Implementation of a Hybrid Teleneuropsychology Method to Assess Middle Aged and Older Adults During the COVID-19 Pandemic.

ObjectiveHybrid teleneuropsychology has emerged as a useful assessment method to manage physical distancing requirements during the COVID-19 pandemic. We describe the development of a hybrid teleneuropsychology clinic and compare results of six neuropsychological tasks across testing modalities, as well as a participant experience survey.MethodHealthy middle-aged and older adults completed a face-to-face assessment two years previously. Participants either completed reassessment face-to-face or via the hybrid setup. Results were compared across time points and delivery modality.ResultsThere were no significant differences in scores at reassessment between face-to-face and a hybrid setup on nonverbal fluid intelligence, verbal memory, visual memory, language, working memory or verbal initiation. Retest reliability was moderate to excellent for verbal and visual memory, attention and naming. Results of an anonymous survey indicated that participants felt comfortable and established good rapport with the examiner.ConclusionsThis hybrid method of teleneuropsychology can be used to obtain high quality and reliable results including on tasks yet to be evaluated for teleneuropsychology, including the Graded Naming Test and the Topographical Recognition Memory Test.

Joint Attention Ability and the Neurocognitive functioning in children with Autism Spectrum Disorders

Introduction: Autism spectrum disorders (ASD) have neurobiological origins but the exact nature of these brain dysfunctions has not been yet fully elucidated. Children with autism have difficulties in processing social and emotional stimuli, imitating body movements or interpreting relational gestures. These difficulties suggest as candidate factors related to autistic symptomatology, a specialised brain system involved in the mechanisms of social cognition, consisting in the medial temporal lobe (MTL) and the ventromedial prefrontal cortex (VMPFC). Objective: Our research examines whether young children with autism are impaired on neuropsychological tasks and also if the performance on such neurocognitive tasks can be correlated with joint attention ability (JAT). Methods: Three groups of children – with autism, with intellectual disability and with typical development, matched according to the mental age (calculated with the Fairview development scale, Giampiccolo & Boroskin, 1974) were administered neurocognitive and joint attention tests and procedures. Results: The results showed that only the MTL-VMPFC task performances were strongly correlated with the JAT behavior, while the dorsolateral prefrontal (DLPFC) ones were not. Conclusion: Our findings suggest that the VMPFC is involved in the development of JAT mechanisms. We found no correlation between the performance in tasks related to JAT behavior and the DLPFC factor. This means that autism is not associated, at least at young ages, with a unique pattern of poor executive functioning, so this dimension cannot be used as an indicator for the early diagnosis of autism.

Cognitive and Experienced Flexibility in Patients With Anorexia Nervosa and Obsessive Compulsive Disorder.

ObjectiveAnorexia nervosa (AN) and obsessive-compulsive disorder (OCD) share a neuropsychological profile characterized by cognitive inflexibility as evident in set-shifting problems, and by strong detail focus. Clinically, both patient groups display a strong rigidity which may be explained by these neurocognitive difficulties. Cognitive inflexibility may hinder treatment uptake and help explain suboptimal treatment outcomes in both AN and OCD. This is the first study to compare clinical AN and OCD groups andto examine similarities and differences in cognitive flexibility. Specifically, this study aims to investigate neuropsychological outcomes and self-reported difficulties in both clinical groups and a control group, and explore associations between the different flexibility outcomes and illness.MethodTwo hundred participants (61 AN, 72 OCD and 67 HC) performed neuropsychological tasks on set-shifting abilities (Trail Making Task, Stroop color-word interference, Intradimensional-Extradimensional shift task), detail focus (Group Embedded Figures Test) and self-reported set-shifting abilities and attention to detail (DFlex).ResultsSimilarities between patient groups were found in terms of reduced set-shifting ability on the Trail Making Task and detail focus. Moreover, both patient groups self-reported more set-shifting problems but a less strong detail focus than HC, which in turn were not related to neuropsychological task outcomes in either of the groups. In both patient groups longer illness duration was associated to longer reaction times in the switching tasks and for both groups symptom severity was associated to higher experienced inflexibility and attention to detail.ConclusionCognitive inflexibility processes are largely similar in patients with AN and OCD. Both patient groups report inflexibility, yet this is unrelated to neuropsychological outcomes. Illness duration seems to contribute to poorer set-shifting and higher illness severity is linked to more experienced inflexibility. Findings highlight the need for entangling different domains of cognitive flexibility and detail focus and examining self-report measures for a cohesive understanding of clinically relevant flexibility weaknesses in AN and OCD.

