The impact of visual dysfunctions in recent-onset psychosis and clinical high-risk state for psychosis

Subtle subjective visual dysfunctions (VisDys) are reported by about 50% of patients with schizophrenia and are suggested to predict psychosis states. Deeper insight into VisDys, particularly in early psychosis states, could foster the understanding of basic disease mechanisms mediating susceptibility to psychosis, and thereby inform preventive interventions. We systematically investigated the relationship between VisDys and core clinical measures across three early phase psychiatric conditions. Second, we used a novel multivariate pattern analysis approach to predict VisDys by resting-state functional connectivity within relevant brain systems. VisDys assessed with the Schizophrenia Proneness Instrument (SPI-A), clinical measures, and resting-state fMRI data were examined in recent-onset psychosis (ROP, n = 147), clinical high-risk states of psychosis (CHR, n = 143), recent-onset depression (ROD, n = 151), and healthy controls (HC, n = 280). Our multivariate pattern analysis approach used pairwise functional connectivity within occipital (ON) and frontoparietal (FPN) networks implicated in visual information processing to predict VisDys. VisDys were reported more often in ROP (50.34%), and CHR (55.94%) than in ROD (16.56%), and HC (4.28%). Higher severity of VisDys was associated with less functional remission in both CHR and ROP, and, in CHR specifically, lower quality of life (Qol), higher depressiveness, and more severe impairment of visuospatial constructability. ON functional connectivity predicted presence of VisDys in ROP (balanced accuracy 60.17%, p = 0.0001) and CHR (67.38%, p = 0.029), while in the combined ROP + CHR sample VisDys were predicted by FPN (61.11%, p = 0.006). These large-sample study findings suggest that VisDys are clinically highly relevant not only in ROP but especially in CHR, being closely related to aspects of functional outcome, depressiveness, and Qol. Findings from multivariate pattern analysis support a model of functional integrity within ON and FPN driving the VisDys phenomenon and being implicated in core disease mechanisms of early psychosis states

Transdiagnostic subgroups of cognitive impairment in early affective and psychotic illness

Abstract: Cognitively impaired and spared patient subgroups were identified in psychosis and depression, and in clinical high-risk for psychosis (CHR). Studies suggest differences in underlying brain structural and functional characteristics. It is unclear whether cognitive subgroups are transdiagnostic phenomena in early stages of psychotic and affective disorder which can be validated on the neural level. Patients with recent-onset psychosis (ROP; N = 140; female = 54), recent-onset depression (ROD; N = 130; female = 73), CHR (N = 128; female = 61) and healthy controls (HC; N = 270; female = 165) were recruited through the multi-site study PRONIA. The transdiagnostic sample and individual study groups were clustered into subgroups based on their performance in eight cognitive domains and characterized by gray matter volume (sMRI) and resting-state functional connectivity (rsFC) using support vector machine (SVM) classification. We identified an impaired subgroup (N ROP = 79, N ROD = 30, N CHR = 37) showing cognitive impairment in executive functioning, working memory, processing speed and verbal learning (all p < 0.001). A spared subgroup (N ROP = 61, N ROD = 100, N CHR = 91) performed comparable to HC. Single-disease subgroups indicated that cognitive impairment is stronger pronounced in impaired ROP compared to impaired ROD and CHR. Subgroups in ROP and ROD showed specific symptom- and functioning-patterns. rsFC showed superior accuracy compared to sMRI in differentiating transdiagnostic subgroups from HC (BACimpaired = 58.5%; BACspared = 61.7%, both: p < 0.01). Cognitive findings were validated in the PRONIA replication sample (N = 409). Individual cognitive subgroups in ROP, ROD and CHR are more informative than transdiagnostic subgroups as they map onto individual cognitive impairment and specific functioning- and symptom-patterns which show limited overlap in sMRI and rsFC.

Association between age of cannabis initiation and gray matter covariance networks in recent onset psychosis

