Tuberous sclerosis complex (TSC) is associated with a high risk of early-onset epilepsy and developmental delay. Recently, EEG monitoring in infants with TSC and preventive antiepileptogenic treatment have been proposed to improve epilepsy and neurodevelopmental outcome. We explored how recent studies and recommendations regarding EEG monitoring and preventive epilepsy treatment have influenced the clinical practice of epilepsy management among children with TSC.
Methods: A survey on the epilepsy management approach in infants with TSC was sent by e-mail to 165 clinicians who actively participated in TSC international research conferences in years 2016 - 2019. Additionally, the e-mail addresses of TSC referral centers were collected from national TSC organizations. The survey was also distributed in the American Epilepsy Society newsletter. Only responses from centers providing neurological care for children with TSC were included in the study.
Results: Sixty-one responses from 23 countries were analyzed. Sixty respondents answered questions concerning infants, and 57 of 60 respondents (95%) perform at least one EEG study before epilepsy onset and 42 (70.0%) conduct regular EEG monitoring. Most of the clinicians perform video EEG (42/61, 68.8%). Overall, 51.7% of respondents, mostly from Europe, Australia, and South America, endorse preventive antiepileptic treatment in infants with TSC. Vigabatrin is a preferred drug in patients younger than two years old for both focal (61.7%) and generalized (56.7%) seizures.
Conclusions: Despite the lack of published results of randomized trials, the concepts of preseizure EEG monitoring and epilepsy prevention are already being implemented in the majority of surveyed centers.
