Answer

The 2010 AHA/ASA guidelines do not offer recommendations on prophylactic anticonvulsants, but suggest that continuous EEG monitoring is probably indicated in patients with intracranial hemorrhage whose mental status is depressed out of proportion to the degree of brain injury

Prophylactic anticonvulsant therapy has been recommended in patients with lobar hemorrhages to reduce the risk of early seizures. One large, single-center study showed that prophylactic antiepileptic drugs significantly reduced the number of clinical seizures in these patients. [31]

In addition, AHA/ASA guidelines from 2012 suggest that prophylactic anticonvulsants may be considered for patients with aneurysmal subarachnoid hemorrhage. In such cases, however, anticonvulsant use should generally be limited to the immediate post-hemorrhagic period. Routine long-term use is not recommended, but it may be considered in patients with a prior seizure history, intracerebral hematoma, intractable hypertension, or infarction or aneurysm at the middle cerebral artery.
