MIDTERM EXAM NORMAL ELECTROENCEPHALOGRAPHY
QUESTIONS AND ANSWERS 100% PASS



Electromyogram - ✔✔Placed on the submental muscle under the chin, these record oral-lingual-

pharyngeal muscle movement used in sleep staging (EMG can also be placed on limbs to record and

correlate with EEG))


Respiration effort and nasal/oral airflow - ✔✔used in sleep staging, to characterize any apnea, and

identify respiratory movement artifacts recorded by EEG electrodes


Electrocardiogram (ECG or EKG) - ✔✔Record heart beats that may be recorded by EEG electrodes and

assess heart rate and rhythm


Oxygen saturation (monitored as a waveform or noted by the technologist) - ✔✔to assess the impact of

apnea events of oxygen levels in the blood


ELectrooculogram - ✔✔Record horizontal and vertical eye movements needed for sleep staging in

neonates


Rapidly changing background activity - ✔✔holoprosencephaly


periodic hypsarrhythmia in term infants - ✔✔Nonketotic hyperglycemia, other inborn errors or

metabolims and genetically determined encephalopathties


Periodic rolandic sharp waves - ✔✔Intraventricular hemorrhages (IVH) or periventricular Leukomlacia


Periodic Lateralized Epileptiform Discharges - ✔✔herpes simplex virus encephalitis


electrical only seizures - ✔✔are electrographic seizures without clinical events that correlate to the

activity

Clinical only seizures - ✔✔are without any correlated EEG


electroclinical seizures (aka: ictal activity) - ✔✔have clinical and electrographic events that correlate in

time


An EEG clinical interpretation is based on - ✔✔- Correlated clinical history


-Technical analysis of EEG


conceptual age (CA) which is used in EEG is calculated as - ✔✔Last Menstrual period of the mother plus

2 weeks


external dyschronism in a neonate indicates - ✔✔discerpancies between clinically detrmined CA and

developmental EEG features which can be an indication of micalculation of CA or evidence of brain

dysfunction


Neonatal EEG recordings vary based on irritability of the neonate, and other factors but the typical

minimum duration of a neonatal EEG is - ✔✔1 hour


how does a neonatal EEG differ from EEG recordings in other stages of life - ✔✔The Neonatal EEG is

rapidly evolving due to the rapid rate of cerebral development in the neonatal period


some labs apply the full 10-20 system of electrodes on neonates and other labs use a modified placement

system what are some of the reasons for using a modified system - ✔✔-The size of a neonatal head is so

small as to the place the full 10-20 placement quite close and record overlapping electrical fields.


- The neonatal frontal lobe does not extend as far into the forehead region as older children or adults


the character of the background activity, the presence of wake-sleep stages, specific waveforms and

pattern make up the _______________ of the neonatal EEG. - ✔✔Graphoelements


what two things must be considered before interpretation of a neonatal EEG recording - ✔✔CA and state

of consciousness
