[The features of insight in schizophrenia, a bibliographic review]

Treatment of schizophrenia remains a huge challenge. Despite advances in recent decades in pathophysiology, genetics, and therapeutics, overall outcomes in the evolution of patients do not appear to have undergone such significant changes. Cognition is particularly important, bearing in mind that it is a determining factor in functionality, and this, in turn, in social, family, academic and work performance. Cognitive variables may include the ability to Insight as a form of self-recognition that goes beyond disease awareness. Like all cognitive functions, it is also impaired in patients and hinders, perhaps like no other, adherence to treatment, with the possibility of poor evolution, relapses and worse prognosis. The objective of this paper is to investigate, through a literature review, the characteristics of Insight and what is its importance in the clinical and prognostic of schizophrenia.
