People who have epilepsy have an underlying and permanent alteration in the brain that causes a predisposition to seizures.

Main Similarities

The symptoms of a single seizure are the same as those of epilepsy.

Examples of symptoms that occur along with non-epileptic seizures include:

When Do Seizures Become Epilepsy?

Usually, seizures do not cause epilepsy, but they can be a sign of epilepsy.

This is because a seizure can occur due to a temporary or permanent condition affecting brain function.

Epilepsy happens when a person has certain types of permanent damage in a region of the brain.

Anyone can have a seizure due to severe alterations in neurotransmitters or chemical concentrations in the brain.

Causes and Risk Factors

Certain medical conditions can cause epilepsy and others may cause an individual seizure.

Some causes may overlap and could lead to either one isolated seizure or epilepsy.

Seizure Treatment

If you have a seizure, its important to get prompt treatment.

This may includerapid-acting antiepileptic medication, oxygen supplementation, and checking for any seizure-related injuries.

You would also need treatment for any underlying cause, such as electrolyte abnormalities or a brain tumor.

It’s also important that you maintain lifestyle adjustments to avoid seizure triggers.

Commonantiepileptics (AEDs)for people who have epilepsy include:

Over 40 approved AEDs are available.

Put something soft under their head to protect it (like a folded item of clothing).

Prevention

Prevention is a primary component of managing epilepsy.

Prevention includes lifestyle adjustments and medications.

Preventing Infection

If you have epilepsy, be vigilant about avoiding infectious illnesses.

Even a mild respiratory infection can trigger a seizure for someone who has epilepsy.

Ways to prevent infection include:

Even with these measures, its not uncommon to catch an infection.

Summary

Epilepsy is a medical condition that causes people to have recurrent seizures.

Many people can experience a seizure, even without having epilepsy.

Sometimes, an individual seizure is a sign of a new diagnosis of epilepsy.

Epilepsy is treated with daily antiepileptic medications to prevent seizures and lifestyle measures to avoid triggers.
