art therapy and mentalizing practice together offer an accessible, useful and practical group structure for EIP services, which could improve individuals\' mentalizing capacity and overall social functioning.

BACKGROUND: A previous meta-analysis indicated stable progress in cognitive functions in early psychosis, assessed through various tools. To avoid assessment-related heterogeneity, this study aims to examine the longitudinal cognitive function changes in early psychosis utilizing the MATRICS Consensus Cognitive Battery (MCCB).
METHODS: Embase, PubMed, and Scopus were systematically searched from their inception to September 26th 2023. The inclusion criteria were longitudinal studies that presented follow-up MCCB data for individuals experiencing first-episode psychosis (FEP) and those with ultra-high risk for psychosis (UHR).
RESULTS: Twelve studies with 791 participants (566 FEP patients and 225 healthy controls) were subjected to analysis. Suitable UHR studies were absent. Over time, both FEP patients and healthy controls showed significant improvements in MCCB total scores. Furthermore, FEP patients demonstrated improvements across all MCCB domains, while healthy controls only showed augmentations in specific domains such as speed of processing, attention, working memory, and reasoning and problem-solving. Visuospatial learning improvements were significantly greater in FEP patients compared to healthy controls. Subgroup analyses suggested that neither diagnostic type nor follow-up duration influenced the magnitude of cognitive improvement in FEP patients.
CONCLUSIONS: The magnitude of cognitive improvement for MCCB domains was not significantly different between FEP and healthy controls other than visuospatial learning. This underscores visuospatial learning as a potentially sensitive cognitive marker for early pathologic state changes in psychotic disorders.

BACKGROUND: Suicidal ideation is common among individuals with first episode psychosis (FEP), with prevalence estimates up to 56.5 %. Despite its high prevalence, relatively little is known about how sociodemographic, clinical and/or developmental characteristics contribute to the experience of suicidal ideation in individuals with FEP.
METHODS: In this cross-sectional study (FEP n = 551 and controls n = 857), univariate logistic regression analyses were performed to study the associations of sociodemographic, clinical, and developmental factors with suicidal ideation in individuals with FEP as well as controls. Suicidal ideation was assessed using the Community Assessment of Psychic Experiences (CAPE). In addition, multivariate logistic regression analyses were conducted based on a stepwise approach.
RESULTS: In FEP, only depressive symptoms remained significantly associated with suicidal ideation when all correlates were integrated into one model. In the multivariate model in controls, depressive symptoms, positive symptoms, and traumatic childhood experiences were significantly associated with suicidal ideation.
CONCLUSIONS: This study showed that depressive symptoms are an important factor relating to suicidal ideation in individuals with FEP, over and above other clinical, sociodemographic, and developmental factors. This underscores the relevance of screening for suicidal ideation in individuals with FEP, and highlights the need for a better understanding of the diagnostic uncertainty and course of mood symptoms in early psychosis.
CONCLUSIONS: Cross-sectional study design, self-reported questionnaires.

OBJECTIVE: Diagnostic stability for people with First Episode Psychosis (FEP) is essential for treatment, but it remains poorly investigated, especially in adolescents and within a prospective design. The aims of this research were: (a) to examine diagnostic change in Italian adolescents with FEP treated within an \"Early Intervention in Psychosis\" program during a 2-year follow-up period and (b) to investigate any sociodemographic and clinical predictors at baseline.
METHODS: At baseline, 66 adolescents with FEP was recruited. Their primary diagnosis was formulated both at baseline and at the end of follow-up. At presentation, FEP adolescents completed the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA). As for diagnostic stability, the Kappa statistic was calculated. The associations of diagnostic change with baseline clinical and sociodemographic features were analyzed using a logistic model with the diagnostic shift as dependent variable. A propensity score was finally calculated based on logistic analysis results.
RESULTS: 38 (57.6%) FEP adolescents changed their opening diagnosis. The highest prospective diagnostic stability was for initial diagnosis of schizophrenia (95.4%) and affective spectrum psychoses (75%). Diagnostic instability was high for opening diagnosis of psychosis not otherwise specified, brief psychosis and schizophreniform disorder (100%). The best predictors of diagnostic change were fewer years of education, shorter duration of untreated psychosis and higher baseline levels of psychiatric symptoms.
CONCLUSIONS: Diagnostic stability is crucial for treatment and clinical decision making. Addressing instability in FEP diagnoses is an important challenge for future diagnostic development in early psychosis, especially in adolescence.
