spina bifida occulta
incomplete closure of one or more vertebrae without protrusion of spinal cord or meninges
cerebrovascular accident (stroke) type 1
ischemic stroke - blood supply to brain is blocked or slowed
thrombotic ischemic stroke
occlusion builds up in artery
embolic ischemic stroke
blood clot that created somewhere in body and travels (embolism)
type 2 stroke
hemorrhagic stroke - rupture of cerebral blood vessel
intracerebral hemorrhage
rupture of vessel in brain
subarachnoid hemorrhage
release of blood into space surrounding brain, commonly caused by rupture aneurysm
TIA
transient ischemic attack - stroke like symptoms that resolve within 24 hours
alzheimers
neuritic plaques and neurofibrillary tangles
craniotomy
incision of skull to gain access to brain during neurological procedures
hydrocephalus
cranial enlargement caused by accumulation of fluid within ventricles of brain
neuritic plaques
sticky substance made of amyloid protein found in gray matter of brain
sciatica
severe pain in leg along course of sciatic nerve
poliomyelitis
inflammation og gray matter of spinal cord
trephination
excision of circular disk of bone using specialized saw called trephine - relieve ICP
