RESUMO
OBJECTIVE: The purpose of this cross-sectional retrospective study was to utilize EpiTrack to assess cognitive performance within the domain of attention and executive functions in patients with refractory epilepsy in consideration for treatment interventions either with antiepileptic drug (AED) changes and/or neuromodulation therapies. We also aimed to identify the relevant clinical and treatment factors possibly affecting EpiTrack performance. METHODS: The patient group consisted of 95 consecutive refractory epilepsy patients who were evaluated with EpiTrack. Based on their EpiTrack performance, the patients could be categorized as cognitively unimpaired, mildly, or severely impaired. The patients were also divided into three groups based on the planned treatment modification: AED group (nâ¯=â¯38) with only AED treatment, vagal nerve stimulation (VNS) group (nâ¯=â¯40) and deep-brain stimulation (DBS) group (nâ¯=â¯17). However, the effect of planned interventions was not the subject of this study. We retrospectively reviewed the medical records for detailed clinical characterization. RESULTS: EpiTrack performance was severely impaired in 48 (50.5%), mildly impaired in 22 (23.2%) and unimpaired in 25 (26.3%) of the patients. The DBS group had significantly lower EpiTrack scores (mean (SD) and median, 25.5 (4.81) and 27.0, respectively) compared to the AED group (28.6 (6.2) and 30.0, respectively, pâ¯=â¯0.049). Sixty-three (66.3%) of the whole study population had more than 2 AEDs. When comparing EpiTrack scores between patient groups based on the number of AEDs administered, there was a trend toward better performance in EpiTrack with 2 AEDs as compared to 3-4 AEDs. CONCLUSIONS: Deficits in attention and executive functions were frequent among patients with refractory epilepsy. Deficits were evident in all three treatment groups being most severe in the DBS group reflecting the patient selection. Furthermore, the effect of AED burden on executive functions was remarkable since two thirds of the patients had more than two AEDs and the deficits were more prominent among those with a higher AED burden. These results highlight the benefits of a feasible screening tool such as EpiTrack for assessing attention and executive functions when optimizing the treatment effects of neurostimulation therapies on cognition, and when evaluating the impacts of the AED burden.

OBJECTIVE: To examine resilience as a predictor of change in self-reported fatigue after mild traumatic brain injury (MTBI). PARTICIPANTS: A consecutive series of 67 patients with MTBI and 34 orthopedic controls. DESIGN: Prospective longitudinal study. MAIN MEASURES: Resilience Scale, Beck Depression Inventory-Second Edition, and Pain subscale from Ruff Neurobehavioral Inventory 1 month after injury and Barrow Neurological Institute Fatigue Scale 1 and 6 months after injury. RESULTS: Insomnia, pain, and depressive symptoms were significantly correlated with fatigue, but even when these variables were controlled for, resilience significantly predicted the change in fatigue from 1 to 6 months after MTBI. In patients with MTBI, the correlation between resilience and fatigue strengthened during follow-up. In controls, significant associations between resilience and fatigue were not found. CONCLUSION: Resilience is a significant predictor of decrease in self-reported fatigue following MTBI. Resilience seems to be a relevant factor to consider in the management of fatigue after MTBI along with the previously established associated factors (insomnia, pain, and depressive symptoms).

BACKGROUND: There is preliminary evidence on the positive effects of neuropsychological rehabilitation on cognition in multiple sclerosis (MS), but the generalisability of the findings is limited by methodological problems. OBJECTIVE: The aim of the present study was to determine the effects of strategy-oriented neuropsychological rehabilitation on MS. METHODS: A total of 102 relapsing-remitting MS patients with subjective and objective attentional deficits were randomised into an intervention and a control group. Neuropsychological assessments were performed at baseline, at three months immediately after the intervention, and at six months. Patients in the intervention group received neuropsychological rehabilitation once a week in 60-minute sessions for 13 consecutive weeks. The control group received no intervention. RESULTS: Neuropsychological rehabilitation including computer-based attention and working memory retraining, psychoeducation, strategy learning and psychological support did not improve cognitive performance but had a positive effect on perceived cognitive deficits. The intervention group perceived significantly fewer deficits than the control group both immediately after the intervention and at six months. The personal rehabilitation goals were also well achieved. CONCLUSIONS: Strategy-oriented neuropsychological rehabilitation did not improve cognitive performance but reduced perceived cognitive deficits in MS.

