Seizures may occur due to which of the following conditions besides epilepsy?

• A. Epilepsy exclusively.
• B. Head injury exclusively.
• C. Sleep deprivation exclusively.
• D. Drug intoxication or hypoglycemia.

Answer: (D)

Seizures happen when brain electrical activity becomes abruptly abnormal, and they can be triggered by states that disrupt brain function beyond chronic epilepsy. Low blood glucose deprives brain cells of energy, making neurons more prone to firing in a chaotic, synchronized way that can produce a seizure. Drug intoxication can upset central nervous system activity or electrolyte balance, lowering the seizure threshold and precipitating convulsions even in those without epilepsy. Among the options, this combination best represents non-epileptic triggers for seizures. The other possibilities describe conditions that can be linked to seizures but aren’t universal or exclusive triggers—head injury can cause seizures after trauma, and sleep deprivation can increase risk in some people, but they’re not the clear, direct non-epileptic trigger highlighted here.
