Question 16

focal seizure

Answer 16

begins in a focal cerebral cortical area

Question 17

simple focal seizure

Answer 17

begins in a focal cerebral cortical area; causes motor or seensory abnormalitis without altering awareness

Question 18

complex focal seizure

Answer 18

begins in a focal cerebral cortical area; causes abnormal awareness with or without motor or sensory abnormalities

Question 19

generalized seizure

Answer 19

involves majority of cerebral cortex at onset (primary) or eventually (secondary)
causes loss of consciousness, loss of ability to sit or stand without support

epilepsy with predominantly focal seizures

generalized tonic clonic seizures

Answer 25

diffuse tonic and clonic motor activity

Question 26

absence seizures

Answer 26

brief episodes of unawareness without tonic or clonic activity
generalized at onset
people retain ability to stand or sit