Post-stroke apathy: A case series investigation of neuropsychological and lesion characteristics

Apathy is a multi-dimensional syndrome associated with reduced initiation, executive function and emotion toward goal-directed behaviour. Affecting ∼30% of stroke patients, apathy can negatively impact rehabilitation outcomes and increase caregiver burden. However, relatively little is known about the multi-dimensional nature of post-stroke apathy and whether these dimensions map onto neuropsychological and neuroanatomical correlates. The present study aimed to address this question in a case series of stroke patients with apathy. 65 patients with acute stroke were assessed on a comprehensive battery of neuropsychological tasks and 12 patients were identified as having clinically significant apathy on one or more domains on the Dimensional Apathy Scale. Individual scores were compared to a group of healthy controls and normative data where available. Lesion mapping was completed from clinical CT and MRI scans to characterise the extent and locations of each patient's lesion. All participants performed significantly poorer than controls on one or more tasks. Difficulties with inhibition were observed across all dimensions. Prospective memory deficits were also common, while speed and social cognition were only reduced in initiation and emotional apathy, respectively. Verbal fluency was not impaired in any of the patients, despite previously established relationships with apathy. Lesions were predominantly located in right subcortical regions, with some additional frontal, temporal and cerebellar/brainstem involvement. There was substantial overlap in lesion locations within and between dimensions, such that similar apathy symptoms occurred in patients with very different lesion sites. Overall, our results suggest that neuropsychological and lesion profiles of apathy in stroke patients may be more complex and heterogenous than in neurodegenerative disease, possibly due to functional changes occurring beyond the lesion site.

Differentiating Individuals with and without Alcohol Use Disorder Using Resting-State fMRI Functional Connectivity of Reward Network, Neuropsychological Performance, and Impulsivity Measures.

Individuals with alcohol use disorder (AUD) may manifest an array of neural and behavioral abnormalities, including altered brain networks, impaired neurocognitive functioning, and heightened impulsivity. Using multidomain measures, the current study aimed to identify specific features that can differentiate individuals with AUD from healthy controls (CTL), utilizing a random forests (RF) classification model. Features included fMRI-based resting-state functional connectivity (rsFC) across the reward network, neuropsychological task performance, and behavioral impulsivity scores, collected from thirty abstinent adult males with prior history of AUD and thirty CTL individuals without a history of AUD. It was found that the RF model achieved a classification accuracy of 86.67% (AUC = 93%) and identified key features of FC and impulsivity that significantly contributed to classifying AUD from CTL individuals. Impulsivity scores were the topmost predictors, followed by twelve rsFC features involving seventeen key reward regions in the brain, such as the ventral tegmental area, nucleus accumbens, anterior insula, anterior cingulate cortex, and other cortical and subcortical structures. Individuals with AUD manifested significant differences in impulsivity and alterations in functional connectivity relative to controls. Specifically, AUD showed heightened impulsivity and hypoconnectivity in nine connections across 13 regions and hyperconnectivity in three connections involving six regions. Relative to controls, visuo-spatial short-term working memory was also found to be impaired in AUD. In conclusion, specific multidomain features of brain connectivity, impulsivity, and neuropsychological performance can be used in a machine learning framework to effectively classify AUD individuals from healthy controls.

Common neuropsychological assessment measures as performance indicators in neuropsychological rehabilitation: An exploratory correlational study

This study aims to identify neuropsychological assessment measures that can better guide the selection and difficulty level adjustment of neuropsychological rehabilitation tasks for patients with acquired brain injury. Eight patients with acquired brain injury were recruited from one rehabilitation institution. The neuropsychological protocol included standard neuropsychological tests targeting attention, memory, and executive functions. After the assessment, the patients enrolled in an intensive online cognitive neuropsychological rehabilitation training program (80 sessions of 49 cognitive training and 31 affective and psychosocial intervention sessions). The association between the assessment results and the training outcomes was measured to explore which measures were better associated with specific training outcomes. This study suggests that the results of specific conventionally administered neuropsychological tests can be good indicators of the patients’ performance in the cognitive training of attention and working memory. On the other hand, none of the tests provided valuable data regarding the patients’ ability to perform the executive functioning training tasks, perhaps because those appeal to everyday situations, which are not adequately represented in the administered tests. More research is needed, especially regarding the executive function.

