Integrating Clinical Neuropsychology and Psychotic Spectrum Disorders: A Systematic Analysis of Cognitive Dynamics, Interventions, and Underlying Mechanisms.

Background and Objectives: The study aims to provide a comprehensive neuropsychological analysis of psychotic spectrum disorders, including schizophrenia, bipolar disorder, and depression. It focuses on the critical aspects of cognitive impairments, diagnostic tools, intervention efficacy, and the roles of genetic and environmental factors in these disorders. The paper emphasizes the diagnostic significance of neuropsychological tests in identifying cognitive deficiencies and their predictive value in the early management of psychosis. Materials and Methods: The study involved a systematic literature review following the PRISMA guidelines. The search was conducted in significant databases like Scopus, PsycINFO, PubMed, and Web of Science using keywords relevant to clinical neuropsychology and psychotic spectrum disorders. The inclusion criteria required articles to be in English, published between 2018 and 2023, and pertinent to clinical neuropsychology's application in these disorders. A total of 153 articles were identified, with 44 ultimately included for detailed analysis based on relevance and publication status after screening. Results: The review highlights several key findings, including the diagnostic and prognostic significance of mismatch negativity, neuroprogressive trajectories, cortical thinning in familial high-risk individuals, and distinct illness trajectories within psychosis subgroups. The studies evaluated underline the role of neuropsychological tests in diagnosing psychiatric disorders and emphasize early detection and the effectiveness of intervention strategies based on cognitive and neurobiological markers. Conclusions: The systematic review underscores the importance of investigating the neuropsychological components of psychotic spectrum disorders. It identifies significant cognitive impairments in attention, memory, and executive function, correlating with structural and functional brain abnormalities. The paper stresses the need for precise diagnoses and personalized treatment modalities, highlighting the complex interplay between genetic, environmental, and psychosocial factors. It calls for a deeper understanding of these neuropsychological processes to enhance diagnostic accuracy and therapeutic outcomes.

OBJETIVO: A avaliação neuropsicológica tem alta relevância na adolescência e em situação de conflito com a lei, com privação de liberdade em instituições socioeducativas, pode auxiliar, compondo abordagens psicossociais que identifiquem as funções neuropsicológicas, situando-as a partir da historicidade do indivíduo. Deste modo, para compreender esse problema, foi objetivo desse estudo avaliar e descrever as funções neuropsicológicas de adolescentes meninas privadas de liberdade em instituição socioeducativa. MÉTODOS: As participantes foram 19 meninas avaliadas com os instrumentos: Barratt Scale, Inventário de Expressão de Raiva, teste Wisconsin de classificação de cartas, protocolo neuropsicológico, questionário para uso de drogas e Hare Psychopathy Checklist Revised. RESULTADOS: O uso de drogas na vida ocorreu em 80,0% dos casos. Verificaram-se altos escores de impulsividade total (M=75,8, DP=5,4), traço de raiva (M=24,5, DP=7,3) e respostas perseverativas (M =38,5, DP =19,9). Em conjunto com PCL-R total (M=17,5, DP=3,6) e com QI total (M=79,1, DP=16,2), esses níveis auxiliaram na caracterização das funções de autocontrole. CONCLUSÕES: Os dados foram interpretados como indicativos de baixo funcionamento executivo, altos níveis de raiva, de impulsividade, de uso de drogas e de traços de psicopatia. Foram relatadas adversidades durante a infância, o que pode ter contribuído para um desempenho prejudicado nas funções cognitivas e emocionais dessas meninas.

OBJECTIVE: Neuropsychological assessment is highly relevant in adolescence and in situations of conflict with the law, with deprivation of liberty in socio-educational institutions, it can help, composing psychosocial approaches that identify neuropsychological functions, situating them based on the individual's historicity. Therefore, to understand this problem, the objective of this study was to evaluate and describe the neuropsychological functions of adolescent girls deprived of liberty in a socio-educational institution. METHODS: The participants were 19 girls evaluated with the following instruments: Barratt Scale, Anger Expression Inventory, Wisconsin Card Sorting Test, Neuropsychological protocol, drug use questionnaire and Hare Psychopathy Checklist Revised. RESULTS: Lifetime drug use occurred in 80.0% of cases. There were high scores for total impulsivity (M=75.8, SD=5,4), trait anger (M=24.5, SD=7.3) and perseverative responses (M=38.5, SD=19.9). Together with total PCL-R (M=17.5, SD=3.6) and total IQ (M=79.1, SD=16), these levels helped to characterize self-control functions. CONCLUSIONS: The data were interpreted as indicating low executive functioning, high levels of anger, impulsivity, drug use and psychopathic traits. Adversities were reported during childhood, which may have contributed to impaired performance in the cognitive and emotional functions of these girls.

