Convulsive disorders are characterized by 4 things what are they?
|
Alteration of consciousness
Convulsive movements loss of muscle tone disturbance in feeling/behavior |
|
Tonic-clonic, absence, and minor motor seizures are all?
|
Generalized seizures
|
|
Status epilepticus is what?
|
Continuation of seizures that is very life threatening
|
|
These seizures have a bird like cry, generalized motor seizures, tonic then clonic, loss ov consciousness, possible bowel anb bladder control loss. HIGH AMPLITUDE
|
Tonic -clonic seizures
|
|
Alterered state of conciousness lasting only a few seconds. Have blank stare for a few seconds then come back. Have EEG spike and dome 3/sec
|
absence seizures
|
|
This is a minor motor seizure with loss of back muscle tone so patient falls?
|
Akinetic (atonic)
|
|
Jackkniffing movements in the seizures?
|
Myoclonic spasms
|
|
Partial seizures cause what?
|
Alterations in behavior or perception
|
|
What is a Jacksonian March? what is it associated with?
|
Watch as seizure spreads from the focus of the seizure outward, starts at one part of motor cortex and goes out. Partial seizures
|
|
Seizures have a synchronous ??? similar to a symphany all playing same note
|
Neural discharge that lowers the firing threshold
|
|
3 actions of antiseizure meds?
|
Depress epileptic focus by increasing refactory period and decreasing repetitive firing. Inhibition of discharge away from the focus by altering synaptic transmission. REDUCE excitatory NT
|
|
For excitatory synapses you have drugs act on what?
|
Na channels, Ca channels for depolarization and K for hyperpolar.
|
|
This the first seizure medication, the problem was that the patients were always sleepy?
|
Pheonobarbital
|
|
Valproic acid is what?
|
A solvent for other drugs
|
|
Useful drug for the treatment of absence seizures?
|
Ethosuximide
|
|
Used for generalized tonic/clonic seizures and for stabalization of status epilepticus. It depresses the membrane exitability by reducing Na conductance, more often used in children than adults. What am I
|
Phenytoin
|
|
This drug causes an increase in plasma levels?
|
Phenytoin
|
|
Can cause cleft palate in children and cause gingival hyperplasia and hirsutism, also blood dyscrasias?
|
Phenytoin
|
|
If you need to increase the dose of this drug it should be done in small increment?
|
Phenytoin
|
|
Why is phenytoin a good drug?
|
Can be used with other anticonvulsants
|
|
Blocks Na channel activity and is an anticonvulsant as well as a treatment for cardiac dysrhythmias?
|
Phenytoin
|
|
This drug is given for iv loading in status epilepticus and is the secondary drug given after lorazepam or diazapa?
|
Fosphenytoin
|
|
This drug is related to tricyclic antidepressions. Used for treatment of neuropathic pain and generalized tonic/clonic seizures. Inhibbits na conductance and presynaptic txmission?
|
Carbamazepine
|
|
Causes an aplastic anemia and has an erratic absorption rate?
|
Carbamazepine
|
|
Cannot use this drug with MAO inhibitors?
|
Carbamazepine
|
|
This drug causes a decrease of other anticonvulsants by enzyme induction?
|
Carbamazepine
|
|
This drug is similar to carbamazapine but less toxic and longer acting?
|
Oxcarbazepine
|
|
Phenobarbital has traditionally been given for what?
|
Febrile seizures in kids
|
|
Phenobarbitals mechanism is?
|
potentiates GABA (increase Cl and decrease Na conductance=hyperpolarization. Antagonizes glutamate excitatory pathways
|
|
what inhibits phenobarbital metabolism?
|
Valproic acid
|
|
What is structurally similar to phenobarbital with action is similar to phenytoin?
|
Primidone
|
|
The drug is converted to phenobarbital and another active metabolite
|
primidone
|
|
Give this for uncomplicated absence seizures?
|
Ethosuximide
|
|
The mechanism for ethosuximide is what?
|
affect Ca channel activity and NT release
|
|
This decrease ethosuximide metabolism?
|
Valproic acid
|
|
The drug is given for myoclonic seizures?
|
Valproic acid
|
|
The mechanism for valproic acid is?
|
Inhibits catabolic enzymes to GABA so Increase GABA, voltage sensitive Na channels, may block the NMDA receptor