Cannabis use during adolescence is associated with an increased risk of developing psychosis. According to a current hypothesis, this results from detrimental effects of early cannabis use on brain maturation during this vulnerable period. However, studies investigating the interaction between early cannabis use and brain structural alterations hitherto reported inconclusive findings. We investigated effects of age of cannabis initiation on psychosis using data from the multicentric Personalized Prognostic Tools for Early Psychosis Management (PRONIA) and the Cannabis Induced Psychosis (CIP) studies, yielding a total sample of 102 clinically-relevant cannabis users with recent onset psychosis. GM covariance underlies shared maturational processes. Therefore, we performed source-based morphometry analysis with spatial constraints on structural brain networks showing significant alterations in schizophrenia in a previous multisite study, thus testing associations of these networks with the age of cannabis initiation and with confounding factors. Earlier cannabis initiation was associated with more severe positive symptoms in our cohort. Greater gray matter volume (GMV) in the previously identified cerebellar schizophrenia-related network had a significant association with early cannabis use, independent of several possibly confounding factors. Moreover, GMV in the cerebellar network was associated with lower volume in another network previously associated with schizophrenia, comprising the insula, superior temporal, and inferior frontal gyrus. These findings are in line with previous investigations in healthy cannabis users, and suggest that early initiation of cannabis perturbs the developmental trajectory of certain structural brain networks in a manner imparting risk for psychosis later in life

‘There's more to a person than what's in front of you’: nursing students’ experiences of consumer taught mental health education

Holistic and person-centred nursing care is commonly regarded as fundamental to nursing practice. These approaches are complementary to recovery which is rapidly becoming the preferred mode of practice within mental health. The willingness and ability of nurses to adopt recovery-oriented practice is essential to services realizing recovery goals. Involving consumers (referred herein as Experts by Experience) in mental health nursing education has demonstrated positive impact on the skills and attitudes of nursing students. A qualitative exploratory research project was undertaken to examine the perspectives of undergraduate nursing students to Expert by Experience-led teaching as part of a co-produced learning module developed through an international study. Focus groups were held with students at each site. Data were analysed thematically. Understanding the person behind the diagnosis was a major theme, including subthemes: person-centred care/seeing the whole person; getting to know the person, understanding, listening; and challenging the medical model, embracing recovery. Participants described recognizing consumers as far more than their psychiatric diagnoses, and the importance of person-centred care and recovery-oriented practice. Understanding the individuality of consumers, their needs and goals, is crucial in mental health and all areas of nursing practice. These findings suggest that recovery, taught by Experts by Experience, is effective and impactful on students' approach to practice. Further research addressing the impact of Experts by Experience is crucial to enhance our understanding of ways to facilitate the development of recovery-oriented practice in mental health and holistic and person-centred practice in all areas of health care.Brenda Happell, Shifra Waks, Julia Bocking, Aine Horgan, Fionnuala Manning ...

Something special, something unique: Perspectives of experts by experience in mental health nursing education on their contribution

WHAT IS KNOWN ON THE SUBJECT: ●Expert by Experience participation in mental health services is embedded in mental health policy in many countries. The negative attitudes of nurses and other health professionals to consumer participation poses a significant obstacle to this policy goal. ●Involving mental health Experts by Experience in the education of nursing students demonstrates positive attitudinal change. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: ●The paper presents perspectives from Experts by Experience about the unique knowledge and expertise they derive from their lived experience of mental distress and mental health service use. As a result, they can make a unique and essential contribution to mental health nursing education. They utilize this knowledge to create an interactive learning environment and encourage critical thinking. ●The international focus of this research enriches understandings about how Experts by Experience might be perceived in a broader range of countries. WHAT ARE THE IMPLICATIONS FOR PRACTICE: ●Mental health policy articulates the importance of service user involvement in all aspects of mental health service delivery. This goal will not be fully achieved without nurses having positive attitudes towards experts by experience as colleagues. ●Positive attitudes are more likely to develop when nurses understand and value the contribution experts by experience bring by virtue of their unique knowledge and expertise. This paper provides some important insights to achieving this end. ABSTRACT: Introduction Embedding lived experience in mental health nursing education is increasing, with research findings suggesting the impact is positive. To date, research has primarily targeted the perspectives of nursing students and academics from the health professions. Aim To enhance understanding of the unique knowledge and expertise experts by experience contribute to mental health nursing education. Methods Qualitative exploratory research methods were employed. In-depth individual interviews were conducted with experts by experience who delivered a coproduced learning module to nursing students in Europe and Australia. Results Participants described their unique and essential contribution to mental health nursing education under four main themes: critical thinking, beyond textbooks; interactive and open communication; understanding personal recovery; and mental health is health. Conclusions These findings present an understanding of the unique knowledge and expertise Experts by Experience contribute to mental health education not previously addressed in the literature. Appreciating and respecting this, unique contribute is necessary as Expert by Experience contributions continue to develop. Implications for Practice Mental health services purport to value service user involvement. Identifying and respecting and valuing the unique contribution they bring to services is essential. Without this understanding, tokenistic involvement may become a major barrier
