Which class of medication is used to prevent or reduce seizures in neurological disorders such as brain tumors, meningitis, or epilepsy?

• A. Anticonvulsants (Class)
• B. Diuretics
• C. Beta blockers
• D. Corticosteroids

Answer: (A)

Preventing seizures relies on medications that directly dampen abnormal brain activity. Anticonvulsants, the class used to prevent or reduce seizures, work by stabilizing neuronal membranes and reducing hyperexcitability through various mechanisms—enhancing inhibitory GABA signaling, blocking voltage-gated sodium channels to limit repetitive firing, inhibiting calcium channels to reduce burst activity, or lowering excitatory glutamate effects. This makes them the primary choice for controlling seizures in epilepsy and for minimizing seizure risk in brain tumors or meningitis. Diuretics mainly reduce fluid build-up, beta blockers affect heart and vascular function, and corticosteroids address inflammation and swelling but do not provide direct seizure prophylaxis.
