Rutgers Health researchers found that lamotrigine, a widely prescribed antiseizure medication, to be safe in older adults with epilepsy, contrary to a safety warning by the Food and Drug Administration (FDA). The study has been published in Neurology.

Algorithms from artificial intelligence (AI) are being used more and more frequently, including for medical diagnosis. However, their potential is barely being tapped in a number of areas. A collaborative project from Universitätsklinikum Erlangen (UKER) at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Gravina Hospital in Caltagirone (Italy) is showing that it does not need to be that way.
