Association of Functional Changes in the Brain and the Perception of Pain in Patients With Chronic Inflammatory Bowel Diseases (IBD)

In the study the investigators aim to test whether transcranial direct current stimulation (tDCS)-induced pain reduction is in association with functional changes in the brain measured with magnetic resonance imaging (MRI) in patients with chronic inflammatory bowel diseases (IBD).

Hypothesis: Transcranial direct current stimulation can reduce the perception of pain in patients with chronic inflammatory bowel diseases, which is in association with changes in the brain measured via MRI.

Inclusion Criteria:

• Inflammatory bowel disease
• Chronic pain (more than 3 months)
• Pain (VAS > 3/10)

Exclusion Criteria:

• Contraindication to transcranial direct current stimulation
• Contraindications to magnetic resonance imaging (MRI)
• Pregnancy
• Sever internal or psychiatric condition
