Abstract
Research has recently focused on cognitive dysfunction in multiple sclerosis (MS). Cognitive deficits are frequently encountered in patients and account for important impairment in quality of life, therefore posing a major therapeutic challenge for the disease. We presently review studies on cognitive effects of pharmacological treatments in MS. There is evidence for a possible beneficial effect of immunomodulatory treatments, particularly of interferons, and also of acetylcholinesterase inhibitors on cognition in MS, which, however, requires evaluation in larger, multi-centre, longitudinal studies. Methodological issues and future prospects regarding the investigation of this issue are also discussed.
