What is Epilepsy?

Epilepsy is a chronic, neurological condition characterized by recurrent seizures. A seizure happens when abnormal electrical activity in the brain causes an involuntary change in the person’s awareness or behaviour. Epilepsy is diagnosed when a person has had two or more seizures that cannot be attributed to some other condition. Epilepsy is a physical condition, not a mental illness.

Epilepsy most often starts in childhood or in seniors, but anyone can develop epilepsy at any time. Epilepsy affects people of all ages, all nations and all races. Approximately, one in every 100 adults in Ontarians is living with epilepsy ^[1]. In 70% of the cases, the cause of epilepsy is unknown.What is known to cause epilepsy includes brain tumours, serious head injuries and brain infections. In most cases, epilepsy is not inherited, although people with a close family member with epilepsy are at a slightly greater risk. Epilepsy is not contagious.

The goal of all epilepsy treatment is to stop the seizures with as few side effects as possible. The most common treatment is anti-seizure medication. If medication does not work, other options available include brain surgery (in specific cases), an implanted medical device designed to reduce or stop seizures, or a highly specialized diet (recommended more for children than adults).

WHAT IS AN EPILEPTIC SEIZURE?

A seizure is a brief electrical disturbance in the brain. There are many types of seizures, but they are generally classified into two main categories based on which part of the brain is involved. Generalized seizures affect the whole brain. Partial seizures only affect part of the brain.

TYPES OF SEIZURES

Generalized Tonic Clonic (formerly known as Grand Mal)

Tonic clonic seizures are characterized by a fall and rigidity. It is followed by shallow breathing or temporarily suspended breathing, bluish skin and possible loss of bladder or bowel control. The seizure generally lasts a couple of minutes. There may be some confusion and/or fatigue, followed by a return to full consciousness.Absence (formerly known as Petit Mal)

Absence seizures are most common in children. It begins with a blank stare, only lasting a few seconds. The absence seizure may also be accompanied by rapid blinking or chewing movements of the mouth. The child or adult may not be aware of what’s going on during the seizure but quickly returns to full awareness once it has stopped. This type of seizure should not be mistaken for daydreaming or a lack of attention.Focal Seizures with Impaired Awareness (formerly known as Complex Partial)

Focal seizures with impaired awareness usually start with a blank stare, followed by repetitive physical activity. The person appears dazed and may make sounds like muffled speech. While the seizure usually lasts only a few minutes, post-seizure confusion can last substantially longer. This condition should not be mistaken as intoxication.Focal Aware Seizures

Focal aware seizures begin with movement in one area of the body – such as the arm, leg, or face. It cannot be stopped, but the patient stays awake and is aware of what is happening. Spasms may proceed from one area of the body to another and sometimes spread to become a convulsive seizure.

MANAGING EPILEPSY

If you have had a seizure, ALWAYS consult a doctor, preferably a neurologist. Develop a comprehensive care plan with your doctor. Ask Epilepsy Toronto for a free Seizure Journal, where you can record your seizures and medications for each consultation.

Be sure to have your prescriptions filled exactly as prescribed (make sure the pharmacist has not substituted a generic). Take your medication exactly as the doctor instructed. Never skip a dosage of your anti-seizure medication without your doctor’s consent. Use your Seizure Journal to record any side effects and/or changes you see, especially any triggers you notice that cause you to have a seizure. Learn More About Medications.Educate Yourself and Others

The more you know about your condition, the less daunting your treatment becomes. Learn about the causes, treatments, tests, and impacts of epilepsy so you can make the most informed choices for your life. When you visit your doctor, ask for information on your medication’s known side effects, your specific seizure type, and self-management techniques the doctor can suggest.