Validation of the National Institute of Health Toolbox Cognition Battery (NIHTB-CB) in Children and Adolescents with and without HIV Infection in Lusaka, Zambia.

The objective of this study was to validate the NIH Toolbox Cognition Battery (NIHTB-CB) in Zambian children with and without HIV-infection. Children living with HIV and HIV-exposed, uninfected (HEU) children completed traditional neuropsychological and NIHTB-CB tasks. Using pairwise correlation and a linear regression model we measured associations between traditional measure composite scores and parental ratings of children's abilities, and NIHTB-CB scores. A Receiver Operating Characteristic (ROC) curve was developed to identify participants with impairment. 389 children, 8-17 years old participated. NIHTB-CB and traditional measures converged well as a whole and when comparing analogous individual tests across the two batteries. The NIHTB-CB composite score discriminated between the groups and was positively associated with external criteria for cognitive function: parental ratings of intelligence and school performance. Some English vocabulary and/or an unfamiliar cultural context presented challenges. NIHTB-CB was associated with children's everyday cognitive abilities, though future use may require linguistic and cultural adaptation.

Trajectories of Cognitive Decline in Brain Donors With Autopsy-Confirmed Alzheimer Disease and Cerebrovascular Disease.

Cerebrovascular disease (CBVD) is frequently comorbid with autopsy-confirmed Alzheimer disease (AD), but its contribution to the clinical presentation of AD remains unclear. We leveraged the National Alzheimer's Coordinating Center (NACC) uniform and neuropathology datasets to compare the cognitive and functional trajectories of AD+/CBVD+ and AD+/CBVD- brain donors. The sample included NACC brain donors with autopsy-confirmed AD (Braak stage ≥3, Consortium to Establish a Registry for Alzheimer's Disease score ≥2) and complete Uniform Data Set (UDS) evaluations between 2005 and 2019, with the most recent UDS evaluation within 2 years of autopsy. CBVD was defined as moderate to severe arteriosclerosis or atherosclerosis. We used propensity score weighting to isolate the effects of comorbid AD and CBVD. This method improved the balance of covariates between the AD+/CBVD+ and AD+/CBVD- groups. Longitudinal mixed-effects models were assessed with robust bayesian estimation. UDS neuropsychological test and the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) scores were primary outcomes. Of 2,423 brain donors, 1,476 were classified as AD+/CBVD+. Compared with AD+/CVBD- donors, the AD+/CBVD+ group had accelerated decline (i.e., group × time effects) on measures of processing speed (β = -0.93, 95% CI -1.35, -0.51, Bayes factor [BF] 130.75), working memory (β = 0.05, 95% CI 0.02, 0.07, BF 3.59), verbal fluency (β = 0.10, 95% CI 0.04, 0.15, BF 1.28), naming (β = 0.09, 95% CI 0.03, 0.16, BF = 0.69), and CDR-SB (β = -0.08, 95% CI -0.12, -0.05, BF 18.11). Effects ranged from weak (BFs <3.0) to strong (BFs <150). We also found worse performance in the AD+/CBVD+ group across time on naming (β = -1.04, 95% CI -1.83, -0.25, BF 2.52) and verbal fluency (β = -0.73, 95% CI -1.30, -0.15, BF 1.34) and more impaired CDR-SB scores (β = 0.45, 95% CI 0.01, 0.89, BF 0.33). In brain donors with autopsy-confirmed AD, comorbid CBVD was associated with an accelerated functional and cognitive decline, particularly on neuropsychological tests of attention, psychomotor speed, and working memory. CBVD magnified effects of AD neuropathology on semantic-related neuropsychological tasks. Findings support a prominent additive and more subtle synergistic effect for comorbid CBVD neuropathology in AD.

Differences in Learning and Persistency Characterizing Behavior in Chronic Pain for the Iowa Gambling Task: Web-Based Laboratory-in-the-Field Study.