BACKGROUND: This is an update of the Cochrane review 'Neuropsychological rehabilitation for multiple sclerosis' (first published in The Cochrane Library 2011, Issue 11).Cognitive deficits are a common manifestation of multiple sclerosis (MS) and have a significant effect on the patient's quality of life. Alleviation of the harmful effects caused by these deficits should be a major goal of MS research and practice. OBJECTIVES: To assess the effects of neuropsychological/cognitive rehabilitation on health-related factors, such as cognitive performance and emotional well-being in patients with MS. SEARCH METHODS: The Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Trials Search Co-ordinator searched their Specialised Register which, among other sources, contains trials from CENTRAL (The Cochrane Library 2013, Issue 2), MEDLINE, EMBASE, CINAHL, LILACS, PEDro and clinical trials registries (28 May 2013). We contacted authors of the studies for additional information. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-randomised trials evaluating the effects of neuropsychological rehabilitation in MS compared to other interventions or no intervention. DATA COLLECTION AND ANALYSIS: Two review authors individually judged the eligibility of the included studies, assessed risk of bias and extracted data. We combined results quantitatively in meta-analyses according to the intervention type: 1) cognitive training and 2) cognitive training combined with other neuropsychological rehabilitation methods. MAIN RESULTS: Twenty studies (986 participants; 966 MS participants and 20 healthy controls) fulfilled the inclusion criteria. The mean age of the participants was 44.6 years, mean length of education was 12.3 years and 70% of the participants were women. Most of the participants had a relapsing-remitting course of disease. The mean Expanded Disability Status Scale score was 3.2 and the mean duration of disease was 14.0 years.On the basis of these studies, we found low-level evidence that neuropsychological rehabilitation reduces cognitive symptoms in MS. Cognitive training was found to improve memory span (standardised mean difference (SMD) 0.54, 95% confidence interval (CI) 0.20 to 0.88, P = 0.002) and working memory (SMD 0.33, 95% CI 0.09 to 0.57, P = 0.006). Cognitive training combined with other neuropsychological rehabilitation methods was found to improve attention (SMD 0.15, 95% CI 0.01 to 0.28, P = 0.03), immediate verbal memory (SMD 0.31, 95% CI 0.08 to 0.54, P = 0.008) and delayed memory (SMD 0.22, 95% CI 0.02 to 0.42, P = 0.03). There was no evidence of an effect of neuropsychological rehabilitation on emotional functions.The overall quality, as well as the comparability of the included studies, was relatively low due to methodological limitations and heterogeneity of interventions and outcome measures. Although most of the pooled results in the meta-analyses yielded no significant findings, 18 of the 20 studies showed some evidence of positive effects when the studies were individually analysed. AUTHORS' CONCLUSIONS: This review found low-level evidence for positive effects of neuropsychological rehabilitation in MS. The interventions and outcome measures included in the review were heterogeneous, which limited the comparability of the studies. New trials may therefore change the strength and direction of the evidence.

OBJECTIVE: To investigate executive functions and attention with repeated EpiTrack evaluations in a group of DR patients with drug-resistant epilepsy (DRE) receiving vagus nerve stimulation (VNS) during a follow-up duration of up to 5 years. METHODS: The study involved 33 patients with DRE who were assessed with EpiTrack as a part of the clinical VNS protocol. Evaluations were scheduled prior to VNS implantation and then at 6 months, 12 months, and yearly thereafter. However, the COVID-19 pandemic disrupted follow-up. Therefore, changes in EpiTrack total scores over time were analyzed using a linear mixed-effects (LMEs) model to compensate for the variation in follow-up duration when predicting EpiTrack total score changes over 5 years. RESULTS: The median follow-up time was 29 months. During each month, the EpiTrack total score was predicted to increase by 0.07 units (95% confidence interval [CI]: 0.01-0.12, P = 0.02), corresponding to a change from a baseline score of 27.3 (severe impairment) to a score of 28.9 (mild impairment) at 2 years and a score of 31.5 (almost normal) at 5 years. In the group of patients with psychiatric comorbidities, the EpiTrack total score increased by 0.14 units per month (P = 0.003), which was 3.5-fold higher than the increase of patients without psychiatric comorbidities. For the patients taking 1-2 antiseizure medications (ASMs), the EpiTrack total score increased by 0.11 units per month (P = 0.005), which was almost quadruple the rate of patients taking 3-4 ASMs. SIGNIFICANCE: Based on EpiTrack total scores, the LME model predicted a four-point improvement in executive functions among patients with DRE at 5 years after the initiation of VNS, representing a clinically meaningful change. DRE patients with comorbid depression seemed to experience the most cognitive benefits. In addition, better cognitive outcomes were achieved if the patient took less than three ASMs. PLAIN LANGUAGE SUMMARY: Executive functions and attention may improve during vagus nerve stimulation therapy in patients with drug-resistant epilepsy. Epilepsy patients who have depression or use fewer than three antiseizure medications are likely to benefit cognitively more from the treatment.

