Experience in cognitive assessment in MS relevant to developing a simple rating system.

Cognitive involvement in multiple sclerosis has not been given adequate clinical attention. Many patients have behavioral problems which may be ascribed superficially to depression or inability to cope. Cognitive assessment as conducted in most neurological examinations may be rated as normal. However, neuropsychological testing on these patients frequently reveals impairment of cognition. These findings merit followup to provide clearer directives for clinical interventions.
