Which category of drugs is designed to help prevent convulsions in patients with neurological injury?

• A. Antidepressants
• B. Anticonvulsants (Class)
• C. Narcotics
• D. Proton pump inhibitors

Answer: (B)

When brain injury raises the risk of seizures, drugs that are designed to prevent convulsions are used. These anticonvulsants work by reducing the brain’s tendency to become overexcited. They stabilize nerve cell membranes and either enhance inhibitory signals (like GABA) or decrease excitatory signaling. This raises the seizure threshold and helps prevent the spread of abnormal electrical activity that leads to seizures.

Different anticonvulsants achieve this through various mechanisms—some boost GABAergic inhibition, others block voltage-gated sodium or calcium channels, and some modulate glutamate release. In practice, they’re used to prevent seizures after neurological injuries such as head trauma, stroke, infections, or tumors, with choice and duration tailored to the specific risk and context. Other drug classes listed don’t target seizure prevention in this way, which is why anticonvulsants are the correct category.