Neurocognitive Impairment in Post-COVID-19 Condition in Adults: Narrative Review of the Current Literature.

The severe acute respiratory syndrome coronavirus 2 virus has, up to the time of this article, resulted in >770 million cases of COVID-19 illness worldwide, and approximately 7 million deaths, including >1.1 million in the United States. Although defined as a respiratory virus, early in the pandemic, it became apparent that considerable numbers of people recovering from COVID-19 illness experienced persistence or new onset of multi-system health problems, including neurologic and cognitive and behavioral health concerns. Persistent multi-system health problems are defined as Post-COVID-19 Condition (PCC), Post-Acute Sequelae of COVID-19, or Long COVID. A significant number of those with PCC report cognitive problems. This paper reviews the current state of scientific knowledge on persisting cognitive symptoms in adults following COVID-19 illness. A brief history is provided of the emergence of concerns about persisting cognitive problems following COVID-19 illness and the definition of PCC. Methodologic factors that complicate clear understanding of PCC are reviewed. The review then examines research on patterns of cognitive impairment that have been found, factors that may contribute to increased risk, behavioral health variables, and interventions being used to ameliorate persisting symptoms. Finally, recommendations are made about ways neuropsychologists can improve the quality of existing research.

Altered Trajectories: Considering the Long-Term Impact of Educational Disruption during the COVID-19 Pandemic on Neurodevelopment and a Call to Action for Neuropsychology.

OBJECTIVE: The COVID-19 pandemic resulted in educational disruption of historic breadth and duration. The impact of school closures and remote learning have been evaluated in recent studies and reflect critical data for neuropsychologists who routinely assess brain development as it relates to diagnosis, recommendations, and informing public policy. METHOD: Pre-pandemic and contemporaneous literature was summarized, including data on educational disruption and child and adolescent mental health challenges reported during the pandemic, and research on the impact of stress, social isolation, educational achievement, and other factors on brain development during critical developmental windows. RESULTS: Studies indicate that prolonged educational disruption has resulted in attenuated learning gains, most remarkably for those already at risk for educational disparities. Studies have shown increased mental health challenges for youth during the pandemic, with higher rates of mood and eating disorders, and suicidal ideation. Given that some skills develop optimally within specific time periods, pandemic-related disruption has likely contributed to altered developmental trajectories. CONCLUSION: Trajectory of neuropsychological development of children and adolescents, especially marginalized students, may be affected by effects on learning and mental health due to prolonged educational disruption and psychological stressors. Evaluation and treatment may be delayed due to backlog and increased demand. Clinical neuropsychological practice recommendations are presented with a call to action for the field in moving forward flexibly to increase access to evaluation services.

Digital Neuropsychology beyond Computerized Cognitive Assessment: Applications of Novel Digital Technologies.

Compared with other health disciplines, there is a stagnation in technological innovation in the field of clinical neuropsychology. Traditional paper-and-pencil tests have a number of shortcomings, such as low-frequency data collection and limitations in ecological validity. While computerized cognitive assessment may help overcome some of these issues, current computerized paradigms do not address the majority of these limitations. In this paper, we review recent literature on the applications of novel digital health approaches, including ecological momentary assessment, smartphone-based assessment and sensors, wearable devices, passive driving sensors, smart homes, voice biomarkers, and electronic health record mining, in neurological populations. We describe how each digital tool may be applied to neurologic care and overcome limitations of traditional neuropsychological assessment. Ethical considerations, limitations of current research, as well as our proposed future of neuropsychological practice are also discussed.

Fractals in Neuropsychology and Cognitive Neuroscience.

The fractal dimension of cognition refers to the idea that the cognitive processes of the human brain exhibit fractal properties. This means that certain patterns of cognitive activity, such as visual perception, memory, language, or problem-solving, can be described using the mathematical concept of fractal dimension.The idea that cognition is fractal has been proposed by some researchers as a way to understand the complex, self-similar nature of the human brain. However, it's a relatively new idea and is still under investigation, so it's not yet clear to what extent cognitive processes exhibit fractal properties or what implications this might have for our understanding of the brain and clinical practice. Indeed, the mission of the "fractal neuroscience" field is to define the characteristics of fractality in human cognition in order to differently characterize the emergence of brain disorders.

