Association Between Functional Changes in the Brain and the Perception of Pain in Patients With Inflammatory Bowel Diseases (IBD) - Measured With Functional Magnetic Resonance Imaging.

Assoziation Zwischen Funktionellen Gehirnveränderungen Und Der Schmerzwahrnehmung Bei Patienten Mit Chronisch entzündlicher Darmerkrankung Mittels fMRT

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 functional magnetic resonance imaging (fMRI) 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 fMRI.

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 functional magnetic resonance imaging (fMRI)
• Pregnancy
• Sever internal or psychiatric condition
