Lecture Luana Colloca: ‘The nocebo effect: How expectations can make you sick’

Luana Colloca (bio) from the University of Maryland School of Nursing will visit Leiden University on 15 September (2017) to give a lecture about the nocebo effect. From 15:00 till 16:00 at the Faculty of Social Sciences (Wassenaarseweg 52, 2333 AK Leiden) in room SA-41.

 



Abstract

Recently, there has been a host of research over the past several decades that expanded our knowledge of the mysterious phenomenon we know as ‘the nocebo effect’. Understanding its mechanisms from a psychoneurobiological viewpoint has permitted a better understanding of how nocebo effects can be minimized. The anticipation of side effects engages a complex set of neural circuits along with biochemical changes both in the peripheral tissues and in the central nervous system resulting in the occurrence and/or worsening of clinical outcomes.

Nocebo effects are formed through anticipation of adverse events, prior therapeutic unsuccessful experiences and observation of adverse events in others.  Susceptibility to the nocebo effect depends upon conscious and nonconscious processes, personality traits, psychological factors and genetic variants.

Moreover, providers’ behaviors, environmental cues and the appearance of medical devices can induce nocebo effects that dramatically influence clinical outcomes in patients. Knowledge on the mechanisms of nocebo effects can definitely be valuable to daily clinical practice and psychological counselling.

This lecture is available for everyone!
