Two forms of seizures in idiopathic epilepsy
Generalized tonic clinic and absence seizures
4 things the EEG is used for in the diagnosis of epilepsy
1) Assisting in determining the correct diagnosis
2) locating the epileptogenic area
3) determining the presence or absence of brain damage
4) effectiveness of anticonvulsant therapy
If a patient has a focal seizure in which he has twitching of just his legs, what would the EEG look like and what electrode would be primarily involved?
Focal theta or delta, sharp focal waves around CZ
Epilepsia partialis continua is focal muscle activity that persists longer than ____ minutes
30
Describe the EEG of epilepsia partialis continua
Continuous spikes, sharp waves, theta and slowing delta over corresponding cortex
Clinical picture of a patient during a Jacksonian March seizure
Twitching of mouth, toe and arm. May progress involving more and more muscles on the same side of the body as the discharges spread up and down the motor strip
Where does seizure activity originate in adversive seizures?
Mid portion of the frontal lobe
Describe the EEG with an adversive seizure
Rhythmical slowing, becoming very widespread/ variable with spike activity
F3 and F4
Define epilepsy
A paroxysmal disturbance of CNS function, which is recurrent, stereotyped in character and associated with excessive neuronal discharges
Automatism
More or less coordinated involuntary motor activity occurring during the state of clouding of consciousness
Partial seizure with auditory sensory symptoms is where?
Temporal
Partial seizure involving special visual sensory symptoms
Hallucinations, flashes of light occipital posterior temporal spikes
Another name for olfactory
Uncinate fits/ mid temporal
Postural seizure left arm forward
Variable with focal spike activity in corresponding motor cortex RIGHT c4
