The objective of this study was to examine visual scanning performance in patients with Unilateral Spatial Neglect (USN) in a visual search task. Thirty-one right hemisphere stroke patients with USN were recruited. They performed a dynamic visual search task with two conditions, with and without distractors, while eye movements were monitored with an eye-tracker. The main goal of the task was to select target stimuli that appeared from the top of the screen and moved vertically downward. Target detection and visual scanning percentage were assessed over two hemispaces (right, left) on two conditions (distractor, no distractor). Most Scanned Regions (MSR) were calculated to analyze the areas of the screen where most points of fixation were directed to. Higher target detection rate and visual scanning percentages were found on the right hemispace on both conditions. From the MSRs we found that participants with a center of attention further to the right of the screen also presented smaller overall MSRs. Right hemisphere stroke patients with USN presented not only a significant rightward bias but reduced overall search areas, implying hyperattention does not only restrict search on the horizontal (right-left) axis but the vertical axis (top-bottom) too.

Background: Visuo-spatial neglect predicts longer hospitalization, poorer recovery of motor skills and greater functional limitation. The aim of the present study was to analyze whether the combined administration of computerized cognitive rehabilitation with right hemifield eye-patching in patients with left spatial neglect following a right hemisphere stroke is more effective than computerized cognitive rehabilitation applied in isolation. Method: Randomized clinical trial conducted in 28 patients. These were grouped into two experimental groups: single treatment group (ST) (n= 15) and combined treatment group (CT) (n= 13). All received an average of 15 one-hour sessions of computerized cognitive rehabilitation using the Guttmann, NeuroPersonalTrainer® telerehabilitation platform. Those patients in the TC group performed the sessions wearing a visual device with which the right hemifield of each eye was occluded. Results: Following treatment, both the ST and the TC group showed improvements in neuropsychological examination protocol although there were no differences pre- and post-treatment on the functional scale in either group. Likewise, no statistically significant differences were observed in intergroup comparison. Conclusions: The results from this study indicate that combination treatment is not more effective than rehabilitation applied in isolation. [ABSTRACT FROM AUTHOR]

Objective: To assess whether, following a right-hemisphere stroke, the combined administration of computer-based cognitive rehabilitation and right hemifield eye-patching in patients with visuo-spatial neglect is more effective than computer-based cognitive rehabilitation alone. Methods: Twelve patients were randomized into two treatment groups: a single treatment group ( n = 7) and a combination treatment group ( n = 5). In both cases, the treatment consisted of a mean number of 15 sessions, each lasting 1 hour. Visuo-spatial neglect was assessed using a specific exploration protocol (Bell Cancellation Test, Figure Copying of Odgen, Line Bisection, Baking Tray Task and Reading Task). The functional effects of the treatment were assessed using the Catherine Bergego Scale. Results: Significant between-group differences were observed when comparing the pre- and post-treatment scores for the Reading Task. No differences were observed in either group in the Catherine Bergego Scale administered at baseline and at the final intervention. Conclusion: The results obtained do not allow one to conclude that the combination treatment with cognitive rehabilitation and right hemifield eye-patching is more effective than cognitive rehabilitation alone. Although partial improvement in the performance of neuropsychological tests was observed, this improvement is not present at functional level. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: A descriptive review of the visuospatial hemineglect associated with strokes. Most relevant clinical and theoretical aspects are addressed and the different intervention techniques currently used. Development: The visuo-spatial hemineglect is a multimodal neuropsychological deficit associated with brain lesions, mainly of vascular origin. Their presence implies a slower recovery, increased disability and poor response to rehabilitation. Although spontaneous recovery can occur within the first few weeks or months, the passage of time does not necessarily imply an improvement of symptoms. Currently multiple strategies for rehabilitation have been developed, but very few demonstrate lasting effects over time. Conclusions: The prism adaptation is the technique where best results are obtained, although there are controversies regarding its long-term benefits. The various operations described in the article have a transitory impact and the results do not usually translate into an improvement in activities of daily living. Current trends are betting on the combined application of various techniques. [ABSTRACT FROM AUTHOR]

Iowa Gambling Task. Cognitive dysfunction has been widely studied in multiple sclerosis (MS), however decision-making has been less investigated. The current study examined the decision-making processes of patients with multiple sclerosis (MS) using a computerized version of the Iowa Gambling Task (IGT). This task was applied to 18 patients with clinically diagnosed MS and 18 healthy control subjects matched for age, sex, and years of education. The results showed that IGT scores differ significantly between patients with MS and the healthy control subjects: the patients with MS made significantly less advantageous decisions than the controls in the lGT. Possible causes of impaired decision-making in multiple sclerosis are discussed. [ABSTRACT FROM AUTHOR]

