Background: Imaging can provide noninvasive neural markers of disease progression in multiple sclerosis (MS) that are related to behavioral and cognitive symptoms. Past work suggests that diffusion tensor imaging (DTI) provides a measure of white matter pathology, including demyelination and axonal counts. Objectives: In the current study, the authors investigate the relationship of DTI measures in the cingulum bundle to common deficits in MS, including episodic memory, working memory, and information processing speed. Methods: Fifty-seven patients with MS and 17 age- and education-matched controls underwent high-spatial resolution diffusion scans and cognitive testing. Probabilistic tracking was used to generate tracks from the posterior cingulate cortex to the entorhinal cortex. Results: Radial and axial diffusivity values were significantly different between patients and controls ( p < 0.031), and in patients bilateral diffusion measures were significantly related to measures of episodic memory and speed of processing ( p < 0.033). Conclusions: The tractography-based measures of posterior cingulum integrity reported here support further development of DTI as a viable measure of axonal integrity and cognitive function in patients with MS.

Nors susirgus išsėtine skleroze (IS) 40–70% žmonių sutrinka kognityvinis funkcionavimas, o depresija taip pat dažnai lydi IS (nustatoma 27–54% sergančiųjų), duomenys apie jų sąryšį gana prieštaringi. Straipsnyje analizuojamas kognityvinio funkcionavimo ir depresiškumo ryšys sergant išsėtine skleroze ir Trumpo daugiakarčio neuropsichologinių testų rinkinio (BRBNT) taikymo galimybės. Tyrime dalyvavo 41 žmogus, sergantis IS, ir 52 sveiki asmenys. Kognityvinėms funkcijoms vertinti buvo išversta ir naudojama BRBNT B versija (Rao and Peyser, 1986). Depresiškumui vertinti buvo taikomas Becko depresijos inventarijus (BDI-II). Gauti rezultatai rodo, jog sergančiųjų IS verbalinis išmokimas yra neigiamai susijęs su depresiškumu: depresiškumas statistiškai reikšmingai koreliuoja su pastovaus ilgalaikio atgaminimo rodikliais ir su ilgalaikiu atgaminimu po tam tikro uždelsimo laikotarpio, tačiau hipotezė, jog egzistuoja ryšys tarp informacijos apdorojimo greičio ir depresiškumo, nepasitvirtino. Klasifikuojant tiriamuosius į sveikus ir sergančius IS, gautas 100% BRBNT jautrumas, taip pat 100% specifiškumas.Pagrindiniai žodžiai: išsėtinė sklerozė, kognityvinis funkcionavimas, depresiškumas. THE RELATIONSHIP BETWEEN COGNITIVE FUNCTION AND DEPRESSION SEVERITY IN MULTIPLE SCLEROSIS PATIENTS: APPLICATION OF THE BRIEF REPEATABLE BATTERY OF NEUROPSYCHOLOGICAL TESTS (BRBNT) IN LITHUANIARamunė Grambaitė, Rūta Sargautytė SummaryMultiple sclerosis (MS) is an inflammatory and neurodegenerative disorder that affects primarily the cerebral white matter, thereby causing both physical and psychological disability. The purpose of this study was to investigate the possible relationship between cognitive function and depression severity in MS patients, as well as sensitivity and specificity characteristics of the BRBNT (The Brief Repeatable Battery of Neuropsychological Tests). We investigated 41 MS patients and 52 healthy people.Forty-one controls were selected from fifty-two healthy subjects and were individually matched with MS subjects for age, gender and education. BRBNT (Rao and Peyser, 1986) was designed for measuring verbal learning, visuospatial learning, sustained attention and concentration, information processing speed and verbal fluency cognitive functions. The B version of the BRBNT was translated and used in our study. Beck Depression Inventory-Second Edition (BDI-II) (Beck, 1996) was used for the evaluation of depression severity.Results of our study confirmed that depression severity was associated with verbal learning: Consistent Long Term Retrieval and the Delayed Recall significantly negatively related to depression severity. The relationship between information processing speed and depression severity was also negative, but not statistically significant. The five individual BRBNT tests separately did not significantly discriminate healthy controls from MS patients; however, when all the five BRBNT tests put together we found 100% sensitivity of and 100% specificity.Our findings lead to the conclusion that neuropsychological testing is important in organizing help strategies for MS patients. BRBNT is a sensitive measure of cognitive function in MS, and may assist with differential diagnosis. Similarly, BRBNT could well be applied to other groups of patients, whose illness results in physical and/or cognitive functional limitations.Keywords: multiple sclerosis, cognitive function, depression severity.

Background: The association between subjective cognitive fatigue and objective cognitive dysfunction in patients with multiple sclerosis (PwMS) has been studied, with conflicting results. Objective: To explore the impact of fatigue on cognitive function, while controlling for the influence of depression, disability, comorbidities, and psychotropic medications. Methods: PwMS completed a computerized cognitive testing battery with age- and education-adjusted cognitive domain scores. Disability (Expanded Disability Status Scale (EDSS)), cognitive fatigue, and depression were concurrently evaluated. Results: In all, 699 PwMS were included. Both cognitive fatigue and depression were significantly and negatively correlated with the same cognitive domains: information processing speed, executive function, attention, motor function, and memory (−0.15 ⩽ r ⩽ −0.14 for cognitive fatigue; −0.24 ⩽ r ⩽ −0.19 for depression). Multivariate analysis revealed significant but small independent correlations only between depression and neuropsychological test results, while cognitive fatigue had no independent correlation with objective cognitive function except for a trend toward impaired motor function in highly fatigued PwMS. Depression and cognitive fatigue accounted for no more than 6% of the variance in objective cognitive domain scores. Conclusion: Cognitive fatigue is not independently related to objective cognitive impairment. Depression may influence cognitive function of PwMS primarily when it is severe. Cognitive impairment in PwMS should not be ascribed to fatigue or mild depression.

