Epilepsy is one of the most common neurological disorders, affecting roughly 50 million people around the world. It’s a condition characterised by seizures which involve episodic, abnormal activity in nerve cells in the brain.
People can have convulsive seizures, where the body stiffens and shakes. There are also more subtle seizures during which people may, for example, lose awareness for short periods of time. While epilepsy always involves seizures, some people can have seizures without being diagnosed with epilepsy.