Introduction: This is a 12-weeks randomized controlled trial examining the effects of aerobic exercise (AE), computerized cognitive training (CCT) and their combination (COMB). We aim to investigate their impact on cardiovascular health and white matter (WM) integrity and how they contribute to the cognitive benefits. Methods: 109 participants were recruited and 82 (62% female; age = 58.38 ± 5.47) finished the intervention with > 80% adherence. We report changes in cardiovascular risk factors and WM integrity (fractional anisotropy (FA); mean diffusivity (MD)), how they might be related to changes in physical activity, age and sex, and their potential role as mediators in cognitive improvements. Results: A decrease in BMI (SMD = − 0.32, p = 0.039), waist circumference (SMD = − 0.42, p = 0.003) and diastolic blood pressure (DBP) (SMD = − 0.42, p = 0.006) in the AE group and a decrease in BMI (SMD = − 0.34, p = 0.031) and DBP (SMD = − 0.32, p = 0.034) in the COMB group compared to the waitlist control group was observed. We also found decreased global MD in the CCT group (SMD = − 0.34; p = 0.032) and significant intervention-related changes in FA and MD in the frontal and temporal lobes in the COMB group. Conclusions: We found changes in anthropometric measures that suggest initial benefits on cardiovascular health after only 12 weeks of AE and changes in WM microstructure in the CCT and COMB groups. These results add evidence of the clinical relevance of lifestyle interventions and the potential benefits when combining them. Clinical Trial Registration: ClinicalTrials.gov NCT031123900.

This prospective, observational cohort study investigated the effects of multidisciplinary rehabilitation of post Covid-19 sequelae and persistent symptoms and their impact on patients' functioning and quality of life. From 58 patients referred for neurorehabilitation, 43 were eligible for and participated in the present study. Before and after 8 weeks of rehabilitation, patients underwent physical, neuropsychological and respiratory evaluations and assessment of functional independence, impact of fatigue and quality of life. Forty of 43 individuals (52 ± 11.4 years, 24 male) completed the rehabilitation program. Fatigue (87.5%), dyspnea and/or shortness of breath (62.5%), and cognitive impairment (37.5%) were reported by both previously hospitalized and home-confined patients. Neurological sequelae (35.5%) were present only in hospitalized patients. After 8 weeks of rehabilitation, patients reported significant improvements in motor functional independence, upper and lower limb functionality, impact of fatigue on daily activities, respiratory muscle strength, cognitive performance, and quality of life. Post Covid-19 patients present with heterogeneous neurological, physical, and respiratory impairments requiring a multidisciplinary rehabilitation approach to reduce disability and improve functionality and quality of life. A comprehensive assessment of clinical profiles and responses to rehabilitation may facilitate the identification of rehabilitation candidates and help to design effective rehabilitation interventions. Post Covid-19 patients present multiple, heterogeneous neurological, physical and respiratory impairments that are observed in both previously hospitalized and home-confined patients. Eight weeks of multidisciplinary rehabilitation may significantly reduce disability and improve functionality and quality of life. A comprehensive assessment of their clinical profile and response to rehabilitation may facilitate the identification of rehabilitation candidates and help to design more effective rehabilitation interventions.

- Abstract
Introduction: Although impairment in decision-making is a frequent consequence of frontal lobe injury, few instruments evaluate decision-making in patients with acquired brain injury (ABI). Most are difficult to use and require a well-preserved ability of complex verbal comprehension and executive functions. We propose the Balloon Analogue Risk Task (BART) as an alternative instrument to evaluate decision-making in ABI. Material and Methods: Balloon Analogue Risk Task (BART) and Iowa Gambling Task (IGT) were administered to a clinical group of 30 patients with ABI and to a control group of 30 healthy participants; comparative study to assess possible differences in the results obtained; analysis to determine a possible correlation between the two tests between groups. Results: The results showed that BART is a sensitive instrument to detect differences in performance between a control group and a group of patients with ABI, p < .001, 95 % CI =537.21-1575.46, but do not correlate with IGT, p = .524, rab.c = -.134. Conclusions: Although IGT and BART were both designed to assess decision-making, the results obtained in our study show that the scores obtained by patients with ABI on both tests do not correlate. This clearly proves that IGT and BART measure different aspects of decision-making. [ABSTRACT FROM AUTHOR]