From Practice to Public Health: Broadening Neuropsychology's Reach & Value-An Introduction to the National Academy of Neuropsychology's 2022 Annual Conference Special Issue.

This special issue is centered around presentations from the National Academy of Neuropsychology 2022 Annual Conference. The theme of the conference, "From Practice to Public Health: Broadening Neuropsychology's Reach & Value" is pivotal for the field's future. With an ever-shifting technological landscape and recent changes in clinical practice post-COVID, we are left wondering how neuropsychology will develop. How will we use biomedical and technological advances, such as blood-based Alzheimer's disease biomarkers or passive digital recordings, to improve clinical care and further expand our understanding of disease mechanisms? As neuropsychologists, how can we use our expertise to empirically inform public health policy? The diagnosis and treatment of post-acute sequelae of COVID-19, the identification and characterization of post-pandemic educational setbacks, and the adaptation of new technological and diagnostic advances into clinical practice workflows represent a vital set of new challenges and opportunities poised to disrupt traditional modes of practice. The articles in this special issue convey the role of neuropsychology in addressing these emerging issues and illustrate how and why neuropsychology is well positioned to be at the forefront of clinical practice and scientific advancements.

Plasma biomarkers for Alzheimer's and related dementias: A review and outlook for clinical neuropsychology.

Recent technological advances have improved the sensitivity and specificity of blood-based biomarkers for Alzheimer's disease and related dementias. Accurate quantification of amyloid-ß peptide, phosphorylated tau (pTau) isoforms, as well as markers of neurodegeneration (neurofilament light chain [NfL]) and neuro-immune activation (glial fibrillary acidic protein [GFAP] and chitinase-3-like protein 1 [YKL-40]) in blood has allowed researchers to characterize neurobiological processes at scale in a cost-effective and minimally invasive manner. Although currently used primarily for research purposes, these blood-based biomarkers have the potential to be highly impactful in the clinical setting - aiding in diagnosis, predicting disease risk, and monitoring disease progression. Whereas plasma NfL has shown promise as a non-specific marker of neuronal injury, plasma pTau181, pTau217, pTau231, and GFAP have demonstrated desirable levels of sensitivity and specificity for identification of individuals with Alzheimer's disease pathology and Alzheimer's dementia. In this forward looking review, we (i) provide an overview of the most commonly used blood-based biomarkers for Alzheimer's disease and related dementias, (ii) discuss how comorbid medical conditions, demographic, and genetic factors can inform the interpretation of these biomarkers, (iii) describe ongoing efforts to move blood-based biomarkers into the clinic, and (iv) highlight the central role that clinical neuropsychologists may play in contextualizing and communicating blood-based biomarker results for patients.

[The role of the neuropsychologist in Parkinson's disease]. / Le rôle du psychologue spécialisé en neuropsychologie dans la maladie de Parkinson.

Psychologists specializing in neuropsychology, more commonly known as neuropsychologists, play an important role in the care of cognitive, behavioral and emotional aspects of patients with Parkinson's disease. They are also involved in research and public education on the disease.

Opening new vistas on obsessive-compulsive disorder with the observing response task.

Obsessive-compulsive disorder (OCD), a highly prevalent and debilitating disorder, is incompletely understood in terms of underpinning behavioural, psychological, and neural mechanisms. This is attributable to high symptomatic heterogeneity; cardinal features comprise obsessions and compulsions, including clinical subcategories. While obsessive and intrusive thoughts are arguably unique to humans, dysfunctional behaviours analogous to those seen in clinical OCD have been examined in nonhuman animals. Genetic, ethological, pharmacological, and neurobehavioural approaches all contribute to understanding the emergence and persistence of compulsive behaviour. One behaviour of particular interest is maladaptive checking, whereby human patients excessively perform checking rituals despite these serving no purpose. Dysfunctional and excessive checking is the most common symptom associated with OCD and can be readily operationalised in rodents. This review considers animal models of OCD, the neural circuitries associated with impairments in habit-based and goal-directed behaviour, and how these may link to the compulsions observed in OCD. We further review the Observing Response Task (ORT), an appetitive instrumental learning procedure that distinguishes between functional and dysfunctional checking, with translational application in humans and rodents. By shedding light on the psychological and neural bases of compulsive-like checking, the ORT has potential to offer translational insights into the underlying mechanisms of OCD, in addition to being a platform for testing psychological and neurochemical treatment approaches.

