Factors contributing to parent-child interaction quality following mild traumatic brain injury in early childhood.

J Neuropsychol 2019 Feb 19. Epub 2019 Feb 19.

Ste-Justine Research Center, Montreal, Quebec, Canada.

There is emerging evidence that parent-child interactions are affected by early childhood traumatic brain injury (TBI). These findings are of functional importance when considering the high prevalence of TBI in early childhood alongside evidence that young children exposed to positive relationships with their parents early in life exhibit better social functioning concurrently and longitudinally. Given that the overall quality of parent-child interactions is the result of both parent and child emotional and behavioural dispositions, it remains unclear which parental or child-related factors contribute to the quality of interactions post-TBI.

Beyond episodic memory: Semantic processing as independent predictor of hippocampal/perirhinal volume in aging and mild cognitive impairment due to Alzheimer's disease.

Neuropsychology 2019 Feb 18. Epub 2019 Feb 18.

Department of Neuroscience, University of Sheffield.

Objective: Given that lexical-semantic decline precedes episodic memory deficits in the Alzheimer's disease (AD) timeline, it is expected that performance on a lexical-semantic task would be associated with mediotemporal volumes independently of the association this region has with episodic memory in the early stage of AD.

Method: Fifty patients with mild cognitive impairment due to AD and 50 healthy adults completed tests of lexical-semantic skills (category fluency test), episodic memory for semantically relevant material (prose memory test), episodic memory for non semantically relevant material (Rey-Osterrieth Figure test), lexical-executive abilities (letter fluency test), and a neurostructural MRI. Hippocampal, perirhinal, entorhinal, temporopolar, and orbitofrontal volumes were extracted. Read More

Sex, dopamine, and hypokinesia: A study of inflectional morphology in Parkinson's disease.

Neuropsychology 2019 Feb 18. Epub 2019 Feb 18.

Brain and Language Laboratory.

Objective: Parkinson's disease (PD), which involves the degeneration of dopaminergic basal ganglia neurons, appears to affect language. We investigated which aspects of language are impaired in PD and what moderates these impairments. Our predictions were based on the declarative/procedural model of language, which links grammar, including in regular inflection, to procedural memory and left-lateralized basal ganglia dopaminergic circuits but links lexical memory, including irregulars, to declarative memory.

Plasticity versus chronicity: Stable performance on category fluency 40 years post-onset.

J Neuropsychol 2019 Feb 15. Epub 2019 Feb 15.

Department of Psychology, Durham University, UK.

What is the long-term trajectory of semantic memory deficits in patients who have suffered structural brain damage? Memory is, per definition, a changing faculty. The traditional view is that after an initial recovery period, the mature human brain has little capacity to repair or reorganize. More recently, it has been suggested that the central nervous system may be more plastic with the ability to change in neural structure, connectivity, and function. Read More

Topological map of the body in post-stroke patients: Lesional and hodological aspects.

Neuropsychology 2019 Feb 7. Epub 2019 Feb 7.

Department of Psychology.

Objective: It has been repeatedly hypothesized that at least 3 distinct types of body representations do exist: , a representation derived from multiple sensory and motor inputs; , a structural description of spatial relations among the body parts; and , a lexical-semantic representation. Although several studies have assessed neural correlates of the topological map of the body in healthy participants, a systematic investigation of neural underpinnings of the topological map of the body in brain-damaged patients is still lacking.

Method: Here we investigated the neural substrates of topological map of the body in 23 brain-damaged patients, both from a topological and an hodological perspectives, using Voxel Lesion Symptom Mapping and atlas-based track-wise statistical analysis. Read More

Effects of APOE on cognitive aging in community-dwelling older adults.

Neuropsychology 2019 Feb 7. Epub 2019 Feb 7.

Department of Family Medicine and Public Health.

