Ch 18 - Neuro Emergencies - Vocab Flashcards
altered mental status
Any deviation from alert and oriented to person, place, time, and event, or any deviation from a patient’s normal baseline mental status.
aneurysm
A swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall.
aphasia
The inability to understand and/or produce speech.
atherosclerosis
A disorder in which cholesterol and calcium build up inside the walls of blood vessels, eventually leading to partial or complete blockage of blood flow.
aura
A sensation experienced before a seizure; serves as a warning sign that a seizure is about to occur.
cerebrovascular accident (CVA)
An interruption of blood flow to the brain that results in the loss of brain function; also called a stroke.
coma
A state of profound unconsciousness from which the patient cannot be roused.
delirium
A temporary change in mental status characterized by disorganized thoughts, inattention, memory loss, disorientation, striking changes in personality and affect, hallucinations, delusions, or a decreased level of consciousness.
dysarthria
Slurred speech.
embolus
A blood clot or other substance in the circulatory system that travels to a blood vessel where it causes a blockage of blood flow.
epilepsy
A disorder in which abnormal electrical discharges occur in the brain, causing seizures and possible loss of consciousness.
febrile seizures
Seizures that result from sudden high fevers; most often seen in children.
focal seizure
A seizure affecting a limited portion of the brain.
generalized seizure
A seizure characterized by severe twitching of all of the body’s muscles that may last several minutes or more; formerly known as a grand mal seizure
hemiparesis
Weakness on one side of the body.
hemorrhagic stroke
A type of stroke that occurs as a result of bleeding inside the brain.
hyperglycemia
An abnormally high blood glucose level.
hypoglycemia
An abnormally low blood glucose level.
incontinence
Loss of bowel and/or bladder control; may be the result of a generalized seizure.
ischemia
A 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
A type of stroke that occurs when blood flow to a particular part of the brain is cut off by a blockage (eg, a blood clot) inside a blood vessel.
postictal state
The period following a seizure that lasts 5 to 30 minutes; characterized by labored respirations and some degree of altered mental status.
seizure
A neurologic episode caused by a 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
A condition in which seizures recur every few minutes or last longer than 30 minutes.
