TMT, COWAT, Boston Naming Test, CELF 3rd edition, WRAML, WMI
5/12 (cognitive decline assessed using the criteria of more tests showing impaired at the time of the 2nd test than at the baseline) 7/12 (cognitive decline assessed using the criteria of decline in z-score composite from the baseline to the time of the 2nd test)
Rate of impairment was 37% at baseline and 33% at follow-up Most participants showed no change while (6%) declined on two or more tasks and (9%) improved on 2 or more tasks
Visuomotor integration, information processing speed, attention
Neuropsychological evaluations were conducted at baseline and up to four more assessments, with each evaluation separated by a minimum of 1 year.
SDMT, TMT, WASI, WISC-III
This study examined changes in cognitive maturation in a cohort of pediatric-onset MS patients as a function of age at disease onset and cognitive reserve factors (baseline IQ and parental social status) Younger age at disease onset was associated with a greater likelihood of cognitive decline on both the TMT-B () and SDMT ()
Younger age at disease-onset increases the vulnerability for disrupted performance on measures of information processing, visual scanning, perceptual/motor speed, and working memory
WASI, Visual Matching from the WJ Tests of Cognitive Abilities, TMT A-B, SDMT, Conner’s Continuous Performance Test (5th edition)–number of omission errors, Vocabulary and Similarities subtests of the WASI, WJ Tests of Achievement, Verbal Fluency Test from DKEFS, VMI, Block Design and Matrix Reasoning subtests from the WASI, TOMAL-2, WSR, Grooved Pegboard test
Improving: 18% in MS group, 86% in control group The RCI method results showed that the majority of patients remained stable or improved over time (21 of 28; 75%), with only seven of 28 patients (25%) demonstrating decline on three or more of the neuropsychological tests. Only 1 of 26 controls (3.8%) showed cognitive deterioration ().
