Gliomas- tumors arising from glial cells (supportive tissue neurons are imbedded in),
1._____________(40's,50's, focal spikes and sharps), 2._________(lining central canal/ventricles, more
common children) , 3.________(focal spike EEG, most common, focal or gen sz),
4.____________("butterfly"-invades via corpus callosum, sz, memory loss, headache, malignant,
behavior change), 5.___________ (rapid, children, roof 4th ventricle, listless, vomit, gait, dizzy). Spread
in fingerlike fashion-infiltration makes surgical removal impossible. - ANSWER-1. Oliogodendroglial
2. ependymal
3. astrocytoma
4. gliobastoma multiforme
5. medulloblastomas
What is ictal EEG of GTC? - ANSWER-Ictal EEG about 10 Hz of gen polyspikes during tonic, and then 1 Hz
spike and wave during clonic
_________ _______ is where body's immune system attacks part of PNS, nerves lose myelin sheath. The
first symptoms of this disorder include varying degrees of weakness or tingling sensations in the legs.

Often, weakness and abnormal sensations spread to the arms and upper body. Can result in paralysis of
diaphragm - ANSWER-Guillain- Barre syndrome
________ is a tumor made of cells normally found in area of body where it forms. Not malignant.
Doesn't metastasize, but can grow large and damage organ. Found with tuberous sclerosis. - ANSWER-
hamartoma
What is the foramen of munro/interventricular foramen ? - ANSWER-opening between lateral ventricles
to third ventricle
The _____________ is a tract of white matter connecting hippocampus with hypothalamus - ANSWER-
fornix
1. Fourteen and/or six Hz positive spikes occur in what region?
2. When can fourteen and/or six Hz occur?
3. What is the best montage to view this in? - ANSWER-1. Occipital/ posterior temporal
2. drowsy/early sleep
3. contralateral ear reference
Frequency equation - ANSWER-Frequency=[(mm/paperspeed)]/1000
What EEG patterns with frontal lobe tumor? - ANSWER-FIRDA, focal slow, arrhythmic delta activity
Where are T1/T2 placed? - ANSWER-placed one third of the distance from external acoustic meatus to
outer canthus of the eye, 1 cm above the eye
With ______ disease, juvenile form has onset 6-8 yrs, sz often tonic-clonic or partial motor. EEG
progressive deterioration of background activity, multifocal abnormalities - ANSWER-Gaucher
With ______ _______, there is laughing. Disease of hypothalamic hamartomas manifesting with gelastic
seizures. This often evolves to a generalized epileptic encephalopathy with severe seizures and cognitive
and behavioral decline - ANSWER-gelastic seizure
, 3|Page
What EEG patterns can be seen with head trauma? - ANSWER-EEG may be normal, slightly more gen
theta, slow waves, burst suppression, spindle coma, alpha coma. Hard to call abnormal if no pre-injury
EEG
What is hemianopsia? - ANSWER-decreased vision in half visual field, on one side of vertical midline,
usually caused by single lesion, may be caused by stroke
What EEG can be expected with hemispheric white matter tumor? - ANSWER-continuous high amp, gen
PDA from destructive lesion
What EEG can be seen with hepatic encephalopathy? - ANSWER-EEG gen slow to triphasic waves
frontally predominant 1.5-3 Hz.
What EEG patterns would you see with Herpes Simplex Encephalitis? - ANSWER-EEG PLED's, often w/
temporal lobes. Temporal spikes and/or sharp waves at rate of one x 1-3 seconds
With _______ __________, the pt can't see to left out of either eye if right posterior cerebral artery,
vice-versa - ANSWER-homonymous hemianopsia
What are the contraindications for hyperventilation? - ANSWER-heart disease, CVA, sickle cell anemia,
COPD, extreme hypertension, subarachnoid hemorrhage
_______ has .5 to 3 Hz multifocal, asynchronous spikes, sharp and slow waves of 300 - 2000 uV. -
ANSWER-hypsarrhythmia
When do infantile spasms occur? - ANSWER-onset peaks 4-7 months, always before 1 yr
What are other names for infantile spasms? - ANSWER-West's Syndrome, jack-knife seizures, salaam
spasms