Computerized Cognitive Training (CCT) is an effective treatment for cognitive impairment in the post-acute stage of stroke. However, it is still not clear if it is suitable for chronic stage. To explore if patients with cognitive deficit following stroke may benefit from CCT. Thirty patients post-stroke between 24 and 62 years old were randomized into two groups (A and B) to receive two different types of CCT. All patients were tested with a neuropsychological battery and functional questionnaires, before and after each CCT and also 6 months after the end of the study. In phase I, Group A received a customized CCT and Group B received a non-customized CCT, over 6 weeks. Three months after, each group received the other intervention (phase II). After phase I, between-group analyses revealed that Group A showed a relative decrease in subjective complaints. In contrast, Group B showed improvement in performance-based measures. After phase II, the decrease in subjective complaints continued in Group A, and both groups showed improvement in performance-based measures. Patients with chronic stroke improved cognitive functioning after performing supervised home-based multi-domain computerized cognitive training. [ABSTRACT FROM AUTHOR]

- Abstract
Background: This paper presents the design, development and first evaluation of an algorithm, named Intelligent Therapy Assistant (ITA), which automatically selects, configures and schedules rehabilitation tasks for patients with cognitive impairments after an episode of Acquired Brain Injury. The ITA is integrated in “Guttmann, Neuro Personal Trainer” (GNPT), a cognitive tele-rehabilitation platform that provides neuropsychological services. Methods: The ITA selects those tasks that are more suitable for the specific needs of each patient, considering previous experiences, and improving the personalization of the treatment. The system applies data mining techniques to cluster the patients according their cognitive impairment profile. Then, the algorithm rates every rehabilitation task, based on its cognitive structure and the clinical impact of executions done by similar patients. Finally, it configures the most suitable degree of difficulty, depending on the impairment of the patient and his/her evolution during the treatment. Results: The ITA has been evaluated during 18 months by 582 patients. In order to evaluate the effectiveness of the ITA, a comparison between the traditional manual planning procedure and the one presented in this paper has been done, taking into account: a) the selected tasks assigned to rehabilitation sessions; b) the difficulty level configured for the sessions; c) and the improvement of their cognitive capacities after completing treatment. Conclusions: The obtained results reveal that the rehabilitation treatment proposed by the ITA is as effective as the one performed manually by therapists, arising as a new powerful support tool for therapists. The obtained results make us conclude that the proposal done by the ITA is very close to the one done by therapists, so it is suitable for real treatments. [ABSTRACT FROM AUTHOR]

- Abstract
Aim: Cerebral palsy (CP) in children can be associated with attention deficits, executive dysfunction or alterations in visuoperceptive abilities. Understanding these deficits and possible therapeutic approaches may improve their quality of life. Methods: In this study, review has been carried out into literature about definition, classification, cognitive profiles and, specially, cognitive stimulation of children with CP, given the limited number of publications on this aspect of neurorehabilitation. Results: Stimulating cognitive development in order to improve quality of life, behaviour and functionality of these children may lead to changes in neuroplasticity. Technique integration, coupled with speech intervention and physiotherapeutic treatment can improve cognition and motivation in children with CP at family and school levels. Conclusions: Children affected by CP and cognitive deficits can benefit from cognitive stimulation and thus improve their quality of life. Clinicians should offer therapeutic intervention focused on children with CP, while not ignoring school and family environment. [ABSTRACT FROM AUTHOR]

Rehabilitation can improve cognitive deficits observed in patients with traumatic brain injury (TBI). However, despite rehabilitation, the ability of making a choice often remains impaired. Risk taking is a daily activity involving numerous cognitive processes subserved by a complex neural network. In this work we investigated risk taking using the Balloon Analogue Risk Task (BART) in patients with acute TBI and healthy controls. We hypothesized that individuals with TBI will take less risk at the BART as compared to healthy individuals. We also predicted that within the TBI group factors such as the number of days since the injury, severity of the injury, and sites of the lesion will play a role in risk taking as assessed with the BART. Main findings revealed that participants with TBI displayed abnormally cautious risk taking at the BART as compared to healthy subjects. Moreover, healthy individuals showed increased risk taking throughout the task which is in line with previous work. However, individuals with TBI did not show this increased risk taking during the task. We also investigated the influence of three patients’ characteristics on their performance at the BART: Number of days post injury, Severity of the head injury, and Status of the frontal lobe. Results indicate that performance at the BART was influenced by the number of days post injury and the status of the frontal lobe, but not by the severity of the head injury. Reported findings are encouraging for risk taking seems to naturally improve with time postinjury. They support the need of conducting longitudinal prospective studies to ultimately identify impaired and intact cognitive skills that should be trained postinjury. [ABSTRACT FROM AUTHOR]

