Final answer:
Simple seizures show no loss of consciousness, whereas complex seizures show altered or loss of consciousness.
Step-by-step explanation:
Simple seizures show no loss of consciousness, whereas complex seizures show altered consciousness or loss of consciousness. Complex seizures involve a larger area of the brain and can cause changes in behavior or awareness. Examples of complex seizures include focal impaired awareness seizures, where the person may appear dazed or confused, and absence seizures, where the person briefly loses awareness.