BackgroundChronic pain is a significant worldwide health problem. It has been reported that people with chronic pain experience decision-making impairments, but these findings have been based on conventional laboratory experiments to date. In such experiments, researchers have extensive control of conditions and can more precisely eliminate potential confounds. In contrast, there is much less known regarding how chronic pain affects decision-making captured via laboratory-in-the-field experiments. Although such settings can introduce more experimental uncertainty, collecting data in more ecologically valid contexts can better characterize the real-world impact of chronic pain.ObjectiveWe aim to quantify decision-making differences between individuals with chronic pain and healthy controls in a laboratory-in-the-field environment by taking advantage of internet technologies and social media.MethodsA cross-sectional design with independent groups was used. A convenience sample of 45 participants was recruited through social media: 20 (44%) participants who self-reported living with chronic pain, and 25 (56%) people with no pain or who were living with pain for <6 months acting as controls. All participants completed a self-report questionnaire assessing their pain experiences and a neuropsychological task measuring their decision-making (ie, the Iowa Gambling Task) in their web browser at a time and location of their choice without supervision.ResultsStandard behavioral analysis revealed no differences in learning strategies between the 2 groups, although qualitative differences could be observed in the learning curves. However, computational modeling revealed that individuals with chronic pain were quicker to update their behavior than healthy controls, which reflected their increased learning rate (95% highest–posterior-density interval [HDI] 0.66-0.99) when fitted to the Values-Plus-Perseverance model. This result was further validated and extended on the Outcome-Representation Learning model as higher differences (95% HDI 0.16-0.47) between the reward and punishment learning rates were observed when fitted to this model, indicating that individuals with chronic pain were more sensitive to rewards. It was also found that they were less persistent in their choices during the Iowa Gambling Task compared with controls, a fact reflected by their decreased outcome perseverance (95% HDI −4.38 to −0.21) when fitted using the Outcome-Representation Learning model. Moreover, correlation analysis revealed that the estimated parameters had predictive value for the self-reported pain experiences, suggesting that the altered cognitive parameters could be potential candidates for inclusion in chronic pain assessments.ConclusionsWe found that individuals with chronic pain were more driven by rewards and less consistent when making decisions in our laboratory-in-the-field experiment. In this case study, it was demonstrated that, compared with standard statistical summaries of behavioral performance, computational approaches offered superior ability to resolve, understand, and explain the differences in decision-making behavior in the context of chronic pain outside the laboratory.

Medication management and treatment adherence in Parkinson's disease patients with mild cognitive impairment.

The key feature that distinguishes mild cognitive impairment (MCI) from dementia is the absence of significant functional decline because of cognitive impairment. In Parkinson's disease patients (PD) with MCI (PD-MCI), the effect of cognitive impairment on complex instrumental daily activities, such as medication management, is not well established. 26 patients with PD-MCI (diagnosed to Level 2 Movement Disorders Society diagnostic criteria) and 32 idiopathic PD patients without cognitive impairment participated in the study. A detailed neuropsychological testing battery (including tests for attention and working memory, executive functions, language, visuospatial functions, episodic memory) and various prospective memory tasks were applied to the patients. Medication taking behaviors were evaluated using two different methods based on the performance (medication management ability assessment) and self-reporting (adherence scale). The PD-MCI group obtained significantly lower scores in medication management assessment and made more mistakes on following prescription instructions (e.g., they took more or less tablets and did not use medications as instructed with regard to meal times). Cognitive areas predicting success in medication management performance were language, event-based prospective memory and visuospatial functions. There was no significant difference between the two groups' self-reporting of adherence. Mild cognitive impairment in patients with PD adversely affects medication management. Diagnosing MCI in PD is important to ensure that the appropriate measures can be taken to provide support and improve the medication management process. Adherence assessments based on self-reporting may not provide reliable and sensitive information in patients with PD-MCI.

The Effect of Caffeine and Sleep Quality on Military Pilot Students’ Flight Performance-Related Cognitive Function

