Since that time, the child has been doing fairly well. However, he has been mentally slow and has been in a special education class during most of his school career. Anteriorly, lower amplitude activity of mixed frequencies is seen. As the recording progresses, the patient becomes drowsy with generalized symmetric increased slowing of the background activity associated with development of vertex sharp waves. Stage 2 is reached later in the recording with noted symmetric sleep spindles and K-complexes.
Hyperventilation produces a minimal generalized disorganization of the background activity.
Photic stimulation produces a bioccipital driving response. Abnormal EEG in the wake, drowsy, and stage 2 sleep states due to the presence of focal left temporal sharp waves and rhythmic theta slowing. This finding is potentially epileptiform from an electrographic viewpoint and could correlate best with a partial seizer disorder. History of abuse, would not be surprised if psychiatric abnormalities were pressed as well speech is ok without dysarthria. Does not state what cause of this may be.
