Adriana Arza Valdés Junio 2017, Barcelona A BSTRACT The incidents of anxiety, depression, epilepsy, multiple sclerosis, pathological stress, as well as other different stress related diseases have significantly increased in recent years and it is most probably due to dramatic changes in the daily lifestyle of citizens. The social and medical problems associated to stress are clearly on the rise and seriously affecting mental health and wellbeing not only in adults but also in young adults and children, according to the WHO (World Health Organization). There is currently an increased awareness of stress, specifically with regards to its medical, social and economic importance; and also, because there are several stress- related comorbidities that remain largely understudied. Therefore, stress has become one of the significant focal points of research interest. Despite the efforts made, a scientifically supported, repeatable and usable in daily life measurement method of stress is still not available. An objective and reliable measurement of stress level could be used to compare the level of stress’ severity in different individuals or between different sets of professionals. It would also be a crucial tool for the prevention, diagnosis and treatment of several diseases. Stress can be defined as the disturbance of the homeostatic balance when facing a specific threat to the body (a stressor) that provokes a stress response. The stress response is the body’s attempt to deal with the stressor triggering the different reactions that can be broadly summarised as changes in the autonomous nervous system, a hormonal response (adrenal pituitary adrenal axis) and a behavioural change and/or a decrease in cognitive skills. The methods that have been proposed until now for measuring the different aspects of stress considering its multidimensional quality, can be gathered in three groups: psychometric tests, biochemical markers, and physiological markers. Although biochemical samples and psychometric questionnaires are commonly used stress markers, they do not allow continuous or even regular stress assessment. i
