Neurobiology of Placebo Effect
Plasebo Etkinin Nörobiyolojisi

Murat Erdem [1] , Süleyman Akarsu [2] , Murat Gülsün [3]


Placebo is defined as a substance or method that has no specific effect on the condition being treated. Placebo leads to the state of contentment and shows its effects just like a drug by the pathways in the body. Various changes formed by plasebo on the brain activation, neurotransmitters and hormones have been observed with the development of neuroimaging methods. The effects of dopamine, serotonin, and opioid systems in the formation of the placebo response; the relationship between placebo effect, reward cycle and expectation process and the role of the some specific regions in the brain where pharmacological agents acting on during the placebo response have been shown in several studies. There are similarities between hypnosis and the placebo effects and expectation of improvement is closely related to the suggesting phenomenon in the hypnosis as well as placebo responses. The formation of similar changes in the brain after administration of placebo and hypnosis associated with the expectation models and suggestions attracts attention. Neurochemical pathways in the brain constitute functional impact with many of the common mechanisms. Therefore, all of these mechanisms in the placebo response can take part in relation to each other. Although it is known that many factors may influence, understanding of the effects of placebo and viewing the changes in the brain formed by placebo have an important place for enlightening roles of psychological factors in the onset of diseases and treatment.
Plasebo, tedavi edilen duruma yönelik özgületkisi olmayan madde ya da yöntem olarak tanımlanmıştır. Plasebo, hoşnutluk durumuna yol açmakta, tıpkı bir ilacın etkisi gibi vücuttaki yolaklar aracılığıyla etkisini göstermektedir. Nörogörüntüleme yöntemlerinin gelişmesi ile plasebonun beyin aktivasyonu, nörotransmitterler ve hormonlar üzerinde çeşitli değişiklikler oluşturduğu gözlenmiştir. Plasebo cevabının oluşmasında dopamin, serotonin, opioid sistemlerinin etkisi, plasebo etkisinin beklenti süreci ve ödül döngüsü ile ilişkisi, farmakolojik ajanların etki ettiği beyindeki bazı özgül merkezlerin plasebo cevabı sırasındaki rolü çalışmalarda gösterilmiştir. Plasebo etkisi ile hipnozun etkisi arasında da benzerlikler vardır ve hem plasebo hem de hipnoz yanıtında iyileşme beklentisi telkin fenomeni ile yakından ilişkilidir. Telkin ve beklenti modelleri ile ilişkili olarak hem hipnoz hem de plasebo uygulanımı sonrası beyinde benzer değişiklikler oluşması ilgi çekmektedir. Beyindeki nörokimyasal yolaklar izole olarak değil birçok ortak mekanizmalarla fonksiyonel etki oluşturmaktadır. Bu nedenle plasebo yanıtında tüm bu mekanizmalar birbirleriyle ilişkili olarak görev alabilirler. Her ne kadar birçok faktörün etkisi olduğu göz önünde bulundurulsa da; plasebonun etkisini anlamanın ve beyinde yaptığı değişiklikleri görüntüleyebilmenin, psikolojik faktörlerin hastalıkların oluşumunda ve tedavisindeki rollerini aydınlatmada önemli yeri vardır.
