Abstract
BACKGROUND Cognitive impairment is observed in 43-70 % of Multiple sclerosis (MS) patients. One of the most widely used batteries for cognitive assessment in this population is the Brief International Cognitive Assessment for MS (BICAMS). The objective of this study was to validate and assess the reliability of the BICAMS in a Mexican population with MS and to obtain and provide regression-based norms. METHODS One hundred healthy controls (HCs) and 100 patients with multiple sclerosis participated in the present study, and groups were matched for age, years of education and sex. Subjects completed all three tests of the BICAMS. Test-retest measures were obtained from 30 patients to test reliability. RESULTS The sample´s average age was 43.39 ± 6.03 years old, and the average years of education was 12.55 ± 2.52 years. Approximately 63 % of the participants were female. The groups did not differ in age, years of education, or sex. The MS group performed significantly worse than the HCs group on all three neuropsychological tests. A significant difference was observed for the SDMT (t = 10.166; p=<0.001), CVLT-II (t = 10.949; p=<0.001), and BVMT-R (t = 2.636; p = 0.009). For all comparisons, the effect size (d) for each test was calculated as follows: SDMT= 0.58 and CVLT-II= 0.61. The test-retest coefficients for each test were as follows: SDMT: r = 0.95; CVLT-II: r = 0.84; and BVMT-R = 0.81. CONCLUSION The BICAMS can provide information on cognitive impairment in MS patients, and this information can be used by neuropsychologists for cognitive rehabilitation in different domains.

A Systematic Review and Meta-Analysis of the Brief Cognitive Assessment for Multiple Sclerosis (BICAMS) International Validations. J Clin Med 2023; 12:jcm12020703. [PMID: 36675637 PMCID: PMC9863826 DOI: 10.3390/jcm12020703] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 01/03/2023] [Accepted: 01/09/2023] [Indexed: 01/17/2023] Open
Abstract
Cognitive impairment is a prevalent and debilitating symptom of multiple sclerosis (MS) but is not routinely addressed in clinical care. The Brief Cognitive Assessment for Multiple Sclerosis (BICAMS) was developed in 2012 to screen and monitor MS patients’ cognition. This systematic review and meta-analysis aimed to identify, synthesise, and critically appraise current BICAMS’ international validations. The literature search was conducted using PubMed, PsycINFO and Web of Science electronic databases in August 2022. Quantitative, peer-reviewed adult studies, which followed the BICAMS international validation protocol and were published in English, were included. The search identified a total of 203 studies, of which 26 were eligible for inclusion. These reported a total of 2833 adults with MS and 2382 healthy controls (HC). The meta-analysis showed that BICAMS identified impaired cognitive functioning in adults with MS compared to HC for all three subtests: information processing speed (g = 0.854, 95% CI = 0.765, 0.944, p < 0.001), immediate verbal recall (g = 0.566, 95% CI = 0.459, 0.673, p < 0.001) and immediate visual recall (g = 0.566, 95% CI = 0.487, 0.645, p < 0.001). Recruitment sites and strategies limit the generalisability of results. BICAMS is a valid and feasible international MS cognitive assessment.

Neuroimage Clin 2022; 34:103033. [PMID: 35561552 PMCID: PMC9112031 DOI: 10.1016/j.nicl.2022.103033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 05/01/2022] [Accepted: 05/03/2022] [Indexed: 11/16/2022]
Abstract
Performance in episodic past, future or counterfactual thinking in relapsing-remitting MS and controls was explored. Behavioral and diffusion weighted imaging were used to evaluate associations between white matter integrity and group differences in performance. Relative to controls, MS patients showed reductions in episodic details across all three simulations. Reduced white matter integrity in three association tracts predicted this reduction in episodic details during counterfactual simulations.
Multiple sclerosis (MS) is a progressive disease characterized by widespread white matter lesions in the brain and spinal cord. In addition to well-characterized motor deficits, MS results in cognitive impairments in several domains, notably in episodic autobiographical memory. Recent studies have also revealed that patients with MS exhibit deficits in episodic future thinking, i.e., our capacity to imagine possible events that may occur in our personal future. Both episodic memory and episodic future thinking have been shown to share cognitive and neural mechanisms with a related kind of hypothetical simulation known as episodic counterfactual thinking: our capacity to imagine alternative ways in which past personal events could have occurred but did not. However, the extent to which episodic counterfactual thinking is affected in MS is still unknown. The current study sought to explore this issue by comparing performance in mental simulation tasks involving either past, future or counterfactual thoughts in relapsing-remitting MS. Diffusion weighted imaging (DWI) measures were also extracted to determine whether changes in structural pathways connecting the brain’s default mode network (DMN) would be associated with group differences in task performance. Relative to controls, patients showed marked reductions in the number of internal details across all mental simulations, but no differences in the number of external and semantic-based details. It was also found that, relative to controls, patients with relapsing-remitting MS reported reduced composition ratings for episodic simulations depicting counterfactual events, but not so for actual past or possible future episodes. Additionally, three DWI measures of white matter integrity—fractional anisotropy, radial diffusivity and streamline counts—showed reliable differences between patients with relapsing-remitting MS and matched healthy controls. Importantly, DWI measures associated with reduced white matter integrity in three association tracts on the DMN—the right superior longitudinal fasciculus, the left hippocampal portion of the cingulum and the left inferior longitudinal fasciculus—predicted reductions in the number of internal details during episodic counterfactual simulations. Taken together, these results help to illuminate impairments in episodic simulation in relapsing-remitting MS and show, for the first time, a differential association between white matter integrity and deficits in episodic counterfactual thinking in individuals with relapsing-remitting MS.

