<b><i>Introduction:</i></b> Increased efforts in neuroscience try to understand mental disorders as brain disorders. In the present study, we investigate how common a neuroreductionist inclination is among highly educated people. In particular, we shed light on implicit presuppositions of mental disorders little is known about in the public, exemplified here by the case of body integrity dysphoria (BID) that is considered a mental disorder for the first time in ICD-11. <b><i>Methods:</i></b> Identically graphed, simulated data of mind-brain correlations were shown in 3 contexts with presumably different presumptions about causality. 738 highly educated lay people rated plausibility of causality attribution from the brain to mind and from mind to the brain for correlations between brain structural properties and mental phenomena. We contrasted participants’ plausibility ratings of causality in the contexts of commonly perceived brain lesion-induced behavior (aphasia), behavior-induced training effects (piano playing), and a newly described mental disorder (BID). <b><i>Results:</i></b> The findings reveal the expected context-dependent modulation of causality attributions in the contexts of aphasia and piano playing. Furthermore, we observed a significant tendency to more readily attribute causal inference from the brain to mind than vice versa with respect to BID. <b><i>Conclusion:</i></b> In some contexts, exemplified here by aphasia and piano playing, unidirectional causality attributions may be justified. However, with respect to BID, we critically discuss presumably unjustified neuroreductionist inclinations under causal uncertainty. Finally, we emphasize the need for a presupposition-free approach in psychiatry.

The basic claims of the chapter are, first, that mental disorders are not best understood as types of brain disorder, even though mental disorders are based in the brain. And, second, that the difference between the two sorts of disorders can be illuminated by the sorts of treatment or therapy that may work for the one type (a mental disorder) but not for the other type (a brain disorder). In the discussion some of the diagnostic implications and difficulties associated with these two basic claims are outlined.

Circulatory Disturbances

When I first began the study of mental disorders, I realized that patients were, apart from their mental disorder, physically ill, and I was attracted to a study of the circulatory disturbances in these cases. This led me to consider whether these general circulatory disturbances were responsible for the mental state, in the same way that intracranial circulatory disturbances were in surgical brain cases showing mental symptoms. Examination almost invariably revealed weakness of the heart's action, irregularity of the pulse, low or high blood-pressure, and disturbances of the peripheral circulation. It was thus conceivable that disturbance of blood composition and supply might cause disturbance of oxidation in the brain and that many of these abnormal circulatory manifestations might be responsible for the production of mental disturbances. A study of various physiological and biochemical observations suggested that possibly there was in these cases some deficiency of essential salts, such as calcium. This led me to the treatment of mental disorders by the administration of salts of calcium—choosing calcium lactate. Fortunately I found at that time (1919) a very remarkable case showing severe mental symptoms and unusual circulatory disturbances.

Schizophrenia is a disease that affects the brain and causes strange and disturbed thoughts, perceptions, emotions, movements and behaviors called schizophrenia (Videbeck, 2008). Globally, the recurrence rate in people with mental disorders reaches 50% -92% due to non-compliance in treatment or due to lack of support and vulnerable living conditions with increased stress (Sheewangisaw, 2012). Clients diagnosed with schizophrenia are estimated to have a 50% relapse in the first year, 70% in the second year after discharge from hospital, and a 100% recurrence in the fifth year. . Data on patient visits at the Outpatient Polyclinic of RSJD Jambi Province in 2016 amounted to 38,330 visits, of which 35,448 visits were repeat visits and the remaining 2882 were new visits. It is hoped that the results of health education activities for patients and their families will understand the concept of nursing problems that cause mental disorder patients to recur.