Competencies unique to clinical neuropsychology: A consensus statement of educators, practitioners, and professional leaders in Australia.

Objective: To delineate the unique role of clinical neuropsychologists in contemporary Australian clinical practice and present a comprehensive consensus-based set of clinical neuropsychology competencies to guide and standardize the training of clinical neuropsychologists. Method: Twenty-four national representatives of the clinical neuropsychology profession (71% female, M = 20.1, SD = 8.1 years clinical practice), including tertiary-level educators, senior practitioners and members of the executive committee of the peak national neuropsychology body, formed the Australian Neuropsychology Alliance of Training and Practice Leaders (ANATPL). Informed by a review of existing international competency frameworks and Australian Indigenous psychology education frameworks, a provisional set of competencies for clinical neuropsychology training and practice were developed, followed by 11 rounds of feedback and revisions. Results: The final set of clinical neuropsychology competencies achieved full consensus and falls into three broad categories: generic foundational (i.e. general professional psychology competencies applied to clinical neuropsychology); specific functional (i.e. specific to clinical neuropsychology areas of practice) competencies relevant to all career stages; and functional competencies relevant to advanced career stages. Competencies span a number of knowledge and skill-based domains including neuropsychological models and syndromes, neuropsychological assessment, neuropsychological intervention, consultation, teaching/supervision and management/administration. Conclusion: The competencies reflect recent advances in the field of clinical neuropsychology, including expanded intervention competencies, culturally-informed neuropsychological practice and use of emerging technologies. They will be available as a resource to guide curriculum development for clinical training, as well as providing a useful framework for professional practice and advocacy more broadly within the discipline of clinical neuropsychology.

[Formula: see text] The multifaceted role of neuropsychology in pediatric solid organ transplant: preliminary guidelines and strategies for clinical practice.

The incidence of pediatric solid organ transplantation (SOT) has increased in recent decades due to medical and surgical advances as well as improvements in organ procurement. Survival rates for pediatric kidney, liver, and heart transplantation are above 85% but patients continue to experience complex healthcare needs over their lifetime. Long-term developmental and neuropsychological sequelae are becoming increasingly recognized in this population, although preliminary work is limited and deserves further attention. Neuropsychological weaknesses are often present prior to transplantation and may be related to underlying congenital conditions as well as downstream impact of the indicating organ dysfunction on the central nervous system. Neuropsychological difficulties pose risk for functional complications, including disruption to adaptive skill development, social-emotional functioning, quality of life, and transition to adulthood. The impact of cognitive dysfunction on health management activities (e.g., medication adherence, medical decision-making) is also an important consideration given these patients' lifelong medical needs. The primary aim of this paper is to provide preliminary guidelines and clinical strategies for assessment of neuropsychological outcomes across SOT populations for pediatric neuropsychologists and the multidisciplinary medical team, including detailing unique and shared etiologies and risk factors for impairment across organ types, and functional implications. Recommendations for clinical neuropsychological monitoring as well as multidisciplinary collaboration within pediatric SOT teams are also provided.

To confirm your appointment, please press one: Examining demographic and health system interface factors that predict missed appointments in a pediatric outpatient neuropsychology clinic.

Objective: Missed patient appointments have a substantial negative impact on patient care, child health and well-being, and clinic functioning. This study aims to identify health system interface and child/family demographic characteristics as potential predictors of appointment attendance in a pediatric outpatient neuropsychology clinic. Method: Pediatric patients (N = 6,976 across 13,362 scheduled appointments) who attended versus missed scheduled appointments at a large, urban assessment clinic were compared on a broad array of factors extracted from the medical record, and the cumulative impact of significant risk factors was examined. Results: In the final multivariate logistic regression model, health system interface factors that significantly predicted more missed appointments included a higher percentage of previous missed appointments within the broader medical center, missing pre-visit intake paperwork, assessment/testing appointment type, and visit timing relative to the COVID-19 pandemic (i.e. more missed appointments prior to the pandemic). Demographic characteristics that significantly predicted more missed appointments in the final model included Medicaid (medical assistance) insurance and greater neighborhood disadvantage per the Area Deprivation Index (ADI). Waitlist length, referral source, season, format (telehealth vs. in-person), need for interpreter, language, and age were not predictive of appointment attendance. Taken together, 7.75% of patients with zero risk factors missed their appointment, while 22.30% of patients with five risk factors missed their appointment. Conclusions: Pediatric neuropsychology clinics have a unique array of factors that impact successful attendance, and identification of these factors can help inform policies, clinic procedures, and strategies to decrease barriers, and thus increase appointment attendance, in similar settings.

