Summary
This document provides a list of steps involved in various neurological conditions, such as hyponatremia, hypocalcemia, concussion, and SAH. It details the order of events in each condition, which can be helpful for understanding these medical processes. The steps are presented sequentially, focusing on the causal factors and their effects.

Arrange the steps in order: hyponatremia to seizure activity. _8_ Seizures _1_ Water intoxication _2_ Hyponatremia _7_ Cerebral Ischemia _5_ Brain cells swell _3_ Osmolarity of the blood drops _6_ Blood vessels are compressed _4_ Fluid is pulled from blood vessels into the brain Arrange the steps in order: hypocalcemia to seizure activity. _4_ seizures _2_ sodium channels open _1_ hypocalcemia _3_ lower threshold stimuli Cortisol-like drugs, Mannitol ® and draining off CSF: Arrange the steps in order: decreasing intracranial volume 🡪 reversing ischemia. _1_ decrease intracranial volume _4_ re-oxygenate the brain _2_ decrease pressure _3_ decompress cerebral arteries _5_ reverse cerebral ischemia _6_ save the tissues Arrange the steps in order: Concussion. _4_ axons stretched or twisted _1_ something “crashes” into the skull _2_ brain moves within the skull _3_ brain elongates Arrange the steps in order: SAH. (Subarachnoid hemorrhage) _4_ IICP and ischemia _5_ changes in LOC _1_ rupture of middle cerebral artery aneurysm _2_ bleeding into the subarachnoid space _3_ headache, stiff neck, photophobia Arrange the steps in order: meningitis to hydrocephalus _1_ exposure to Haemophilus influenzae _2_ meninges are inflamed [meningitis] _3_ meninges become swollen _6_ hydrocephalus on x-ray _4_ less CSF enters the subarachnoid space _5_ CSF backs up into the lateral ventricles
