Historically seizures were classified basically as petit mal and grand mal. Sometime back in antiquity (maybe some thirty years ago which is ancient history in neurology) people began to realize that there were MOTOR seizures which did not go on to be complete grand mal seizures but they were certainly "more complex" than petit mal seizures (which aren't so simple by the way). Hence the name ... the seizures involve a stereotyped motor movement occuring the same way each time followed by at least an instant of utter confusion and also accompanied by the patient's unawareness of the event.

As a general rule new medications can cause TRANSIENT side effects of fatigue and nausea but if these persist, then you should notify your doctor who usually can try a different medication.
