Idiopathic generalized epilepsy in adults

Idiopathic epilepsy (IE) accounts for 20% of all epilepsies but less than 1% of research into this disease. This imbalance reflects a lack of awareness of the diagnostic difficulties especially in cases of late onset or atypical signs.We conducted a retrospective study including adults followed for AR. We identified the distinctive clinical and paraclinical criteria of the different syndromes in adults.EI-CGTC was the most frequent epileptic syndrome (78.7%) followed by EMJ (17.32%). Family history of epilepsy and clinical photosensitivity were more frequent in EMJ (p=0.01).Electroencephalographically generalized intercritical abnormalities photo-paroxysmal response and HPN-triggered electrical abnormalities were predominantly recorded during EMJ (p = 0.000 p < 0.05 and 0.001 respectively). Focal abnormalities were recorded during these 2 syndromes. Knowledge of the characteristics of AR syndromes could improve patient management and better guide subsequent epidemiological and genetic studies.
