These mental alterations involve the thought the perception and the representation, so that the distorted perceptions transform in the sustenance of irrational beliefs, which demonstrate in the dynamics of the delirium.The most interesting of all that, is that in the patient the delirium is configurated as explanation of his hallucination.

here are two links of websites related to the delirium and hallucination in diferents diseases:
