Long-term outcomes
Seizure freedom, remission and resolved epilepsy are related ideas, but they are not interchangeable. The words matter because they can affect treatment decisions, driving, risk discussions and how someone understands their own diagnosis.
Central point: Being seizure-free does not automatically mean epilepsy has been cured, and the ILAE term “resolved” has a specific definition.
What does seizure freedom mean?
In everyday clinical use, seizure freedom usually means that no recognised epileptic seizures have occurred during a specified period. The length of that period matters. A person who has been seizure-free for 3 months and a person seizure-free for 8 years are both seizure-free at that moment, but their long-term recurrence risk and treatment decisions may be very different.
Research studies also use different definitions of seizure freedom, which is one reason percentages from different trials cannot always be compared directly.
What is remission?
Remission is a broader term used to describe a sustained period without seizures. There is no single universal duration that every study, service or legal system uses. Remission therefore needs context: how long seizure-free, whether antiseizure medication is still being taken, and what type of epilepsy the person has.
What does “resolved epilepsy” mean?
The ILAE operational definition says epilepsy may be considered resolved in someone who had an age-dependent epilepsy syndrome and is now beyond the relevant age range, or in someone who has remained seizure-free for the last 10 years and has taken no antiseizure medication for the last 5 years.
Resolved does not mean that recurrence is impossible. The ILAE deliberately avoided using the word “cure” because some residual recurrence risk can remain even after long seizure-free periods.
Can someone be seizure-free while still having epilepsy?
Yes. Many people become seizure-free because medication, surgery or another treatment is controlling seizures. The diagnosis does not automatically disappear when seizures stop. This is particularly important when treatment is still needed to maintain seizure control.
When is medication withdrawal considered?
NICE recommends that after a person has been seizure-free for 2 years, an individualised assessment should be carried out to estimate the risk of recurrence if antiseizure medication is discontinued. Two years is therefore a point for review, not a guarantee that stopping treatment is safe.
The decision should consider epilepsy type, syndrome, cause, EEG and imaging findings where relevant, previous seizure history, treatment history, lifestyle, driving, employment, pregnancy considerations and the person’s own priorities. Some syndromes and structural epilepsies carry a higher recurrence risk after withdrawal.
How is medication usually stopped?
If discontinuation is agreed, NICE recommends gradual reduction. For most antiseizure medicines this would typically be over at least 3 months, while benzodiazepines and barbiturates are usually reduced more slowly because of withdrawal risks. Medication should not be stopped suddenly unless a specialist has given a specific reason and plan.
What if a seizure happens after remission?
NICE recommends urgent reassessment after seizure recurrence following a period of remission. A recurrence can affect treatment, driving status and safety planning, and may prompt review of diagnosis, triggers, adherence, new illness or changes in the underlying epilepsy.
After epilepsy surgery
People who become seizure-free after surgery may still remain on antiseizure medication for a period. NICE advises that medication withdrawal after epilepsy surgery should be guided by the epilepsy surgery centre because recurrence risk depends on the operation, pathology, postoperative findings and individual history.
Driving and legal definitions are separate
Medical terms such as remission or resolved epilepsy do not automatically determine driving eligibility. Driving rules are jurisdiction-specific and use their own seizure-free intervals and conditions. In the UK, DVLA rules should be checked directly rather than inferred from the medical definition of remission.
