Text of the abstract

Rumination, i.e. the repetitive thinking about distress-related events, is an important risk factor in the development and maintenance of mental disorders, such as depression and anxiety, and is also related to the pathomechanism of chronic pain syndromes and migraine.
The aim of our study was to investigate rumination-related brain activation changes to pain with functional MRI (fMRI).
In the present study, we examined the brain activation changes with BOLD (blood oxygen level dependent) fMRI during perception of pain in 30 healthy subjects (18 women, mean age ± SD: 25.97 ± 4.04 years). For this reason, we used electric stimuli on the right hand of the participants, characterized by painful (VAS=7) and non-painful (VAS=3). All electric stimuli (n=30) were preceded by a visual cue, either pain cue or no pain cue. We assessed trait rumination with the 10-item Ruminative Response Scale (RRS).
Increased brain activation in several brain areas correlated positively with rumination scores regardless of preceding cues. Some of these areas are important parts of the pain processing network and therefore this phenomenon may be related to chronic pain states or migraine.
Our results suggest that highly ruminative individuals have an increased neural response to pain. In addition, this observation highlights the impact of cognitive psychotherapeutic approaches in managing pain syndromes and migraine.
