LONG-TERM EEG-VIDEO MONITORING COMA EPILEPSY LABORATORY CLINICAL NEUROPHYSIOLOGY LABORATORIES DEPARTMENT OF NEUROLOGY UNIVERSITY OF MICHIGAN Patient: @NAME@ Age: @AGE@ Dates of recording: @ED@ through *** MRN: @MRN@ Referring Physician: @REFPROV@ History: The patient is a @AGE@ {gender list:22183} with a history of ***. This long-term video-EEG monitoring study was performed in order to evaluate for focal and/or epileptiform abnormalities and subclinical seizures. The patient {IS/IS NOT:27046} on neuroactive medications. @NAME@ @CMEDPBRAND@ Technical Description: This is a 21 channel digital EEG recording with timelocked video. Electrodes were placed in accordance with the 10-20 International System of Electrode Placement. Single lead EKG monitoring as well as temporal electrodes (T1 and T2) were included. Baseline EEG Recording: A formal baseline recording was not obtained. Day 1 - 10/7/2016, starting at *** Interictal EEG Samples: This recording was obtained {state:304014064} The background was {Symmetry:304014032}. There {Was/Was not:304025122} a posterior dominant rhythm of *** Hz, *** uV that was {Rhythm:304014033}. The predominant background frequency was in the {Frequency:304025124} band(s) and was of {Voltage:304025123} voltage. There {Was/Was not:304025122} an anterior-posterior gradient. There {Was/Was not:304025122} background variability. Reactivity to stimuli was {Present/Not present:304025125}. {Symmetry:304014032} V waves, K complexes, and sleep spindles were {Present/Not present:304025125}. The background was {Continuous:304025126}. ***BURST SUPPRESSION***The background was consistent with burst suppression. The bursts lasted *** seconds with interburst intervals of *** seconds. The bursts were {contour:304025127}. The predominant background frequency seen in the bursts was in the {Frequency:304025124} band(s) and was of {Voltage:304025123} voltage. ***PDs***There were {prev:304025128} *** Hz - *** Hz {phase:304025129}, {contour:304025127}, {amp:304025131} voltage, {lat:304025132} periodic discharges (***PDs) with {polarity:304025133}. These had superimposed {pdmod:304025134} activity and were consistent with ***PDs +***. These {were/were not:304025135} induced by {stimuli:304025136} stimuli. These {fluct:304025137}. ***RDA***There was {prev:304025128} *** Hz - *** Hz, {amp:304025131} voltage, {lat:304025132} rhythmic delta activity (***RDA). This activity had superimposed {activity:304025145} activity and was consistent with ***RDA +***. This activity {Was/Was not:304025122} induced by {stimuli:304025136} stimuli and {fluct:304025137}. ***SW***There were {prev:304025128} *** Hz - *** Hz {phase:304025129}, {contour:304025127}, {amp:304025131} voltage, {lat:304025132} spike waves (***SWs). These {were/were not:304025135} induced by {stimuli:304025136} stimuli. These {fluct:304025137}. ***triphasics***There were {prev:304025128} *** Hz - *** Hz triphasic waves {triph:304025139}. These were {triph2:304025140}. Ictal EEG Recording / Patient Events: During this period the patient had no events or seizures. Summary: During this day of recording *** seizures were recorded. The interictal EEG was abnormal due to: 1. *** 2. *** 3. *** Monitoring was continued in order to evaluate for subclinical seizures. The EKG channel revealed no abnormalities. @MECREDENTIALNOREFRESH@ Epilepsy Fellow Clinical Code(s): {Diagnosis Codes:304025144} This EEG was reviewed with epilepsy attending {attending:304025143}. The above findings were conveyed to the primary team at regular intervals. Please note this is a preliminary report and updated on a daily basis. The final report will have a summary of behavior and electrographic findings with clinical correlation
