Chapter 18. Neurologic Emergencies Flashcards
Any deviation from alert and oriented to person, place, time, and event, or any deviation from a patient’s normal baseline mental status.
Altered Mental Status
A swelling or enlargement of the wall of a blood vessel that results from a weakening of the vessel wall.
Aneurysm
The inability to understand and/or produce speech.
Aphasia
A disorder in which 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.
Atherosclerosis
A sensation experienced before a seizure; serves as a warning sign that a seizure is about to occur.
Aura
An interruption of blood flow to the brain that results in the loss of brain function;
also called a stroke.
Cerebrovascular Accident (CVA)
A state of profound unconsciousness from which the patient cannot be roused.
Coma
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.
Delirium
Slurred speech.
Dysarthria
A blood clot or other substance in the circulatory system that travels to a blood vessel where it causes a blockage.
Embolus
Can result from atrial fibrillation or artherosclerosis.
A disorder in which abnormal electrical discharges occur in the brain, causing seizure and possible loss of consciousness.
Epilepsy
Seizures that result from sudden high fevers; most often seen in children.
Febrile Seizures
A seizure characterized by severe twitching of all of the body’s muscles that may last several minutes or more; known as grand mal seizure.
Generalized Seizures
Weakness on one side of the body.
Hemiparesis
A type of stroke that occurs as a result of bleeding inside the brain.
Hemorrhagic Stroke
Abnormally low blood glucose levels.
Hypoglycemia
Loss of bowel and/or bladder control; may be a result of generalized seizure.
Incontinence
A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial to complete blockage of blood flow; potentially reversible.
Ischemia
A type of stroke that occurs when blood flow to a particular part of the brain is cut off by blockage inside a blood vessel.
Ischemic Stroke
A seizure affecting a limited portion of the brain.
Focal Seizure
The period following a seizure that lasts 5 to 50 minutes; characterized by labored respirations and some degree of altered mental status.
Postictal State
