• Study type: Interventional
• Enrollment: 64 (estimated)
• Sponsor: Hospital General Universitario Gregorio Marañon · Academic / Other
• Sex: All

Summary

The study will evaluate connectivity regardless whether patients present a clinical type that requires medical treatment. In this point, investigators will include patients with progressive evolution as well as initial forms of the disease (CIS) and properly established forms of multiple sclerosis (MS) in remittent-recidivant (RR) forms. The researches will not focus on medical treatment as some of these clinical forms have no indication for disease modifying drugs.

Detailed description

To date, no clear consensus has been reached related to default mode network (DMN) activity and different clinical types of MS. Due to this controversy on the literature regarding increment and decrement of DMN activity along the natural history of MS evolution, this study aim to add experimental information and more data that might help to disentangle this paradox, also correlating this DMN activity with anatomic and cognitive indexes. The investigators will also introduce a novel experimental design, including a prospective measure of the investigators connectivity and cognitive measures. In this study, investigators aim to evaluate connectivity regardless whether patients present a clinical type that requires medical treatment. In this point, patients with progressive evolution as well as initial forms of the disease (CIS) will be included and properly established forms of MS in RR forms. Researchers will not focus on medical treatment as some of these clinical forms have no indication for disease modifying drugs. Nevertheless, investigators consider that the study of connectivity is worth regardless their pharmacological treatment. The investigators also aim to offer data on the natural history of MS evolution for distinct MS type patients and healthy controls, as this study is planned to collect data longitudinally.