BackgroundNeuroimaging techniques provide rich and accurate measures of brain structure and function, and have become one of the most popular methods in mental health and neuroscience research. Rapidly growing neuroimaging research generates massive amounts of data, bringing new challenges in data collection, large-scale data management, efficient computing requirements and data mining and analyses.AimsTo tackle the challenges and promote the application of neuroimaging technology in clinical practice, we developed an integrated neuroimaging cloud (INCloud). INCloud provides a full-stack solution for the entire process of large-scale neuroimaging data collection, management, analysis and clinical applications.MethodsINCloud consists of data acquisition systems, a data warehouse, automatic multimodal image quality check and processing systems, a brain feature library, a high-performance computing cluster and computer-aided diagnosis systems (CADS) for mental disorders. A unique design of INCloud is the brain feature library that converts the unit of data management from image to image features such as hippocampal volume. Connecting the CADS to the scientific database, INCloud allows the accumulation of scientific data to continuously improve the accuracy of objective diagnosis of mental disorders.ResultsUsers can manage and analyze neuroimaging data on INCloud, without the need to download them to the local device. INCloud users can query, manage, analyze and share image features based on customized criteria. Several examples of 'mega-analyses' based on the brain feature library are shown.ConclusionsCompared with traditional neuroimaging acquisition and analysis workflow, INCloud features safe and convenient data management and sharing, reduced technical requirements for researchers, high-efficiency computing and data mining, and straightforward translations to clinical service. The design and implementation of the system are also applicable to imaging research platforms in other fields.

AbstractNeuropsychiatry searches to understand mental disorders in terms of underlying brain activity by using brain imaging technologies. The field promises to offer a more objective foundation for diagnostic processes and to help developing forms of treatment that target the symptoms of a specific mental disorder. However, brain imaging technologies also reveal the brain as a complex network, suggesting that mental disorders cannot be easily linked to specific brain areas. In this paper, we analyze a case study conducted at a neuropsychiatry laboratory to explore how the complexity of the human brain is managed in light of the project of explaining mental disorders in terms of their neurological substrates. We use a combination of ethnomethodology and conversation analysis to show how previously assigned diagnostic labels are constitutive of interpretations of experimental data and, therefore, remain unchallenged. Furthermore, we show how diagnostic labels become materialized in experimental design, in that the linking of symptoms of mental disorders to specific brain areas is treated as indicative of successfully designed experimental stimuli. In conclusion, we argue that while researchers acknowledge the complexity of the brain on a generic level, they do not grant this complexity to the brains of individuals diagnosed with a mental disorder.

ObjectiveTo evaluate the association between having arthritis and the perceived need for mental healthcare and use of mental health support among individuals with mental disorders.DesignA cross-sectional analysis using data from Canadian Community Health Survey—Mental Health (2012).SettingThe survey was administered across Canada’s 10 provinces using multistage cluster sampling.ParticipantsThe study sample consisted of individuals reporting depression, anxiety or bipolar disorder.Study variables and analysisThe explanatory variable was self-reported doctor-diagnosed arthritis, and outcomes were perceived need for mental healthcare and use of mental health support. We computed overall and gender-stratified multivariable binomial logistic regression models adjusted for age, gender, race/ethnicity, income and geographical region.ResultsAmong 1774 individuals with a mental disorder in the study sample, 436 (20.4%) reported having arthritis. Arthritis was associated with increased odds of having a perceived need for mental healthcare (adjusted OR (aOR) 1.71, 95% CI 1.06 to 2.77). In the gender-stratified models, this association was increased among men (aOR 2.69, 95% CI 1.32 to 5.49) but not women (aOR 1.48, 95% CI 0.78 to 2.82). Evaluation of the association between arthritis and use of mental health support resulted in an aOR of 1.50 (95% CI 0.89 to 2.51). Individuals with arthritis tended to use medications and professional services as opposed to non-professional support.ConclusionComorbid arthritis among individuals with a mental disorder was associated with an increased perceived need for mental healthcare, especially in men, underscoring the importance of understanding the role of masculinity in health seeking. Assessing the mental health of patients with arthritis continues to be essential for clinical care.