BACKGROUND: Coronavirus disease 2019 (COVID-19) patients present long-lasting physical and neuropsychological impairment, which may require rehabilitation. OBJECTIVES: The current cross-sectional study characterizes post COVID-19 sequelae and persistent symptoms in patients in an outpatient rehabilitation program. METHODS: Thirty patients [16 post-ICU and 14 non-ICU; median age = 54(43.8–62) years; 19 men] presenting sequelae and/or persistent symptoms (>3 months after acute COVID-19) were selected of 41 patients referred for neurorehabilitation. Patients underwent physical, neuropsychological and respiratory evaluation and assessment of impact of fatigue and quality of life. RESULTS: The main reasons for referral to rehabilitation were: fatigue (86.6%), dyspnea (66.7%), subjective cognitive impairment (46.7%) and neurological sequelae (33.3%). Post-ICU patient presented sequelae of critical illness myopathy and polyneuropathy, stroke and encephalopathy and lower forced vital capacity compared to non-ICU patients. Cognitive impairment was found in 63.3% of patients, with a similar profile in both sub-groups. Increased physical fatigue, anxiety and depression and low quality of life were prevalent irrespective of acute COVID-19 severity. CONCLUSIONS: The variability of post COVID-19 physical and neuropsychological impairment requires a complex screening process both in ICU and non-ICU patients. The high impact of persistent symptoms on daily life activities and quality of life, regardless of acute infection severity, indicate need for rehabilitation. [ABSTRACT FROM AUTHOR]

Objectives: How brain damage after stroke is related to specific clinical manifestation and recovery is incompletely understood. We studied cognitive reserve (CR) in stroke patients by two types of measurements: (i) objectively verifiable static proxies (i.e., education, occupational attainment), and (ii) subjective, dynamic proxies based on patient testimony in response to a questionnaire. We hypothesized that one or both of these types of CR measurements might correlate positively with patient cognitive performance during the post-acute and chronic phases of recovery. Method: Thirty-four stroke patients underwent neuropsychological assessment at 2, 6 and 24 months after stroke onset. In chronic stage at 24+ months, self-rating assessments of cognitive performance in daily life and social integration were obtained. CR before and after stroke was estimated using static proxies and dynamic proxies were obtained using the Cognitive Reserve Scale (CRS-Pre-stroke, CRS-Post-stroke). Results: CRS-Pre-stroke and CRS-Post-stroke showed significant mean differences. Dynamic proxies showed positive correlation with self-assessment of attention, metacognition, and functional ability in chronic stage. In contrast, significant correlations between static proxies and cognitive recovery were not found. Conclusions: Dynamic proxies of CR were positively correlated with patients' perception of their functional abilities in daily life. To best guide cognitive prognosis and treatment, we propose that dynamic proxies of CR should be included in neuropsychological assessments of patients with brain damage. [ABSTRACT FROM AUTHOR]

Background: Stroke patients usually suffer primary cognitive impairment related to attention, memory, and executive functions. This impairment causes a negative impact on the quality of life of patients and their families, and may be long term. Cognitive rehabilitation has been shown to be an effective way to treat cognitive impairment and should be continued after hospital discharge. Computerized cognitive rehabilitation can be performed at home using exercise programs that advance with predetermined course content, interval, and pace. We hypothesize that computerized rehabilitation might be improved if a program could customize course content and pace in response to patient-specific progress. The present pilot study is a randomized controlled double-blind crossover clinical trial aiming to study if chronic stroke patients with cognitive impairment could benefit from cognitive training through a customized tele-rehabilitation platform ("Guttmann, NeuroPersonalTrainer"®, GNPT®).Methods/design: Individuals with chronic-stage stroke will be recruited. Participants will be randomized to receive experimental intervention (customized tele-rehabilitation platform, GNPT®) or sham intervention (ictus.online), both with the same frequency and duration (five sessions per week over 6 weeks). After a washout period of 3 months, crossover will occur and participants from the GNPT® condition will receive sham intervention, while participants originally from the sham intervention will receive GNPT®. Patients will be assessed before and after receiving each treatment regimen with an exhaustive neuropsychological battery. Primary outcomes will include rating measures that assess attention difficulties, memory failures, and executive dysfunction for daily activities, as well as performance-based measures of attention, memory, and executive functions.Discussion: Customized cognitive training could lead to better cognitive function in patients with chronic-stage stroke and improve their quality of life.Trial Registration: NCT03326349 .
