Seizures Flashcards
What percentage of the population will have a seizures during their lifetime?
10%
What is the definition of a simple partial seizure?
a seizure that begins in a focal area of the brain and does not impair awareness.
What is the definition of a complex partial seizure/
a seizure with a focal onset that causes an impairment in awareness
Where is the most common location of onset for a complex partial seizure?
temporal lobe
What are some typical signs of a complex partial seizure?
lip smacking, chewing movements, picking at clothes, etc.
How do generalized tonic-clonic seizures typically start?
with a tonic phase that lasts several seconds in which the entire body becomes stiff, followed by a clonic phase
True or false: the rhythmic jerking of the clonic phase tends to occur asymmetrically in the body.
false - symmetric
What is the classic EEG finding in absence seizures?
three-per-second generalized spike-and-wave pattern
Is an absence seizure focal or generalized?
generalized
What is the most common cause of seizures in children?
febrile
What is the most common cause of seizures in the elderly?
stroke
What genetic cause of seizures will present in childhood with essentially any seizure type, intellectual disability and an EEG with slow (1 to 2/second) spike and wave discharges?
Lennox-Gastaut syndrome
What genetic epilepsy syndrome will present in childhood with simple partial seizures that have a nocturnal preponderance with centrotemporal spikes on an EEG?
benign rolandic epilepsy
What genetic epilepsy syndrome will present in adolescence or young adulthood with myoclonic, absence, or generalized tonic-clonic seizures occurring mainly in the early morning with a 4 to 6/per second polyspike and wave pattern on EEG?
Juvenile myoclonic epilepsy
Todd’s paralysis will typically be seen after what type of seizure?
after a secondarily generalized seizure
