Adolescence and disease

: The difficulties of the combined analysis of two factors, as illness behaviour and adolescence are studying in our work. Most authors support the subjectivity and impression of this field of investigation. We consider some relevant aspects in adolescence and the effects of the illness situation on it. We concluded it's necessary to realize particular and individual analysis of this problem, because it's not possible to report a general conclusion. However, it's possible to realize some predictions about some conflict global areas of behaviour and personality. We analyze the trends of behaviour, adaptative or not, and the differential effects of the illness (chronic and acute). We review the effects of the life-events and the social support on the behaviour, and the relevancy of some particular and transitory aspects of the people on his behaviour.
