Abstract
BACKGROUND Executive dysfunction occurs in 15% to 20% of multiple sclerosis (MS) patients and verbal fluency tests are frequently used to assess this deficit. The Word List Generation (WLG) is one of the most used measures in MS. This study aims to compare the performance of WLG of MS patients and healthy controls and to analyze the influence of clinical and demographic factors on the performance of MS patients. METHODS One hundred and nine MS patients and an age- and gender-matched group of 138 healthy controls were evaluated with WLG Portuguese version, as well as other tests from the Brief Repeatable Battery of Neuropsychological Tests (BRBN-T), subtests from WAIS, a phonemic fluency test (M, R, and P), and measures of psychological symptomatology and cognitive fatigue. The MS group (70.6% females) was mainly diagnosed with RRMS (89.2%). RESULTS The MS group performed significantly lower than healthy controls on the WLG. In the MS group, this performance was significantly correlated with the level of education. Significant differences were found between the two groups regarding cognitive fatigue, with MS patients reporting higher levels than healthy controls. However, this variable was not related to the performance on the WLG for MS patients. CONCLUSIONS This study suggests that MS is associated with large levels of cognitive decline on the phonemic verbal fluency tests. These results are consistent with other studies and highlight the importance of verbal fluency and cognitive speed measures in the neuropsychological assessment of MS. Deficits on this task seem to be highly related to the level of education of the patient rather than other demographic and clinical factors.

Abstract
BACKGROUND Peak width of Skeletonized Mean Diffusivity (PSMD), as a novel marker of white matter (WM) microstructure damage, is associated with cognitive decline in several WM pathologies (i.e., small vessel disorders). We hypothesized that markers combining alterations in whole WM could be associated with cognitive dysfunction in relapsing-remitting multiple sclerosis (RRMS) patients. METHODS We used PSMD based on tract-based spatial statistics (TBSS) of diffusion tensor imaging (DTI) magnetic resonance (MR) scans. We investigated RRMS patients (n = 73) undergoing interferon beta (IFN-β) therapy. In this cross-sectional study, we investigated the association between neuropsychological data and clinical and MRI variables: PSMD, WM hypointensities, and normalized brain volume (NBV). RESULTS In our cohort, 37 (50.7%) patients were recognized as cognitively impaired (CI) and 36 (49.3%) patients were cognitively normal (CN). In regression analysis, PSMD was a statistically significant contributor in the California Verbal Learning Test (CVLT) list A (p = 0.04) and semantic fluency (p = 0.036). PSMD (p < 0.001, r2 = 0.35), NBV (p = 0.002, r2 = 2.6) and WM hypointensities (p < 0.001, r2 = 0.40) were major contributors to upper extremity disability (9HPT) in the CN subgroup. A significant contributor in the majority of neuropsychological measures was education attainment. CONCLUSION We investigated PSMD as a new parameter of WM microstructure damage that is a contributor in complex cognitive tasks, CVLT performance, and semantic fluency. PSMD was a statistically significant contributor to upper extremity disability (9HPT) together with WM hypointensities and NBV. Education attainment proved to be relevant in the majority of cognitive domains. Further studies are needed to estimate PSMD relevance as a marker of CI in MS.

Abstract
BACKGROUND Clinical symptoms of multiple sclerosis (MS) are variable and may include cognitive impairment, which can be assessed with the verbal fluency test (VFT). This test is evaluated by counting words spoken during a 2-min period, which is not a functional approach. OBJECTIVE The objectives of this observational study were to: (1) determine new parameters that reflect communication and cognitive functions in persons with multiple sclerosis (PwMS) considering the evaluation of real-time word production in the VFT; (2) compare the results with those of a control group; and (3) evaluate the impact of including errors. METHODS A phonological fluency test ("letter P") and a semantic fluency test ("animals") were used. The real-time word production was recorded. The main variables studied were the total number of words, first word delay, moment of inflection of the curve corresponding to the change in the cognitive process, speed of word production before inflection, and maximum delay between 2 consecutive words. These variables were studied by taking into account or not errors. RESULTS We included 68 PwMS and 33 healthy controls. VFT results were impaired in PwMS. The total number of words, first word delay, speed before inflection, and maximum delay were relevant to the study of phonologic fluency. For studying semantic fluency, the total number of words, first word delay, speed before inflection, and inflection time of the curve seemed relevant. Taking into account errors was significant only for total number of words. CONCLUSION Taking into account errors in evaluating real-time word production in PwMS is of interest only for the total number of words performed but has no impact on the variables studied. These variables should be used to quantitatively evaluate verbal fluency with the objective of evaluating functionally relevant parameters (communication).

