"Brain Fog" After COVID-19 Infection: How the Field of Neuropsychology Can Help Clear the Air.

The chapter explores the role of neuropsychology in understanding brain fog as a subjective complaint in the context of COVID-19. It discusses the historical and medical significance of the term "brain fog" and its psychological and neurological aspects. The chapter identifies the cognitive domains commonly affected by brain fog, such as attention, executive function, memory, and language. Additionally, it emphasizes the impact of societal changes during the COVID-19 pandemic on the general population as a crucial backdrop for understanding the issue. The chapter also highlights the important role of clinical and research neuropsychologists in gaining clarity on grouped data and individual patients' cognitive and emotional difficulties after COVID-19 infection. It discusses indications for neuropsychological rehabilitation and therapy and describes typical therapy phases and methods, including new approaches like telemedicine, virtual reality, and mobile app-based rehabilitation and self-tracking. The chapter underscores that experiences of brain fog can vary among COVID-19 patients and may change over time. It provides clinicians and interested parties with an in-depth understanding of brain fog and its manifestations, concomitant subtypes, and concrete strategies for addressing it. The chapter emphasizes the critical role of neuropsychology in scientifically examining brain fog and advocating for personalized approaches to cognitive rehabilitation.

Advances in semantic dementia: Neuropsychology, pathology & neuroimaging.

Semantic dementia is a kind of neurodegenerative disorder, characterized by prominent semantic impairments and anterior temporal lobe atrophy. Since 2010, more studies have devoted to this rare disorder, revealing that it is more complex than we think. Clinical advances include more specific findings of semantic impairments and other higher order cognitive deficits. Neuroimaging techniques can help revealing the different brain networks affected (both structurally and functionally) in this condition. Pathological and genetic studies have also found more complex situations of semantic dementia, which might explain the huge variance existing in semantic dementia. Moreover, the current diagnosis criteria mainly focus on semantic dementia's classical prototype. We further delineated the features of three subtypes of semantic dementia based on atrophy lateralization with three severity stages. In a broader background, as a part of the continuum of neurodegenerative disorders, semantic dementia is commonly compared with other resembling conditions. Therefore, we summarized the differential diagnosis between semantic dementia and them. Finally, we introduced the challenges and achievements of its diagnosis, treatment, care and cross cultural comparison. By providing a comprehensive picture of semantic dementia on different aspects of advances, we hope to deepen the understanding of semantic dementia and promote more inspirations on both clinical and theoretical studies about it.

Exploring cultural contributions to the neuropsychology of social cognition: the advanced clinical solutions.

INTRODUCTION: Culture and social cognition are deeply intertwined, yet how this rich intersectionality is expressed neuropsychologically remains an important question. METHOD: In a convenience sample of 128 young adults (mean age = 24.9 years) recruited from a majority-minority urban university, we examined performance-based neuropsychological measures of social cognition, the Advanced Clinical Solutions-Social Perception (ACS-SP), in relation to both cultural orientation, as assessed by the Individualism-Collectivism Scale (ICS) and spoken English language, as assessed by the oral word pronunciation measure of the Wide Range Achievement Test-4 (WRAT4). RESULTS: Results indicated higher WRAT4 scores correlated with better performance across all ACS-SP measures of social cognition. Controlling for these associations in spoken English, partial correlations linked lower scores across both prosody interpretation and affect naming ACS-SP tasks with a propensity to view social relationships vertically, irrespective of individualistic or collectivistic orientations. Hierarchical regression results showed that cultural orientation and English-language familiarity each specifically and uniquely contributed to ACS-SP performance for matching prosody with facial expressions. CONCLUSIONS: These findings underscore the importance of incorporating and prioritizing both language and cultural factors in neuropsychological studies of social cognition. They may be viewed as offering strong support for expanding the boundaries of the construct of social cognition beyond its current theoretical framework of one that privileges Western, educated, industralized, rich and democratic (WEIRD) values, customs, and epistemologies.

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.

