Age-related criteria Flashcards
what are some EEG changes associated with normal aging?
Slowing of PDR
Increase in temporal slowing
Bursts of Generalized rhythmic delta during drowsiness.
Diffuse lower voltage
Trace discontinu which appears in a 42 week CA neonate is considered? A/N?
abnormal, should be replaced by TA by 37-40 weeks
What is the recommended minimum length of continuous EEG recording for neonates at high risk for seizures?
24 hours, continuing until seizure- free for 24 hours
When monitoring neonates, modified placement of which electrodes allows the best visualization of background activity?
Frontopolar electrodes. FP3/FP4 sometimes used
at what age do most children reach a PDR of 8Hz
36 months (3 years)
What is the most common cause of seizures in neonates?
hypoxic-ischemic encephalopathy (HIE)
What is the fastest growing epilepsy population?

c) 33-34 weeks
d) at 35 weeks
B 30-32 weeks
For neonates, how is the postmenstrual age (PMA) determined/calculated?
PMA= GA + CA
What is the duration of a sleep-wake cycle for a term infant?
Pre-term <35 PMA: 30-50 minutes
Pre-term >35 PMA: 50 to 65 minutes
Term: 3 to 4 hours
What are the behavioral states for neonates?
Awake
Asleep
Transitional Sleep