Background: The protective effect of cognitive reserve (CR) on cognition in people with multiple sclerosis (PwMS) has been well described. Objective: To explore the relationship between aspects of CR, namely, leisure pursuits and depression. Methods: In a cross-sectional study, a sample of 155 PwMS and 115 healthy controls (HC) underwent cognitive testing with the Minimal Assessment of Cognitive Function in Multiple Sclerosis (MACFIMS) battery. Leisure activity was retrospectively recorded using the Leisure Activity Scale (LAS). Depression was assessed using the Hospital Anxiety and Depression Scale. Results: PwMS demonstrated greater decreases in leisure activity over time compared to the HC group, particularly in the past year ( p < 0.001). Here, depression accounted for 17% of the variance in determining the level of leisure activity ( p < 0.001). Premorbid IQ and leisure activity within the past year emerged as significant predictors of information processing speed, learning, memory and executive function. After controlling for depression, the influence of leisure activity on cognition was insignificant. Conclusion: Depression can cause significant changes in behaviour which can influence indices of CR, such as leisure pursuits. Successfully treating depression may lead to a more active lifestyle thereby offsetting in part the cognitive burden of disease.

Abstract Objective: Findings on the relationship of psychiatric symptoms with performance-based and self-reported cognitive function post-stroke are inconclusive. We aimed to (1) study the relation of depression and anxiety to performance-based cognitive function and (2) explore a broader spectrum of psychiatric symptoms and their association with performance-based versus self-reported cognitive function. Method: Individuals with supratentorial ischemic stroke performed neuropsychological examination 3 months after stroke. For primary analyses, composite scores for memory and attention/executive function were calculated based on selected neuropsychological tests, and the Hospital Anxiety and Depression Scale (HADS) was used. Psychiatric symptoms and self-reported cognitive function for secondary aims were assessed using the Symptom-Checklist-90 – Revised (SCL-90-R). Results: In a sample of 86 patients [mean (M) age: 64.6 ± 9.2; Mini-Mental State Examination (MMSE), 3–7 days post-stroke: M = 28.4 ± 1.7; National Institutes of Health Stroke Scale (NIHSS) after 3 months: M = 0.7 ± 1.6] depressive symptoms (HADS) were associated with poorer memory performance after controlling for age, sex, and education (p ≤ .01). In a subsample (n = 41; Age: M = 65.7 ± 8.1; MMSE: M = 28.4 ± 1.8; NIHSS: M = 1.0 ± 1.9), symptoms of phobic anxiety (SCL-90-R) were associated with poorer performance-based memory and attention/executive function, and symptoms of anxiety (SCL-90-R) with lower attention/executive function. Higher levels of self-reported cognitive difficulties were associated with higher scores in all psychiatric domains (p ≤ .05). Conclusion: Even in relatively well-functioning stroke patients, depressive symptoms are associated with poorer memory. The results also suggest that various psychiatric symptoms are more related to self-reported rather than to performance-based cognitive function. Screening for self-reported cognitive difficulties may not only help to identify patients with cognitive impairment, but also those who need psychological treatment.

Cognitive impairment in multiple sclerosis is difficult to study because of the heterogeneity and variability of this disease. The gold standard for measurement of cognitive function in multiple sclerosis is a full battery of neurocognitive tests, which is time consuming and expensive. Some cognitive tests like the PASAT, a measure of working verbal memory and processing speed, have been proposed for screening and follow-up of cognitive function in clinical trials. We studied whether we could measure cognitive function in multiple sclerosis over the Internet. For this we used the Cognitive Stability Index (CSI)™, developed for persons with known or suspected primary central nervous system illness. The CSI was compared with formal neurocognitive testing (NPsych) and the PASAT in a cross-sectional study of 40 consecutive multiple sclerosis patients with subjective cognitive complaints. NPsych revealed that only 18 of the 40 patients (46%) were cognitively impaired. Although both the CSI and the PASAT were equalivalent in their specificity (86%), the CSI was significantly more sensitive than the PASAT (83% versus 28%). We conclude that the CSI, because of its availability over the Internet, has great potential as a tool for screening and follow up of cognitive function in multiple sclerosis.

Purpose Dysarthria is a consequence of multiple sclerosis (MS) that can co-occur with cognitive impairment. Clinical management thus requires understanding the separate and combined effects of dysarthria and cognitive impairment on functional communication in MS. This study compared perceptual measures of intelligibility and speech severity that capture functional communication deficits for 4 operationally defined groups with MS. The relationship between communication participation and perceptual measures was also examined. Method Forty-eight adults with MS and 12 healthy controls participated. Cognitive testing and dysarthria diagnosis determined group assignment: (a) MS with cognitive impairment (MSCI), (b) MS with a diagnosis of dysarthria and no cognitive impairment (MSDYS), (c) MS with dysarthria and cognitive impairment (MSDYS + CI), and (d) MS without dysarthria or cognitive impairment (MS). Sentence Intelligibility Test scores, scaled speech severity obtained from the “Grandfather Passage,” and Communication Participation Item Bank (CPIB) scores were analyzed. Results Sentence Intelligibility Test scores approached 100% for all groups. Speech severity was greater for the MSDYS + CI and MSDYS groups versus controls. CPIB scores were greatest for the MSDYS + CI group and were not significantly correlated with either perceptual measure. Conclusions The CPIB and speech severity were sensitive to aspects of communication problems for some groups with MS not reflected in a measure of sentence intelligibility. Findings suggest the importance of employing a variety of measures to capture functional communication problems experienced by persons with MS.
