An absence seizure (petit mal) is an example of a generalized seizure
True
False
A partial (focal) seizure, such as "simple partial" is associated with preservation of consciousness.
True
Paul's
Status epilepticus has been defined as a seizure lasting continuously for 5-30 min.
True
False
Since control of a given seizure type in a patient is predictable based on attainment of a specific serum drug level defined by the seizure type, appropriate treatment is assured with the attainment of this drug level.
True
False
An advantage of treating absence seizures is that the seizure is notable in that it responds to most drugs used for both generalized tonic-clonic and complex partial seizures.
True
False
Most seizures are controllable with monotherapy-i.e. therapy using only one drug.
True
False
Actions of most anticonvulsive agents:
Mediating inhibitory (GABA-related) synaptic transmission in the brain
Inhibiting excitatory synaptic neurotransmission in the brain, mediated by the neurotransmitter glutamate.
Both
Neither
This drugs is indicated only for management of partial seizures.
