Done 2/28/12, showing no more infantile spasms.
CLINICAL: 9-month-old with a severe CNS dysgenesis and infantile spasm with good level response to ACTH. Other medications include Topamax.
TECHNIQUE: 16 channel routine EEG.
INTERPRETATION: Recording begins with the baby appearing awake. There is a moderate amplitude theta and delta showing mildly abnormal distribution and lack appropriate gradient. There is no effect of strobe light stimulation. Sleep is recorded after 20 minutes. There is during sleep, frequent high amplitude rhythmic beta from the right posterior quadrant. It is seen independently as well from the left posterior leads. Sleep architecture also is abnormal with no spindles or vertex waves. There is a high amplitude theta and delta polymorphic in nature. The study, however, contains no epileptiform abnormally.
IMPRESSION: Continued abnormal EEG due to excessive slowing and relative suppression of physiologic activity as well as unusual beta in posterior derivations consistent with a history of cortical dysplasia . Epileptiform activity is now absent pronounced interval improvement.