Forensic neuropsychological assessment.

With its firm establishment as a neuropsychology subspecialty, forensic neuropsychological assessment is integral to many criminal and civil forensic evaluations. In addition to evaluating cognitive deficits, forensic neuropsychologists can provide reliable information regarding symptom magnification, malingering, and other neurocognitive and psychological issues that may impact the outcome of a particular legal case. This article is an overview and introduction to neuropsychological assessment in the forensic mental health context. Major issues impacting the current practice of forensic neuropsychology are summarized, and several examples from case law are highlighted.

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.

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.

Representation of women in neuropsychology research prior to the COVID-19 pandemic.

OBJECTIVE: Prior work has demonstrated that women have been historically underrepresented across various research fields, including neuropsychology. Given these disparities, the goal of this study was to systematically evaluate the inclusion of women as participants in neuropsychology research. The current study builds upon previous research by examining articles from eight peer-reviewed neuropsychology journals published in 2019. METHOD: Empirical articles examining human samples were included in the current review if they were available in English. Eligible articles were examined to glean whether the main topic of the article was related to a gender issue, how gender was categorized, the gender distribution of the sample, whether gender was considered in analyses, whether gender was addressed in the discussion, and what age categories the study examined. RESULTS: There was a relatively even distribution of men (51.76%) and women (48.24%) in neuropsychological research studies reviewed. There were twice as many studies that included only men compared to only women (16 vs. 8 studies), and nearly twice as many studies consisted of ≥ 75% men (16.6%) compared to ≥75% of women (8.5%). Gender-focused research was limited (3%). Furthermore, gender was frequently disregarded in analyses (58%) and often not addressed in the discussion (75%). CONCLUSIONS: The current study highlights the limitations within neuropsychology related to the representation of women in research. Although it is encouraging that neuropsychological research is generally inclusive of women participants, future research should aim to more comprehensively investigate how gender may influence cognitive risk and resilience factors across different clinical presentations. Recommendations to begin addressing this challenge and to move toward more gender-equitable research are provided.

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.

The role of psychology and neuropsychology in pediatric epilepsy surgery evaluation.

Epilepsy is one of the most common neurological problems affecting 470,000 children in the United States. While most youth will achieve seizure freedom using medication, up to a third will continue to have seizures and are therefore considered to have drug-resistant epilepsy (DRE). Children and adolescents with epilepsy are at higher risk of behavioral, cognitive, and emotional disorders. Youth with DRE are at even greater risk of behavioral and emotional problems impacting quality of life and may need to pursue surgical interventions, including resective surgery or device implantation. Due to advances in the evaluation of candidates and surgical options, epilepsy surgery is more effective and has become second-line treatment for youth with DRE. This paper highlights the importance of exploring, assessing, and treating psychological and neuropsychological factors throughout the three phases of the epilepsy surgery process and ways pediatricians can support youth and families.

Ejecución neuropsicológica y carga de enfermedad en sujetos en riesgo de desarrollar enfermedad de Huntington / Neuropsychological performance and disease burden in individuals at risk of developing Huntington disease

Introducción La enfermedad de Huntington (EH) es un trastorno neurodegenerativo y hereditario. Gracias al diagnóstico predictivo se han descrito características clínicas incipientes en la fase prodrómica. Objetivo Comparar la ejecución en tareas cognitivas de portadores (PEH) del gen de la huntingtina y no portadores (NPEH) y observar la variabilidad en la ejecución, dependiendo de la carga de la enfermedad y cercanía a la etapa manifiesta (edad de inicio de los síntomas). Método Los 146 participantes de un Programa de Diagnóstico Predictivo de EH (PDP-EH) fueron divididos en PEH (41,1%) y NPEH (58,9%). Mediante fórmulas matemáticas se obtuvo la carga de enfermedad y cercanía a la etapa manifiesta en el grupo PEH y se correlacionó con la ejecución neuropsicológica. Resultados Se observaron diferencias significativas entre los grupos con las pruebas Mini-Mental State Examination (MMSE), Stroop-B, SDMT y fluidez fonológica. En el grupo PEH se observaron correlaciones entre la carga de enfermedad con la MMSE, Stroop-B y SDMT. El grupo «Cerca» de la etapa manifiesta es el que obtuvo la puntuación más baja en las pruebas MMSE, Stroop-B, Stroop-C, SDMT y fluidez verbal semántica. De acuerdo al MANCOVA, el efecto MMSE evidencia diferencias estadísticamente significativas entre carga de la enfermedad y la cercanía de inicio de los síntomas. Conclusiones Se observa un nivel menor de desempeño en el grupo PEH con probabilidad de inicio cercano de la fase manifiesta en pruebas que evalúan la velocidad de procesamiento y atención. La disfunción cognitiva prefrontal se altera de manera precoz varios años antes del diagnóstico motor de la EH. (AU)

