ICP Presentation of s/sx usually depends on compression/infiltration of specific tissue, cerebral edema and increased ____ deficit of cerebral function, HA, and seizures; s/sx of increased ICP; s/sx related specific cerebral functions what are the three categories of resulting s/sx? headaches s/sx: early sign, seen in approx 1/3 of patients, usu worse in AM, intermittent, not severe seizures s/sx: 20-50% of adults will experience, may be first sign, seen mainly in supratentorial tumors vomiting s/sx: seen most often with posterior fossa tumors, may accompany headaches, can be projectile and unrelated to food, common in morning, direct stimulation of vomiting center in medulla increased ICP change in LOC, pupillary changes, motor weakness, sensory deficits, cranial nerve palsy, possible HA, possible seizures are all s/sx of what early finding? continued deterioration in LOC, vomiting, HA, hemiplegia, posturing, vital sign changes, irregular respirations, brain stem reflex impairment what are some of the later findings of increased ICP? frontal lobe which lobe are these s/sx related to? innappropriate behavior, inability to concentrate, lack of restraint parietal lobe which lobe are these s/sx related to? hyperesthesia (excessive physicial sensitivity), paresthesia (burning or prickling sensation), autopagnosia (inability to localize different parts of body), agraphia (loss of ability to write) temporal lobe which lobes are these s/sx related to? psychomotor seizures (visual, auditory or olfactory hallucinations). if dominant lobe involved, receptive aphasia may occur with encroachment on wernickes area occipital lobe which lobe are these s/sx related to? assocaited with vision (contralateral homonymous hemianopia) visual loss in half of each visual field on opposite side of lesion
