Rationale: Juvenile absence epilepsy (JAE) and juvenile myclonic epilepsy (JME) are highly heritable idiophathic generalised epilepsy( IGE) syndromes. Employing a functional (fMRI) working memory study, we previously demonstrated  abnormal motor coactivation during with increasing cognitive demand in JME and their healthy siblings, suggestive of a genetically determined, functional imaging trait (Vollmar et al., 2011; Wandschneider et al., 2014). To determine whether this trait is JME syndrome specific, we employed the same task in JAE patients and their unaffected siblings. _x000D_
Methods: We employed a visual-spatial fMRI working memory task (dot back task) in 20 patients with JAE, 18 unaffected siblings and 27 age and sex matched healthy controls. The exploratory threshold is set at p< 0.005, 30 voxels.