Introduction: There is a paucity of clinical studies examining the long-term effects of vagus nerve stimulation (VNS) on cognition, although a recent study of patients with drug-resistant epilepsy (DRE) treated with VNS therapy demonstrated significant improvement in executive functions as measured by the EpiTrack composite score. The present study aimed to investigate performance variability in three cognitive tests assessing executive functions and working memory in a cohort of DRE patients receiving VNS therapy during a follow-up duration of up to 5 years. Methods: The study included 46 DRE patients who were assessed with the Trail Making Test (TMT) (Parts A and B) and Digit Span Backward (DB) task prior to VNS implantation, 6 months and 12 months after implantation, and yearly thereafter as a part of the clinical VNS protocol. A linear mixed-effects (LME) model was used to analyze changes in test z scores over time, accounting for variations in follow-up duration when predicting changes over 5 years. Additionally, we conducted descriptive analyses to illustrate individual changes. Results: On average, TMT-A z scores improved by 0.024 units (95% confidence interval (CI): 0.006 to 0.042, p = 0.009), TMT-B z scores by 0.034 units (95% CI: 0.012 to 0.057, p = 0.003), and DB z scores by 0.019 units per month (95% CI: 0.011 to 0.028, p < 0.001). Patients with psychiatric comorbidities achieved the greatest improvements in TMT-B and DB z scores among all groups (0.0058 units/month, p = 0.036 and 0.028 units/month, p = 0.003, respectively). TMT-A z scores improved the most in patients taking 1-2 ASMs as well as in patients with psychiatric comorbidities (0.042 units/month, p = 0.002 and p = 0.003, respectively). Conclusion: Performance in all three tests improved at the group level during the follow-up period, with the most robust improvement observed in TMT-B, which requires inhibition control and set-switching in addition to the visuoperceptual processing speed that is crucial in TMT-A and working-memory performance that is essential in DB. Moreover, the improvement in TMT-B was further enhanced if the patient had psychiatric comorbidities.
RESUMO
Behavioural problems are not well recognized in multiple sclerosis (MS). In this review we aimed to evaluate the prevalence of behavioural symptoms and impairments in MS. A systematic search was carried out from MEDLINE, PsycINFO, Web of Science, CINAHL and COCHRANE. In total, 23 studies (1831 participants) were identified. Based on the literature search, behavioural symptoms and impairments are observed in MS. Aggression (23%), apathy (22%), euphoria (12%) and lack of insight (11%) were the most frequent symptoms, and adjustment disorder (17%) the most frequent impairment. Severe mental disorders are more infrequent than changes in behaviour, manner of reaction, and way of action. In conclusion the objective behavioural impairments and especially subjective symptoms are present in patients with MS. These manifestations should be taken into account in the diagnostics and treatment of the disease.

