Sjogren's Syndrome (SS) is an autoimune disease of unknown etiology characterized by lymphocytic infiltration of the exocrine glands and other organs. patients usually presents with xerophthalmia, xerostomia, fatigue and other symptoms. Fatigue has often been reported as the biggest problem and the most difficult symptom patients have to deal with. Fatigue management in pSS is difficult. However, in other diseases such as Parkinson disease, post-polio syndrome and multiple sclerosis the use of Transcranial Direct Current Stimulation (tDCS) has recently been studied and has shown effectiveness. The overarching objective of this study is to examine the effect of a tDCS protocol in patients with pSS.

Interventionsart: Device

Interventionsname: Active Transcranial Direct Current Stimulation

Beschreibung: Subjects will undergo 5 sessions of tDCS of up to 2mA, at 20 minutes per session, 1x per day. During active stimulation, the current will be active for the full 20 minutes.

Armgruppenetikett: Active tDCS

Interventionsart: Device

Interventionsname: Sham Transcranial Direct Current Stimulation

Beschreibung: Subjects will undergo 5 sessions of tDCS, at 20 minutes per session, 1x per day. For sham tDCS, electrodes will be placed the same way as in the intervention group, for 20 minutes. However, the stimulator will deliver 2mA of current for only 30s. The current will not be active for the rest of the 20 minutes.

Armgruppenetikett: Sham tDCS
