Medication use for epilepsy prevention after stroke or traumatic brain injury

Epilepsy is a common condition that requires treatment with antiepileptic medications and may occur after stroke or traumatic brain injury. It is possible to use various medications to prevent occurrence of epileptical seizures after stroke or traumatic brain injury.

SBU Enquiry Service

Consists of structured literature searches to highlight studies that can address questions received by the SBU Enquiry Service from Swedish healthcare or social service providers. We assess the risk of bias in systematic reviews and when needed also quality and transferability of results in health economic studies. Relevant references are compiled by an SBU staff member, in consultation with an external expert when needed.

Question

What systematic reviews have been published regarding the use of medications to prevent epilepsy after stroke or traumatic brain injury?

Method

A systematic literature search was performed using the following databases: MedLine (Ovid) and Scopus.

Two authors independently assessed the abstracts of all identified studies.

Risk of bias in relevant systematic reviews was assessed using an assessment tool based on AMSTAR.

Identified literature

One relevant systematic review with moderate risk of bias was identified [1]. The results and conclusions are presented in Table 1. In 5 relevant systematic reviews, the risk of bias was considered to be high, therefore the results and conclusions are not reported [2] [3] [4] [5] [6].

Table 1 Systematic review with moderate risk of bias.
Included study Population, Intervention, Control Outcome and Results
Chang et al., Antiepileptic drugs for the primary and secondary prevention of seizures after stroke (Review), 2022. [1]
2 randomised double-blind studies (n=72; n=856) Population:
Participants with either ischaemic or haemorrhagic stroke

Intervention:
Use of antiepileptic drugs (AEDs) such as diazepam and valproic acid.

Control:
Placebo
Primary prophylaxis of post-stroke seizure with AEDs (2 studies, n=856):
RR=0.65 (95% CI, 0.34 to 1.26)
Authors' conclusion:
There is insufficient evidence to support the routine use of AEDs on the primary and secondary prevention of seizures after stroke. Further well-conducted studies are warranted for this important clinical problem.
