[Medical approach to "the Quixote"]

The study of the madness that turned the gentleman Alonso Quijano into the knight don Quixote, gives us no acceptable explanation about the reason of that mental disorder; this madness has already had a array of medical approaches. In order to understand it, there exist two possible factors: the repression of a sexual necessity which his nature imposed on himself, and the behaviour he was obliged to have because of his condition of gentleman; this study will try to explain and value these factors, taking also into account the information provided by the novel.