Objectives: This study aimed to (1) examine the strength of the association between mental disorders/mental health problems, risk behaviours and tobacco smoking among Australian adolescents, (2) compare rates of tobacco smoking among Australian adolescents with major depressive disorder, attention-deficit/hyperactivity disorder and/or conduct disorder in 2013/14 vs 1998, and (3) identify the extent to which an association between tobacco smoking and mental health problems among adolescents can be attributed to non-mental health risk factors. Methods: The study utilised data from the first (1998) and second (2013/14) child and adolescent components of the National Surveys of Mental Health and Wellbeing. Both surveys identified nationally representative samples of Australian young people aged 4–17 years, living in private dwellings. Information was collected from parents and 13- to 17-year-olds about mental disorders, mental health problems, risk behaviours and tobacco smoking. Results: In the 2013/14 survey, the rate of current tobacco smoking among those with a mental disorder was 20% compared to 5% in those without a mental disorder. Rates were highest for young people with conduct disorder (50%), major depressive disorder (24%) and anxiety disorders (19%). In 2013/14, 38% of current tobacco smokers had a mental disorder and 32% reported self-harm and/or suicidal ideation vs 10% and 5%, respectively, among adolescents who had never smoked. Females with mental disorders or reporting self-harm or suicidal ideation had higher rates of current smoking than males. Other significant factors associated with current smoking included school-related problems, binge eating and having had more than one sexual partner. Conclusion: While smoking rates in 13- to 17-year-olds with mental disorders had declined since 1998, the strength of the association between mental disorders and smoking had increased, especially among females. Our findings highlight the need to address the tobacco smoking among adolescents with mental disorders, particularly females.

Abstract Irradiation with ultraviolet (UV) light on the cortical surface can induce a focal brain lesion (UV lesion) in rodents. In the present study, we investigated the process of establishing a UV lesion. Rats underwent UV irradiation (365 nm wavelength, 2.0 mWh) over the dura, and time-dependent changes in the cortical tissue were analyzed histologically. We found that the majority of neurons in the lesion started to degenerate within 24 hours and the rest disappeared within 5 days after irradiation. UV-induced neuronal degeneration progressed in a layer-dependent manner. Moreover, UV-induced terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) positivity and heme oxygenase-1 (HO-1) immunoreactivity were also detected. These findings suggest that UV irradiation in the brain can induce gradual neural degeneration and oxidative stress. Importantly, UV vulnerability may vary among cortical layers. UV-induced cell death may be due to apoptosis; however, there remains a possibility that UV-irradiated cells were degenerated via processes other than apoptosis. The UV lesion technique will not only assist in investigating brain function at a targeted site but may also serve as a pathophysiological model of focal brain injury and/or neurodegenerative disorders.

Objectives: To perform a systematic study about the contribution of architecture and interior design researchers in studying the effect of physical environment on mental disorders. Background: Mental disorders are a major health problem worldwide and related to severe distress, functional disabilities, and heavy economical burdens. Studies propose that physical environment design can trigger or reduce mental disorder symptoms. However, there is a lack of knowledge about the extent of architectural design research contribution to all types of mental disorder prevention or intervention. Methods: A team of cross-disciplinary researchers gathered information from peer-reviewed manuscripts about the effect of architectural design on enhancing or reducing mental disorder symptoms. Data were collected from manuscripts published between 2008 and 2020 (research related to the topic became clearer in quality and quantity then). Keywords including architecture, interior design, physical environment, and mental disorders were used in the systematic search. Databases were collected using online resources. Numerical data collected from quantitative studies were organized in tables. Results: Our data showed that there were a lot of studies about dementia and autism; few studies about schizophrenia, anxiety, stress-related disorders, and depressive disorders; and no studies about the rest of the mental disorders. General environment followed by housing facility design were the most assessed physical environments for mental disorders. Conclusions: As all mental disorders can have a significant impact on the society, we conclude that architectural studies should focus more on improving or preventing the symptoms of all types of mental disorders through the design of physical environments.
