    Anything that results in damage or scarring to the brain may lead to seizures and epilepsy. There are many causes for seizures and a thorough diagnostic workup should be done to get an accurate diagnosis.
    Some known causes of epilepsy include:

    • Head injury
    • Stroke or brain haemorrhage
    • Lack of oxygen to the brain for a prolonged period (e.g. birth trauma, cardiac arrest, drug overdose)
    • Brain infections (e.g. meningitis, encephalitis or brain abscess)
    • Brain malformations
    • Brain tumours
    • Genetic factors
    • Conditions affecting the brain (e.g. Alzheimer’s disease)
    • Chronic alcohol or drug abuse
    At least 50% of people with epilepsy will have no known cause for their seizure disorder.