Parental, caregiving, and family leave during clinical neuropsychology postdoctoral training: Recommendations and guidelines from the Women in Neuropsychology (WIN) committee and Education Advisory Committee (EAC) of the Society for Clinical Neuropsychology (SCN; APA division 40).

Objective: Parental and other caregiving leave is important to postdoctoral fellows, yet there is no field-wide recommendation for leave policies among clinical neuropsychology postdoctoral training programs, which is of particular relevance given the two-year requirement for eligibility for board certification. The aims of this manuscript are to (a) discuss general guidelines and recommendations for leave policies, both informed by prior empirical evidence as well as relevant existing policy guidelines from various academic and healthcare organizations, and (b) use vignettes to provide possible solutions for potential leave scenarios. Method: A critical review of literature on family leave from public policy and political science, industrial-organizational psychology, academic medicine, and psychology was conducted and findings were synthesized. Results and Conclusions: Fellowship training programs are encouraged to adopt a competency-based model that permits flexibility in leave during training without necessarily requiring an extended end date. Programs should adopt clear policies and make this information readily available to trainees and think flexibly about training options that best meet the training needs and goals of each individual. We also encourage neuropsychologists at all levels to engage in advocacy for broader systemic supports of trainees seeking equitable family leave.

A retrospective analysis of the ethnicity of individuals referred to a tertiary neuropsychology service in the United Kingdom.

Objective: Ethnic minorities comprise approximately 18% of the UK population and are at high risk of developing neurological conditions. Despite this, there is little information regarding their access to neuropsychology services. This study evaluated whether ethnic minorities were proportionally represented in a tertiary neuropsychology department in the UK in accordance with census data for the region. We also aimed to highlight which ethnic groups were over- and underrepresented. Method: Anonymised demographic data of 3429 outpatient and 3304 inpatient referrals to an adult UK neuropsychology department was collected. These data were compared to the 2021 UK census data for the region. Results: Ethnicities in both the outpatient referrals (χ2(15) = 24066.55, p < .001) and inpatient referrals (χ2(15) = 35940924.75, p < .001) are significantly different from the Census. All ethnic minorities were underrepresented in adult neuropsychology referral data for both outpatient settings (-0.06% to -4.66%) and inpatient settings (-0.01% to -4.99%). Pakistani individuals were the most underrepresented across all settings, followed by individuals from an African background. Conversely, individuals of White British ethnicity were overrepresented in both outpatient settings (+10.73%) and inpatient settings (+15.68%). Conclusions: The UK ethnic minorities were not referred to a neuropsychology service relative to regional population prevalence. This contradicts their increased susceptibility for risk of neurological conditions but may also indicate the inaccessibility of neuroscience services for ethnic minorities. Replicating this study across different regions and gathering data on prevalence rates for different neurological conditions across ethnicity is recommended. Additionally, improving accessibility of neuropsychology services for British ethnic minorities should be prioritised.

Effectiveness of teleneuropsychological rehabilitation: Systematic review of randomized controlled trials.

OBJECTIVE: The effectiveness of neuropsychological rehabilitation is supported by the evidence found in previous reviews, but there is a lack of research regarding the effectiveness of remotely conducted neuropsychological rehabilitation. This review aimed to identify and evaluate the results of studies investigating the effectiveness of teleneuropsychological rehabilitation. METHODS: Relevant articles were extracted from electronic databases and filtered to include studies published in 2016 or later to focus on recent practices. Data were synthesized narratively. RESULTS: A total of 14 randomized controlled studies were included in the synthesis (9 for children/adolescents, 5 for adults). The most common type of intervention was computerized cognitive training with regular remote contact with the therapist (seven studies). Regarding children and adolescents, the evidence for the effectiveness was found only for these types of interventions with improvements in cognitive outcomes. The results regarding the family-centered interventions were mixed with improvements only found in psychosocial outcomes. No support was found for the effectiveness of interventions combining cognitive and motor training. Regarding adults, all included studies offered support for the effectiveness, at least to some extent. There were improvements particularly in trained cognitive functions. Long-term effects of the interventions with generalization to global functioning remained somewhat unclear. CONCLUSION: Remote interventions focused on computerized cognitive training are promising methods within teleneuropsychological rehabilitation. However, their impact on long-term meaningful, everyday functioning remained unclear. More research is needed to reliably assess the effectiveness of teleneuropsychological interventions, especially with more comprehensive approaches.