Introduction Huntington disease (HD) is a hereditary neurodegenerative disorder. Thanks to predictive diagnosis, incipient clinical characteristics have been described in the prodromal phase. Objective To compare performance in cognitive tasks of carriers (HDC) and non-carriers (non-HDC) of the huntingtin gene and to analyse the variability in performance as a function of disease burden and proximity to the manifest stage (age of symptom onset). Method A sample of 146 participants in a predictive diagnosis of HD programme were divided into the HDC (41.1%) and non-HDC groups (58.9%). Mathematical formulae were used to calculate disease burden and proximity to the manifest stage in the HDC group; these parameters were correlated with neuropsychological performance. Results Significant differences were observed between groups in performance on the Mini-Mental State Examination (MMSE), Stroop-B, Symbol-Digit Modalities Test (SDMT), and phonological fluency. In the HDC group, correlations were observed between disease burden and performance on the MMSE, Stroop-B, and SDMT. The group of patients close to the manifest stage scored lowest on the MMSE, Stroop-B, Stroop-C, SDMT, and semantic verbal fluency. According to the multivariate analysis of covariance, the MMSE effect shows statistically significant differences in disease burden and proximity to onset of symptoms. Conclusions Members of the HDC group close to the manifest phase performed more poorly on tests assessing information processing speed and attention. Prefrontal cognitive dysfunction appears early, several years before the motor diagnosis of HD. (AU)

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.

[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.

A digital teleneuropsychology platform for the diagnosis of mild cognitive impairment: from concept to certification as a medical device.

BACKGROUND: Innovative digital solutions are shaping a new concept of dementia care, opening additional venues for prevention, diagnosis, monitoring and treatment. Hereby, we report the development of a tablet-based teleneuropsychology platform (Tenèpsia®), from concept to certification as Medical Device (MD) Class IIA, as per new MD regulation 745/2017. METHODS: The platform was designed for the remote cognitive evaluation and created thanks to the effort of a collaborative working group including experts from three Italian scientific societies and Biogen Italia S.r.l. (hereafter "Biogen"), and developers from Xenia Reply and Inside AI. The development strategy was guided by converting traditional paper-and-pencil tests into digital versions while maintaining comparable neuropsychological features and optimizing patient accessibility and user experience. The experts focused on the choice and adaptation of traditional neuropsychology measures for a 45-min teleneuropsychology assessment. RESULTS: The developers created a web and a mobile interface, respectively, for the professional (neuropsychologist) and non-professional (patient and caregiver) use. Recording of voice, drawing and typing information was enabled. Instant dashboards provide a quick overview of the patient's condition. Simulation activities were performed to obtain MD certification, valid across Europe. CONCLUSION: Neuropsychology services will benefit from the implementation in clinics of harmonized digital tools with adequate scientific and technological standards. The use of digital cognitive testing for the diagnosis of mild cognitive impairment is expected to enhance patient and clinician outcomes through simplified, digital objective data collection, sparing of time and resources, with a positive impact on healthcare costs and access to treatments, reducing inequalities and delays in diagnosis and cure.
