seizure and epilepsy UPDATED ACTUAL Questions and
CORRECT Answers
seizure abnormal hypersynchronous electrical discharge involving neurons in the brain
epilepsy Condition where a person has recurrent, unprovoked seizures
- Having 2+ unprovoked seizures > 24h apart
- Patient has 1 unprovoked seizure and the risk of recurrence is >60% in the next
10 years
post-ictal occurring between the end of an epileptic seizure and return to baseline
condition
focal (partial) seizure arise from 1 part of the brain
- impairment of consciousness → complex
- NO impairment of consciousness → simple
can be focal to bilateral tonic-clonic
generalized seizures immediately and rapidly engage both cerebral hemispheres
- awareness lost
- motor vs nonmotor
cerebral cortex - covers lobes of cerebral hemispheres, connected by corp callosum.
- Made up of grey matter - neurons & glia
neurons analyze & process info, send signals thru axons that comprise white matter
- initiate and conduct impulses via neurotransmitters
, corpus callosum bundle of white fibers connects L & R hemispheres.
neurotransmitters chemical messengers that cross the synaptic gaps between neurons
can be overactive or underactive and lead to uncoordinated flow of electrical
activity
frontal lobe - Solve complex problems
- Express & control emotion
- Complex skilled movements
- Speech
parietal lobe - Sensation- touch, pressure
- Association areas
- Seldom source of seizures
occipital lobe - Vision, bright lights
- Uncommon source of sz.
temporal lobe - Left - enables us to understand language & speak in a way that makes sense
- Right - memory, emotions, smells
- Mesial part of temp lobe often source of sz
epidemiology of seizures - 5-10% have >1 seizure
- 0.3-0.5% with epilepsy
- early childhood and late adulthood more likely