Objective: The apolipoprotein E (APOE) gene is an established risk factor for sporadic Alzheimer's disease, with elevated risk for ε4-carriers and reduced risk for ε2-carriers. However, it is unclear whether APOE modifies risk for cognitive decline in normal aging. The objective of this study was to determine whether ε2 and ε4 are associated with rates of normal cognitive aging, and whether associations of ε4 with cognitive decline are modified by sex, education or health behaviors (exercise, alcohol consumption, smoking).

Fear-specific enhancement of tactile perception is disrupted after amygdala lesion.

J Neuropsychol 2019 Feb 4. Epub 2019 Feb 4.

Center for Studies and Research in Cognitive Neuroscience, University of Bologna, Italy.

Tactile perception on one's own face is enhanced when viewing a fearful face being touched - as opposed to just approached - by fingers, compared to viewing other expressions, a phenomenon known as the emotional modulation of Visual Remapping of Touch (eVRT). This effect seems to be related to a preferential activation of the somatosensory system in response to threat. To test the contribution of the amygdala to this mechanism, a group of patients with unilateral lesions to the amygdala, a control group of patients with lesions in the extra-temporal regions, and a group of healthy participants completed an eVRT paradigm.

Cognitive reserve and neuropsychological performance in multiple sclerosis: A meta-analysis.

Neuropsychology 2019 Jan 31. Epub 2019 Jan 31.

Department of Psychology, University of Campania "Luigi Vanvitelli".

Objective: Cognitive dysfunction is frequent in multiple sclerosis (MS), and its relationship with cognitive reserve (CR) has been investigated in several studies with conflicting results. In this meta-analysis, we here sought to determine the relationship between CR and cognition in MS patients and to ascertain whether demographic or clinical variables could moderate the above-mentioned relationship.

Method: We searched three electronic databases for studies assessing the relationship between CR and performance in 6 cognitive domains or processes (verbal and spatial memory, attention, processing speed, verbal fluency, inhibitory control). Read More

HIV and age underlie specific patterns of brain abnormalities and cognitive changes in high functioning patients.

Neuropsychology 2019 Jan 28. Epub 2019 Jan 28.

The Faculty of Psychology, University of Warsaw.

Objective: Findings on the influence of age and HIV on brain and cognition remain equivocal, particularly in aviremic subjects without other age or HIV-related comorbidities. We aimed to (a) examine the effect of HIV status and age on structural brain measurements and cognition, and (b) apply the machine learning technique to identify brain morphometric and cognitive features that are most discriminative between aviremic subjects with HIV on stable combination antiretroviral therapy (cART) and healthy controls.

Method: Fifty-three HIV-seropositive patients and 62 healthy controls underwent neuropsychological testing (executive functions, attention, memory, learning, psychomotor speed, fluency) and volumetric MRI scans. Read More

Attentional shifting and disengagement in Rett syndrome.

Neuropsychology 2019 Jan 28. Epub 2019 Jan 28.

Rett Syndrome Center, Department of Neurology, Children's Hospital at Montefiore.

Objective: The purpose of the present study was to deepen our understanding of attention (a core cognitive ability) in Rett syndrome (RTT), an x-linked neurodevelopmental disorder caused by mutations in the MECP2 gene. We focused on 2 key aspects of visual orienting-shifting and disengaging attention-both of which are critical for exploring the visual world. We used gaze-based measures and eye-tracking technology to minimize demands on the limited verbal and motor abilities associated with RTT. Read More

Awareness of consequences in agenesis of the corpus callosum: Semantic analysis of responses.

Neuropsychology 2019 Feb 21;33(2):275-284. Epub 2019 Jan 21.

Graduate School of Psychology, Travis Research Institute, Fuller Theological Seminary.

