The largest collaboration of its kind has found that although epilepsy has many forms, causes and symptoms, making it a very difficult condition to treat, there are many forms of epilepsy which share similar neuroanatomical underpinnings.  Thousands of brain scans from 24 research centres in 14 countries across Europe, North and South America, Asia and Australia were analysed by the Keck School of Medicine of USC in America.  The next stage of research aims to look at the connections between various different areas of the brain and how different medications work for some people and not for others.  More about the research can be found here:
