Why One Year Without Seizures Matters In Epilepsy

What was studied

This study asked a panel of 28 stakeholders from European Union countries and the UK to give their views about what "seizure freedom" should mean in epilepsy care and research, and why it matters. The panel included epileptologists, neurologists, nurses, patient advocacy representatives, and health economics experts.

The researchers used a three-round Delphi process, which is a structured way to build expert agreement through repeated questionnaires. The questions covered clinical, social, and economic aspects of seizure freedom.

What they found

The panel reached high consensus that seizure freedom should mean having no seizures for 1 year or longer. They also agreed that seizure freedom is an important primary endpoint in studies of people with newly diagnosed epilepsy and in epilepsy surgery.

For people with drug-resistant epilepsy, the panel agreed that seizure freedom should not be the only primary endpoint, suggesting that other outcomes also matter in this group. The experts identified improved quality of life, psychological well-being, and functional independence as key benefits of seizure freedom. They also rated the economic and societal effects of uncontrolled seizures as highly significant and impactful.

Limits of the evidence

This was an expert consensus study, not a study that followed patients or tested a treatment. It shows what this panel agreed on, but it cannot show from patient data that seizure freedom leads to all of the benefits discussed.

The panel was small, with 28 participants, and it reflected views from Europe and the UK in resource-rich settings. Results may not fully apply to other regions, health systems, or all people with epilepsy. The abstract also does not give detailed information about how strongly every group agreed on each point.

For families and caregivers

For families, this study supports the idea that stopping seizures is a major goal of epilepsy care and that experts view it as important for daily life and well-being. It also suggests that doctors and researchers may use a clearer definition of seizure freedom in the future.

At the same time, the study recognizes that for some people, especially those with drug-resistant epilepsy, success may include more than complete seizure freedom. That may help families have more balanced conversations about treatment goals and what outcomes matter most to the person with epilepsy.

What to watch next

Patient-based studies could help show how 1 year of seizure freedom relates to quality of life, independence, and costs in different epilepsy groups.