Objective: Agenesis of the corpus callosum (AgCC) in individuals with general intelligence within the normal range results in a syndrome of mild to moderate deficiencies in cognitive, emotional, and social functioning that are still being explored. Anecdotal accounts from families suggest that these cognitive and psychosocial deficiencies affect the ability of these individuals to anticipate the consequences of their decisions and behaviors. This research was designed to clarify the nature of social and emotional cognition in AgCC with respect to imagination of the consequences of decisions by assessing responses from the Awareness of Consequences Scale (AOCS).

Anodal tDCS over Wernicke's area improves verbal memory and prevents the interference effect during words learning.

Neuropsychology 2019 Feb 21;33(2):263-274. Epub 2019 Jan 21.

Department of Psychology, University of Huelva.

Background: Wernicke's area is a key component of the cortical language network, and it is functionally related to the comprehension of oral and written language. In addition to its main role in the perception of language, some other functions related to verbal learning also seem to involve the activity of this cortical region. It is unknown whether different degrees of neuromodulation on this area determine its effect on word learning. Read More

Episodic foresight and stroke.

Neuropsychology 2019 Jan;33(1):93-102

School of Psychology, University of Queensland.

Objective: Stroke is often associated with increased difficulty engaging in specific future-directed thoughts and behaviors, such as generating phenomenological characteristics of future events (a component of episodic foresight) and executing directed preparatory behaviors (a component of prospective memory). The objective of this study was to clarify whether this group also exhibits increased difficulties using episodic foresight to appropriately guide future-directed behaviors.

Method: Stroke patients (n = 26) and demographically matched healthy controls (n = 26) were administered a behavioral measure that met strict criteria for assessing episodic foresight. Read More

Spatial asymmetries undermine also the short forms of the Judgement of Line Orientation test.

Neuropsychology 2018 Dec 27. Epub 2018 Dec 27.

Dipartimento di Psicologia e Scienze Cognitive, University of Trento.

Objective: The Judgment of Line Orientation (JLO) test is one of the most used tasks for the assessment of visuospatial perception. However, JLO items show a left-right structural asymmetry that interacts with the ipsilesional attentional biases of brain-damaged patients, that is, the main target population for which the test is intended, and undermines the test's validity. Left hemisphere-damaged patients are favored by the way the stimulus lines are distributed in the original items, whereas right hemisphere-damaged patients are favored by the opposite distribution, obtained by mirror reversing the items (Treccani, Torri, & Cubelli, 2005).

Executive function, impulsivity, and risky behaviors in young adults.

Neuropsychology 2019 Feb 27;33(2):212-221. Epub 2018 Dec 27.

Department of Psychology and Counseling.

Objective: Among patients with brain damage, executive function deficits and impulsivity correspond with propensity to engage in risky behaviors. Less research has addressed this issue in healthy adults, and fewer still have simultaneously evaluated the importance of executive function and impulsive personality. Additionally, most research has focused exclusively on substance use while ignoring other domains of risky behavior such as sexual activity and antisocial practices. Read More

We see the orange not the lemon: typicality effects in ultra-rapid categorization in adults with and without autism spectrum disorder.

J Neuropsychol 2018 Dec 4. Epub 2018 Dec 4.

NOVA Medical School, Faculdade de Ciências Médicas, Universidade Nova de Lisboa, Portugal.

Semantic meaning can be extracted from pictures presented very briefly, in the order of tens of milliseconds. This ultra-rapid categorization processing appears to respect a coarse-to-fine path where lower level representations of concepts, or more detailed information, need additional time. We question whether variations in the levels of typicality of the target-item would implicate additional processing for correct classification, both in neurotypical (NT) individuals and with autism spectrum disorder (ASD).

Semantic network function captured by word frequency in nondemented APOE ε4 carriers.

Neuropsychology 2019 Feb 29;33(2):256-262. Epub 2018 Nov 29.

Taub Institute for Research on Alzheimer's Disease and the Aging Brain.

