One seizure does not mean that a person has epilepsy. People with epilepsy have repeated seizures.
Many people experience a single seizure during their life. Typically, it will be provoked by a factor such as extreme stress, sleep deprivation, or excessive alcohol intake. As long as the provoking factor is avoided in the future, most people won't have another seizure. Nine out of 10 people who have these provoked seizures do not go on to develop "true" epilepsy - that is, repeated, unprovoked seizures. The risk that a child who has febrile seizures developing epilepsy is even lower - about 2 in a 100.
Consult your Physician
If you think you have had a seizure and have not had one before, you may need to see a Neurologist. Not all sudden changes in behavior are seizures. It is important to have your condition properly diagnosed.
Epilepsy treatment strategies
When investigations have found a specific cause of seizures, such as a brain abscess or low blood sugar levels, Neurologists will try to treat the underlying cause to prevent seizures.