Abstract
Verbal fluency refers to the ability to generate words quickly and efficiently according to predefined phonological or semantic criteria. Deficits in verbal fluency limit patients' ability to communicate effectively and to function well in social setups. Multiple sclerosis (MS) patients suffer from various cognitive impairments, and some of them experience language deficits as well. The goal of this study is to examine the contribution of the dorsal and ventral language pathways to verbal fluency in MS patients. All patients (N = 33) underwent diffusion MRI (dMRI) and fluency measurements. Diffusion parameters were calculated along dorsal and ventral language-related pathways and their right-hemispheric homologs, identified individually in each patient. Significant correlations were found between fluency measures and mean fractional anisotropy (FA) in several pathways, including the left fronto-temporal arcuate fasciculus (AFft), bilateral inferior fronto-occipital fasciculus (IFOF), and bilateral frontal aslant tract. Along-tract correlations revealed a more selective pattern of associations: letter-based fluency was associated with FA in a segment of the left AFft (dorsal pathway), while category-based fluency was associated with FA in a segment of the right IFOF (ventral pathway). The observed pattern of associations, mapping letter-based fluency to the dorsal stream and category-based fluency to the ventral stream, fits well within the dual stream framework of language processing. Further studies will be necessary to assess whether these associations generalize to the typical adult population or whether they are tied to the clinical state.

Abstract
Cognitive and neuropsychiatric disorders in patients with multiple sclerosis have been extensively documented. The focus of this review will be on cognitive and neuropsychiatric disorders in multiple sclerosis patients from Latin America, in the context of international literature. Multicentre studies carried out in Latin America have shown that 43% of the patients have cognitive impairment and 34.5% in early stages of the disease, 29% depression and 20.9% neuropsychiatric disorders. The profile of cognitive impairment corresponds to alterations in visual and verbal memory, in attention, in information processing speed and in verbal fluency. The neuropsychiatric profile showed disorders in anxiety, depression, apathy and irritability domains. In the region, there exist validations of the multiple sclerosis neuropsychological screening questionnaire (MSNQ), the brief repeatable battery of neuropsychological tests (BRB-N) and the brief international cognitive assessment for multiple sclerosis (BICAMS), as well as of the paced auditory serial addition test (PASAT) and the symbol digit modalities test (SDMT). A study showed that 53% of the patients who met the NEDA3 condition had cognitive impairment. This finding highlights the need for taking cognitive assessment into account when determining therapeutic efficacy.

Abstract
This article describes some prevalent personality dimensions of recently diagnosed multiple sclerosis patients. A sample of 33 female recently diagnosed with relapsing-remitting multiple sclerosis (RRMS) was assessed with the NEO-FFI personality scale. Beck depression (BDI) and anxiety (BAI) scales were also used. No significant levels of anxiety or depression were identified in this group. As for personality factors, conscientiousness was the most common factor found, whereas openness to experience was the least observed. Literature on the relationship between personality and MS is scarce and there are no Brazilian studies on this subject. Some personality traits might complicate or facilitate the experience of living with a chronic, disabling and uncertain neurological condition such as MS.

Abstract
UNLABELLED Multiple sclerosis (MS) is a neurodegenerative disease characterised by inflammation and demyelination. It generates irreversible myelin changes, which in turn give rise to physical and cognitive disorders. The verbal fluency test (VF) has been shown to be a sensitive tool for detecting cognitive impairment in these patients. OBJECTIVE To compare quantitative and qualitative aspects of performance on semantic and phonological fluency tests between MS patients and healthy controls by analysing total words produced and strategies used (clusters and switching). METHOD We evaluated 46 patients with MS and 33 healthy controls using the VF test. RESULTS The semantic VF task revealed no significant differences between groups; for the phonological task, patients demonstrated reduced word production (F [77]=2.286 P<.001) and poorer use of grouping strategies, resulting in more frequent switching (F [77]=3.808 P<.005). CONCLUSIONS These results support using qualitative analysis for recall strategies, since the technique provides data about which components of the task are affected by brain damage. Clusters depend on the integrity of semantic memory, while switching has to do with developing effective search strategies, cognitive flexibility, and the ability to modify responses. Frontal lobe damage has been reported in MS, and this is consistent with results from the phonological VF test.

