Behavioral Neurology of Multiple Sclerosis and Autoimmune Encephalopathies.

Multiple sclerosis (MS) is the most common nontraumatic cause of physical disability in young adults. Cognitive and neuropsychiatric problems are common in this disease independent of motor disability. Such problems especially in mild cases are ignored by physicians, although they may have a major impact on quality of life. Neurobehavioral changes may affect the adherence to treatment and worsen the ultimate prognosis. Although many studies have been performed in this regard, it seems that combining cognitive evaluations with other outcome measures in MS will enhance the understanding of neurobehavioral changes in MS.