BACKGROUND: Depression, sleep disturbances, and cognitive difficulties impair the quality of life in people with multiple sclerosis (MS). Similar symptoms are also frequent during the menopausal transition. In clinical practice, it is important to consider the multifactorial causes of these overlapping symptoms and the potential benefits of menopausal hormone therapy (MHT). The objective of this study was to evaluate vasomotor symptoms (VMS), mood, sleep, and cognition of menopausal women with and without MS at baseline and during one year of MHT. METHODS: In this prospective baseline-controlled study, peri- and early postmenopausal participants with (n=14) and without (n=13) MS received MHT containing 1 or 2 mg of estradiol and cyclical 10 mg dydrogesterone for one year. VMS frequency, depressive symptoms (measured by Beck Depression Inventory), insomnia severity (Insomnia Severity Index), and cognitive performance (Paced Auditory Serial Addition Test; PASAT, Symbol Digit Modalities Test; SDMT) were evaluated at baseline and at 3 and 12 months of treatment. Differences in the outcome measures between groups at baseline were assessed using the Mann-Whitney U test. Changes during follow-up compared to baseline within groups were evaluated by Wilcoxon Signed Ranks Test. P < 0.05 was considered for statistical significance. MS activity was monitored by clinical assessment and brain MRI at baseline and at 12 months. RESULTS: Depressive symptoms were more common in MS group, while vasomotor and insomnia symptoms were equally common. During follow-up with MHT, VMS frequency decreased in both groups. Depressive symptoms decreased at 3 months (p = 0.031 with MS; p = 0.024 without MS) and the reduction was sustained at 12 months (p = 0.017; p = 0.042, respectively). Alleviation in insomnia symptoms was seen in participants without MS at 3 months (p = 0.029) and in those participants with MS suffering insomnia at baseline (p = 0.016 at 3 months; p = 0.047 at 12 months). Both groups improved their performance in PASAT, but no significant change was observed in SDMT. MS activity at baseline was mainly stable, and no increase in activity was detected during MHT. CONCLUSION: Improvements in vasomotor, depressive, and insomnia symptoms observed during one year of MHT are encouraging and suggest that larger placebo-controlled studies of MHT in women with MS are warranted. Cognitive implications were inconclusive because the findings in PASAT likely result from practice effect. MHT did not show any adverse effect on MS activity and increasing safety data will hopefully facilitate patient recruitment for future studies.

BACKGROUND: Cognitive deficits are a common manifestation in multiple sclerosis (MS) and have a wide effect on the patient's quality of life. Alleviation of the harmful effects caused by these deficits should be a major goal of MS research and practice. OBJECTIVES: The aim of this review was to evaluate the effects of neuropsychological/cognitive rehabilitation in MS by conducting a systematic review. SEARCH METHODS: A systematic literature search was carried out on reports drawn from Cochrane MS Group Specialised Register (To October 2010), Evidence-based medicine (EBM) reviews (To September 2010), MEDLINE (January 1950 to September 2010), EMBASE (1974 to September 2010), PsycINFO (January 1806 to September 2010), WEB OF SCIENCE (WOS) (January 1986 to September 2010), CINAHL (1982 to September 2010), and identified from the references in these reports. SELECTION CRITERIA: Randomised Controlled Trials (RCTs) and quasi-randomised trials evaluating the effects of neuropsychological rehabilitation in MS compared to other interventions or no intervention at all and employing neuropsychological rehabilitation methods and outcome measures were included. DATA COLLECTION AND ANALYSIS: Two review authors individually judged the relevance, risk of bias, and content of the included studies. Results were combined quantitatively with meta-analyses according to the intervention type: 1) Cognitive training and 2) Cognitive training combined with other neuropsychological rehabilitation methods. In addition, narrative presentation was used in reporting the results of those studies which were inappropriate to be included in the meta-analysis. MAIN RESULTS: Fourteen studies (770 MS patients) fulfilled the inclusion criteria. On the basis of these studies, low level evidence was found that neuropsychological rehabilitation reduces cognitive symptoms in MS. Cognitive training was found to improve memory span (standardised mean difference 0.54 (95% confidence interval 0.2 to 0.88, P = 0.002)), working memory (standardised mean difference 0.33 (95% confidence interval 0.09 to 0.57, P = 0.006)), and immediate visual memory (standardised mean difference 0.32 (95% confidence interval 0.04 to 0.6, P = 0.02)). There was no evidence of an effect of cognitive training combined with other neuropsychological rehabilitation methods on cognitive or emotional functions. The overall quality as well as the comparability of the included studies were relatively low due to methodological limitations and heterogeneity of outcome measures. Although most of the pooled results in the meta-analyses yielded no significant findings, twelve of the fourteen studies showed some evidence of positive effects when the studies were individually analysed. AUTHORS' CONCLUSIONS: The review indicates low level evidence for the positive effects of neuropsychological rehabilitation in MS. Interventions included in the review were heterogeneous. Consequently, clinical inferences can basically be drawn from single studies. Therefore, new trials may change the strength and direction of the evidence. To further strengthen the evidence, well-designed high quality studies are needed. In this systematic review, recommendations are given for improving the quality of future studies on the effects of neuropsychological rehabilitation in MS.

