Although the facts about epilepsy show there are several causes and types of epilepsy, the condition still isn’t completely understood by medical experts. However, if you’re hoping to get a good grasp of the details concerning how the disorder works and its impact on the world, this article covers ground on many of the world’s verified statistics on the topic.

General Epilepsy Statistics and Facts

Epilepsy Statistics - General

1. For an epilepsy diagnosis, at least two seizures must occur more than 24 hours apart.


For people suffering from active epilepsy, there’s a very high chance of experiencing at least two seizures with a 24-hour gap between occurrences. This can be controlled effectively by studying the patient’s symptoms and providing the right level of neurological treatment.

2. According to the World Health Organization’s epilepsy statistics, only 25% of epilepsy cases are preventable.


Of course, epilepsy is a dangerous disorder. This doesn’t mean the disease can’t be controlled or even prevented. Knowing the most useful preventive measures could greatly reduce how common the disorder has become.

3. A seizure can last up to 30 minutes or longer before risking permanent brain damage.

Seizures come in various types and a wide range of degrees. When a seizure lasts for longer than normal, it’s usually referred to as status epilepticus. If it lasts for 30 minutes or longer, it can lead to long-term brain damage. On top of that, epilepsy can cause death, statistics show. 

4. Epilepsy is more common in Latin America.


Regions of Latin America and some African countries have the highest prevalence rate of epilepsy today. Medical experts have provided means of treatment across the world, and by improving awareness, the public has taken great leaps ahead in fighting the health disorder.

6. People with epilepsy have a higher risk of premature death than those without.


Over time, medical experts have studied the ins and outs of epilepsy. From the facts on epilepsy laid out by the World Health Organization, the risk of premature death in people with active epilepsy is three times greater than it is among the general population. Active epilepsy means it’s been diagnosed, and the patient in question is undergoing treatment for it.

7. Within the period of 2010 to 2015, the number of people diagnosed with epilepsy grew from 2.3 million to 3 million in the US. 


Is epilepsy becoming more common? It only took five years for the number of diagnosed epilepsy cases to see an increase of over 23%. Medical experts have studied this and concluded that the health disorder will continue to grow. 

8. 1 in 10 people will have an unprovoked seizure in their lifetime.

(Epilepsy Foundation) 

Medical researchers have studied seizures and claim that about 10% of the population will experience an unprovoked seizure. A study that focused on weeding out the epilepsy facts and myths showed that epilepsy is often what causes seizures. From the research put forward by leading medical bodies, it’s been determined that epilepsy is one of the known major causes of seizures. Other causes include a high fever brought about by an infection such as meningitis. 

9. Epilepsy can be caused by low oxygen during birth, as well as head and brain injuries. 


What are the main causes of epilepsy? Investigating what causes epilepsy, it’s been found that something as common as an injury to the head can play a big part.

13. What gender is most affected by Epilepsy? Epilepsy syndromes are more commonly found in males than in females. 


This issue has often been debated by medical experts. Today, top studies show that although men and women have highly similar risks of having an epileptic seizure, men still retain a higher risk of developing the syndrome. However, epilepsy statistics from 2018 showed that syndromes of photosensitive epilepsy are more common in females.

14. 56% of adults with epilepsy experience seizures even after undergoing treatment.

15. 50%–60% of children experiencing seizures will be free from them in adulthood.


A study carried out by the epilepsy foundation known as the Child Neurology Foundation, showed that about 50%–60% of kids with seizures will outgrow them. Put simply, these child epilepsy statistics indicate that they won’t experience seizures later on in their lives.

16. 70% of the people who have epilepsy would no longer have seizures if their condition was diagnosed and treated properly.

Today, epilepsy is a common disorder in our world, and having enough treatment methods is a good way to improve people’s lives, even save them. Not to mention, the epilepsy statistics worldwide from 2017 showed that medical experts have produced various forms of anti-seizure medication. They’ve been developed alongside a collection of other treatment forms to ensure that other effects of the health disorder are also managed.

21. California has the highest number of epilepsy disorder cases in the US. 


The CDC has epilepsy prevalence data showing that this populous state has the most cases of the disorder. The CDC estimates that it has a whopping 367,900 recorded cases in adults. The state with the lowest number of cases is Wyoming with about 5,100. 

22. Focal seizures, which last for a minute or two, are responsible for about 60% of all epileptic seizures.

23. The epilepsy facts also show that generalized seizures account for 30% of all epileptic seizures.


Generalized seizures usually develop from focal seizures. Today, they are known to include tonic seizures, partial seizures, grand mal seizures, tonic-clonic seizures, petit mal seizures, and atonic seizures. The generalized variation is responsible for more than 30% of all epilepsy-related seizures, according to the seizure facts