Objective: Accurate identification of the earliest cognitive changes associated with Alzheimer's disease (AD) is critically needed. Item-level information within tests of category fluency, such as lexical frequency, harbors valuable information about the integrity of semantic networks affected early in AD. To determine the potential of lexical frequency as a cognitive marker of AD risk, we investigated whether lexical frequency of animal fluency output differentiated ε4 carriers from noncarriers in a cross-sectional design among older African-American adults without dementia.

Lesion symptom mapping at the regional level in patients with a meningioma.

Neuropsychology 2019 Jan 26;33(1):103-110. Epub 2018 Nov 26.

Department of Cognitive Neuropsychology, Tilburg University.

Objective: The majority of meningioma patients suffer from presurgical cognitive deficits. Since meningiomas do not directly damage the brain, this is presumably caused by a functional integrity reduction of the surrounding brain tissue through perilesional edema and/or mass effect of the tumor. Tumor location is a key feature in determining neurological symptoms in brain tumor patients, but the relationship between meningioma location and cognitive performance remains unclear. Read More

Information processing deficit in older adults with HIV infection: A comparison with Parkinson's disease.

Neuropsychology 2019 Feb 26;33(2):157-168. Epub 2018 Nov 26.

Neuroscience Program, Center for Health Sciences, Bioscience Division, SRI International.

Objective: Individuals with HIV treated with antiretroviral therapy can expect to reach average life span, making them susceptible to combined disease and aging effects on cognitive and motor functions. Slowed processing speed in HIV is a concern for cognitive and everyday functioning and is sensitive to declines in aging. We hypothesized that information processing (IP) deficits, over and above that expected with normal aging, would occur in older HIV patients similar to those observed in Parkinson's disease (PD) patients, with both conditions affecting frontostriatal pathways.

The role of hippocampus in the retrieval of autobiographical memories in patients with amnestic Mild Cognitive Impairment due to Alzheimer's disease.

J Neuropsychol 2018 Nov 19. Epub 2018 Nov 19.

Department of Clinical and Behavioural Neurology, Santa Lucia Foundation, IRCCS, Rome, Italy.

The role of the hippocampus and neocortical areas in the retrieval of past memories in pre-dementia Alzheimer's disease (AD) patients was investigated. The aim was to assess whether the hippocampus has a temporary role in memory trace formation, according to the Cortical Reallocation Theory (CRT), or whether it continuously updates and enriches memories, according to the Multiple Trace Theory. According to the former theory, hippocampal damage should affect more recent memories, whereas the association cortex is expected to affect memories of the entire lifespan. Read More

Salience network connectivity and social processing in children with nonverbal learning disability or autism spectrum disorder.

Neuropsychology 2019 Jan 8;33(1):135-143. Epub 2018 Nov 8.

Division of Child and Adolescent Psychiatry, Department of Psychiatry, Columbia University Irving Medical Center.

Objective: Nonverbal learning disability (NVLD) is a putative neurodevelopmental disorder characterized by spatial processing deficits as well as social deficits similar to those characteristic of autism spectrum disorder (ASD). Nonetheless, NVLD may be a distinct disorder that is differentially associated with the functioning and connectivity of the salience (SN) and default mode (DMN) networks that support social processing. Thus, we sought to assess and compare connectivity across these networks in children with NVLD, ASD, and typically developing children. Read More

The effects of integrated single- and dual-task training on automaticity and attention allocation in Parkinson's disease: A secondary analysis from a randomized trial.

Neuropsychology 2019 Feb 8;33(2):147-156. Epub 2018 Nov 8.

Department of Neurobiology, Care Sciences and Society, Division of Physiotherapy, Karolinska Institutet.

Objective: People with Parkinson's disease (PwPD) demonstrate impaired automaticity of motor and cognitive tasks, with unclear prioritization strategies when exposed to dual-task situations. However, no randomized trials have investigated the effects of training on automaticity and prioritization strategies in this population. The purpose of this study was to investigate the effects of training on the automaticity of gait and cognitive processing in PwPD and the allocation of attention between gait and a cognitive task.

