Understand the real-world incidences of and discontinuations due to the behavioral adverse events (BAEs) of irritability, anger, and aggression in patients with epilepsy treated with brivaracetam (BRV), levetiracetam (LEV), perampanel (PER), and topiramate (TPM), and BAEs in patients switching from LEV to BRV. 
Tolerability data from randomized, controlled trials provide only a glimpse into the incidence of BAEs in the real world as patients with comorbidities or other risk factors for these events are often excluded. Observational postmarketing studies may fill this gap, but have not been summarized. 

A systematic review of published literature using the Cochrane Library, PubMed/MEDLINE, and Embase was performed to identify real-world studies reporting incidences of irritability, anger, or aggression with BRV, LEV, PER, or TPM in adults with epilepsy either as discrete outcomes or adverse events. The incidences and discontinuation due to each, as well as BAEs in patients switching from LEV to BRV, were summarized. Where possible, weighted means were calculated, but not statistically compared.

A total of 1500 records were identified, and 44 published articles (42 studies) met the inclusion criteria. While a wide range of results was reported across studies, weighted mean incidences were: 5.6%, 9.9%, 12.3%, and 3.1% for BRV, LEV, PER, and TPM, respectively, for irritability; 3.3%*, 2.5%, 2.0%, and 0.2%* for anger; and 2.5%, 2.6%, 4.4%, and 0.5%* for aggression. Weighted mean discontinuation rates were: 0.8%*, 3.4%, 3.0%, and 2.2% for irritability and 0.8%*, 2.4%, 9.2%, and 1.2%* for aggression. There were no discontinuations for anger. Switching from LEV to BRV led to improvement of BAEs in 33.3% to 83.0% of patients. *denotes only 1 study. 

Differences in methods, BAE definitions, and populations across studies make a conclusion difficult. However, switching from LEV to BRV appears to result in improvement of BAEs.
