R.EEG. T Part 5
Temporal intermittent rhythmic delta activity is associated with clinical finding? - answer
Temporal lobe epilepsy
Which EEG finding is most often associated with juvenile myoclonic epilepsy - answer4-
5hz generalized spike-wave discharges and high voltage polyspikes in sleep
List the Lennox-Gas taut triad - answer1-Mixed seizures including atypical absence,
atonic, tonic and myoclonic
2. Cognitive dysfunction
3. Slow spike and wave pattern at 2-2.5hz
What EEG finding is most often associated with locked-in syndrome - answer Normal
wake and sleep patterns
What EEG pattern is most often seen following an acute cerebrovascular accident
(CVA) – answer PLEDS
What EEG finding is most often associated with infarction within the territory of the
posterior cerebral artery - answer Loss or decrease of alpha rhythm on the side of the
stroke along with focal slowing in the posterior temp, parietal and occipital regions
What EEG finding is most often associated with metabolic, especially hepatic,
encephalopathy - answerTriphasic waves
What EEG finding is most often associated with subacute sclerosing panencephalitis
(SSPE) - answerBilaterally symmetric and synchronous, high amp, periodic bursts every
4 to 10 seconds
What EEG finding is most often associated with herpes simplex virus (HSE) -
answerFocal temporal or frontotemporal spikes or sharp waves that can be unilateral or
bilateral usually occurring periodically at a rate of 1 every 1 to 5 seconds
What EEG finding is most often associated with severe anoxic encephalopathy -
answerBurst suppression that may or not be associated with clinical myoclonic jerks
What EEG finding is most often associated with Creutz-Jakob disease - answerInitially
the EEG shows slower than normal activity with loss of normal background. With
disease progression bursts of moderate voltage biphasic and triphasic sharp waves
intervals 2 to1 or less than 1 sec