ABSTRACT Objective To assess the effect of caffeine and sleep quality on the flight performance-related cognitive function. Background High levels of cognitive performance in pilots is required for flight safety. Methods Students at a military flight school in Thailand were invited to participate in this study. Exclusion criteria was positive screening for caffeine use disorder. We examined three cognitive functions required for flight performance: (1) vigilance (Mackworth Clock Test), (2) situational awareness, including memory (Corsi block-tapping test) and spatial reasoning (mental rotation test), and (3) reaction time (Deary-Liewald task). Neuropsychological tasks were performed before and 30 minutes after drinking a bottle of 220 ml coffee containing 143 mg of caffeine. Sleep quality was measured by the Thai-Pittsburgh Sleep Quality Index. Results Twenty-nine healthy males without caffeine use disorder with a mean age of 25.1 years were enrolled. After low-dose caffeine intake (<3 mg/kg body weight), cognitive performance improved significantly in vigilance, situation awareness, and reaction time. Baseline cognitive performance was not different between high (HSQ) and low sleep quality (LSQ) groups. After drinking coffee, however, participants with HSQ demonstrated improvements in vigilance and reaction time, while the LSQ group had improved vigilance only. Conclusion Low dose caffeine improved vigilance, situational awareness, and reaction time which were cognitive functions required for flight performance. The cognitive-enhancing effect of caffeine was more obvious in student pilots with high-quality sleep.

Direct and Indirect Effects of Blood Levels of Omega-3 and Omega-6 Fatty Acids on Reading and Writing (Dis)Abilities.

The purpose of the present study was to investigate whether there are associations between polyunsaturated fatty acid (PUFA) blood levels, reading/writing performance and performance in neuropsychological tasks. Moderate to strong correlations were found between PUFA levels (specific omega-6/omega-3 ratios) and reading/writing abilities, and the former and neuropsychological test scores. Mediation models analyzing the direct and indirect effects of PUFA on reading and writing scores showed that the effects of fatty acids on learning measures appear to be direct rather than mediated by the investigated visual and auditory neuropsychological mechanisms. The only significant indirect effect was found for the difference in accuracy between the left and right visual fields in visual-spatial cueing tasks, acting as a mediator for the effect of PUFA ratios on writing accuracy. Regression analyses, by contrast, confirmed the roles of phonological awareness and other visual attentional factors as predictors of reading and writing skills. Such results confirm the crucial role of visual-spatial attention mechanisms in reading and writing, and suggest that visual low-level mechanisms may be more sensitive to the effects of favorable conditions related to the presence of higher omega-3 blood levels.

Graph Analysis of Verbal Fluency Tests in Schizophrenia and Bipolar Disorder.

Verbal Fluency Tests (VFT) are one of the most common neuropsychological tasks used in bipolar disorder (BD) and schizophrenia (SZ) research. Recently, a new VFT analysis method based on graph theory was developed. Interpreting spoken words as nodes and every temporal connection between consecutive words as edges, researchers created graph structures, allowing the extraction of more data from participants’ speech, called Speech Graph Attributes (SGA). The aim of our study was to compare speech graphs, derived from Phonemic and Semantic VFT, between SZ, BD, and healthy controls (HC). Twenty-nine SZ patients, twenty-nine BD patients, and twenty-nine HC performed Semantic and Phonemic VFT. Standard measures (SM) and 13 SGA were analyzed. SZ patients’ Semantic VFT graphs showed lower total word count and correct responses. Their graphs presented less nodes and edges, higher density, smaller diameter, average shortest path (ASP), and largest strongly connected component than the HC group. SM did not differentiate BD and HC groups, and patients’ Semantic VFT graphs presented smaller diameter and ASP than HC. None of the parameters differentiated BD and SZ patients. Our results encourage the use of speech graph analysis, as it reveals verbal fluency alterations that remained unnoticed in the routine comparisons of groups with the use SM.

Classic Psychedelic Drugs: Update on Biological Mechanisms

Renewed interest in the effects of psychedelics in the treatment of psychiatric disorders warrants a better understanding of the neurobiological mechanisms underlying the effects of these substances. During the past two decades, state-of-the-art studies of animals and humans have yielded new important insights into the molecular, cellular, and systems-level actions of psychedelic drugs. These efforts have revealed that psychedelics affect primarily serotonergic receptor subtypes located in cortico-thalamic and cortico-cortical feedback circuits of information processing. Psychedelic drugs modulate excitatory-inhibitory balance in these circuits and can participate in neuroplasticity within brain structures critical for the integration of information relevant to sensation, cognition, emotions, and the narrative of self. Neuroimaging studies showed that characteristic dimensions of the psychedelic experience obtained through subjective questionnaires as well as alterations in self-referential processing and emotion regulation obtained through neuropsychological tasks are associated with distinct changes in brain activity and connectivity patterns at multiple-system levels. These recent results suggest that changes in self-experience, emotional processing, and social cognition may contribute to the potential therapeutic effects of psychedelics.

