The relation between self-reported cognitive dysfunction and neuropsychological performance over 24 weeks was assessed in a sample of 53 multiple sclerosis patients. Subjects were assessed at Weeks Zero and 24 as part of a clinical trial to enhance cognition. At baseline, subjects had at least mild cognitive impairment on the Rey Auditory Verbal Learning Test and an absence of depression. Neuropsychological performance was assessed with a modification of the well standardized Brief Repeatable Battery. The 5-item Perceived Deficits Questionnaire and a 2-item memory and attention/concentration questionnaire assessed self-perceived cognitive impairment. Self-assessed cognition did not correlate with neuropsychological performance at either baseline or 24 weeks. However, changes in the self-assessment measures did correlate with changes in neuropsychological performance. Patients accurately perceived some changes in their level of cognitive dysfunction, though they were insensitive to the degree of their current dysfunction. Possible explanations of this pattern of results are discussed

Fatigue is a significant factor in the lives of many MS patients and the most commonly reported symptom in many studies. Fatigue is an important symptom to consider because it affects patients' social lives, occupations, and activities of daily living. Efforts to predict fatigue have been mixed, but it appears to be related to overall quality of life and mood. From a pathophysiologic perspective, fatigue in MS is multifactorial and complex,involving dysregulation of the immune system, changes in the nervous system related to the disease process, neuroendocrine and neurotransmitter changes, and other factors such as physical deconditioning, sleep disturbance, pain, and medication side effects. Various attempts to assess fatigue have been made, and many measures are now available for use in clinical practice and research. In clinical practice, these measures help guide treatment considerations. Recent research has provided valuable strategies to ameliorate fatigue in MS, and although many patients continue to experience fatigue despite interventions, many receive substantial relief.Nonpharmacologic approaches-considered the first step in treatment-include exercise programs, cooling, dietary considerations, and energy conservation strategies. For patients who continue to experience significant fatigue, several medications (although not specifically approved for use in the reduction of MS-related fatigue) have proved effective in this regard.The first-line agents include amantadine for mild fatigue and modafinil for more severe cases. Second-line agents include pemoline and antidepressant medications. Other pharmacologic agents have also shown some promise

An increasing number of children and adolescents with multiple sclerosis (MS) are being identified and treated with disease-modifying therapies. Yet, there currently is little experience to guide clinicians. As more rapid diagnosis is made possible with magnetic resonance imaging, the number of pediatric MS patients requiring treatment will increase with time. This review draws on information from adult and pediatric neurology sources and summarizes current available data. Additional research is clearly needed. Nonetheless, there are several treatment principles: 1) establishing the diagnosis by differentiating MS from acute disseminated encephalomyelitis or recurrent acute disseminated encephalomyelitis; 2) emphasizing that there are parallels between adult and pediatric MS regarding the clinical presentation, disease course, and ability to tolerate therapy (the more extensive experience in adult MS can be applied to most pediatric cases); 3) explaining the importance of starting treatment early in the disease course and that these therapies seem well-tolerated in children; 4) providing reassurance that the family is not alone; as approximately 5% of the MS population has symptom onset before age 18 years (experience with pediatric MS is growing and centers with pediatric MS programs exist in other countries and are developing within the United States); and 5) reviewing symptom management and addressing issues such as academic performance that are unique to the pediatric MS subpopulation

OBJECTIVE: To examine cognitive functioning in children with multiple sclerosis (MS). METHODS: The authors examined the neuropsychological profile of 37 children with a diagnosis of clinically definite MS and assessed the associations between cognitive function and clinical features. RESULTS: Of 37 children and adolescents evaluated, 35% demonstrated significant cognitive impairment. Cognitive functioning was strongly related to several clinical variables, including current Expanded Disability Status Scale, total number of relapses, and total disease length. The consequences of MS adversely affected academic functioning in over a third of the children. CONCLUSIONS: Cognitive deficits occur in children with multiple sclerosis. Comprehensive treatment planning should involve recognition that they may require academic accommodations for their education
