Delirium is a disturbance of the content of thought, product of a deviant and tendentious, trial which elaborates a plot more or less complex, more or less plausible or absurd, but always pathologically flawed, and whose reality the patient has a full certainty and remains irreducible in their convictions. Respect of judgment can point out that it accomplishes its function through two stages. The first stage of development is through relationship and identification and the second critical stage is fulfilled through the comparison and assessment. With respect to the pathological error what can be said is that it is different from the normal error that is irreducible, is not achieved by experience, by demonstration, or by persuasion. This pathological error arises from the failure of the judicativa function that is evident in the delusional subject by diverted a comparison and assessment.

From here will depart work to relate the delirious with the history issue and get to know something about the way in which certain events and relations led to the current disease and, perhaps, to find in any case an explanation that trespass the border of diagnosis and bring us closer to a why..
