Which seizure type is described as sudden loss of consciousness with falling without movements and possible injury?

• A. a myoclonic seizure
• B. an absent seizure
• C. a myoclonic atonic seizure
• D. a focal seizure with impairment of consciousness

Answer: (C)

The main idea is recognizing how different seizure types affect muscle tone and consciousness. Sudden loss of muscle tone causing a collapse with little or no movement at the moment of the fall fits an atonic event. When this abrupt drop in tone occurs in the setting of brief myoclonic activity or alongside it, the pattern is described as myoclonic-atonic seizures. This explains both the sudden fall and the potential for injury, and it matches the scenario of falling with minimal movements rather than prominent convulsions. In contrast, a myoclonic seizure involves brief shock-like jerks with preservation of postural control; an absence seizure features brief cessation of awareness without a fall; a focal seizure with impairment of consciousness would typically have focal signs or automatisms and not present as a sudden drop with little movement.
