Substance withdrawal, particularly from alcohol or sedatives, lowers the seizure threshold and is well-documented to trigger acute symptomatic seizures, including generalized tonic-clonic (grand mal) seizures.

The analysis

The retrieved literature consistently supports the claim that substance withdrawal (specifically alcohol and CNS depressants) can trigger acute symptomatic seizures. Paper [1] includes drug and alcohol withdrawal in its definition of acute symptomatic seizures. Paper [5] details that alcohol withdrawal lowers the seizure threshold and poses a major risk for seizures. Paper [8] explicitly studies patients experiencing generalized tonic-clonic seizures due to alcohol withdrawal.
