Which seizure is marked by brief loss of muscle tone and can be mistaken for fainting?

• A. Absence
• B. Myoclonic
• C. Generalized
• D. Atonic

Answer: (D)

Atonic seizures are defined by a sudden loss of muscle tone, causing a brief collapse or head drop. This abrupt drop in tone is what makes them easy to mistake for fainting, since both can result in a sudden loss of postural control. Absence seizures involve momentary brief impairment of consciousness with a blank stare and typically no actual collapse. Myoclonic seizures produce brief, sudden jerks of muscles without a true loss of tone or collapse. Generalized seizures involve widespread brain activity that can include loss of consciousness and convulsions, not just a brief drop in tone. So, the scenario described aligns best with an atonic seizure.
