Social cognition and executive functioning in multiple sclerosis: A cluster-analytic approach.

Multiple sclerosis (MS) is associated with deficits in social cognition, the process underlying social interaction and cognitive function. However, the relationships between executive impairment and social cognition remain unclear in MS. Previous studies exclusively focused on group comparisons between healthy controls and patients with MS, treating the latter as a homogeneous population.

Social Cognition Abilities in Patients With Different Multiple Sclerosis Subtypes.

Objectives: Multiple sclerosis (MS) can be associated with impaired social cognition. However, social cognition skills have never been explored in the different subtypes of MS. The first aim of this study was to examine whether MS subtypes differ on the course of social cognition.

Criteria improving multiple sclerosis diagnosis at the first MRI.

The introduction of the McDonald criteria has enabled earlier diagnosis of multiple sclerosis (MS). However, even with the 2010 revised criteria, nearly 50% of patients remain classified as "possible MS" following the first MRI. The present study aimed to demonstrate that time to MS diagnosis could be shorter than 2010 revised criteria, and established after a single early MRI in most patients with the association of the symptomatic lesion and at least one suggestive asymptomatic lesion.
