Module 2 AEDs Slide 19-30
Question | Answer |
---|---|
An alteration in behavior, function, and/or consciousness that results from an abnormal electrical discharge of neurons in the brain. | Seizure pg 490 (M2/16) |
Used to describe chronic unprovided recurrent seizures. | Epilepsy pg 490 (M2/16) |
Treatment chosen for seizure disorder depends on type of seizure; thus, the correct diagnosis of seizure disorder is imperative. True or False? | True, pg 490 (M2/16) |
Type of seizure with no immediate cause. | Unprovoked seizure 490 (M2/16) |
This type of seizure occurs due to trauma, metabolic abnormalities, high fever, drug abuse or alcohol intoxication, etc. | Provoked seizure 490 (M2/16) |
Psychological in origin and occurs due to severe stress or emotional trauma. | Non-epileptic (pseudoseizures) 490 (M2/16) |
Most common in children and etiology is unknown in most cases. | Seizures (M2/17) 490 |
Seizures are classified according to which part of the ________ is affected. | brain 490 (M2/17) |
What are the 8 mechanisms of action for AED Classes? hydantoins, GABA analogs, carbamazepine, _____ _______ ______ Pregabalin topiramate | 1)Hydantoins 2)GABA Analogs 3)Carbamazepine 4)Barbiturates 5)Benzodiazepines 6)Carbamazepine 7)Barbiturates 8)Benzodiazepines 9)Gabapentin 10)Pregabalin 11)Topiramate 490-491 (M2/18) |
Works at the primary motor cortex to block sodium channels in the neurons which decreases hyperexcitability. | HYDANTOINS 490 (M2/18) |
Believed to increase the actions GABA (an inhibitory neurotransmitter) and inhibit sodium channels which stablize the membranes of the neuron. | GABA Analogs 490 (M2/18) |
Inhibits depolarization of neurons by binding to GABA receptors, which enhances transmission of chloride ions. They also increase the seizure threshold of the motor cortex of the brain. | Barbiturates 491 (M2/18) |
Increase Chloride channels, which diminished seizure activity. | Benzodiazepines 491 (M2/18) |
Majority can be prescribed together if multiple AEDs are needed to control seizures. | AEDs (M2/18) |
Focal motor or sensory symptoms; reflects area of brain affected; no change in consciousness. | Simple partial seizure 490 (M2/19) |
characterized by an aura, followed by impaired consciousness with automatisms, usually originating from temporaral lobe | Complex partial seizure 490 (M2/19) |
Simple or complex partial seizures that progress to generalized tonic-clinic seizures | Secondarily generalized 490 (M2/19) |
Formerly grand mal; sudden LOC w tonic-clonic motor activity; postictal state of confusion, drowsiness and headache | Generalized tonic-clonic 490 (M2/19) |
Formerly petit mal; brief (<30 seconds) episodes of unresponsiveness characterized by staring, blinking, or facial twitching. | Absence 490 (M2/19) |
series of brief jerky contractions of specific muscle groups | Myoclonic 490 (M2/19) |
Unable to control with other medications | Refractory 490 (M2/19) |
What are the DOC of partial (focal, local),partial simple,partial complex,partial seizures w secondary generalization and partial seizures? | Carbamazepine (Tegretol) lamotigine oxcarbazepine levitiracetam CLOL 490 (M2/19) |
Valproate (Depakene lamotigine levetiracetam What type of seizure are these the DOC for? | Generalized convulsive (M2/19)490 |
What are the DOC for generalized nonconvulsive, absence, petit mal seizures? | Ethosuximide (Zarontin) Valproate 490 (M2/19) |
Patients with status epilepticus who are given midazolam through an autoinjector rather than IV lorazepam are more likely to be seizure free by the time they arrive at the hospital and are also less likely to require hospitalizeion. True or False? | True 492 |
What are the 3 classes of AEDs (Anti-epileptic Drugs) with key drugs? 1)Phenytoin (Dilantin 2)Ethosuximide (Zarontin) 3)Valproic acid (Depakene), Divalproex sodium (Depakote), Gabapentin (Neurontin), Lamotigine (Lamictal), Pregabalin (Lyrica) | 1)Hydantoin 2)Succinimide 3)GABA analogs Note:GABA also includes Topiramate (Topamax) (M2/20) 488 |
What are the 3 classes of AEDs (Anti-epileptic Drugs) with key drugs? 1)Phenobarbital (Luminal) & Topiramate (Topamax) 2)Diazepam (Valium)&Primidone (Mysoline) 3)Carbamazepine (Tegretol, Epitol), oxcarbazepine (Trileptal), &levetiracetam (Keppra) | 1)Barbiturates 2)Benzodiazepines 3)Miscellaneous (M2/20) 488 |