Differences in visuospatial processing in individuals with nonverbal learning disability or autism spectrum disorder without intellectual disability.

Neuropsychology 2019 Jan 18;33(1):123-134. Epub 2018 Oct 18.

Child Neuropsychiatry Unit.

Objective: Although previous reports produced converging empirical evidence of a core deficit on visuospatial processing in children with a nonverbal learning disability (NLD), few studies compared the visuospatial profile of individuals with an autism spectrum disorder (ASD) or NLD in visuoconstructive and visuospatial working memory tasks. Nor did any of these studies investigate the role of the local bias, typically observed in ASD, when comparing these clinical groups. The present study aimed to analyze whether NLD and ASD share any characteristics. Read More

Worse cognitive performance predicts increased anxiety and depressive symptoms in patients with Parkinson's disease: A bidirectional analysis.

Neuropsychology 2019 Jan 18;33(1):35-46. Epub 2018 Oct 18.

Department of Neurology, University of Southern California.

Objective: Symptoms of anxiety, depression commonly co-occur with cognitive decline in patients with Parkinson's disease (PD). The directionality of this association is unclear, however, in that poor cognitive performance may lead to increased symptoms of anxiety and depression or higher anxiety and depressive symptoms may lead to cognitive decline. The purpose of this study was to elucidate the directionality of the association between symptoms of anxiety and depression with cognitive performance in newly diagnosed patients with PD. Read More

Simulated driving: The added value of dynamic testing in the assessment of visuo-spatial neglect after stroke.

J Neuropsychol 2018 Oct 16. Epub 2018 Oct 16.

Center of Excellence for Rehabilitation Medicine, Brain Center Rudolf Magnus, University Medical Center Utrecht, Utrecht University and De Hoogstraat Rehabilitation, The Netherlands.

Background: Visuo-spatial neglect (VSN) is generally assessed with neuropsychological paper-and-pencil tasks, which are often not sensitive enough to detect mild and/or well-compensated VSN. It is of utmost importance to develop dynamic tasks, resembling the dynamics of daily living.

Objective: A simulated driving task was used to assess (1) differences in performance (i. Read More

The ipsilesional attention bias in right-hemisphere stroke patients as revealed by a realistic visual search task: Neuroanatomical correlates and functional relevance.

Neuropsychology 2018 Oct;32(7):850-865

Department of Neurology, University of Lübeck.

Objective: Right-hemisphere stroke may cause an ipsilesional attention bias and left hemispatial neglect. Computerized time-limited tasks are more sensitive than conventional paper-pencil tests in detecting these spatial attention deficits. However, their frequency in the acute stage of stroke, the neuroanatomical basis and functional relevance for patients' everyday life are unclear. Read More

Developmental differentiation of executive functions on the NIH Toolbox Cognition Battery.

Neuropsychology 2018 Oct;32(7):777-783

Department of Radiology, University of California, San Diego.

Objective: The NIH Toolbox Cognition Battery (NTCB) is a brief computerized method for evaluating neuropsychological functions in children, adolescents, and adults. We examined how performance on the 2 executive function measures of cognitive flexibility and inhibitory control was related to performance on the other NTCB measures across development.

Method: Participants were 1,020 typically developing individuals between the ages of 3 and 21 from the Pediatric Imaging, Neurocognition, and Genetics Study who were divided into 5 age groups (3-6, 7-9, 10-13, 14-17, and 18-21). Read More

Assessment of cognitive-driven activity of daily living impairment in non-demented Parkinson's patients.

J Neuropsychol 2018 Oct 15. Epub 2018 Oct 15.

Department of Neurodegenerative Diseases, Hertie Institute for Clinical Brain Research, University of Tübingen, Germany.

