Technology meets tradition: a hybrid model for implementing digital tools in neuropsychology.

The COVID-19 pandemic has significantly impacted the provision of mental health care services and the ability to provide neuropsychological evaluations. The inability to conduct traditional evaluations has left neuropsychologists with the unprecedented task of determining how to modify existing paradigms while balancing the need to provide services and adhere to safety parameters. The COVID-19 literature suggests clinicians are modifying their evaluations based on the following models: (1) continuing to administer in-person evaluations; (2) discontinuing all evaluations due to issues related to standardization, test security, and patient-specific characteristics; (3) conducting virtual evaluations; and/or (4) adopting a hybrid model incorporating both traditional and technology-based modalities. Given the challenges with models 1-3, along with the modifications in telehealth guidelines and insurance reimbursement rates, neuropsychologists are more poised than ever to solidify the implementation of a hybrid model that lasts beyond COVID-19. We introduce the term Hybrid Neuropsychology, a model for the future of neuropsychological evaluations that includes three Action Items: (1) building a technology-based practice; (2) integrating data science; and (3) engaging with innovators in other fields. Hybrid Neuropsychology will enable clinicians to effectively modernize their practice, improve health care equity, and ensure neuropsychology secures its place in a technology-based world.

Neuropsychological Assessment: Past and Future.

Neuropsychological assessment tools are the staple of our field. The development of standardized metrics sensitive to brain-behavior relationships has shaped the neuropsychological questions we can ask, our understanding of discrete brain functions, and has informed the detection and treatment of neurological disorders. We identify key turning points and innovations in neuropsychological assessment over the past 40-50 years that highlight how the tools used in common practice today came to be. Also selected for emphasis are several exciting lines of research and novel approaches that are underway to further probe and characterize brain functions to enhance diagnostic and treatment outcomes. We provide a brief historical review of different clinical neuropsychological assessment approaches (Lurian, Flexible and Fixed Batteries, Boston Process Approach) and critical developments that have influenced their interpretation (normative standards, cultural considerations, longitudinal change, common metric batteries, and translational assessment constructs). Lastly, we discuss growing trends in assessment including technological advances, efforts to integrate neuropsychology across disciplines (e.g., primary care), and changes in neuropsychological assessment infrastructure. Neuropsychological assessment has undergone massive growth in the past several decades. Nonetheless, there remain many unanswered questions and future challenges to better support measurement tools and translate assessment findings into meaningful recommendations and treatments. As technology and our understanding of brain function advance, efforts to support infrastructure for both traditional and novel assessment approaches and integration of complementary brain assessment tools from other disciplines will be integral to inform brain health treatments and promote the growth of our field.

The Neuropsychology of Traumatic Brain Injury: Looking Back, Peering Ahead.

The past 50 years have been a period of exciting progress in neuropsychological research on traumatic brain injury (TBI). Neuropsychologists and neuropsychological testing have played a critical role in these advances. This study looks back at three major scientific advances in research on TBI that have been critical in pushing the field forward over the past several decades: The advent of modern neuroimaging; the recognition of the importance of non-injury factors in determining recovery from TBI; and the growth of cognitive rehabilitation. Thanks to these advances, we now have a better understanding of the pathophysiology of TBI and how recovery from the injury is also shaped by pre-injury, comorbid, and contextual factors, and we also have increasing evidence that active interventions, including cognitive rehabilitation, can help to promote better outcomes. The study also peers ahead to discern two important directions that seem destined to influence research on TBI over the next 50 years: the development of large, multi-site observational studies and randomized controlled trials, bolstered by international research consortia and the adoption of common data elements; and attempts to translate research into health care and health policy by the application of rigorous methods drawn from implementation science. Future research shaped by these trends should provide critical evidence regarding the outcomes of TBI and its treatment, and should help to disseminate and implement the knowledge gained from research to the betterment of the quality of life of persons with TBI. (JINS, 2017, 23, 806-817).

Neuropsychology of Learning Disabilities: The Past and the Future.