Cognitive deficits are common in multiple sclerosis (MS) occurring in over half of the patients. Deficits may have a multidimensional impact on patients' quality of life. The preliminary research evidence on the effectiveness of neuropsychological rehabilitation in MS so far is positive: rehabilitation may have favourable effects on patient's cognitive performance, mood, and fatigue symptoms. The patient's ability to manage with disease-related cognitive symptoms can be promoted by individually planned neuropsychological rehabilitation. In clinical work, the diagnostics and treatment of cognitive problems should be improved in patients with MS. Neuropsychological rehabilitation should be an important part of rehabilitation regimen in MS.

BACKGROUND: Deep brain stimulation (DBS) of the anterior nucleus of thalamus (ANT) is an emerging treatment option for patients suffering from refractory epilepsy. ANT has extensive connections with hippocampus and retrosplenial cingulum, areas associated mainly with spatial memory and with anterior cingulum which is important in executive functions. As refractory epilepsy is often associated with cognitive decline and neuronal damage, the decreased connectivity between ANT and remote structures might impact on the effects of DBS. OBJECTIVE: We hypothesized that the neuropsychological profile could reflect the connectivity of ANT and further predict the efficacy of ANT DBS. We evaluated the cognitive performance of patients with refractory epilepsy with DBS to evaluate whether neuropsychological profiles could reflect the connectivity of ANT and further predict the efficacy of ANT DBS. METHOD: Sixteen patients with refractory epilepsy treated with ANT DBS with at least 2 years of follow-up were included in the study. Patients underwent a neuropsychological evaluation as a part of the protocol and their clinical outcome was determined by seizure frequency in the last 6 months compared to baseline. The patients were classified as responders if there was a ≥50% reduction in the frequency of the predominant seizure type, otherwise as nonresponders. RESULTS: There were 12 responders and 4 nonresponders for ANT DBS treatment in the study population. Nonresponders performed worse than responders in neuropsychological tasks measuring executive functions and attention, such as the Trail-Making Test. CONCLUSION: Better executive functions and attention seemed to predict improved clinical outcome after the ANT DBS surgery. Based on our preliminary descriptive findings and the anatomical connectivity hypothesis, we suggest that deficits in executive functions may relate to an inferior outcome. This finding might offer new tools for refining the selection of patients with refractory epilepsy scheduled to undergo ANT DBS surgery. Moreover, it highlights the need for further investigations of neural connectivity in epilepsy.
RESUMO
Cognitive decline is recognized as a prevalent and debilitating symptom of multiple sclerosis (MS), especially deficits in episodic memory and processing speed. The field aims to (1) incorporate cognitive assessment into standard clinical care and clinical trials, (2) utilize state-of-the-art neuroimaging to more thoroughly understand neural bases of cognitive deficits, and (3) develop effective, evidence-based, clinically feasible interventions to prevent or treat cognitive dysfunction, which are lacking. There are obstacles to these goals. Our group of MS researchers and clinicians with varied expertise took stock of the current state of the field, and we identify several important practical and theoretical challenges, including key knowledge gaps and methodologic limitations related to (1) understanding and measurement of cognitive deficits, (2) neuroimaging of neural bases and correlates of deficits, and (3) development of effective treatments. This is not a comprehensive review of the extensive literature, but instead a statement of guidelines and priorities for the field. For instance, we provide recommendations for improving the scientific basis and methodologic rigor for cognitive rehabilitation research. Toward this end, we call for multidisciplinary collaborations toward development of biologically based theoretical models of cognition capable of empirical validation and evidence-based refinement, providing the scientific context for effective treatment discovery.

