EEG Board Prep Questions And Answers

EEG Board Prep Questions And Answers You are called to do an EEG on a patient who was found down for an unknown amount of time. Based on your findings, you decided to perform cerebral death protocol via your labs policy. The sensitivity should be increased to 2 uv/mm A recording directly from the brain Electrocorticorgraphy Tacys Sachs disease is associated with Cherry red spots in the eyes You are recording in a longitudinal (double banana) montage. You see a spike discharge phase reverse at C4 and T4. In this case the true localization of the spike can best be see in a transverse montage If the time (horizontal) scale is changed from 30mm/sec to 15mm/sec, the 6 hertz activity becomes there is no frequency change but the activity appears faster Which of the follow drugs show the most observable effects on the EEG? Benzodiaepines The notch filter can distort spikes and should only be used when other measures to reduce ____ interference fail 60Hz Lambda waves can be associated with saccadic eye movement Wernickes Encephalopathy can be cause by Thiamine deficiency During a bipolar recording, you notice sharp activity from F7-T3 that shows an upward deflection, T3-T5 shows no activity, and T5-O1 shows a downward deflection. Which statement below best represents the above scenario? Equipotential at T3 and T5 A characteristic of this disease is high amplitude spikes in the occipital region, time locked with a slow photic stimulus rate in young children Batten's disease Which are of the CNS contains nucli of the cranial nerves III to XII? Brain stem This is located in the frontal lobe primary motor strip EPSP causes Depolarization A patient has hepatic encephalopathy. The EEG is most likely to show Triphasic waves You are performing an EEG on a person who has Alzheimer's disease, but is is the very early stages. You are most likely to see this on the EEG normal activity The amplitude of a theta wave on the left temporal is 65uV, and the amplitude of a theta wave at the same time on the right temporal is 25 uV. This is called
