Do children with attention-deficit/hyperactivity disorder (ADHD) have set shifting deficits?

Neuropsychology 2019 Apr 4. Epub 2019 Apr 4.

Department of Psychology, Florida State University.

Objective: Set shifting, or cognitive flexibility, is a core executive function involving the ability to quickly and efficiently shift back and forth between mental sets. Meta-analysis suggests medium-magnitude shifting impairments in attention-deficit/hyperactivity disorder (ADHD). However, this conclusion may be premature because the evidence-base relies exclusively on tasks that have been criticized for poor construct validity and may better reflect general neuropsychological functioning rather than shifting specifically.

A culturally fair test of processing speed: Construct validity, preliminary normative data, and effects of HIV infection on performance in South African adults.

Neuropsychology 2019 Mar 14. Epub 2019 Mar 14.

ACSENT Laboratory.

Objectives: Impaired processing speed (PS) is a feature of cognitive profiles associated with neurological disorders particularly prevalent in low- or middle-income countries (LMICs). However, commonly used PS tests are not validated for use in LMICs. We assessed, using a sample of healthy South African adults, the construct validity of PS tests contained within NeuroScreen (a tablet-based application and test battery designed to be culturally fair), and established preliminary normative data for those tests (Study 1).

Adolescent cannabis use and its associations with decision-making and episodic memory: Preliminary results from a longitudinal study.

Neuropsychology 2019 Mar 14. Epub 2019 Mar 14.

Center for Children and Families, Department of Psychology, Florida International University.

Objective: Impairments in neurocognitive functioning, including memory and executive functions, have been identified among adult cannabis users; however, less is known about the effects of cannabis use (CU) among adolescent users. Delineating the directionality of associations between CU and neurocognition has been restricted due to the relatively few longitudinal studies examining this question. As such, we examined whether decision-making prospectively predicted CU, and whether increases in CU were associated with changes in decision-making and episodic memory among a sample consisting predominantly of adolescent cannabis users.

Motion-induced position mis-localization predicts the severity of Alzheimer's disease.

J Neuropsychol 2019 Mar 12. Epub 2019 Mar 12.

Department of Neurology, Liaocheng People's Hospital, China.

Patients with Alzheimer's disease (AD) often exhibit motion processing deficits. It is unclear whether the localization of moving objects - a perceptual process tightly linked to motion - is impaired or intact in AD. In this study, we used the phenomenon of illusory shift of position induced by motion as a behavioural paradigm to probe how the spatial representation differs between AD patients and healthy elderly controls.

Robust norms for neuropsychological tests of verbal episodic memory in Australian women.

Neuropsychology 2019 Mar 4. Epub 2019 Mar 4.

Department of Medicine (Royal Melbourne Hospital).

Objective: Robust norms for neuropsychological tests may offer superior clinical utility to conventional norms, in their ability to distinguish normal cognitive aging from prodromal dementia. However, the availability of robust norms from midlife, where cognitive changes in those at risk of disease may arise, is limited. This study presents demographically stratified robust norms for tests of verbal memory in Australian women. Read More

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 Mar 7;33(3):406-416. 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.

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).

Neuropsychology 2019 Feb 21;33(2):178-194. Epub 2019 Jan 21.

University of Geneva.

Objective: Deep brain stimulation (DBS) has become a well-established treatment that significantly improves the motor symptoms of Parkinson's disease (PD). Patients may nevertheless experience psychosocial maladjustment after surgery, as reported by an increasing body of research. Yet, no comprehensive theoretical approach has been proposed to account for this. Read More

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 2019 Mar 27;33(3):301-308. 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.

The influence of aerobic fitness on top-down and bottom-up mechanisms of interference control.

Neuropsychology 2019 Feb 29;33(2):245-255. Epub 2018 Nov 29.

Institute of Physical Education, Health and Leisure Studies.

Objective: Extensive evidence has demonstrated the relationship between aerobic fitness and cognitive function in early adulthood. Little is known, however, about whether the cognitive benefits of aerobic fitness are related to the modulation of top-down or bottom-up mechanisms in the control of executive attention. The present study aimed to shed light on this question by evaluating the phase-locking factor (PLF) of electroencephalogram (EEG) signal during cognitive control. Read More

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

Contributions of olfactory and neuropsychological assessment to the diagnosis of first-episode schizophrenia.

Neuropsychology 2019 Feb 26;33(2):203-211. Epub 2018 Nov 26.

Department of Psychiatry and Behavioral Sciences.

Objective: First-episode schizophrenia and schizoaffective patients (SZ+) show olfactory impairments, but how these relate to cognitive dysfunction remains unclear. We examined the relationship between cognitive and olfactory dysfunction in SZ+ and the clinical utility of these measures in the assessment of SZ+ patients.

Method: First-episode SZ+ patients (n = 63) and controls (n = 63) were administered tests of odor identification and discrimination in addition to measures of manual dexterity, processing speed, attention and working memory, executive functioning, ideational fluency, and memory. 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.
