Seizures may occur due to a brainstem hemorrhage for several reasons, First, significant edema following a brainstem hemorrhage, combined with the mass effect of the hemorrhage itself, can lead to substantial compression of the brainstem, potentially resulting in tonic seizures. Second, the irritation from the hemorrhage could trigger symptomatic epilepsy, with the patient possibly experiencing partial new epileptic seizures that evolve into generalized tonic-clonic seizures. Third, the brainstem hemorrhage might cause high fever, which could induce febrile convulsions, also leading to seizures. Fourth, the treatment of brainstem hemorrhage often involves the use of high doses of diuretics. If severe dehydration occurs, it can lead to a state of excessive dehydration, electrolyte imbalance, and hyperosmolarity; high sodium levels might also trigger seizures.
