Facts and Statistics About Epilepsy
- Anyone can be affected by seizures at any age, but epilepsy is most frequently diagnosed in infancy, childhood, adolescence and old age3.
- According to the World Health Organisation, epilepsy is the world's most common serious brain disorder1.
- Epilepsy is more than three times as common as multiple sclerosis, Parkinson’s disease and cerebral palsy.
- Epilepsy is a condition of the brain, not a mental illness.
- It is estimated that nearly 800,000 people in Australia will be diagnosed with epilepsy at some stage in life2.
- It is estimated that over 250,000 Australians are living with epilepsy2. Approx 3% to 3.5% of Australians will experience epilepsy at some point in their lives.
- Approximately 25,000 people in Australia are diagnosed with epilepsy each year.
- An estimated 2.4 million new cases occur each year globally1.
- Around the world an estimated 50 million people have epilpesy at any given time1.
- Epilepsy is diagnosed when the seizures are unprovoked and recurrent – in other words they happen more than once.
- It is commonly thought that epilepsy always involves convulsions. In fact there are
around 40 different types of epilepsy and epilepsy syndromes.
- Incidence of epilepsy in developing countries is almost double that of developed countries.
- Up to 70% of people gain full seizure control with treatment but in developing countries, over 80% of people with epilepsy may not receive the treatment they need.
- A small percentage of people may be eligible for surgery. Approximately 70% of people who have epilepsy surgery become seizure free.
- Treatment options for people who cannot get seizure control with medications include Vagus Nerve Stimulation and the Ketogenic Diet.
- Up to 15% of people referred to an epilepsy specialist centre do not actually have epilepsy and have been previously misdiagnosed.
- People with epilepsy can obtain a driver’s licence if their seizures are controlled by medication or if they fulfil the guidelines set out by the driving authorities.
- Many people outgrow or have a long term remission from seizures. Epilepsy is not necessarily a lifelong disorder.
- Epilepsy can have profound social, physical and psychological consequences.
- People with epilepsy can face social stigma and exclusion. A fundamental part of reducing this stigma is to raise public and professional awareness.
Epilepsy is associated with an increased risk of death, which may be related to:
- An underlying brain disease, such as a tumour or infection.
- Seizures in dangerous circumstances, leading to drowning, burns or head injury.
- Prolonged or ongoing seizures (Status epilepticus).
- Sudden and unexplained causes.
- A possible respiratory or cardio-respiratory arrest during a seizure.