Information Processing Speed Assessed with Letter Digit Substitution Test in Croatian Sample of Multiple Sclerosis Patients. Diagnostics (Basel) 2022; 12:diagnostics12010111. [PMID: 35054278 PMCID: PMC8774378 DOI: 10.3390/diagnostics12010111] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 12/29/2021] [Accepted: 12/30/2021] [Indexed: 12/12/2022] Open
Abstract
Cognitive impairment is a common complaint in people with multiple sclerosis (pwMS). The study objective was to determine the psychometric properties of the letter digit substitution test (LDST) that measures information processing speed and to investigate the impact of relevant predictors of LDST achievement in pwMS. The design was cross-sectional. The study included 87 pwMS and 154 control subjects. The validity of LDST was examined, and a hierarchical regression model was used to explore relevant predictors of LDST success. The LDST had excellent construct validity, as expressed by differences between pwMS and control subjects. Convergent validity of the LDST was supported by a significant moderate correlation with the expanded disability status scale (EDSS) (ρ = −0.36; p < 0.05) and a significantly strong correlation with the multiple sclerosis impact scale (MSIS-29) physical subscale (r = −0.64; p < 0.01). The LDTS score well differentiated the pwMS considering age, education, EDSS, disease duration, comorbidity, and medication therapy. Using the LDST as a criterion variable in pwMS results showed consistent evidence for the age, education, and EDSS impact on LDST performance. The best cut-off score of ≤35 discriminated the control and MS group. LDST proved to be a valid test for assessing information processing speed in pwMS.

Tunisian version of the brief international cognitive assessment for multiple sclerosis: Validation and normative values. Mult Scler Relat Disord 2021; 58:103444. [PMID: 34929452 DOI: 10.1016/j.msard.2021.103444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 11/30/2021] [Accepted: 12/01/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND The Brief International cognitive assessment for Multiple sclerosis (BICAMS) is a specific batterie used to identify cognitive impairment in Multiple Sclerosis (MS) in a reliable and easy way. To date, for the Arabic-speaking Tunisian MS patients, there is no consensus for the use of specific cognitive batteries in MS. OBJECTIVE The aim of our work was to develop and validate the Tunisian version of the BICAMS (T-BICAMS) and to determine our own normative values. MATERIAL AND METHODS Patients diagnosed with MS and followed up in the department of Neurology of Razi Hospital were recruited and matched to healthy controls according to age, sex and educational level. T-BICAMS validity was established by comparing MS and healthy controls for symbol digit modalities test (SDMT), brief visual memory test (BVMT-R) and Tunisian verbal learning tests (TVLT) which was used instead of the California verbal learning test (CVLT-II). RESULTS The 104 MS patients and 104 healthy controls were comparable for age, sex and educational level. The MS group exhibited lower performances in all T-BICAMS domains compared to healthy controls: SDMT (x003Dp<10-3), BVMT-R (p = 0.002) and TVLT (p x003D<10-3). T-BICAMS Cronbach alpha value was 0.741. Normative values were identified for patients with MS: SDMT [39-40], BVMT-R [26-27] and TVLT [43-44]. Cognitive impairment was identified among 76 patients (73.1%). Males, lower educational levels and progressive MS were associated with a more severe cognitive impairment. CONCLUSIONS The current study has established the BICAMS as a valid and reliable tool for the identification of cognitive impairment in the Tunisian MS population.
