This can appear as consequncia of trivial traumas and present sintomatologia weeks or months after the trauma. The subdurais hematomas cause diffuse upheavals in general, confusional syndrome. Dficits neuropsicolgicos is reversible in the majority of the cases as soon as ceases compression (JUNQU; BRUNA; MATAR, 2001). The subaracnidea hemorrhage is a bleed that extravasa for the space subaracnide, that he is situated enters the two meninges the arachnoid one to piamter. In many cases it is detected by lumbar puno, this hemorrhage it can cause hidrocefalia and it can produce ischemic injuries for vasoespasmo (ROWLAND, 2002). The hemorrhages intraventriculares can cause the death for compression, as well as confusionais states, changes of character and amnesia, for the compression of the lmbico system, that ace times is irreversible. In more serious cases they can cause dementias of frontolmbicas characteristics (JUNQU; BRUNA; MATAR, 2001). The intracerebrais hematomas costumam to develop in the lobes secular and frontal, after a trauma.
They are the responsible ones for sequelas neuropsicolgicas focal, reversible depending on its size, localization and relative implication of the cinereous substance. Sequelas enters more frequent they are to the nominal aphasia or difficulty in evoking the name of objects (JUNQU; BRUNA; MATAR, 2001). CEREBRAL 2.5CONTUSES AND LACERAES the cerebral bruises are focal hemorrhages in parnquima, that they elapse of esfoladuras of the brain to if moving through the internal surface of the skull, can occur in the place of the breaking. Normally multiple the small bruises are e, frequent increase of size in 12 the 24 hours being able to prove one day the injury after. Already the lacerao is the rupture of meninges or the fabric cerebral, generally consequncia of cuts caused for acute edges of depressed cranianos fragmentos (ROWLAND, 2002). 2.6EDEMA CEREBRAL edema cerebral has as characteristic basic the increase of the volume of extra water and intracellular, they can be focal or diffuse and sufficients will be had intensities, can create a mass effect that can lead the death for compression.
