Ch 17 Neurologic Emergencies Flashcards
Altered mental status
Any deviation from alert and oriented to person, place, time, event; deviation from a patient’s normal
Aneurysm
Swelling or enlargement of the wall of a blood vessel that results from weakening of the vessel wall
Aphasia
Inability to understand and/or produce speech
Atherosclerosis
Calcium and cholesterol build up inside the walls of the blood vessels, forming plaque, potentially leading to a partial or complete blockage of blood flow
Aura
Sensation experiences before a seizure, serves as a warning sign
CVA
Cerebrovascular accident/stroke; interruption of blood flow to the brain that results in the loss of brain function
Coma
State of profound unconsciousness from which the patient cannot be roused
Delerium
Temporary change in mental status characterized by disorganized thoughts, inattention, memory loss, disorientation, striking changes in personality and affect, hallucinations, delusions or a decreased LOC
Dysarthria
Slurred speech
Embolus
Blood blot or other substance in the circulatory system that travels to a blood vessel causing a blockage
Epilepsy
Disorder of abnormal electrical discharges in the brain, causing seizure and possible loss of consciousness
Febrile seizures
Seizures that result from sudden high fevers, most often seen in children
Generalized (tonic-clonic) seizures
Seizure characterized by severe twitching of all of the body’s muscles that may last several minutes or more; formally grand mal seizures
Hemiparesis
Weakness on one side of the body
Hemorrhagic stroke
Stroke that occurs as a result of bleeding inside the brain
Hypoglycemia
Abnormally low blood glucose level
Incontinence
Loss of bowel or bladder control; may be the result of generalized seizure
Ischemia
Lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow; potentially reversible because permanent injury has not yet occurred
Ischemic stroke
Stroke that occurs when blood flow to a particular part of the brain is cut off by a blockage (blood clot) inside a blood vessel
Partial (focal) seizure
Seizure affecting a limited portion of the brain
Postictal state
Period following a seizure that lasts 5 to 30 minutes; characterized by labored respirations and some degree of altered LOC
Seizure
Neuralgic episode episode caused by surge of electrical activity in the brain; can be a convulsion characterized by generalized; uncoordinated muscular activity and can be associated with loss of consciousness
Status epilepticus
Conditions where seizures recur every few minutes or lasts longer than 30 minutes
Syncope
Fainting spell or transient loss of consciousness
