<qa>  What is a common condition that affects 0.5-1 of the general population?Epilepsy, defined as recurrent, unprovoked seizures, is a common condition, affecting 0.5-1 of the general population. People with uncontrolled epilepsy suffer poor health and increased mortality due to their condition. They frequently experience social stigma and are socioeconomically disadvantaged. It is therefore imperative to help them gain control of their seizures as quickly as possible. A wide range of antiepileptic drugs AEDs has become available to treat people with epilepsy. However, despite maximal therapy, approximately 20-40 show pharmacoresistance PR and thus continue to have seizures.
