Endophenotypification of patients with genetic generalized epilepsy (GGE) A population based study

Short summary

The aim of this study is to define new endophenotypes connected to epilepsy which is difficult to treat, within the cohort of all adult patients from Funen with GGE.



The group of patients with GGE is heterogeneous. Approximately 30 % of all GGE patients suffer from repeated relapse despite anti-epileptic treatment. Knowledge on the cause of the resistance to treatment is very limited. On a genetic level the research of genes causing GGE remains difficult, probably because of the heterogeneity of the disease. This heterogeneity is further complicated because the seizures are only symptoms of a roughly characterized underlying network of diseases connected to dysfunction of the motor cortex. Treatment of patients is mostly based on the principle of "trial and error". Markers, which help predict a fast response to one of the available medicines, would be a significant improvement of the treatment.
