Diplopia Double vision Which normal waveform is NOT typically seen in the posterior leads? (Wickets, photic driving, Lambda, POSTS) Wickets The EEG of a patient with Down's syndrome is most likely to show: normal activity The sharpness of the frequency response curve is determined by the filter ___ rolloff A lesion of the uncus may result in olfactory hallucinations Delta brushes are seen in what type of patients premature infants Changes in personality are most likely associated with tumors of the __ lobe frontal lobe What type of seizure is NOT associated with Lennox Gastaut syndrome complex seizures Which of the following is most closely related to the measurement of voltage in relation to current and resistance Ohms law A meningioma is usually -infiltrating, -metastatic, -rapid growing -encapsulated impedance can best be described as -current produced by a wire coil in a magnetic field -ability to store an electrical charge -resistance to alternating current -resistance to direct current ...resistance to alternating current What normal activity would be seen most prominently at the C3 or C4 electrode position? -POSTS -Mu -Alpha -FIRDA Mu It is common for FIRDA to -be considered normal in adults age 30 to 50 -be confused with nystagmus -react to stimulation -have spikes intermixed ...be confused with nystagmus Voltage Resolution is correlated with -Bandwith -Sample rate -Analog to digital converter Analog to digital converter A large lesion at the optic chiasm will likely produce.. complete visual loss What EEG finding indicates the worst prognosis in patients with cerebral hemorrhages? burst suppression pattern The neurological examination is most likely to be abnormal in patients with -Lennox Gastaut -juvenile myoclonic epilepsy -Rolandic epilepsy Lennox gastaut Through what opening do the lateral ventricles merge with the third ventricle? Foramen of monroe What enviornmental factors enhance LAMDBA? Scanning high complexity visual scene Compared to recordings from adult patients, Vertex Waves in pediatric EEG recordings are generally Sharper Periodic lateralized epileptiform discharges are most likely associated with which condition Herpes simplex encephalitis In patients with myoclonic epilepsy of Janz, seizures are most likely to occur: In the morning During which of the following types of seizures would a patient be likely to experience deja vu? -myoclonic -complex partial -generalized non convulsive -atonic ...complex partial A common electrographic correlate of a seizure -irregular polymorphic delta -rhythmic activity -single bifrontal spikes -intermittent temporal spikes rhythmic activity Which mathematically converts the time function into a sine wave of different frequencies -Fast fourier transform -impedance meter -A/D converter -Differential amplifier Fast fourier transform When a large amount of electrode paste is used to hold EEG electrodes in place, the total recording area will be the -scalp surface area of the paste -diameter of the EEG electrode -inner surface area of the electrode -inner plus outer surface area of the electrode total scalp surface area of the paste Photic induced epileptiform discharges are most likely associated with -meningitis -barbiturate withdrawal -hepatic encephalopathy -down syndrome barbiturate withdrawal What clinical signs are expected to be seen if a patient has a stroke involving the left anterior cerebral artery? -left lower extremity sensory loss -right homonymous hemianopsia -left homonymous hemianopsia -right lower extremity sensory loss Right lower extremity sensory loss Clipping of the waveforms occurs when: the signal is outside the range of the digitizer Using the International 10-20 electrode placements, if the distance from Fp2 to F4 is 5.5 cm, what is the distance from P4 to 02? 5.5cm CREUTZFELDT-JAKOB DISEASE pattern: Periodic sharp waves Clinical semiology is a way to describe: behaviors during patient events Which of the following would indiciate the best prognosis in a comatose patient? -spindle coma -electrographic changes indicating wakefulness and sleep -generalized low amplitude delta with no background -generalized suppression of EEG Electrographic changes indicating wakefulness and sleep. What is indicated by the presence of unilateral Babinski Signs? -Pyramidal tract dysfunction -cerebellar dysfunction -homonymous hemianopsia -tic Doulourex Pyramidal tract dysfunction What normal activity would be seen most prominently at the C3 or C4 electrode postion? -FIRDA -Mu -POSTs -Alpha Mu