BACKGROUND: The Multiple Sclerosis Impact Scale-29 (MSIS-29) has been increasingly used to evaluate the self-perceived impact of multiple sclerosis (MS) on a patient. OBJECTIVES: The aim of this study was to evaluate the psychometric properties of the Finnish version of MSIS-29 in patients with MS. METHODS: A total of 553 patients with MS completed the MSIS-29 and self-administered questionnaires capturing information on demographics, disease characteristics and severity, perceived quality of life (EuroQol 5D-3L instrument), and fatigue (Fatigue Severity Scale). RESULTS: The data quality for MSIS-29 was excellent, with 99.5% computable scores for the MSIS-29 physical scale and 99.3% for the MSIS-29 psychological scale. Floor and ceiling effects were minimal. Excellent Cronbach's alpha values of 0.97 and 0.90 were seen for MSIS-29 physical and psychological subscales, respectively. The physical subscale showed highest correlations with measures of physical functioning, such as disease severity and the mobility domain of the quality of life. Similarly, the psychological subscale showed highest correlations with self-reported fatigue and the anxiety/depression domains of the quality of life. MSIS-29 physical scores related strongly to disease severity, whereas the MSIS-29 psychological scores increased in mild disease but declined in more severe disease forms. CONCLUSION: The Finnish version of MSIS-29 has satisfactory psychometric properties. Consistent with the previous recommendations, the use of two MSIS-29 subscale scores instead of a total score was supported.

BACKGROUND: Fatigue is one of the most debilitating symptoms in multiple sclerosis (MS) considerably interfering with patients' daily functioning. Both researchers and clinicians need psychometrically robust methods to evaluate fatigue in MS. OBJECTIVES: The objective of this study was (i) to evaluate the psychometric properties of the Finnish version of the Fatigue Severity Scale (FSS) and (ii) to describe the results among patients with MS. METHODS: In total, 553 patients with MS (mean age, 53.8 years; standard deviation [SD], 11.4; 79% women: mean patient-defined disease severity, Expanded Disability Status Scale [EDSS] 4.0, SD, 2.5) completed the self-administered questionnaires including the FSS. A standard procedure was used for the translation of the FSS. RESULTS: The mean (SD) score for the FSS was 4.5 (1.7); in 65% of the patients, the score was ≥4.0. The data quality of the FSS was excellent, with 99.6% of computable scale scores. Floor and ceiling effects were minimal. The FSS showed high internal consistency (Cronbach's alpha, 0.95). Unidimensionality was supported based on confirmatory factor analysis with the comparative fit index being 0.94. The FSS showed moderate/high correlations with the perceived burden of the disease, quality of life and disease severity, whereas, age or gender did not have a significant effect on the FSS score. CONCLUSIONS: The Finnish version of the FSS showed satisfactory reliability and validity and thus can be regarded as a feasible measure of self-reported fatigue.

This prospective longitudinal study reports recovery from mild traumatic brain injury (MTBI) across multiple domains in a carefully selected consecutive sample of 74 previously healthy adults. The patients with MTBI and 40 orthopedic controls (i.e., ankle injuries) completed assessments at 1, 6, and 12 months after injury. Outcome measures included cognition, post-concussion symptoms, depression, traumatic stress, quality of life, satisfaction with life, resilience, and return to work. Patients with MTBI reported more post-concussion symptoms and fatigue than the controls at the beginning of recovery, but by 6 months after injury, did not differ as a group from nonhead injury trauma controls on cognition, fatigue, or mental health, and by 12 months, their level of post-concussion symptoms and quality of life was similar to that of controls. Almost all (96%) patients with MTBI returned to work/normal activities (RTW) within the follow-up of 1 year. A subgroup of those with MTBIs and controls reported mild post-concussion-like symptoms at 1 year. A large percentage of the subgroup who had persistent symptoms had a modifiable psychological risk factor at 1 month (i.e., depression, traumatic stress, and/or low resilience), and at 6 months, they had greater post-concussion symptoms, fatigue, insomnia, traumatic stress, and depression, and worse quality of life. All of the control subjects who had mild post-concussion-like symptoms at 12 months also had a mental health problem (i.e., depression, traumatic stress, or both). This illustrates the importance of providing evidence-supported treatment and rehabilitation services early in the recovery period.

