Question Answer
aphasiaThe inability to understand or produce speech.
arterial ruptureRupture of a cerebral artery that may contribute to interruption of cerebral blood flow.
atherosclerosisA disorder in which cholesterol and calcium build up inside the walls of blood vessels, forming plaque, which eventually leads to partial or complete blockage of blood flow and the formation of clots that can break off and embolize.
auraA sensation experienced prior to a seizure; serves as a warning sign that a seizure is about to occur.
cerebral embolismObstruction of a cerebral artery caused by a clot that was formed elsewhere in the body and traveled to the brain
cerebrovascular accident (CVA)An interruption of blood flow to the brain that results in the loss of brain function.
comaA state of profound unconsciousness from which one cannot be roused.
coup-contrecoup brain injuryA brain injury that occurs when force is applied to the head and energy transmission through brain tissue causes injury on the opposite side of original impact.
dysarthriaThe inability to pronounce speech clearly, often due to loss of the nerves or brain cells that control the small muscles in the larynx.
expressive aphasiaA speech disorder in which a person can understand what is being said but cannot produce the right sounds in order to speak properly.
febrile seizuresConvulsions that result from sudden high fevers, particularly in children.
generalized seizureSeizure characterized by severe twitching of all the body's muscles that may last several minutes or more; also known as a grand mal seizure.
hemiparesisWeakness on one side of the body.
hemorrhagic strokeOne of the two main types of stroke; occurs as a result of bleeding inside the brain.
hypoglycemiaAn abnormally low blood glucose level.
incontinenceLoss of bowel and bladder control due to a generalized seizure.
infarcted cellsCells in the brain that die as a result of loss of blood flow to the brain.
ischemiaA lack of oxygen that deprives tissues of necessary nutrients.
ischemic strokeOne of the two main types of stroke; occurs when blood flow to a particular part of the brain is cut off by a blockage (eg, a clot) inside a blood vessel.
postictal statePeriod following a seizure that lasts between 5 and 30 minutes, characterized by labored respirations and some degree of altered mental status.
receptive aphasiaA speech disorder in which a person has trouble understanding speech but is able to speak clearly.
seizureGeneralized, uncoordinated muscular activity associated with loss of consciousness; a convulsion.
status epilepticusA condition in which seizures recur every few minutes, or last more than 30 minutes.
strokeA loss of brain function in certain brain cells that do not get enough oxygen during a CVA. Usually caused by obstruction of the blood vessels in the brain that feed oxygen to those brain cells.
thrombosisClotting of the cerebral arteries that may result in the interruption of cerebral blood flow and subsequent stroke.
tonic-clonicA type of seizure that features rhythmic back-and-forth motion of an extremity and body stiffness.
transient ischemic attack (TIA)A disorder of the brain in which brain cells temporarily stop working because of insufficient oxygen, causing stroke-like symptoms that resolve completely within 24 hours of onset.

Question Answer
acidosisA pathologic condition resulting from the accumulation of acids in the body.
diabetes mellitusA metabolic disorder in which the ability to metabolize carbohydrates (sugars) is impaired, usually because of a lack of insulin.
diabetic comaUnconsciousness caused by dehydration, very high blood glucose levels, and acidosis in diabetes.
diabetic ketoacidosis (DKA)A form of acidosis in uncontrolled diabetes in which certain acids accumulate when insulin is not available.
glucoseOne of the basic sugars; it is the primary fuel, along with oxygen, for cellular metabolism.
hormoneA chemical substance that regulates the activity of body organs and tissues; produced by a gland.
hyperglycemiaAbnormally high glucose level in the blood.
hypoglycemiaAn abnormally low blood glucose level.
insulinA hormone produced by the Islets of Langerhans (an exocrine gland on the pancreas) that enables glucose in the blood to enter the cells of the body; used in synthetic form to treat and control diabetes mellitus.
insulin shockUnconsciousness or altered mental status in a patient with diabetes, caused by significant hypoglycemia; usually the result of excessive exercise and activity or failure to eat after a routine dose of insulin.
Kussmaul respirationsDeep, rapid breathing; usually the result of an accumulation of certain acids when insulin is not available in the body.
polydipsiaExcessive thirst persisting for long periods of time despite reasonable fluid intake; often the result of excessive urination.
polyphagiaExcessive eating; in diabetes, the inability to use glucose properly can cause a sense of hunger.
polyuriaThe passage of an unusually large volume of urine in a given period; in diabetes, this can result from wasting of glucose in the urine.
type I diabetesThe type of diabetic disease that usually starts in childhood and requires insulin for proper treatment and control.
type II diabetesThe type of diabetic disease that usually starts in later life and often can be controlled through diet and oral medications.

anaphylaxisAn extreme, possibly life-threatening systemic allergic reaction that may include shock and respiratory failure.
envenomationThe act of injecting venom.
epinephrineA substance produced by the body (commonly called adrenaline), and a drug produced by pharmaceutical companies that increases pulse rate and blood pressure; the drug of choice for an anaphylactic reaction.
histaminesSubstance released by the immune system in allergic reactions that are responsible for many of the symptoms of anaphylaxis.
leukotrienesChemical substances that contribute to anaphylaxis; released by the immune system in allergic reactions.
stridorA harsh, high-pitched, crowing inspiratory sound, such as the sound often heard in acute laryngeal (upper airway) obstruction.
toxinA poison or harmful substance.
urticariaSmall spots of generalized itching and/or burning that appear as multiple raised areas on the skin; hives.
