Articulation time does not affect speeded cognitive performance in multiple sclerosis.

Objective And Background: Cognitive test performance by individuals with multiple sclerosis (MS) may be biased because of MS-related speech problems. The purpose of this study was to compare articulation and pause durations between individuals with MS and controls on cognitive tests requiring an oral response.

Method: As part of a neuropsychological assessment, 41 patients with MS and 23 controls completed oral forms of 2 timed cognitive tests that are commonly used in MS.
