Thus, it can be evidenced that it does not have consensus between the definition and the understanding of the found terms, although the subject very to be argued and to be studied enters the specialists of the area. As already observed, the cited terms above are many employed times inadequately. in the attempt of uniformizar them to allow one better communication between the professionals who act in the area of the learning and, thus, to minimize possible confusions, is necessary to establish what each one represents and also its especificidades. 3. WHAT IT IS LEARNING DIFFICULTY? OF?

However, both generate the failure pertaining to school. It fits to clarify, for one better understanding and reading of the article, the conflict in if using the terms ' ' transtornos' ' ' ' distrbios' '. The first one encloses the mental upheavals and the problems of behavior. According to CID-10 (1992), this term is used by all area of the mental health to prevent inherent problems to the use of other terms, such as illness or disease.