Only minimal differences between individuals with congenital aphantasia and those with typical imagery on neuropsychological tasks that involve imagery

Aphantasia describes the experience of individuals who self-report a lack of voluntary visual imagery. It is not yet known whether individuals with aphantasia show deficits in cognitive and neuropsychological tasks thought to relate to aspects of visual imagery, including Spatial Span, One Touch Stocking of Cambridge, Pattern Recognition Memory, Verbal Recognition Memory and Mental Rotation. Twenty individuals with congenital aphantasia (VVIQ < 25) were identified and matched on measures of age and IQ to twenty individuals with typical imagery (VVIQ > 35). A group difference was found in the One Touch Stocking of Cambridge task for response time, but not accuracy, when the number of imagined moves that participants had to hold in their heads to complete the task increased. Similarly, a group difference in response time was apparent in the mental rotation task, but only in the subgroup of aphantasic participants who reported a severe deficit in visual imagery (VVIQ score of 16). These results suggest that the cognitive profile of people without imagery does not greatly differ from those with typical imagery when examined by group. In addition, the severity of aphantasia (and VVIQ criterion) may be an important factor to consider when investigating differences in imagery experience. Overall, this study raises questions about whether or not aphantasia represents a difference in cognitive function or in conscious experience.

Neuropsychological exponents for the driving ability in remitted bipolar patients

BackgroundBipolar disorder (BD) is associated with cognitive deficits regardless of the phase of the disease. Medications used in treatment are an additional factor that may affect cognitive performance. Poor cognitive performance can significantly affect a patient's ability to drive.Aim of the studyThis study aims to explore cognitive functions relevant for safe driving in the group of remitted bipolar patients.MethodPatients with BD in remission (n = 33) and healthy volunteers (n = 32) were included. Selected psychometric tests for drivers were carried out using computer software: called Specialistic Diagnostic Platform (SPD): The Cross-over Test (COT) version with free tempo (COT-F) and tempo of 50 tasks per minute (COT-50) and the Signal Test (ST). Moreover, the following neuropsychological tests were used: Rey Auditory Verbal Learning Test (RAVLT), Stroop Color-Word Test (SCWT) part A and B, and Trail Making Test (TMT) version A and B.ResultsIn comparison with healthy controls bipolar patients in remission had poorer outcomes for some cognitive parameters and longer reaction times in both tests for drivers and neuropsychological tests. Additionally, we found a significant correlation between the time of performance of neuropsychological tests and the time of psychometric tests for drivers.ConclusionPatients with BD performed worse in several cognitive domains assessed by tests for drivers and neuropsychological tasks. These deficits can affect the speed of the patient's motor reactions while driving.

Diferencias en la atención sostenida en jóvenes universitarios con distintos niveles de uso de smartphone

The constant use of mobile devices changed our lives dramatically during the past years and its usage increased over the years. Smartphone use is associated with isolation and interpersonal problems; its overuse can cause cognitive problems too (Matar Boumosleh &amp; Jaalouk, 2017). Cognitive problems associated with smartphones in young people are reduction of sustained attention and working memory. Findings have been reported in which younger populations show deterioration in different components of care, highlighting the difficulty of walking and using the smartphone at the same time (Prupetkaew et al., 2019). It has been reported that the impulsivity associated with use of smartphone in silent mode interferes in memory tests unlike when it is in off mode in young populations (Canale et al., 2019). It is necessary to evaluate the effects of using a smartphone on young people because it is a population that uses it constantly to develop in work, academic, sports, and even socializing activities. The aim of this paper was to find out the differences in sustained attention in young university students with different levels of smartphone use. A sample of 94 adults, 34 men and 60 women between the ages of 18 and 23 (M = 19.34, SD = 1.09), who were students of the higher school of Actopan, Hidalgo-Mexico. The EDAS –Smartphone Dependency and Addiction Scale– was applied (Aranda-López et al., 2017). For the evaluation of attention, a Computerized Continuous Running Test (CPT), Test of Attentional Vigilance (TOAV) was applied using the Psychology Experimental Building Language PEBL-2 platform (Mueller &amp; Pipper, 2014). The inclusion criteria were that the participants were between 18-23 years old, right-handed, with normal and/or corrected vision. They were excluded from the investigation if they had a history of psychiatric and/or neurological diseases, learning difficulties, chronic alcohol and/or drug use. A one-way ANOVA was performed, where the independent variable was the level of smartphone use (no dependence, dependence and addiction) and the dependent variable was the scores obtained in the TOAV. It was observed that there are statistically significant differences in the errors of omission of the second half of the test (p = .05), the differences were found between the groups of no dependence-dependence (p =.10) and without dependence-addiction (p = .24). The results showed that there are differences in the execution of a neuropsychological task, regarding the omission errors of the second part of the test. These differences could suggest that the level of sustained attention is diminished in the participants of the dependency and addiction group at the end of the task. On the other hand, it is also concluded that students with levels of dependence and smartphone addiction face attention difficulties when the task is longer and cognitive demand increases. This type of data must be analyzed taking into consideration variables such as sex, socioeconomic level, age, profile of use, quality of sleep, level of physical activity, among others. https://doi.org/10.16888/interd.2022.39.2.2

