Awareness during a seizure is defined as the person being fully aware of themselves and their environment throughout the seizure, even if immobile. If awareness is impaired at any point during the seizure, the seizure is a focal impaired awareness seizure. The degree of loss of awareness may vary. The terms 'complex partial seizure' and 'focal dyscognitive seizure' were previously used to denote a focal impaired awareness seizure.