Over the past 50 years, research on children and adults with learning disabilities has seen significant advances. Neuropsychological research historically focused on the administration of tests sensitive to brain dysfunction to identify putative neural mechanisms underlying learning disabilities that would serve as the basis for treatment. Led by research on classifying and identifying learning disabilities, four pivotal changes in research paradigms have produced a contemporary scientific, interdisciplinary, and international understanding of these disabilities. These changes are (1) the emergence of cognitive science, (2) the development of quantitative and molecular genetics, (3) the advent of noninvasive structural and functional neuroimaging, and (4) experimental trials of interventions focused on improving academic skills and addressing comorbid conditions. Implications for practice indicate a need to move neuropsychological assessment away from a primary focus on systematic, comprehensive assessment of cognitive skills toward more targeted performance-based assessments of academic achievement, comorbid conditions, and intervention response that lead directly to evidence-based treatment plans. Future research will continue to cross disciplinary boundaries to address questions regarding the interaction of neurobiological and contextual variables, the importance of individual differences in treatment response, and an expanded research base on (a) the most severe cases, (b) older people with LDs, and (c) domains of math problem solving, reading comprehension, and written expression. (JINS, 2017, 23, 930-940).

Facilitating Autism Research.

Early autism research focused on behavior and cognition. In recent decades, the pace of research has accelerated, and advances in imaging and genetics have allowed the accumulation of biological data. Nevertheless, a coherent picture of the syndrome at either phenotypic or biological level has not emerged. We see two fundamental obstacles to progress in basic understanding of autism. First, the two defining features (impairment in social interactions and communication, and restricted, repetitive behaviors and interests) are historically seen as integrally related. Others hold that these two major traits are fractionable and must be studied independently, casting doubt on autism as a coherent syndrome. Second, despite much recent research on brain structure and function, environmental factors, and genetics/genomics, findings on the biological level have not generally aligned well with those on the phenotypic level. In the first two sections, we explore these challenges, and in the third section, we review approaches that may facilitate progress, such as (1) including in studies all individuals defined by social impairment without regard to repetitive behaviors, (2) forming narrowly defined subtypes by thorough characterization on specific features, both diagnostic and non-diagnostic, (3) focusing on characteristics that may be relatively robust to environmental influence, (4) studying children as early as possible, minimizing environmental influence, and including longitudinal course as an important part of the phenotype, (5) subtyping by environmental risk factors, (6) distinguishing between what participants can do and what they typically do, and (7) aggregating large data sets across sites. (JINS, 2017, 23, 903-915).

Potential implications of Luria's work for the neuropsychology of epilepsy and epilepsy surgery: A perspective for re-examination.

The pioneeristic work of Alexander Romanovic Luria into the field of human neuropsychology offered eminent contributions to clinical praxis by providing theory guided methods and instruments for the study of higher cortical functions. However, lots of this knowledge corpus either remains untranslated and thus inaccessible, or in some cases selectively overlooked by academic authorities and consequently not passed to the future generations of experts. Although Luria was not exclusively devoted to the study of epilepsy, his theories and clinical approaches actually penetrate the whole neuropathology spectrum. His holistic and systemic approach to the brain sounds nowadays more than opportune and consistent with the network approach of the modern neuroimaging era. As to epilepsy, the logic underlying the Lurian approach (cognitive functions organized into complex functional systems with intra- and/or inter-hemispheric distribution, as opposed to the modularistic view of the brain) seems consistent with our current knowledge in epileptology with respect to epileptic networks, as well as the modern construct of the functional deficit zone. These contributions seem to be highly promising for the neuropsychology of epilepsy and epilepsy surgery, since they provide clinicians with valuable methods and theories to assist them in the localization -and lateralization- of cognitive deficits. Consequently they are of great applicability in the context of the preoperative neuropsychological monitoring of patients candidates for epilepsy surgery, where neuropsychologist are called upon to provide surgeons with anatomical data.

The Evolution of Psychology as a Basic Bio-behavioral Science in Healthcare Education.

For over a century, researchers and educators have called for the integration of psychological science into medical school curricula, but such efforts have been impeded by barriers within medicine and psychology. In addressing these barriers, Psychology has re-examined its relationship to Medicine, incorporated psychological practices into health care, and redefined its parameters as a science. In response to interdisciplinary research into the mechanisms of bio-behavioral interaction, Psychology evolved from an ancillary social science to a bio-behavioral science that is fundamental to medicine and health care. However, in recent medical school curriculum innovations, psychological science is being reduced to a set of "clinical skills," and once again viewed as an ancillary social science. These developments warrant concern and consideration of new approaches to integrating psychological science in medical education.

Vascular cognitive impairment: Advances and trends.