Similar Profile and Magnitude of Cognitive Impairments in Focal and Generalized Epilepsy: A Pilot Study.

Introduction: Cognitive impairments in epilepsy are not well-understood. In addition, long-term emotional, interpersonal, and social consequences of the underlying disturbances are important to evaluate.Purpose: To compare cognitive function including language in young adults with focal or generalized epilepsy. In addition, quality of life and self-esteem were investigated.Patients and Methods: Young adults with no primary intellectual disability, 17 with focal epilepsy and 11 with generalized epilepsy participated and were compared to 28 healthy controls. Groups were matched on age (mean = 26 years), sex, and education. Participants were administered a battery of neuropsychological tasks and carried out self-ratings of quality of life, self-esteem, and psychological problems.Results: Similar impairments regarding cognitive function were noted in focal and generalized epilepsy. The cognitive domains tested were episodic long-term memory, executive functions, attention, working memory, visuospatial functions, and language. Both epilepsy groups had lower results compared to controls (effect sizes 0.24–1.07). The total number of convulsive seizures was predictive of episodic long-term memory function. Participants with focal epilepsy reported lower quality of life than participants with generalized epilepsy. Lowered self-esteem values were seen in both epilepsy groups and particularly in those with focal epilepsy. Along with measures of cognitive speed and depression, the total number of seizures explained more than 50% of variation in quality of life.Conclusion: Interestingly, similarities rather than differences characterized the widespread cognitive deficits that were seen in focal and generalized epilepsy, ranging from mild to moderate. These similarities were modified by quality of life and self-esteem. This study confirms the notion that epilepsy is a network disorder.

The The Role of Executive Functioning in Understanding Chronic Pain Experiences in Adolescence: A Pilot Multi-Method Study

Background: Optimal executive functioning is pivotal to successful self-management of chronic pain (e.g., by being able to adapt self-management behaviours to changing situations), thereby contributing to improved health-related quality of life. However, preliminary evidence points to impaired executive functioning in people with chronic pain. Despite adolescence being identified as a sensitive period for the development of appropriate self-management and executive functioning skills, little is known about the associations between chronic pain and executive functioning performance in adolescents. The aim of the study was to pilot a multi-method approach to compare executive functioning, chronic pain, and quality of life between adolescents with and without chronic pain. Methods: A sample of 22 adolescents with chronic pain (12-18 years, 82% female, mean chronic pain duration = 6.68 years) and 13 pain-free adolescents (age and sex matched) participated. All participants completed a battery of neuropsychological tasks to assess the three key executive functioning components (i.e., inhibition, working memory and cognitive flexibility) and provided self-report on their executive functioning, pain experiences and health-related quality of life. Results: In addition to confirming the feasibility of the methods, data revealed that 23-62% of adolescents with chronic pain showed problematic performance, using normative scoring, in all three executive functioning components and showed significantly lower performance on all three executive functioning components compared to pain-free adolescents. Self-reported, but not neuropsychologically assessed, working memory and emotional control difficulties were associated with more pain-related interference and lower health-related quality of life. Conclusion: These preliminary findings reveal the critical need to screen for and address any potential deficits in executive functioning in adolescents with chronic pain to optimise their self-management of pain and subsequent health-related quality of life. The findings also illustrate the feasibility of and need for future systematic, multi-method and prospective investigations in larger samples to further clarify the cyclical associations between chronic pain and executive functioning in adolescents.
