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