The presence of vascular neurocognitive impairment (whatever the severity) is always associated with a functional impact and increased risk of dependency and institutionalization. However, vascular cognitive impairment remains underdiagnosed, and the mechanisms underlying post-stroke cognitive disorders are still poorly understood. However, the advent of new criteria and a standardized international neuropsychological battery is expected to lead to improved diagnosis and management, and the development of novel techniques (such as brain imaging and amyloid PET) should improve our understanding of the mechanisms underlying vascular cognitive impairment and help to identify potential targets for therapy.

[Towards a neuropsychological approach to autism] / Vers un abord neuro-psychologique de l'autisme.

Neuropsychology attributes mental activity to brain functioning. An inventory of the every-day life of the autist confirms a breakdown in behavior adapted to the world around him. Deficiency in the contribution of the right hemisphere, compromising social life, is accompanied by a mental life that is detached from reality, favorizing preconceived ideas that are inscribed in the logic governing the left hemispheric function. Inside each hemisphere homologous areas of the cerebral cortex, receiving and sharing the same information, react to messages according to their own mode. The left hemisphere applies itself to elementary information, treated sequentially, while the right hemisphere continuously brings up to date temporal and spatial synthesis coming from the sensorale contribution. Attachment to an object or attentiveness to the world: this alternative mode is the key to understanding. The disorder responsible for autism occurs in the perinatal period. It compromizes the maturation of right hemisphere functions where interaction with the surrounding environment should take precedence over attention to objects. Besides its interest in the orientation of research, the neuropsychological approach of Pervasive Development Disorder has the merit of demystifying the drama associated with autism. A better understanding of the nature of this disorder would be of great assistance in circumventing it.

A single standard for memory: the case for reconsolidation.

Consolidated memories can re-enter states of transient instability following reactivation, from which they must again stabilize in order to persist, contradicting the previously dominant view that memory and its associated plasticity mechanisms progressively and irreversibly decline with time. We witness exciting times, as neuroscience begins embracing a position, long-held in cognitive psychology, that recognizes memory as a principally dynamic process. In light of remaining controversy, we here establish that the same operational definitions and types of evidence underpin the deduction of both reconsolidation and consolidation, thus validating the extrapolation that post-retrieval memory plasticity reflects processes akin to those that stabilized the memory following acquisition.

The foundations of next generation attention-deficit/hyperactivity disorder neuropsychology: building on progress during the last 30 years.

In this short overview we have illustrated 30 years of progress in the field of ADHD neuropsychology through a selective presentation of studies published in the JCPP. Clearly this is not an exhaustive list of papers (we had to leave many excellent studies out) and obviously many studies published in other journals have had an equally significant impact on the field. Nevertheless, it is clear that the JCPP has contributed in important ways to providing the empirical and intellectual foundations of the next generation of ADHD neuropsychological models in terms of insight regarding context dependence, complexity and heterogeneity, and diagnostic specificity and sensitivity. Furthermore, articles have highlighted the importance of a developmental perspective on neuropsychological deficits in ADHD as well as the possibility that they could be targeted with new and novel treatments. Our hope is that we will continue to witness similar growth in understanding over the next 30 years, and that the JCPP will continue to be at the forefront of this progress.

A neuroscience agenda for counseling psychology research.

Recent advances in the field of neuroscience have dramatically changed our understanding of brain-behavior relationships. In this article, we illustrate how neuroscience can provide a conceptual and methodological framework to understand our clients within a transdiagnostic developmental perspective. We provide directions for integrating neuroscience into future process and outcome research. We present examples on how neuroscience can be integrated into researching the effects of contextual counseling interventions. We posit that interpersonal and environmental factors, such as neurotoxic factors (e.g., emotional neglect, stress), positive neurodevelopmental factors (e.g., nurturing and caring, environmental enrichment), and therapeutic interventions influence psychological processes (executive control, behavioral flexibility, reinforcement learning and approach motivation, emotional expression and regulation, self-representation and theory of mind). These psychological processes influence brain networks (attention, motivational, emotional regulation, social cognition), which influence cognitive, social, emotional, identity, and vocational development.

Challenges and prospects in advancing clinical neuropsychology.

