The relationship between executive functions and fluid intelligence in multiple sclerosis.

ABSTRACT:

Background & objective

Deficits in cognitive functions dependent upon the integrity of the prefrontal cortex have been described in Multiple Sclerosis (MS). In a series of studies we have shown that fluid intelligence (g) is a substantial contributor to frontal deficits and that, for some classical "executive" tasks, frontal deficits were entirely explained by g. However, for another group of frontal tasks deficits remained once g was introduced as a covariate. This second set of tests included multitasking and theory of mind tasks. In the present study, we aimed at determining the role of fluid intelligence in frontal deficits seen in patients with MS.

Methods

A group of patients with Relapsing Remitting MS (n = 36) and a group of control subjects (n = 42) were assessed wit
