ABRET EEG QUESTIONS AND ANSWERS

Rolandic Spikes - what type of spikes are seen most often in children 5-6 Hz - by year one what should the dominant background rhythm be 5 Hz - what should the PDR of a awake 5 month old infant be ORIDA - what encephalopathic EEG pattern is most commonly associated with children Benign Rolandic Epilepsy - onset of between 3 and 13 years begins with sensorimotor manifestations on one side of the face and mouth Unilateral oral paresthesias as well as facial clonic and/or tonic activity are common Speech arrest hypersalivation most common focal epilepsy of childhood the most common focal epilepsy in adults is temporal lobe epilepsy. Posterior Slow Waves of Youth (PSWY) - High voltage theta or delta waves, commonly seen in children 8-14 years of age, accentuated by hyperventilation 3-6 months - a reactive PDR to eye closure first appears around how many months of age Electral decrementals - what is a sign of infantile spasms in a EEG delta brush - A pattern of 1-1.5 Hz activity with superimposed 8-12 hz activity that is seen in neonates is called whatTrace Alternant - Bursts of slow waves, at times intermixed with sharp waves and intervening periods of relative quiescence (quiet and inactive) with extreme low-amplitude activity central - where are delta brushes expected to be seen in a 27 week old neonate 32-34 weeks - delta brush patterns are commonly seen at what age Hypsarrhythmia - In the Periods between seizures, EEG shows Irregular and disorganized activity in the EEG. no distinguishable pattern, often seen in Infantile Spams posative - what type of polarity does lambda have Highest number 5 Hz - if you want to attenuate slow waves (ie. make slow waves dissapear) you need to use the biggest number in seconds - if you want to enhance slow wave activity on a time constant what number would you use.
