Processing speed impairment in chronic inflammatory demyelinating polyneuropathy patients: a cross-sectional study.

Background: There is a lack of evidence of cognitive involvement in chronic inflammatory demyelinating polyneuropathy (CIDP) and, the reports about the involvement of the brain and central nervous system (CNS) are few and controversial. The Five Digit Test (FDT) evaluates processing speed (PS) and executive functions orally.

Objective: To evaluate the performance on the FDT of CIDP patients with and without CNS (brain/cerebellum) alterations observed on brain Magnetic Resonance Imaging (MRI) scans.

Cognitive Complaints Assessment and Neuropsychiatric Disorders After Mild COVID-19 Infection.

Objectives: This study aimed to analyze cognitive impairment associated with long-term coronavirus disease 2019 (COVID-19) syndrome and its correlation with anxiety, depression, and fatigue in patients infected with severe acute respiratory syndrome coronavirus.

Methods: This was a cross-sectional study of 127 patients with COVID-19. Tests to screen for neuropsychiatric symptoms included the Fatigue Severity Scale, Mini-Mental State Exam 2 (MMSE-2), Symbol Digit Modalities Test (SDMT), and Hospital Anxiety and Depression Scale.

Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS): discrete and regression-based norms for the Brazilian context.

Background: The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) has been recently developed as a brief, practical, and feasible tool for cognitive impairment in multiple sclerosis (MS).

Objective: This study aimed to provide continuous and discrete normative values for the BICAMS in the Brazilian context.

Methods: Normatization was achieved using six hundred and one healthy controls from the community assessed at five Brazilian geopolitical regions.

Anatomic and neuropsychological findings in low-educated cognitively intact elderly from a Brazilian cohort.

Unlabelled: In elderly individuals, low educational level may represent a risk factor for the development of dementia and a proxy of cognitive reserve.

Objective: This study examined the cognitive and neuroanatomic correlates of high versus low educational levels in cognitively healthy community-dwelling older adults in Brazil.

Methods: Fifty-three older adults (mean age: 68±5.

Normative values of the Brief Repeatable Battery of Neuropsychological Tests in a Brazilian population sample: discrete and regression-based norms.

Objective Cognitive dysfunction is common in multiple sclerosis. The Brief Repeatable Battery of Neuropsychological Tests (BRB-N) was developed to assess cognitive functions most-frequently impaired in multiple sclerosis. However, normative values are lacking in Brazil.

Correlation of clinical findings and brain volume data in multiple sclerosis.

Brain volume measurements are becoming an important tool for assessing success in controlling multiple sclerosis (MS) activity. MSmetrix (icometrix) is an easy-to-use platform, specific for MS magnetic resonance imaging (MRI) of the brain. It provides data on total brain volume, grey matter volume and lesion load volume.

Cross-cultural Adaptation, Reliability, and Validity of the BICAMS in Brazil.

Objective: To investigate the reliability and validity of a Brazilian-Portuguese adaptation of the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS).

Method: A Brazilian sample of 58 multiple sclerosis (MS) patients and 58 healthy controls (HC) were administered the Brazilian-Portuguese BICAMS test battery, comprising the Symbol Digit Modalities Test (SDMT), California Verbal Learning Test Second Edition (CVLT2), and the Brief Visuospatial Memory Test Revised (BVMTR). Mean differences between groups on BICAMS tests were assessed using analysis of covariance (ANCOVA), controlling for age, gender, education, anxiety, and depression.
