Abstract

Introduction: There is limited knowledge about the influence on cognitive functions of the treatments for brain tumors based on radiotherapy function after RT usually occur after a long period of time. (RT). Objective: To review the works conducted in recent years about the effects of RT on cognition in brain tumors. Method: Using EndNote software X5, articles containing �radiotherapy� and �cognition� in its title, keywords, abstracts or main text in the years 2009-2011 were extracted. Also, an extensive search through the references of articles taken was done. Those works that did not reflect the relationship between RT and the development of cognitive impairment or did not focus on brain tumors were disregarded. Results: 14 articles were selected: 7 originals, 6 reviews, and 1 opinion article. The findings focused on three aspects: a) cognitive impairment due to the RT, b) risk factors for cognitive impairment induced by RT c) time from the application of RT to the onset of cognitive impairment. Conclusions: The new studies confirm findings of recent decades, namely that the functions most commonly affected are attention, memory and learning, psychomotor and executive functions; that there are identifiable risk factors for cognitive impairment associated to RT; and that alterations in cognitive
