I would agree with your thought that these episodes are seizures. After starting medications full blown attacks may not come and such aborted attacks may occur. However these episodes also need to be controlled for a good epilepsy
management. Either current medications have to be hiked up or additional drugs have to be added to control these attacks also. Since EEG is abnormal so possibility of seizures is high. MRI
and other scans may come normal in many epilepsy patients.