In the ever-evolving field of clinical neuropsychology, significant methodological and conceptual limitations hinder progress. To ensure the continued relevance of this discipline amidst remarkable advancements in neuroscience, medicine, and methodology, these obstacles must be addressed. This opinion article identifies inherent limitations within current clinical neuropsychology, including issues such as multi-collinearity in neuropsychological assessments, lack of validated tools reflecting contemporary cognitive function models, and the use of divergent theoretical frameworks in evaluations, leading to a gap between theory and practice. The disconnect between behavior and biomarkers, particularly evident in neurodegenerative diseases but also relevant for other pathologies, together with the rise of genetic analyses, necessitate change. Methodological improvements are crucial for ensuring the discipline's future relevance. Looking ahead, key perspectives and challenges are outlined, emphasizing the need for a holistic approach to cognitive functioning and congruent tools, patient engagement in experimental studies, rectification of biases, and exploration of variables like personality. Training professionals to bridge the gap between practice and research is essential. By addressing these challenges, clinical neuropsychology can not only adapt to the evolving landscape but also shape it, ensuring a brighter future for the field.

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.

[Neuropsychiatry as practised in a highly specialised department of a psychiatric teaching hospital: a successful interdisciplinary approach]. / Topklinische neuropsychiatrie: een succesvolle interdisciplinaire benadering.

BACKGROUND: Psychiatric disorders can be interpreted as a general dysregulation of the interplay between brain and behaviour. This is why, since the late 1990’s, the terms biological psychiatry and behavioural neurology have been gradually replaced by the term neuropsychiatry. Neuropsychiatry, when practiced in combination with clinical neuropsychology, have given rise to a paradigm that is not based solely on the usual classification models but is directed primarily towards diagnosis and treatment that are based on a functional-dimensional approach. AIM: To discuss the daily practice and organisation in a specialised department for neuro-psychiatry located in a psychiatric teaching hospital. METHOD: The interdisciplinary approach is explained and analysed on the basis of 10 case studies. RESULTS: Most of the patients referred to the specialised department already had a long history of visits to the health care facilities where they had been treated by a variety of specialists in single disciplines. Often, however, this trajectory did not involve periodical re-evaluation and updating of the original diagnosis. If this strategy had been adopted, then a clear diagnosis with simplified treatment programme might have been devised which could have resulted in a patient’s successful reintegration into society. CONCLUSION: It is essential that the interdisciplinary approach is adopted in specialised centres for neuropsychiatry because it can make an important contribution to individual patient care and to the spread of specialised knowledge that can benefit the entire field of psychiatry.

Future directions in the neuropsychology of epilepsy.

Two important themes for future clinical research in the neuropsychology of epilepsy are proposed: (1) the neurobiological abnormalities that underlie neuropsychological impairment in people with epilepsy, and (2) neuropsychological status of persons with new-onset epilepsy.

The global pandemic has permanently changed the state of practice for pre-DBS neuropsychological evaluations.

The evaluation and management of patients with movement disorders has evolved considerably due to the COVID-19 pandemic, including the assessment of candidates for deep brain stimulation (DBS) therapy. Members of the Neuropsychology Focus Group from the Parkinson Study Group Functional Neurosurgical Working Group met virtually to discuss current practices and solutions, build consensus, and to inform the DBS team and community regarding the complexities of performing DBS neuropsychological evaluations during COVID-19. It is our viewpoint that the practice of neuropsychology has adapted successfully to provide tele-neuropsychological pre-DBS evaluations during the global pandemic, thus permanently changing the landscape of neuropsychological services.

Central auditory disorders: toward a neuropsychology of auditory objects.

PURPOSE OF REVIEW: Analysis of the auditory environment, source identification and vocal communication all require efficient brain mechanisms for disambiguating, representing and understanding complex natural sounds as 'auditory objects'. Failure of these mechanisms leads to a diverse spectrum of clinical deficits. Here we review current evidence concerning the phenomenology, mechanisms and brain substrates of auditory agnosias and related disorders of auditory object processing. RECENT FINDINGS: Analysis of lesions causing auditory object deficits has revealed certain broad anatomical correlations: deficient parsing of the auditory scene is associated with lesions involving the parieto-temporal junction, while selective disorders of sound recognition occur with more anterior temporal lobe or extra-temporal damage. Distributed neural networks have been increasingly implicated in the pathogenesis of such disorders as developmental dyslexia, congenital amusia and tinnitus. Auditory category deficits may arise from defective interaction of spectrotemporal encoding and executive and mnestic processes. Dedicated brain mechanisms are likely to process specialized sound objects such as voices and melodies. SUMMARY: Emerging empirical evidence suggests a clinically relevant, hierarchical and modular neuropsychological model of auditory object processing that provides a framework for understanding auditory agnosias and makes specific predictions to direct future work.