PURPOSE: The overall objective was to apply the goal attainment scaling (GAS) in neuropsychological rehabilitation in multiple sclerosis (MS). The specific aims were to evaluate whether (1) GAS-rated goals are attained; (2) attaining goals is related to standardized rehabilitation outcome measures; and (3) GAS-rated goals can be mapped to the International Classification of Functioning, Disability, and Health (ICF). METHOD: 56 relapsing-remitting MS patients received neuropsychological rehabilitation conducted once a week for 13 consecutive weeks. The attainment of GAS-rated personal goals and the association between achievement of goals and standardized rehabilitation outcome were evaluated. Moreover, GAS-rated goals were mapped to the ICF. RESULTS: Median (interquartile range) GAS attainment T-score was 56.0 (50.0-62.0); 88.8% of personal goals set were fully achieved. The attainment of goals was not significantly associated with the outcome in majority of the standardized measures. Of the 182 meaningful concepts identified in the goals, 181 could be mapped to the ICF. CONCLUSIONS: GAS seems to be an appropriate outcome measure in neuropsychological rehabilitation in MS. GAS-rated personal goals were well achieved, and GAS was found to tap changes not covered with standardized outcome measures. Implications for Rehabilitation GAS seems to be an appropriate outcome measure in neuropsychological rehabilitation in MS. GAS-rated personal goals were well achieved, and GAS was found to tap changes in the areas not covered with standardized outcome measures. GAS seems to offer a possibility to take into account the specific needs of each individual patient. The ICF can be used to classify goals in neuropsychological rehabilitation in MS.

Resilient individuals manifest adaptive behavior and are better able to recover from adversity. The association between resilience and outcome from mild traumatic brain injury (mTBI) is examined, and the reliability and validity of the Resilience Scale and its short form in mTBI research is evaluated. Patients with mTBI (n=74) and orthopedic controls (n=39) completed the Resilience Scale at one, six, and 12 months after injury. Additionally, self-reported post-concussion symptoms, fatigue, insomnia, pain, post-traumatic stress, and depression, as well as quality of life, were evaluated. The internal consistency of the Resilience Scale and the short form ranged from 0.91 to 0.93 for the mTBI group and from 0.86 to 0.95 for controls. The test-retest reliability ranged from 0.70 to 0.82. Patients with mTBI and moderate-to-high resilience reported significantly fewer post-concussion symptoms, less fatigue, insomnia, traumatic stress, and depressive symptoms, and better quality of life, than the patients with low resilience. No association between resilience and time to return to work was found. Resilience was associated with self-reported outcome from mTBI, and based on this preliminary study, can be reliably evaluated with Resilience Scale and its short form in those with mTBIs.

Cognitive deficits are common symptoms in multiple sclerosis (MS), and evident even in the early stages of the disease. Cognitive functions most frequently affected are information processing, memory and learning, and attention. Deficits may have a multidimensional impact on quality of life by weakening the ability to work, impairing social functioning and increasing the strain of the caregiver. To date, no effective pharmacological treatment for cognitive decline has been established, although there is some evidence suggesting that disease-modifying therapies may help to preserve cognitive function. Neuropsychological rehabilitation aims at alleviation of the negative effects of cognitive impairments and has been found to be effective in patients with stroke and traumatic brain injury. This paper discusses the evidence on neuropsychological rehabilitation in MS based on a recent systematic literature review and suggests a model for alleviating the effects of cognitive impairments in MS. The preliminary research evidence on the effects of neuropsychological rehabilitation in MS is positive: rehabilitation may have favorable effects on patients' cognitive performance and coping with cognitive impairments. In clinical practice, the diagnostics and treatment of cognitive impairments should be improved. Neuropsychological rehabilitation should be an important part of a rehabilitation regimen in MS.

BACKGROUND: The relationship between cognitive impairment and disease course and severity of multiple sclerosis (MS) is not well understood. OBJECTIVE: The aim of the study was to evaluate whether cognitive complaints in different clinical phenotypes and severity stages of MS are associated with differences in the profile of cognitive impairment. METHODS: 196 MS patients (relapsing-remitting RRMS n=138; secondary progressive SPMS n=32; primary progressive PPMS n=26) with perceived cognitive deficits underwent neuropsychological assessment with the brief repeatable battery of neuropsychological tests (BRBNT). Mood, impact of the disease, and quality of life were evaluated with self-reports. RESULTS: Only minor differences were observed in the cognitive impairment profile of different disease phenotypes and different disease severity stages. RRMS patients performed better only in one cognitive test of the BRBNT, than patients with progressive disease types. When RRMS, SPMS, and PPMS groups were evaluated separately, PPMS showed more pronounced cognitive impairments than RRMS and SPMS. The relationships between cognitive impairment and severity of disability as well as duration of disease were weak. CONCLUSION: MS patients with cognitive complaints tend to have a relatively similar cognitive impairment profile which is not dependent on the disease course and severity.
