Summary

Multiple sclerosis (MS) is a chronic inflammatory disease with around 200.000 patients in Germany. Besides physical symptoms, cognitive resources degrade over the years. Transcranial direct current stimulation (tDCS) is an established procedure to modulate cortical excitability in motor and cognitive functions. Therefore, tDCS may improve cognitive functions in patients with MS. Patients will work on a modified version of the symbol digits modalities test in two experimental sessions. During the task, they will receive either active stimulation or sham stimulation in a crossover design. Active stimulation is divided in anodal and cathodal stimulation. Anodal stimulation should facilitate cognitive processing; cathodal stimulation, on the other hand, should hinder cognitive processing.

Conditions

Interventions

DEVICE

Active transcranial direct current stimulation

A high-definition tDCS set-up will be used with a battery-driven stimulator (Starstim 8, Neuroelectrics). Active stimulation will be conducted with 1.5 milliampere (mA) with two electrodes using three reference electrodes for each active one for 20 minutes.

DEVICE

Sham transcranial direct current stimulation

A high-definition tDCS set-up will be used with a battery-driven stimulator (Starstim 8, Neuroelectrics). Sham stimulation will have a 40 seconds ramp-up and down. No stimulation will be applied after this 40 seconds.
