Normal intracranial regulation - ANS this relies on the interaction between the cerebrum,
cerebellum, diencephalon, and brain stem and transmission of nerve impulses across neuronal
synapses by neurotransmitters
cerebrum - ANS higher order thought processes come from
cerebellum - ANS regulates gait and balance
diencephalon - ANS neuro/endocrine function
brain stem - ANS breathing and vasomotor control
oxygen and nutrients for normal intracranial regulation - ANS sufficient blood volume,
cardiac output, oxygenation, perfusion, gas exchange, and glucose supply
frontal lobe - ANS personality and behavior with impulse control, manage anger, and make
right words
temporal lobe - ANS memory comes from and ability to interpret language
, ©EVERLY 2025 ALL RIGHTS RESERVED
dysarthria - ANS difficulty forming words
parietal lobe - ANS where your are in comparison to environment and most at risk for falls
occipital lobe - ANS vision; hard time naming objects
cerebellum - ANS coordination and gate and Romberg's test to assess function
causes of impaired intracranial regulation - ANS trauma, tumors, infections, hemorrhage,
toxicity, seizures, epilepsy, alzheimer's, lead, and impaired perfusion ischemic stroke, decreased
cardiac output, and hypoglycemia
hypoglycemia - ANS slurred speech, disorientation, and sweating
consequences of impaired intracranial regulation - ANS cerebral edema and increased
intracranial pressure/hypertension
cerebral edema vasogenic - ANS breakdown of blood-brain barrier and failure of
autoregulation
cerebral edema cytotoxic - ANS cellular energy failure resulting in anaerobic metabolism
from hypoxia or poor perfusion and production of lactic acid and tissues will swell until it bursts
cerebral edema interstitial - ANS increased intraventricular pressure from hydrocephalus
that cause the migration of CSF into the extacellular space
cerebral edema osmotic - ANS imbalance of osmolality between serum plasma and brain
tissue from hyponatremia
, ©EVERLY 2025 ALL RIGHTS RESERVED
hyponatremia - ANS this leads to seizures because blood becomes hypoosmolar and lead to
swelling of brain from fluid collecting
intracranial hypertension - ANS pressure inside of brain is high enough to where blood will
not flow there
causes of increase brain tissue - ANS tumors, traumatic or surgical injury, hematoma,
hemorrhage, and swelling
cause of increase CSF - ANS hydrocephalus and will cause decreased room for brain tissue
and blood
cause of increase blood in brain - ANS vasodilation, cervical collar or ET because blood will
have hard time flowing back down to body
abnormal intracranial regulation symptoms - ANS altered LOC, headache, vomiting,
abnormal speech, and cognition
glasgow coma scale - ANS eyes, verbal, motor
Max- 15 pts, below 8= coma
papilledema - ANS cranial nerve 2 compression from tumor and optic disc will be less clear
and without borders
PERRLA - ANS this can not be assessed with unresponsive patient because they cant follow
commands for accommodation