Abstract
Background The number of multiple sclerosis (MS) information websites, online communities, and Web-based health education programs has been increasing. However, MS patients’ willingness to use new ways of communication, such as websites, mobile phone application, short message service, or email with their physician, remains unknown. Objectives We designed a questionnaire to evaluate the a priori use of electronic communication methods by MS patients and to assess their acceptance of such tools for communication with their health care providers. Methods We received complete data from 586 MS patients aged between 17 and 73 years. Respondents were surveyed in outpatient clinics across Germany using a novel paper-and-pencil questionnaire. In addition to demographics, the survey items queried frequency of use of, familiarity with, and comfort with using computers, websites, email, and mobile phones. Results About 90% of all MS patients used a personal computer (534/586) and the Internet (527/586) at least once a week, 87.0% (510/586) communicated by email, and 85.6% (488/570) communicated by mobile phone. When asked about their comfort with using electronic communication methods for communication with health care providers, 20.5% (120/586) accepted communication by mobile Internet application or short message service via mobile phone, 41.0% (240/586) by websites, 54.3% (318/586) by email service, and 67.8% (397/586) by at least one type of electronic communication. The level of a priori use was the best predictor for the acceptance of electronic communication with health care providers. Patients who reported already searching online for health information (odds ratio 2.4, P < .001) and who had already communicated with a physician through a website (odds ratio 3.3, P = .03) reported higher acceptance for Web-based communication. Patients who already scheduled appointments with their mobile phones (odds ratio 2.1, P = .002) were more likely to accept the use of mobile phone applications or short message service for communicating with their physician. Conclusions The majority of MS patients seen at specialist centers already use modern communication technology regularly. New forms of electronic communication appear to have high levels of acceptance for exchanging information about MS between patients and health care providers. Such methods should be integrated into eHealth services such as electronic health records and patient relationship management systems.

Abstract
Investigations on the prevalence rates of multiple sclerosis (MS) around the world have yielded important clues on the interplay between genetic susceptibility and environmental factors. As Brazil is a huge country laid on many latitudes and inhabited by population with distinct ethnic backgrounds, it might be assumed that the frequency of MS varies in its different regions. Objective: To determine the prevalence rate of MS in Belo Horizonte, the capital of the State of Minas Gerais, Southeastern Brazil. Methods: We used six sources to draw up a provisional list of identified cases of MS. Only patients with diagnosis of clinically definite MS according to Poser Committee criteria were included. Results: The calculated crude MS prevalence was 18.1/100,000 inhabitants. Conclusions: The MS prevalence in Belo Horizonte is similar to that found in São Paulo and Botucatu, two other cities in southeastern Brazil with similar ethnic background.

Abstract
Cognitive impairment is a symptom of multiple sclerosis (MS). Different clinical forms of multiple sclerosis have different cognitive profiles, according to findings of previous studies which used extensive batteries of neuropsychological tests. OBJECTIVE: To investigate cognitive profiles of Brazilian patients with relapsing-remitting multiple sclerosis (RRMS) and primary progressive multiple sclerosis (PPMS) by using a brief battery of neuropsychological tests. METHOD: Sixty-six patients, within 18-65 of age and 3-18 years of education, were paired with healthy control subjects, regarding gender, age, and education level. RESULTS: On Symbol Digit Modalities Test and Hooper Visual Organization Test, cognition was affected in 50% in RRMS and 69% in PPMS. Fluency of "F" was impaired in 24% of RRMS and 81% of PPMS. Immediate recall was affected in 32% of RRMS and in 63% of PPMS; whereas late recall, in 46% of relapsing-remitting and in 69% of primary progressive. CONCLUSION: Cognitive profiles of relapsing-remitting and primary progressive patients are different

Abstract
Objetivo: O objetivo deste estudo é investigar o perfil neuropsicológico de uma amostra de pacientes brasileiros com esclerose múltipla surto-remissão (EMSR), descrevendo as funções cognitivas mais comprometidas. Métodos: Cinquenta e quatro pacientes com EMSR e 54 controles pareados por sexo, idade e nível educacional foram avaliados por meio de uma longa e abrangente bateria neuropsicológica. Resultados: Observou-se que 59,2% dos pacientes com EMSR apresentaram algum tipo de comprometimento cognitivo em comparação com o grupo controle. Os testes neuropsicológicos identificaram disfunções executivas, da memória de longo prazo e da velocidade de processamento de informação. Conclusão: Os resultados encontram-se em conformidade com estudos anteriores relatados na literatura internacional. Contudo, mais estudos ainda são necessários para uma estimativa maior do perfil das alterações cognitivas da esclerose múltipla no Brasil.
