The correct answer is B. This patient has complex partial seizures, which are characterized by automatisms ("picking" movements with hands, chewing, swallowing), that are preceded by an aura. The sequence of events is as follows: aura, behavioral arrest or a motionless stare, automatisms, and postictal confusion. The patient has an impairment of consciousness. These seizures occur in a focal region of the brain, often the temporal lobe.
Absence seizures (choice A), also called petit mal seizures, are generalized seizures that consist of a brief loss of consciousness and automatisms. Postural control is maintained. There is no postictal confusion.
Generalized tonic-clonic seizures (choice C) are characterized by a sudden contraction of the muscles followed by periods of contraction and relaxation, and finally, relaxation. There is postictal unresponsiveness, excess salivation, and bowel and bladder incontinence.
Myoclonic seizures (choice D) consist of the sudden contraction of one part of the body or may involve the entire body. It is caused by cortical dysfunction.
Simple partial seizures (choice E) are characterized by motor, autonomic, sensory, or psychic symptoms. An aura may precede the seizure. Consciousness is maintained.
