Over the past few years, a great number of research projects have focused on the study of the mechanisms involved in integrated treatments and their effectiveness similarly, chronic diseases, stress-related conditions and the major psychiatric disorders have been increasingly framed within multifactorial gene-environment interactions.
It has been widely documented that genesinteract with the environment in order to modulate behavior and cognition in sickness and health (Hsieh, J., & Eisch, A.J. , 2010) by way of complex mechanisms which regulate their activity. These interactions have been proven to involve a particular class of genes, frequently referred to as activity or experience-dependent genes, which can be activated by signals from the physical and psychosocial environment to modulate the complex functions of physiology and psychology (Rossi, 2002, 2004, 2007; Lloyd & Rossi, 1992, 2008).
