Which factor increases the risk of withdrawal seizures when benzodiazepines are discontinued?

Which factor increases the risk of withdrawal seizures when benzodiazepines are discontinued?

• A. Risk decreases with longer treatment duration.
• B. Risk is unrelated to duration of treatment.
• C. Withdrawal risk is only related to dose, not duration.
• D. Risk increases with longer treatment duration.

Answer: (D)

Prolonged use of benzodiazepines leads to dependence, and withdrawal seizures occur because the brain adapts to the presence of the drug over time. With longer exposure, the brain makes more substantial neuroadaptive changes in the GABAergic system and related excitatory pathways. When the medication is stopped, these adaptations rebound, causing a surge in neural excitability that can manifest as seizures. Therefore, the risk of withdrawal seizures increases as the duration of treatment lengthens, especially if cessation is abrupt. Dosing and the specific benzodiazepine matter, but duration of therapy is a key factor: longer treatment raises the likelihood of withdrawal-related seizures.
