Cognitive deficits occur in children with multiple sclerosis. Comprehensive treatment planning should involve recognition that they may require academic accommodations for their education.

Fatigue and quality of life are significant concerns in adult multiple sclerosis (MS) but little is known about these factors in pediatric MS. The present investigation evaluates fatigue and quality of life in 51 pediatric MS patients to determine the rate of fatigue and reduced quality of life and assesses the relations between these variables and clinical factors. Fatigue and quality of life were assessed by self- and parent-report via the PedsQL Multidimensional Fatigue Scale and the PedsQL Quality of Life Scale. One-sample t-tests determined if scores were below published data for healthy individuals. Moreover, scores falling one standard deviation from norms were considered mildly affected, with severe difficulties being defined as scores falling two or more standard deviations from norms. Associations between self- and parent-reported difficulties and clinical factors were examined via Pearson correlation analyses. In comparison with healthy samples, pediatric MS patients reported greater difficulties with respect to fatigue, sleep, cognition, physical limitations, and academics. In addition to significant difficulties on these factors, parents reported problems with respect to emotional functioning, and tended to report greater fatigue, sleep, and cognitive difficulties than were self-reported. Expanded Disability Status Scale score was the only neurologic variable significantly related to fatigue or quality of life scores. Fatigue was significantly correlated with reports of sleep difficulties, cognitive problems, and quality of life variables. These findings suggest that fatigue and poorer quality of life is a clear concern in pediatric MS, and is related to overall physical disability.

Donepezil improved memory in MS patients with initial cognitive impairment in a single center clinical trial. A larger multicenter investigation of donepezil in MS is warranted in order to more definitively assess the efficacy of this intervention.

If a strong and stable association can be firmly established between cognitive and MR variables in appropriate subsets of MS patients, it might aid in the investigation of interventions to enhance cognition and modify the course of the disease.

Although Multiple Sclerosis (MS) occurring in childhood and adolescence has received increasing attention in recent years, the impact of the disease on cognitive function in this subgroup remains poorly understood. It has been posited that children and adolescents with MS may be particularly susceptible to cognitive dysfunction because the pathological processes, including inflammation, blood brain barrier breakdown, and demyelination, occur concurrently with ongoing myelination. Early work has documented that a number of these children present with cognitive deficits. However, there is no available information on the progression of these deficits, or on what clinical factors may predict further decline. The current article reviews what is currently known about pediatric MS and follows a cohort of pediatric MS patients and assesses cognitive function longitudinally. Participants were evaluated with a brief neuropsychological test battery on two separate occasions and correlational analyses assessed the relations between changes in cognition and several clinical variables including level of neurologic impairment, number of relapses prior to baseline assessment, number of interim relapses, age of disease onset, and disease length. The results indicate that a number of these patients experience further cognitive decline over time, or decline from previously normal functioning. Baseline level of neurologic disability was significantly correlated with changes in cognition. The number of interim relapses (i.e., relapses occurring between baseline assessment and re-evaluation) showed a modest relationship to changes in cognitive function, but this did not reach statistical significance.
