HYPERVENTILATION result - Hypocapnia: state of reduced carbon dioxide in the blood Photoparoxysmal response - EEG response to light with spikes, spike-wave discharge and/or intermittent slow waves Input impedance should be - very high According to the Guidelines, how many bits of resolution is required? - 11 Which of the following is the WORST prognostic feature in the EEG of a comatose patient? - monorhythmic tracing without variability SMALL SHARP SPIKES are also called - Benign Epileptiform Transients of Sleep (BETS) HYPSARRHYTHMIA shows - Disorganized, continuous high voltage slow waves with interspersed multifocal spike waves A seizure discharge arising from the right frontal lobe is likely to be characterized clinically by - deviation of head and eyes What is most important when evaluating the background activity? - Record the maximal state of alertness High voltage theta or delta waves, commonly seen in children 8-14 years, accentuated by hyperventilation: - Posterior Slow Waves of Youth (PSWY) A stroke which results in only LEFT leg weakness most likely involves which of the following arteries? - The RIGHT anterior cerebral artery Rare 6-11 hz negative sharp arciform waves, most commonly seen in adults over 30 years in the mid-temporal regions. - Wickets A prolonged series of generalized convulsions without any period of consciousness between them is referred to as - status epilepticus What differentiates Lambda and POSTS - Occurs with eyes open If the Low Frequency Filter is changed from I Hz to 5 Hz, how will a 2 Hz slow wave be affected? - It will be significantly attenuated Creuetzfeldt-Jakob disease EEG shows - GPDs/GPEDS Mu Rhythm is a frequency of - 8-10 Hz In which of the following conditions are periodic lateralized epileptiform discharges most likely? - Herpes simplex encephalitis Photic induced epileptiform discharges are most likely associated with - barbiturate withdrawal Subacute sclerosing panecephalitis is associated with - Measles Seizures commonly result from withdrawal of which of the following? - Alcohol At what conceptional age is a delta brush pattern primarily seen? - 32 to 34 weeks An electrographic seizure is characterized by - Episodic rhythmic activity Which of the following occurs during a typical absence seizure? - Impaired consciousness What is the term that describes failure of the alpha rhythm to attenuate with eye opening? - Bancaud's Phenomenon INFANTILE SPASMS EEG shows - Electrodecremental Events Slow sampling rate may cause fast frequencies to appear slower: - aliasing The polarity convention for EEG states that the deflection is up if input - I is more negative than input 2 The EEG pattern of hypsarrhythmia is usually associated with - infantile spasms An EEG obtained within 24 hours following
