Study Summary

With this study, the investigators will substantiate if regional cerebral blood flow (CBF) is affected by tDCS, assess the amount of CBF change in relation to different currents, and measure differences in regional CBF under stimulation reactivity between healthy subjects and people with Multiple Sclerosis (PwMS)using Water O-15 PET (Water Oxygen-15 Positron EmissionTomography) imaging. The objective is to investigate the changes in regional CBF after transcranial direct current stimulation (tDCS) at different intensities (1 mA, 2 mA, 3 mA, 4 mA) in healthy subjects and PwMS. The design is a cross-sectional proof of principle study in 10 healthy subjects and 10 PwMS. Relative regional brain CBF (rCBF) will be analyzed semi-quantitatively using voxel-wise and region of interest-based approaches. Changes in CBF associated with tDCS-application will be calculated with a general linear model in a ramp function of the task-specific rCBF, according to previous work in our group using a glucose analogue. Exploratory statistical testing will be done using a paired samples t-test between task and rest conditions and unpaired t-tests between PwMS and healthy controls at the same intensities. With this study the investigators will be able to dose-dependently measure real-time rCBF changes after non-invasively stimulating the superficial parts of the dorsolateral prefrontal cortex (DLPFC), a commonly used target in therapeutic tDCS applications. This will provide further insight into whether tDCS is capable of inducing changes in rCBF.
