Do positive expectations modulate sickness symptoms and the efficacy of medication in patients with inflammation?
Inflammation plays a role in many diseases, such as infections, neuropsychiatric disorders and chronic pain. However, the messengers released by inflammation not only activate the immune system but also have an effect on the brain. This can cause immune-mediated symptoms, such as depressive mood, increased sensation of pain, fatigue or non-specific physical symptoms. How can positive expectations counteract these symptoms and influence the efficacy of anti-inflammatory medication?
Effects of positive treatment expectations on immune-mediated sickness symptoms in a human model of acute systemic inflammation
This project investigates how treatment expectations modulate the efficacy of an active anti-inflammatory medication on immune-mediated sickness symptoms. The experimental model of inflammation used will enable us to characterise expectation effects on immune-mediated sickness symptoms, inflammatory parameters and the efficacy of anti-inflammatory treatment. Resting-state fMRI (functional magnetic resonance imaging) and DTI (diffusion tensor imaging) data will provide a first insight into the importance of the prefrontal cortex and insula for these effects.