The core criterion for Parkinson's disease dementia (PDD) is the impairment in activities of daily living (ADL) function primarily caused by cognitive, not motor symptoms. There is evidence to assume that mild ADL impairments in mild cognitive impairment (PD-MCI) characterize those patients at high risk for dementia. Data of 216 Parkinson's disease (PD) patients assessed with comprehensive motor and neuropsychological assessments were analysed. Read More

Modelling picture naming in aphasia: The relationship between consistency and predictability of responses.

Neuropsychology 2019 Jan 4;33(1):60-76. Epub 2018 Oct 4.

Centro Interdipartimentale Mente/Cervello.

Objective: Two aspects of aphasic picture naming were examined: that is, the extent to which the accuracy of the response to the same stimulus is replicated in a successive examination, and , that is, the extent to which accuracy depends on the characteristics of each stimulus.

Methods: Thirty-eight aphasic participants were examined twice. The response pattern was the same across the 2 presentations (response stability) for 36 participants, who were classified into 3 groups according to the prevailing error-type (lexical-semantic, phonological, or a balance between the two error-types): Their item-consistency was quantified with Cohen's kappa.

The relationship between response consistency in picture naming and storage impairment in people with semantic variant primary progressive aphasia.

Neuropsychology 2019 Jan 4;33(1):13-34. Epub 2018 Oct 4.

ARC Centre of Excellence in Cognition and its Disorders.

Objective: The progressive loss of stored knowledge about word meanings in semantic variant primary progressive aphasia (svPPA) has been attributed to an amodal "storage" deficit of the semantic system. Performance consistency has been proposed to be a key characteristic of storage deficits but has not been examined in close detail and larger participant cohorts.

Method: We assessed whether 10 people with svPPA showed consistency in picture naming across 3 closely consecutive sessions. Read More

Executive impairment is associated with unawareness of neuropsychiatric symptoms in premanifest and early Huntington's disease.

Neuropsychology 2018 Nov 13;32(8):958-965. Epub 2018 Sep 13.

Monash Institute of Cognitive and Clinical Neurosciences, School of Psychological Sciences, Monash University.

Objective: Unawareness of neuropsychiatric symptoms appears to be common in Huntington's disease (HD), but the clinical correlates of unawareness are unclear. Identifying predictors of unawareness is important for improving diagnosis of neuropsychiatric symptoms, and cognitive impairment, specifically executive impairment, may be a potential important predictor of unawareness. The authors examined whether unawareness of neuropsychiatric symptoms is more common in early HD compared to premanifest HD, and whether executive task performance was associated with awareness, independent of demographic, motor or mood variables.

Hearing loss and verbal memory assessment among older adults.

Neuropsychology 2019 Jan 13;33(1):47-59. Epub 2018 Sep 13.

Department of Otolaryngology-Head and Neck Surgery.

Objective: Research has found that adults with hearing loss perform worse on cognitive testing than adults without hearing loss; however, heavy emphasis on tests involving auditory stimuli may overdiagnose cognitive impairment among individuals with hearing loss. This study compared visual- and auditory-verbal memory tests among adults with and without hearing loss.

Method: Forty-one adults with hearing loss (HL) and 41 age-matched adults with normal hearing (NH) completed a neuropsychological battery that included auditory and visual versions of the Hopkins Verbal Learning Testing-Revised (HVLT-R). Read More

Intraindividual variability in neuropsychological performance predicts cognitive decline and death in HIV.

Neuropsychology 2018 Nov 13;32(8):966-972. Epub 2018 Sep 13.

Department of Psychiatry and Biobehavioral Sciences, University of California, Los Angeles, Geffen School of Medicine.

Objective: HIV-associated neurocognitive disorder (HAND) occurs in a significant percentage of HIV-infected (HIV+) adults. Increased intraindividual variability (IIV) in cognitive function may be an early marker of emerging neurocognitive disorder, which suggests that IIV may be a sensitive measure of neurologic compromise in HIV. In the current study, we hypothesize that increased IIV may predict impending morbidity, including future cognitive decline and death. Read More
